Description

WEARABLE SLEEP MANAGEMENT SYSTEM AND DEVICE, AND METHOD THEREOF

BACKGROUND OF THE APPLICATION

1. Technical Field

The present disclosure generally relates to sleep management, and more particularly to a wearable sleep management system, device, and method thereof.

2. Description of Related Art

Most people have to cope with a busy and tense life in the modern world, and are increasingly suffering from sleep problems. It is thus a continuously discussed issue that how to achieve reasonable and effective management of sleep through more scientific tools and methods.

Existing wearable sleep management devices are often focused on sleep monitoring. For example, CN207707898U discloses a wearable sleep detection instrument, which comprises an electromechanical box, electrode patches, and a data communication base. The electrode patches are connected to the electromechanical box through electrode buckles and are configured to be affixed to the left chest of a user to collect electrocardiogram signals and body movement signals. The electrode patches, classified as accessories of medical electronic instruments, are made of a polymer material, such as plastic, foam, or rubber. These electrode patches are coated with medical adhesive so that they can be directly attached to contact user skin to collect various sensor signals. However, since the known instrument is designed for simple monitoring and data logging, it is incapable of providing any sleep promoting benefit to users with sleep disorders.

There are also sleep promoting devices made wearable, such as those glove-like, head-mounted, and eye-mask-like ones, for giving sleep promoting effects in either a contact manner (e.g., acupuncture or massage) or a non-contact manner (e.g., sounds or light) . For example, CN215135497U discloses a wearable sleep assisting device for sleep medicine, which comprises head clamping piece, earphone storage pieces, a wearable mask, earphone wire clamping pieces and an eyeshade storage piece. The eyeshade storage piece is arranged on the wearable mask. The earphone storage pieces are arranged on two opposite lateral walls of the wearable mask. The earphone wire clamping pieces are located on the earphone storage pieces. The head clamping piece is located on the wearable mask. The earphone wire clamping pieces each have a connecting piece and a connecting wire. The connecting piece is attached to the connecting wire. The connecting piece comprises a radiating net, a rubber layer, a bayonet, and sealing pieces. The rubber layer is formed around the connecting wire. The radiating net is attached to the inner wall of the rubber layer. The bayonet passes through the rubber layer and the radiating layer. The sealing pieces are arranged at two opposite ends of the rubber layer and the radiating net. The relatively large size and relatively complicated structure of the existing device make it less comfortable to use and likely to have components coming off in response to unconscious movements of a user during sleep.

Hence, there is a pressing need for a wearable sleep management device that supports both sleep promoting and sleep monitoring and is compact, easy to wear, and favorable to good sleep comfort.

Meanwhile, as life stress continuously increases, more and more people suffer from somnipathy. According to report from the World Health Organization, 10%to 49%of people worldwide have different levels of insomnia severity. Particularly, the proportion of adults in China with insomnia is as high as 38.2%, making how to improve sleep a hot healthcare topic. In a study, a magnetic field simulating the electroencephalogram rhythm of a sleeping human was applied to heads of 46 subjects with insomnia for magnetic induction, with the attempt to modulate electroencephalogram activity and thereby promote sleep. The experiment involved using toroidal coils to generate a time-varying magnetic field corresponding to electroencephalogram rhythm variations in the process of human sleep, wherein the amplitude of magnetic induction strength Bm was set as 0.015T, with the rise time of 0.1ms and the fall time of 0.6ms. Data were collected from every subject before their use of the experimental magnetic field device for three consecutive days, and during their use of the device at sleep for three consecutive days, so as to show effects of magnetization. The results show that 44 in the 46 subjects experienced reduced latency of sleep onset, with reductions ranging between 10 and 120 minutes, proving the sleep-promoting effects of magnetic induction on people with insomnia particularly in terms of sleep onset and sleep duration. The study further demonstrates that application of magnetic induction was effective in significantly improving groggy feeling and physical fatigue in most of the subjects without causing any adverse effect. In another study, 126 aged subjects with somnipathy were randomly divided into two groups, namely a magnetotherapy group and a control group, each containing 63 subjects. For the subjects in the magnetotherapy group, a magnetotherapy instrument was used once (40 minutes) a day. Two courses of treatment were given, each including 15 consecutive days. The control group did not receive any magnetotherapy. During observation, both of the groups were administrated with γ-aminobutyric acid, oryzanol, and vitamins (other than those for treating organic diseases) . The results showed an excellent response rate of 57%and a good response rate 90%in the magnetotherapy group, compared to 24%and 60%in the control group. The difference is extremely significant (P<0.01) . As to the timing of response onset, 57 cases in the magnetotherapy group came out an average of 7.12±0.35 days, much shorter than 10.15±0.45 days in average as seen in the 38 cases of the control group, making an extremely significant difference (P<0.01) . For the 25 non-response cases in the control group, magnetotherapy was introduced and led to 12 cases of excellent response and 8 cases of improvement. As proven by the study, magnetotherapy is effect in improving somnipathy in aged people with the response onset significantly faster than normal medication.

According to more researches, a static magnetic field can shorten sleep latency, extend deep sleep, and enhance sleep efficiency. Additionally, as reported by a PhD dissertation titled “The Study of Sleep Stages and Low-Frequency Magnetic Field Sleep Induction” from Tianjin University, sleep stimulation was applied to 5 health subjects using a low-frequency pulsed magnetic field (4Hz to 12Hz) and data were assessed against objective indicators. The analysis results show that the result sleep latency was decreased by 9 minutes and the total sleep duration was extended by 25 minutes, with the proportion of deep sleep increased by 9.9%. This demonstrates that a low-frequency magnetic field have sleep-inducing effects and a pulsed magnetic field can promote sleep and change the sleep structure to a meaning for extent.

Somnipathy involves sleep-wake disorder happening when brain neurons in the functional region controlling normal sleep get affected, known as a result of unbalance between excitation and inhibition at the sleep center. According to the modern biomagnetism, diseases happen when the bio-magnetic field in an organism become unbalanced. The central nervous system in a human body is particularly sensitive to magnetism, and tends to receive its inhibitive effects. This makes it practical to correct unbalance at the sleep center using an external magnetic field. Electromagnetic therapy, based on the basically even magnetic permittivity in biological tissues, uses a negative alternating electromagnetic field that has a predetermined rhythm and can passes through the skin and tissues in the brain to stimulate specific regions of the brain, so as to affect bio-potential activities of nerve cells in the stimulated regions and thereby modulate the overall excitation-inhibition process happening in the cerebral cortex. Such an alternating electromagnetic field can help moderate cerebrovascular spasm, promote vasodilatation, and improve vascular elasticity. When acting on cells and blood vessels in the brain, magnetism improves the metabolic environment for brain cells, cell-membrane permeability to ions, and activity of metabolic enzymes, so to renew damaged brain cells and recover brain functions faster. Electromagnetic therapy can be used to obstruct and inhibit occurrence and propagation of abnormal electrical discharge, so as to promote physiological balanced electrical activity of brain, and enhance modulation of the central nervous system by the cerebral cortex, thereby significantly improving sleep quality, and moderating neurasthenia as well as conditions related to brain fatigue.

China Patent No. CN216435574U discloses a rotation/gradient composite magnetic field generating device that relates to the technical field of electromagnetism. The magnetic field generating device therein is composed of a permanent magnet assembly, a driving system, a control system and a heat dissipation system. The permanent magnet assembly has a single permanent magnet or a plurality of permanent magnets in a spatial custom layout. A control system is connected with the permanent magnet assembly through a driving system, and a heat dissipation system is installed beside the driving system. The permanent magnet assembly is formed by installing a permanent magnet on the combined support. The spatial structure of the combined support is designed in a user-defined mode according to needs, and the combined support is prepared through a 3D printing technology.

In the existing device, the driving system drives an x screw rod, a y screw rod, and a z screw rod, so that direction of the generated magnetic field can be adjusted as the change of relative locations among the screw rods. The magnetic field generating device is composed of rods. In particular, the x screw rod, the y screw rod, and the z screw rod are spatially perpendicular to each other. Such a structure, however, is disadvantageous and dangerous because the whole structure supported merely by the driving screw rod tend to topple due to structurally unbalance. When the z screw rod moves along the x screw rod from one end to the other end, the weight of the z screw rod and the fact that it carries the y screw rod, which is also moving simultaneously and reaches the largest arm of force and in turn causes the greatest force acting on the x screw rod when the end of the y screw rod reaches the end of the z screw rod, can make the x screw rod that is a standard part with an even density lose its balance under greater gravity and fall down. Besides, the rods spatially perpendicular to each other make the known magnetic field generating device space-consuming to install and operate, which means that it would be unsuitable for use scenes where space is limited. For example, when a magnetic field generating device is desired to be used beside a bed, such as near the bedhead, the foregoing known device is obviously not a proper and practical choice. Moreover, a sleeping person may have involuntary changes in posture, so that the stretch direction of the spine may change and an included angle can exist between the original and changed directions. As a result, the human body leaves its original location and the magnetic field orientated to the spine direction for the optimal magnetic effect can become inconsistent to the spine direction. In view of this, generation of the magnetic field is preferably made to be adjustable in direction. While the existing magnetic field generating device does support directional change of the generated magnetic field, its structure is less relative to applications where sleep promotion is desired as in the present disclosure, because travel of the device along the x screw rod and the y screw rod is unnecessary and causes a complicated structure as well as additional manufacturing costs. By contrast, a direction-changing mechanism for enabling rotation about a central axis would be more suitable to make the magnetic field direction coincide with the spine stretch direction.

Since there is certainly discrepancy between the existing art comprehended by the applicant of this patent application and that known by the patent examiners and since there are many details and disclosures disclosed in literatures and patent documents that have been referred by the applicant during creation of the present disclosure not exhaustively recited here, it is to be noted that the present disclosure shall actually include technical features of all of these existing works, and the applicant reserves the right to supplement the application with the related art more existing technical features as support according to relevant regulations.

SUMMARY OF THE APPLICATION

In view of the shortcomings of the existing art, the present disclosure provides a wearable sleep management system and method thereof. It further relates to a wearable object, more particularly to a light-stimulation emitting wearable object. Simultaneously, the present disclosure also relates to a wearable sleep-promoting device, more particularly to a wearable sleep management device.

A wearable sleep management system is provided, including a wearable sleep management device body, a sleep monitoring device and a terminal, wherein the wearable sleep management device body and the sleep monitoring device are in communicative connection with the terminal, respectively, the sleep monitoring device collects and sends a first sleep characteristic datum and a first sleep state of a user to the terminal, the terminal generates working parameters according to the first sleep state and a sleep-promoting regimen and sends the working parameters to the wearable sleep management device body in a real-time manner, and the wearable sleep management device body stimulates the user’s body according to the received working parameters so as to cause a sleep state change. The present disclosure achieves improvement in sleep quality by providing stimulation according to sleep state variations through a wearable device.

According to a preferred embodiment, the sleep monitoring device collects the first sleep characteristic datum of the user through a wearable approach and determines the first sleep state. With the user being sleeping, the terminal calibrates a sleep metric of the sleep monitoring device according to a second sleep state determined by a sleep calibrating device. In view that the existing wearable sleep monitoring devices can become more and more inaccurate over time, the present disclosure implements regular calibration to enable a wearable sleep monitoring device to achieve medical-grade sleep monitoring performance.

According to a preferred embodiment, the terminal and the sleep calibrating device are in communicative connection, wherein with the user being sleeping, the terminal receives the sleep metric and the time-related first sleep state from the sleep monitoring device. The terminal further receives the second sleep state coming from the sleep calibrating device, and generates a calibration information for the sleep metric of the sleep monitoring device by taking the second sleep state as a standard result, and feeds the calibration information back to the sleep monitoring device. In the present disclosure, calibration of the sleep metric is conducted by a terminal, so that a portable sleep monitoring device is enabled to achieve medical-grade sleep monitoring performance.

According to a preferred embodiment, the wearable sleep management device causes the sleep state change by controlling at least one light irradiating head to irradiate a light onto at least one acupuncture point on body of the user, and/or controlling a magnetic field generating portion to change a magnetic field.

The present disclosure uses light to apply stimulation on acupuncture points of a human body and thereby significantly improve sleep quality. The stimulation is made to sleep-related acupuncture points in a non-sensory stimulation manner, so as not to incur tactile changes and wake a user of the device. Particularly, it is believed that stimulation applied to Acupoint Shenmen, Acupoint Daling, and Acupoint Neiguan, wherein the three acupuncture points known as the “Golden Triangle for Sleep” is useful in promoting blood circulation and natural release of melatonin, thereby providing sleep-promoting effects. Different from the existing approach that involves performing vibration-based massage on acupuncture points, the present disclosure implements laser-moxibustion and eliminates tactile-feeling changes on user skin, thereby improving user comfort.

The present disclosure can be implemented using any wearable sleep management device that provides an adjustable magnetic field, so that the direction of the generated magnetic field can be changed according to the sleep state of a user to make magnetism best act on the human and improve sleep quality of the user.

According to a preferred embodiment, the wearable sleep management device body has stimulation components, including a first light irradiating head, a second light irradiating head and a third light irradiating head, all the three locationally corresponding to sleep-related acupuncture points on a wrist of the user. In response to the working parameters coming from the terminal, illumination intensity provided by the first light irradiating head, the second light irradiating head and the third light irradiating head of the wearable sleep management device body are determined by the working parameters.

Three light irradiating heads are used to apply light stimulation to the “Golden Triangle for Sleep, ” i.e., Acupoint Shenmen, Acupoint Daling, and Acupoint Neiguan. Preferably, both the irradiation duration and the illumination intensity are controllable according to the working parameters. As light stimulation does not have any physical contact with the skin, it will not cause tactile feeling and foreign body sensation to the user and will not wake the user from sleep.

According to a preferred embodiment, the wearable sleep management device body accommodates therein a substrate for carrying the stimulation components, wherein the first light irradiating head, the second light irradiating head and the third light irradiating head are such installed on the substrate that each of them correspond to at least one of the acupuncture points which are different from each other. The wearable sleep management device body is to be worn around the wrist of a user like a bracelet, and it is possible that the device is not closely fit around the wrist. As a result, the light irradiating heads may become offset with respect to the acupuncture points they are supposed to aim at. To address this issue, the present disclosure uses three light irradiating heads are to extensively cover two or three acupuncture points, so that the three acupuncture points can be stimulated under irradiation for good blood circulation.

According to a preferred embodiment, the substrate further carries biosignal monitoring components, at least including a body temperature sensor, a gravity sensor and a pulse sensor. The present disclosure uses biosignal monitoring components to monitor biological signals related to the body temperature, the heart rate, and the body position of a user during his/her sleep. This can be considered as integrating a wearable sleep management device body and a sleep monitoring device into a unity, and reduces the number of devices to be worn by the user. The monitoring results are transmitted to the terminal through a wireless transmission module for data analysis. Analysis of these biological signals indicates the current sleep status of the user and provides solid data support for assessment of sleep wellness. Further, as compared to glove-like, head-mounted, and eyemask-like wearable devices that are relatively large, the watch-like structure of the disclosed device is unlikely to cause interference with limbs of the user, thereby preforming monitoring without disturbing the user in sleep and eliminating the risk that the otherwise happening disturbance would change the sleep habit of the user and cause extra sleep disorders.

According to a preferred embodiment, the wearable sleep management device body further accommodates therein a PCB, wherein a CPU, an analog-to-digital conversion module, a power management module, a light output control module and a wireless connection module are installed on the PCB. The foregoing hardware components analyze the collected biological signals and the received working parameters, and control the light irradiating heads in terms of illumination intensity, irradiation duration, and on/off state accordingly, thereby enabling the wearable sleep management device body to provide or reduce light stimulation as needed.

According to a preferred embodiment, the wearable sleep management device body is a magnetic field generating device, which modulates a magnetic field direction and a magnetic field strength in response to the working parameters coming from the terminal, so as to facilitate improvement in sleep quality. A static magnetic field is helpful in reducing sleep latency, extending deep sleep, and enhancing sleep efficiency. The magnetic field generated according to the current sleep state can effectively improvement sleep quality. With the working parameters provided by the terminal, the present disclosure can generate and change the magnetic field according to needs, so as to achieve good sleep management without causing any adverse effect.

According to a preferred embodiment, the magnetic field generating device comprises a magnetic field generating portion and a fixing portion, wherein the fixing portion is configured to be installed in a wrist band of wearable sleep management device. The fixing portion includes a rotary disk, an immovable base, and a rotary shaft that connects the rotary disk to the immovable base. The fixing portion is of a split-type structure, and the rotary disk and the immovable base are attached to two ends of the rotary shaft with at least a gap existing therebetween, wherein the gap receives a roller bearing that is connected to a connecting pole on a lower surface of the rotary disk so that the roller bearing contacts both the rotary disk and the immovable base.

When not in use, the disclosed magnetic field generating device has the rotary disk supported by the roller bearing, so that the rotary disk can stay stable on the immovable base and does not tilt even under an external force. In use of the disclosed magnetic field generating device, the roller bearing can further stabilize rotation of the device. In particular, the roller bearing helps share the force acting on and the weight born by the rotary disk, so as to ensure stable rotation of the rotary disk and prevent the rotary disk from tilting. Additionally, the roller bearing facilitates smooth rotation of the rotary disk, particularly during low-and middle-speed rotation, so as to prevent interruption of rotation. Since the disclosed magnetic field generating device is designed to achieve more stable rotation, as described previously, it ensures the stability of the generated magnetic field, thereby preventing instable rotation and consequent magnetic deviation or jitter. Once the magnetic field is instable, the magnetism it applies to the human body can have deviation and jitter and fail to function as expected. In a worse case, an instable magnetic field can adversely affect the cardiac magnetic field, the brain magnetic field, and the neuronal magnetic field of the user, and make physiological parameters of the user instable or even adversely affect sleep of the user. The magnetic field generating device of the present disclosure effectively prevents generation of such an instable magnetic field and its consequences by securing stable rotation.

The present disclosure also provides a wearable-device based sleep management method, which includes the following steps: communicatively connecting a wearable sleep management device body and a sleep monitoring device to a terminal, respectively; making the sleep monitoring device collect and send a first sleep characteristic datum and a first sleep state of a user to the terminal; making the terminal generate working parameters according to the first sleep state and the sleep-promoting regimen and send the working parameters to the wearable sleep management device body in a real-time manner; and making the wearable sleep management device body operate according to the receives working parameters to stimulate the user’s body so as to cause a sleep state change.

To address the problem of the existing wearable sleep monitoring devices about less accurate results and failure in providing effective sleep intervention, the disclosed method enables effective sleep management and intervention using a terminal, so as to allow the wearable sleep management device body to effectively improve sleep quality.

According to a preferred embodiment, the inventive method further includes: putting the terminal and the sleep calibrating device in communicative connection; and with the user being sleeping, making the terminal calibrate a sleep metric of the sleep monitoring device according to a second sleep state determined by the sleep calibrating device. With the sleep metric of the sleep monitoring device calibrated against a medical-grade sleep calibrating device, the present disclosure solves the problem of a portable sleep monitoring device about inaccurate monitoring results.

According to a preferred embodiment of the disclosed method, with the user being sleeping, the terminal receives the sleep metric and the time-related first sleep state from the sleep monitoring device. The terminal further receives second sleep state from the sleep calibrating device, and generates a calibration information for the sleep metric of the sleep monitoring device by taking the second sleep state as a standard result, and feeds the calibration information back to the sleep monitoring device.

DETAILED DESCRIPTION OF THE APPLICATION

The present disclosure will be described in detail with reference to the accompanying drawings.

Existing wearable sleep management devices have some shortcomings: (1) they usually perform sleep intervention and management in the way that they contact the body of the user, and may wake the user from sleep during operation, making their use experience far from satisfying; and (2) their monitoring components are less accurate and the resulting inaccurate results can backfiringly lead to improper sleep intervention.

It is thus clear that good sleep management necessitates a sleep monitoring device 500 that can accurately determine the sleep state and a wearable sleep management device body 100 that provides effective sleep management without sensory stimulation. The sleep monitoring device 500 and the wearable sleep management device body 100 may directly interact with each other, ore may have indirect interaction through a terminal 600.

Embodiment 1

The present embodiment provides a wearable sleep management system. As shown in FIG. 6, the system comprises a wearable sleep management device body 100 and a sleep monitoring device 500 that are in communicative connection with each other.

The sleep monitoring device 500 is configured to be worn by a user on, for example, his/her or wrist to collect a first sleep characteristic datum of the user and accordingly determined a first sleep state of the user. The first sleep state refers to the real-time sleep state of the user, and is a dynamic information. The first sleep state may involve information about sleep profiles, time of sleep profiles, time periods, sleep cycles, sleep profile variations.

The first sleep characteristic datum may include data signals of the body temperature (T) , movements (S) , the heart rate (H) , and the respiratory rate (R) . The data signals of the body temperature (T) , movements (S) , the heart rate (H) , and the respiratory rate (R) may be stored in a way that they are related to time or frequency. The sleep monitoring device 500 may, for example, be a wearable sleep monitor. The sleep monitor may be hand-held, watch-like, neck-mounted, or head-fit. The sleep monitoring device 500 may, for example, be a wearable electronic device, such as a smart bracelet or a smart watch. Preferably, the sleep monitoring device 500 computes and analyze the first sleep characteristic datum and the sleep metric so as to determine the sleep state and its dynamics.

The wearable sleep management device body 100 is configured to be worn by a user or installed around a user, so as to stimulate the body of the user and improve sleep quality without sensory stimulation, thereby achieving good sleep management. Therefore, the stimulation will not making any sensory feeling, so the user will not feel any sensory stimulation, such as causing tactile changes or making new tactile feeling, thereby avoiding waking the user from sleep.

Preferably, the sleep management device main body 100 and the sleep monitoring device 500 may be integrated into the same device, so as to reduce the number of devices the user has to wear and make the resulting device compact and less complex.

The wearable sleep management device body 100 can determine the working parameters of the wearable sleep management device body 100 based on the first sleep state and the sleep-promoting regimen and apply stimulation on the body of the user accordingly.

The foregoing sleep management for a user is achieved on the basis that the wearable sleep management device body 100 and the sleep monitoring device 500 are consistent in terms of communication method, data format, and programming method, so that the two can have direct information interaction therebetween. Nevertheless, in real-world scenarios, a user may buy the wearable sleep management device body 100 and the sleep monitoring device 500 of different specifications and communication protocols from different manufacturers at different time points. In such a case, the wearable sleep management device body 100 and the sleep monitoring device 500 may have problems reading or analyzing data from each other due to their incompatible languages, and fail to work together for sleep management.

There is thus a need for an intermediate device to accomplish analysis and interaction of information. The intermediate device can communicate with the wearable sleep management device body 100 and the sleep monitoring device 500, respectively, and can perform data computing and data analysis. In the present disclosure, the terminal 600 is configured to perform reception, analyses and interaction for data coming from different devices. The terminal 600 may be a smartphone, a computer, a tablet, etc. The terminal 600 has built-in data processing capability. Alternatively, the terminal 600 performs data analysis and data processing, or even generates the working parameters through a server or a service platform it is remotely connected to. In the present disclosure, the terminal 600 may be equipped with a sleep monitoring module that is in communicative connection with the sleep monitoring device 500 and is configured to conduct sleep state analysis. The terminal 600 may further have a sleep management module that is in communicative connection with the wearable sleep management device body 100 and can generate the working parameters according to the sleep-promoting regimen and the first sleep state. Preferably, the sleep-promoting regimen may be retrieved by the terminal 600 or the wearable sleep management device body 100 from a remotely connected database. Preferably, with permission and authorization of the sleep monitoring module, the sleep management module can directly extract the first sleep state generated by the sleep monitoring module, so as to achieve dynamic management and intervention for the sleep state of the user.

In the present disclosure, as shown in FIG. 6, the wearable sleep management device body 100 and the sleep monitoring device 500 are in communicative connection with the terminal 600, respectively.

In an example where the sleep monitoring device 500 is capable of conducting sleep state analysis, it sends the first sleep characteristic datum and the first sleep state of the user it collects to the terminal 600. Alternatively, if the sleep monitoring device 500 is incapable of conducting sleep state analysis, it sends the first sleep characteristic datum of the user it collects to the sleep monitoring module in the terminal 600. The sleep monitoring module then analyzes the first sleep characteristic datum and determines the first sleep state accordingly. The computing method or computing model used to determine the first sleep state according to first sleep characteristic datum is preprogrammed in the sleep monitoring module or in a remote server or service platform.

Upon receiving or being input with a sleep-promoting regimen, the sleep management module in the terminal 600 checks the first sleep state from the sleep monitoring module in a real-time manner or regularly, and generates the working parameters of the wearable sleep management device body 100 according to the first sleep state, the sleep-promoting regimen, and the component parameters of the wearable sleep management device main body 100.

The wearable sleep management device body 100 operates according to the working parameters it receives so as to stimulate the body of the user and thereby facilitate the sleep state change. Specifically, the terminal 600 sends the working parameters to the control module of the wearable sleep management device body 100 in a wired or wireless manner, so that the control module controls components in the wearable sleep management device body 100 according to the working parameters, thereby making the wearable sleep management device body 100 apply stimulation to the body of the user and helping improve sleep quality of the user.

In the present disclosure, the wearable sleep management device performs the sleep state change by: controlling at least one light irradiating head to irradiate light onto acupuncture points on the human body; and/or controlling a magnetic field generating portion to change its magnetic field. The both approaches may be used together or each of them may be implemented alone.

In an example where the wearable sleep management device body 100 performs the sleep state change by stimulating acupuncture points on the human body with light, the wearable sleep management device body 100 can modulate its irradiating intensity, light luminance, and irradiating duration according to the working parameters it receives in a real-time manner. The light stimulation can promote blood circulation of the user and thereby change the sleep state. When the sleep management module determines that the sleep state of the user has changed to the desired one according to the extracted first sleep state, the sleep management module in the terminal 600 sends a command to the wearable sleep management device body 100 to stop irradiation, so that the wearable sleep management device body 100 turns off the light irradiating components. In an example where the wearable sleep management device body 100 performs the sleep state change by changing the magnetic field to stimulate relevant acupuncture points on the body of the user, the wearable sleep management device body 100 adjusts the magnetic field in terms of direction and field strength according to the working parameters it receives in a real-time manner. The stimulation caused by the magnetic field can promote blood circulation of the user and thereby change the sleep state. When the sleep management module determines that the sleep state of the user has changed to the desired one according to the extracted first sleep state, the sleep management module in the terminal 600 sends a command to the wearable sleep management device body 100 to stop irradiation, so that the wearable sleep management device body 100 turns off its magnetic field generating components.

As described previously, the wearable sleep management system of the present disclosure can control the working mode of the wearable sleep management device body 100 according to the current first sleep state of the user and the sleep-promoting regimen, so that the wearable sleep management device body 100 can apply appropriate light stimulation or magnetic stimulation to improve the sleep state of the user, thereby achieving effective sleep management for the user.

The foregoing implementation of the wearable sleep management system is based on the accurate determination of the sleep state of the user made by the sleep monitoring device 500 and the terminal 600. In the objective real world, the progress of the sleep monitoring device 500 acquired by the user is behind the monitoring progress of medical instruments, so the first sleep state it determined according to the first sleep characteristic datum and the sleep metric may be different from the actual sleep state of the user. The first sleep state determined by the sleep monitoring device 500 and the terminal 600 may be more and more inaccurate after long use of the sleep monitoring device 500. In case of such difference, the light or magnetic stimulation applied by the wearable sleep management device body 100 may fail to change the sleep state as expected, leading to sleep management below expectations. To address this objective issue, the present disclosure further provides a method and system that can enable the sleep monitoring device 500 to determine the first sleep state accurately.

As shown in FIG. 6, the terminal 600 is in wired or wireless communicative connection with the sleep monitoring device 500 and the sleep calibrating device 700, respectively. With the user being sleeping, the terminal 600 calibrate the sleep metric of the sleep monitoring device 500 against a second sleep state determined according to the sleep calibrating device 700.

Specifically, with the user being sleeping, the terminal 600 receives the sleep metric and the time-related first sleep state from the sleep monitoring device 500.

The sleep calibrating device 700 collects the second sleep characteristic datum related to the user as electroencephalogram wave data. The several electrodes of the sleep calibrating device 700 are connected to the frontal pole of the user to collect electroencephalogram signals, electrooculogram signals, and electromyogram signals related to the user. The sleep calibrating device 700 comparatively analyzes the pre-processed electroencephalogram data and a sleep data model preloaded in the connected database, thereby determining the second sleep state or sleep quality of the user.

Generally speaking, existing sleep monitors like the sleep calibrating device 700 typically employs bioelectric signals (e.g., electroencephalogram signals) to work. Since electroencephalogram has been scientifically recognized as the golden rule for assessing sleep wellness, medical-grade sleep monitoring equipment based on electroencephalogram is advantageous in view of its high detection precision and accuracy and extensively used in hospitals and high-end clinics. However, this is particularly inconvenient to people with disabilities because it requires a user to frequently visit the hospital or clinic for measurement and treatment. In addition to considerable time and efforts spent by users for the foregoing visits, a further disadvantage of the known approach is that the high costs for acquisition and maintenance the medical organization pays can be eventually passed to the user through his/her medical bill. The present disclosure uses the sleep calibrating device 700 to calibrate the monitoring results of the sleep monitoring device 500 regularly or as frequent as need, so that the portable wearable sleep monitoring device is enabled to provide more accurate sleep monitoring results, thereby eliminating the need of replacing the existing sleep monitoring device 500 with a precise new device.

The terminal 600 receives the second sleep state from the sleep calibrating device 700. The sleep calibrating device 700 may be an electroencephalogram sleep monitor used in a hospital or a clinic. Specifically, the sleep calibrating device 700 may be, for example, a polysomnography system. Specially, the s sleep calibrating device 700 can determine sleep profiles of users at least according to electroencephalogram signals. Alternatively, the sleep calibrating device 700 may determine the sleep profile of a user according to at least two forms of signal selected from electroencephalogram, electrooculogram, and electromyogram.

The terminal 600 takes the second sleep state as the standard result and accordingly generates the calibration information for the sleep metric of the sleep monitoring device 500. Then it feeds the calibration information back to the sleep monitoring device 500. Specifically, the terminal 600 compares the first sleep profile and the second sleep profile to determine a difference therebetween, and generate the calibration information for the sleep metric of the sleep monitoring device 500 accordingly, so that the sleep monitoring device 500 can correct the monitoring result with respect to the first sleep profile the calibration information.

Preferably, the terminal 600 determines the first sleep profile and the second sleep profile in the same sleep cycle in a time-based manner. For the same sleep cycle, the difference between the first sleep profile and the second sleep profile is determined through comparison.

In order to get more accurate sleep metrics, the terminal 600 uses differences between the first sleep profile and the second sleep profile over multiple sleep cycles to generate the calibration information for the sleep metric of the sleep monitoring device 500. According to a preferred mode of the present disclosure, the calibration information for the sleep metric of the sleep monitoring device 500 includes one of the followings: a replacement information about the sleep metric and an adjustment difference of the sleep metric. The replacement information about the sleep metric refers to a new sleep metric that replaces the old sleep metric, and is an updated sleep metric. The adjustment range of the sleep metric refers to a difference value by which an adjustment shall be made to a sleep metric. As a result of adjusting the old sleep metric using the adjustment difference, a newly formed sleep metric is used to monitor and assess new first sleep state characteristic datum, so that the determined first sleep profile is identical or almost identical to the second sleep profile.

The terminal 600 sends the calibration information for the sleep metric to the sleep monitoring device 500 directly. The sleep monitoring device 500 calibrates the sleep metric according to the received calibration information about the sleep metric, thereby obtaining more accurate monitoring results related to the first sleep profile.

As described previously, in order to overcome the shortcomings of existing portable sleep-monitoring devices that have been seen in home use scenarios, the present disclosure uses a highly precise and accurate medical-grade sleep-monitoring instrument to calibrate the first sleep state ad its sleep metrics solely determined by a portable sleep-monitoring device. For example, correcting one or more kinds of the metrics, such as sleep quality indexes, sleep efficiency, sleep onset latency, sleep fragmentation and/or other indicators, can be corrected so as to provide users with accurate and reliable sleep assessment. Further, by using a medical-grade sleep-monitoring instrument to verify accuracy of the first sleep state determined by a portable sleep-monitoring device, the present disclosure effectively ensures and maintains high accuracy of a portable sleep-monitoring device for home use, and, according to the correctly determined sleep state of a user, provides a reliable basis for selection of relevant sleep promoting measures, such as provision of a time-varying magnetic or electric field relevant to the sleep state of the user.

Embodiment 2

To address the shortcomings of the art known by the inventor, the present disclosure provides a wearable sleep management device. Based on the principles of moxibustion and meridian as adopted in the Chinese medicine, the present disclosure involves applying non-contact massage to the so-called “Golden Triangle for Sleep” , namely Acupoint Shenmen, Acupoint Daling, and Acupoint Neiguan. Herein, the non-contact massage is preferably light-moxibustion achieved using light irradiation in a specific frequency band. As described previously, light-moxibustion massage applied to Acupoint Shenmen, Acupoint Daling, and Acupoint Neiguan is useful in promoting blood circulation and natural release of melatonin, thereby providing sleep-promoting effects. Further, the present disclosure further uses monitoring components to monitor various biological signals related to a user during sleep, so as to provide solid data support for assessment of sleep wellness. The disclosed device primarily comprises a wearable sleep management device body 100 and a wrist band 200.

As shown in FIG. 2, the wrist band 200 is made of a flexible material so that it can be bent along and fit on the wrist. The wrist band 200 has its one end fixedly connected to the wearable sleep management device body 100 and the opposite end configured into a free end 201 that works with the wearable sleep management device body 100 to form a relatively wide opening so as to allow a user to mount the wrist band 200 around the wrist easily. Specially, the free end 201 of the wrist band 200 is detachably connected to the wearable sleep management device body 100 through a fastening component. Preferably, the free end 201 of the wrist band 200 is formed as a clip 203 and a matching fastener 202 is provided at the lateral of the wearable sleep management device body 100 so that the wrist band 200 and the wearable sleep management device body 100 can be held together. In the present embodiment, the wrist band 200 only has one free end 201, thereby preventing the wearable sleep management device body 100 from leaving the user during its handling and putting on/off.

Alternatively, the wrist band 200 may have its two ends both formed as free ends. In this case, two laterals of the wearable sleep management device body 100 are provided with fastening components matching them. This allows full separation between the wrist band 200 and the wearable sleep management device body 100, making the device convenient to store after use and convenient to charge.

As shown in FIG. 2, the wrist band 200 is further provided with a positioning portion 204 that is used to hold the wrist pisiform bone in position. The positioning portion 204 is installed on the wrist band 200 and is separated from the end of the wrist band 200 by a first distance. Herein, the first distance refers to a distance between the pisiform bone in the wrist and the internal center of the wrist along the peripheral surface of the wrist. Further, the positioning portion 204 is shaped to match the pisiform bone and has a curved, protruding outward surface. Thereby, when wearing the wrist band 200, the user can put it in position fast and correctly. A user using the device can simply wear it and ensure that the stimulation components correspond the relevant acupuncture points by mounting the positioning portion 204 around his/her pisiform bone, and bend the wrist band 200 along his/her wrist to connect the wrist band 200 to the wearable sleep management device body 100 without performing any additional aligning operation. Besides, the positioning portion 204, when mounted around the pisiform bone, can further help prevent the wrist band 200 from sliding on or coming off from the wrist.

According to a preferred mode of the present disclosure, the wrist band 200 comes with three different length specifications to fit users of different genders and different ages who have different wrist circumferences and in turn different lengths of the first distance. On the wrist band 200, the distance defining the location of the positioning portion 204, namely the first distance, is made with three versions, including a first length, a second length, and a third length. Preferably, the first length is in the range of 3.2 to 4.5cm to fit the wrist size of children. The second length is in the range of 4 to 5.3cm to fit the wrist size of female adults. The third length is in the range of 5 to 6.5cm to fit the wrist size of male adults.

According to a preferred mode of the present disclosure, as shown in FIG. 1 and FIG. 2, the wearable sleep management device body 100 is a box formed by an upper casing 111 and a lower casing 101 so that an accommodating space is defined therein to accommodate therein a PCB 102, a battery 103, a substrate 104, stimulation components, and biosignal monitoring components. The upper casing 111 is in direct contact with the inner side of the wrist. The lower casing 101 and the upper casing 111 are combined together through threads and a sealing ring arranged therebetween. The substrate 104 carries the stimulation components and the biosignal monitoring components. It has a cross-sectional shape identical to the surface shape of the upper casing 111 and the cross-sectional shape of the inner wall of the lower casing 101. Further, the upper casing 111 is formed with several through-holes having different shapes so that the stimulation components and the biosignal monitoring components can be exposed outside the upper casing 111 to perform their light-moxibustion and monitoring functions.

According to a preferred mode of the present disclosure, as shown in FIG. 1, the stimulation components include the first light irradiating head 105, the second light irradiating head 106, and the third light irradiating head 107, locationally corresponding to Acupoint Neiguan, Acupoint Daling, and Acupoint Shenmen at the inner side of the wrist, respectively. The first light irradiating head 105, the second light irradiating head 106, and the third light irradiating head 107 are all installed on the substrate 104.

Referring to FIG. 4, for easy description, the center line of the wrist is herein named as the first reference line, and the symmetry center line of the extending direction of the wrist band 200 is named as the second reference line. The first reference line and the second reference line jointly divide the substrate 104 into four quadrants. Since the substrate 104 and the upper casing 111 are connected coaxially, the first reference line and the second reference line also divide the upper casing 111 into four quadrants. The quadrant close to the palm and close to the pisiform bone is herein referred to as the reference quadrant. The first light irradiating head 105, the second light irradiating head 106, and the third light irradiating head 107 are arranged as below. The third light irradiating head 107 is located in the reference quadrant and is separated from the first reference line and the second reference line by a distance of 10 to 25mm, respectively. The second light irradiating head 106 is located on the first reference line, and its link to the third light irradiating head is parallel to the second reference line. The first light irradiating head 105 is located on the first reference line, and is separated from the second light irradiating head in a direction far from the palm by a distance of 25 to 55m. For light-moxibustion, the present disclosure uses low-intensity laser to irradiate the foregoing acupuncture points, and is advantageous for being pain-free, germ-free, convenient, safe, and intensity adjustable.

According to a preferred mode of the present disclosure, as shown in FIG. 1, the body temperature sensor 108, the gravity sensor 109, and the pulse sensor 110 for monitoring biosignals are also installed on the substrate 104. The body temperature sensor 108 serves to monitor the body temperature of the user. The gravity sensor 109 serves to monitor variations of the body position and posture of the user during sleep. The pulse sensor 110 serves to monitor the heart rate of the user.

According to a preferred mode of the present disclosure, as shown in FIG. 1, the upper casing 111 is formed with several through-holes. These are a first through-hole 112, a second through-hole 113, and a third through-hole 114 that match the first light irradiating head 105, the second light irradiating head 106, and the third light irradiating head 107 in location and in shape, respectively, so that the light irradiating heads can be exposed outside the upper casing 111 and provide light-moxibustion to the corresponding acupuncture points. The upper casing 111 is further provided with a through-hole 115 for body temperature sensor, a through-hole 116 for gravity sensor, and a through-hole 117 for pulse sensor that correspond to the body temperature sensor 108, the gravity sensor 109, and the pulse sensor 110 in both location and shape, so that the sensors can all pass through the upper casing 111 to collect the required biological signals.

According to a preferred mode of the present disclosure, as shown in FIG. 3, the PCB 102 is installed with a CPU, an analog-to-digital conversion module, a power management module, a light output control module, and a wireless connection module. The analog-to-digital conversion module has its input end connected to the outputs of the body temperature sensor, the gravity sensor, and the pulse sensor for receiving analog signals these sensors collect. Its output is connected to the CPU so as to send the digital signals, as a product of analog-to-digital conversion, to the CPU. The power management module is connected to the battery and the CPU. The battery is preferably a rechargeable 12V lithium battery. The power management module serves to automatically switch the battery between its charging and discharging modes to protect the battery from being overcharged. The light output control module has its input end connected to the CPU to receive light-moxibustion modulation commands from the CPU. Its output is connected to the first light irradiating head 105, the second light irradiating head 106, and the third light irradiating head 107, so as to adjust the light intensity and irradiating duration of each of the light irradiating heads. The wireless connection module is connected to the CPU so that the disclosed sleep management device can be wirelessly connected to a mobile client of the user. The wireless connection module may be a Bluetooth module or a Wi-Fi module.

Embodiment 3

The present embodiment provides further improvements on Embodiment 1, and repeated details are omitted from the description thereof.

The present disclosure provides a magnetic field generating device. As shown in FIG. 5, it comprises a magnetic field generating portion 300 and a fixing portion 400. The magnetic field generating device of the present disclosure may be installed in a ring-like object for a user to carry with him/her. The fixing portion 400 adjusts the magnetic field direction through a rotary disk.

As shown in FIG. 5, the fixing portion 400 is composed of the rotary disk 401 and an immovable base 402. According to a preferred mode of the present disclosure, the magnetic field generating portion 300 may be configured as coil components. With an electric current passing through the coil components, the coil components can generate an electromagnetic field, which in turn acts a user. The coil components of the magnetic field generating portion 300 are arranged around an iron core, so that the coil components when electrified can increase the magnetic field strength. The coil components evenly wrap around the iron core along the axial direction of the iron core, so that the magnetic field generating portion 300 can generate a magnetic field that is more uniform. The use of the coil components as the magnetic field generating mechanism allows the power source connected to the coil components to be turned on or off according to practical needs, thereby dynamically adjusting the working state of the magnetic field generating portion 300. Additionally, the magnetic field generating portion 300 may further achieve flexible adjustment of the magnetic field strength by adjusting the number of turns of the coil components and the electric current intensity. Preferably, the magnetic field generating portion 300 is further provided with a protective shell for preventing particles and dust from being sucked and entering the magnetic field generating portion 300 during generation of the magnetic field, so as to ensure that the electric current can pass smoothly and the magnetic field can be generated effectively.

According to a preferred mode of the present disclosure, depending on use scenes and requirements for the generated magnetic field, the magnetic field generating portion 300 may be a permanent magnet. In this case, the magnetic field generating portion 300 can generate a stable magnetic field without requiring an external power source, so that the magnetic field can act on the user consistently and stably.

According to a preferred mode of the present disclosure, the rotary disk 401 of the fixing portion 400 is configured as a round plate structure for carrying the magnetic field generating portion 300. The round plate structure is a standard part and has a balanced mass, so that it can rotate about its own center without biasing. The upper surface of the rotary disk 401 is detachably connected to the magnetic field generating portion 300, and the round plate structure has a transverse section area at least greater than that of the magnetic field generating portion 300, so that the round plate structure can well carry the magnetic field generating portion 300. Preferably, the upper surface of the rotary disk 401 is adhered to or clipped onto the magnetic field generating portion 300, so that when the round plate structure is rotated by the rotary shaft, the magnetic field generating portion 300 can be driven by the round plate structure to rotate, thereby changing the magnetic field direction. The lower surface of the rotary disk 401 is centrally formed with a screw nut structure. In the process that the disclosed magnetic field generating device adjusts the magnetic field direction, the screw nut on the lower surface of the rotary disk 401 comes into screw-nut fit with the rotary shaft, so that when the rotary shaft driven by the motor to rotate, the rotary disk 401 connected to the rotary shaft can also be driven to rotation, thereby achieving adjustment of the magnetic field.

According to a preferred mode of the present disclosure, the immovable base 402 and the rotary disk 401 of the fixing portion 400 are assembled as a split-type structure. The immovable base 402 is of a hollow, round-table structure whose upper surface is provided with a hole for the rotary shaft to pass therethrough. The rotary disk 401 is of a round-plate structure. The transverse section area of the lower surface of the rotary disk 401 is equal to that of the upper surface of the immovable base 402 of the round table structure, and the center of the rotary disk 401 coincides with that of the immovable base 402 so that the rotary shaft installed in the immovable base 402 have connection with the screw nut at the lower surface of the rotary disk 401 through the hole at the center of the upper surface of the immovable base 402. Preferably, at least a gap of a certain size is formed between the immovable base 402 and the rotary disk 401, so that during rotation of the rotary disk 401, the immovable base 402 can stay still without driving by the rotary disk 401 to rotate. This allows the immovable base 402 and the rotary disk 401 to maintain their respective, different movement states. The immovable base 402 is provided therein with a rotary shaft connected to the rotary disk 401. The rotary shaft has its one end fixedly connected to the screw nut at the lower surface of the rotary disk 401. When the rotary disk 401 is rotated by the rotary shaft, the rotary shaft connected to the center of the rotary disk 401 can transmit the rotation power efficiently, thereby minimizing energy loss and effectively preventing the rotary disk 401 from bias rotation due to center of gravity shift. The other end of the rotary shaft is connected to the motor installed in the fixing portion 400, so that rotation of the motor drives the rotary shaft to rotate, thereby driving the rotary disk 401 connected to the rotary shaft to rotate. When the rotary shaft is connected to the motor, the rotary shaft has an axial height at least greater than the height of the fixing portion 400. In other words, when the rotary shaft is working, the rotary shaft can at least pass through the hole at the upper surface of the immovable base 402, so that a gap is formed between the immovable base 402 and the rotary disk 401 to prevent the two from interfering with each other due to their different movements. When generating a magnetic field, the disclosed magnetic field generating device can, in response to a postural change of the user, activates the motor to drive the magnetic field generating portion 300 to rotate, thereby changing the direction in which the magnetic field generated by the magnetic field generating portion 300 acts on the user, thereby realizing adjustment of the magnetic field direction.

According to a preferred mode of the present disclosure, the rotary disk 401 and the immovable base 402 are such attached to two ends of the rotary shaft that at least a gap exists therebetween. The gap is encircled by roller bearings 403. The roller bearings 403 are such connected to the connecting pole 404 at the lower surface of the rotary disk 401 that they contact both the rotary disk 401 and the immovable base 402. Thereby, in the process that the rotary disk 401 rotates, the roller bearings 403, due to their contact with the lower surface of the rotary disk 401 and the upper surface of the immovable base 402, rotate along the circumferential direction of the rotary shaft. This not only ensures smooth rotation of the rotary disk 401 but also further stabilize the rotation. Moreover, connecting poles 404 for connecting the roller bearings 403 is provided on the lower surface of the rotary disk 401. The connecting poles 404 each have its one end connected to the shaft-like structure of at the lower surface of the rotary disk 401, and the shaft-like structure extends from the lower surface of the rotary disk 401 to the upper surface of the immovable base 402 without contacting the upper surface of the immovable base 402. Preferably, the connecting poles 404 are arranged at two points that are at the same diameter and are symmetrical about the center of the rotary disk 401. The two points are separated by a distance as long as the radius of the rotary disk 401. Further, the connecting poles 404 is circumferentially provided with transverse beams for holding the roller bearings 403. The transverse beams each pass through the connecting poles 404 and have an axis perpendicular to the axis of the connecting pole 404, so that the roller bearings 403 can be such fit onto the transverse beams of the connecting poles 404 that they precisely contact the lower surface of the rotary disk 401 and the upper surface of the immovable base 402. Thereby, when the rotary disk 401 rotates, the roller bearings 403 can, in response to rotation of the rotary disk 401, rotate along the circumferential direction of the rotary shaft, and in turn the roller bearings 403 fit into the transverse beams of the connecting pole 404 can help stabilize the rotation. Preferably, every connecting pole 404 works with two roller bearings 403, and the transverse section of the roller bearing 403 is always perpendicular to a radius of the rotary disk 401.

According to a preferred mode of the present disclosure, the rotary disk 401 of the fixing portion 400 is further provided with a pinion-rack transmission mechanism. The pinion-rack transmission mechanism serves to adjust the magnetic field generating portion 300 in height, thereby changing the magnetic flux acted on the user by the magnetic field generating portion 300 to advantageously adapt the device to people with different sensitivity levels. For example, in a use scene where the number of turns of the coils in the magnetic field generating portion 300 and the charge passed are fixed and cannot be adjusted, the disclosed magnetic field generating device can still adjust the magnetic flux acting on a user by changing the height of the magnetic field generating portion 300, thereby advantageously achieving flexible adjustment and convenience of use. Specifically, the pinion-rack transmission mechanism is installed at the upper surface of the rotary disk 401. The rack is received in a slide that is vertically fixed at the center of the rotary disk 401 and has a fillister. The fillister of the slide has a depth that is equal to the thickness of the rack, and the length of the slide is at least greater than the length of the rack.
