Hereinafter, the present invention will be described in detail with reference to the attached drawings.

FIG. 1 is a schematic diagram of a wearable device and a charger according to an embodiment of the present invention, and FIG. 2 is a schematic diagram of the configuration of a wearable device according to an embodiment of the present invention. Here, (a) of FIG. 1 is a schematic diagram of a wearable device of the present invention, and (b) of FIG. 1 is a schematic diagram of a charger of the present invention.

As shown in FIGS. 1 and 2, the wearable device of the present invention includes a housing (160) having a ring shape and an internal space; a sensor unit (110) coupled to the housing (160) and in contact with the user's skin to measure the user's pulse wave; a communication unit (130) that receives and processes a signal from the sensor unit (110) to generate a transmission signal, which is a transmitted signal; and an analysis unit (120) that receives and analyzes the transmission signal. In addition, the analysis unit (120) can analyze the user's pulse wave information to determine the user's glaucoma symptoms.

The housing (160) has a ring shape and can be worn on the user's finger, and accordingly, the inner surface of the housing (160) can be in contact with the user's finger skin. The outer surface of the housing (160) exposed to the outside can be formed of a metal material such as titanium or stainless steel (SUS), and the inner surface of the housing (160) can be formed of a non-metal such as plastic. However, the material forming each part of the housing (160) is not limited thereto, and it goes without saying that various materials can be used.

The wearable device of the present invention may further include a vibration unit (140) that receives an operating signal from an analysis unit (120) and transmits vibration to the user's skin to transmit a health abnormality signal to the user.

Specifically, when the analysis unit (120) determines that the user has glaucoma through the following process, the analysis unit (120) transmits an operating signal to the vibration unit (140), and the vibration unit (140) generates vibration in response to the operating signal, so that the vibration is transmitted from the vibration unit (140) to the user's skin, and thereby the user can recognize that he or she has glaucoma.

The wearable device of the present invention may further include an elastic member formed in the internal space of the housing (160) to allow the sensor unit (110) to come into close contact with the user's skin and to allow the vibrating unit (140) to come into close contact with the user's skin.

The elastic member may include a first elastic body (151) that has elasticity and is formed in the internal space of the housing (160) and is combined with the sensor member (110) to press the sensor member (110) toward the center of the housing (160), and a second elastic body (152) that has elasticity and is formed in the internal space of the housing (160) and is combined with the vibrating member (140) to press the vibrating member (140) toward the center of the housing (160).

As shown in Fig. 2, a portion of the sensor portion (110) may protrude on the inner surface of the housing (160), and a portion of the vibrating portion (140) may also protrude on the inner surface of the housing (160).

And, when the user's finger is inserted into the housing (160), the skin of the user's finger presses the protruding portion of the sensor portion (110) and the protruding portion of the vibrating portion (140), respectively, and at the same time, the pressing force of the first elastic body (151) and the pressing force of the second elastic body (152), which correspond to the pressing force of the finger, are transmitted to the sensor portion (110) and the vibrating portion (140), respectively, so that the sensor portion (110) and the vibrating portion (140) can be in close contact with the skin of the user's finger.

Accordingly, the vibration transmission efficiency of the vibration unit (140) to the user's finger is increased, and the pulse measurement accuracy and sensitivity, etc., when the sensor unit (110) measures the pulse of the blood vessels under the skin of the user's finger can be improved.

The wearable device of the present invention may further include a battery (170) formed in the internal space of the housing (160) and supplying electricity to the sensor unit (110), the communication unit (130), and the analysis unit (120). In addition, electricity may be supplied from the battery (170) to the vibrating unit (140). Such a battery (170) may be formed as a rechargeable type and may operate by supplying electricity to each of the above-described components.

The analysis unit (120) may be formed in the internal space of the housing (160) or on the outside of the housing (160). In FIG. 2, the analysis unit (120) is shown to be formed in the internal space of the housing (160), but the analysis unit (120) may also be formed on the outside of the housing (160). Specifically, the analysis unit (120) may be installed in an external electronic device such as a computer, a smartphone, a tablet PC, or a smartwatch to perform the same function.

Fig. 3 is a flow chart of a blood pressure measurement process of an analysis unit (120) according to an embodiment of the present invention, and Fig. 4 is a measurement graph by a photoplethysmography sensor according to an embodiment of the present invention. In Fig. 4, the horizontal axis is the number of detections and the vertical axis is a detection intensity value (dimensionless number compared to the maximum detection intensity value) by a photoplethysmography (PPG) sensor.

As shown in FIG. 3, in order to measure the user's blood pressure, the analysis unit (120) may perform a peak measurement step (S111) of measuring the time difference between the primary peak and the secondary peak that appear when measuring the pulse; a height selection step (S112) of selecting the user's height; an SI calculation step (S120) of calculating an SI value; and a blood pressure measurement step (S130) of deriving the user's blood pressure value using the SI value.

In order to perform the peak measurement step (S111) and the height selection step (S112), the analysis unit (120) can derive the vascular stiffness (Stiffness Index, SI) using the pulse wave information. Here, the vascular stiffness (SI) can be calculated by the following [Mathematical Formula 1].

[Mathematical Formula 1]

SI=h/ΔT

Here, SI is the vascular stiffness index (SI) value, h is the user's height, and ΔT is the time difference between the primary peak and the secondary peak that appear when measuring the user's pulse wave.

Information about the height of a user wearing the wearable device of the present invention may be stored in advance in the analysis unit (120), and the sensor unit (110) is equipped with a photoplethysmography (PPG: Photo-PlethysmoGraphy) sensor, so that, as shown in FIG. 4, the sensor unit (110) can continuously detect each of the primary peak and secondary peak of the pulse wave over time.

At this time, the pulse graph is a graph of a wave formed by multiple unit waves as one-cycle waves having one-cycle wavelength (λ), and each unit wave may have a first peak (a in Fig. 4) and a second peak (b in Fig. 4).

In addition, the photoplethysmography sensor of the sensor unit (110) can continuously detect the first and second peaks of the user's pulse by continuously detecting the pulse wave, and the analysis unit (120) can use this to calculate the vascular stiffness (SI) as described above, thereby calculating the vascular stiffness (SI) value over time.

And, the analysis unit (120) can derive the user's blood pressure value by using the user's blood vessel stiffness value by [Mathematical Formula 2] below.

[Mathematical formula 2]

BP=a*ln(SI)+b

Here, BP is blood pressure, SI is vascular stiffness, and a and b are each constants predetermined for each user. When a user of the wearable device of the present invention is determined, the SI value can be measured in advance using the wearable device of the present invention and the user's blood pressure can be measured using an external device, and the data on this can be input into the analysis unit (120). The analysis unit (120) can use this data to derive the a and b values of [Mathematical Formula 2], and store them as constants of [Mathematical Formula 2].

As described above, blood pressure can be measured in the analysis unit (120), and such blood pressure is derived by the SI value, and thus, the user's blood pressure fluctuations over time can also be derived according to the fluctuations in the SI value over time. Such blood pressure fluctuations can be measured as the mean arterial pressure (MAP) fluctuations below.

That is, by measuring the mean arterial pressure for multiple pulses in units of hours, the fluctuations thereof can be measured and utilized, and this is explained in more detail below.

Figures 5 to 7 are graphs for mean intraocular pressure, mean arterial pressure, and mean ocular perfusion pressure, respectively.

Here, FIG. 5 is a graph of the hourly mean intraocular pressure (IOP) measured during a given measurement time during a day for two patients (Patient 1, Patient 2), FIG. 6 is a graph of the hourly mean arterial pressure (MAP) measured during a given measurement time during a day for the two patients (Patient 1, Patient 2), and FIG. 7 is a graph of the hourly mean ocular perfusion pressure (MOPP) measured during a given measurement time during a day for the two patients (Patient 1, Patient 2).

In each of the graphs in FIGS. 5 to 7, the horizontal axis represents time, and the vertical axis represents mean intraocular pressure (IOP), mean arterial pressure (MAP), and mean ocular perfusion pressure (MOPP), respectively.

As shown in Figure 5, when comparing the graph of Patient 1 and the graph of Patient 2, it can be confirmed that the average intraocular pressure fluctuation (IOP fluctuation) value of Patient 1 is larger, and Patient 1 can be judged to have glaucoma symptoms. (In the case where the IOP fluctuation value exceeds 5, it is diagnosed as having glaucoma symptoms)

As shown in Figure 6, when comparing the graphs of Patient 1 and Patient 2, it can be seen that the mean arterial pressure fluctuation (MAP fluctuation) is formed during the corresponding measurement time, and similar to the occurrence of the fluctuation range of the mean intraocular pressure fluctuation (IOP fluctuation), the mean arterial pressure fluctuation (MAP fluctuation) of Patient 1 is larger. (Patient 1: 23.3, Patient 2: 11.3)

In this regard, in an experimental measurement of the relationship between computed blood pressure and intraocular pressure, it was confirmed that when systolic blood pressure increases by 10 mmHg, intraocular pressure increases by 0.24 mmHg, and when diastolic blood pressure increases by 10 mmHg, intraocular pressure increases by 0.4 mmHg, confirming the relationship (correlation: 0.94).

In addition, as shown in Fig. 7, when comparing the graph of Patient 1 and the graph of Patient 2, the graph of mean ocular perfusion pressure fluctuation (MOPP fluctuation) is formed similarly to the graph of mean arterial pressure fluctuation (MAP fluctuation), and similar to the occurrence of fluctuation range of mean intraocular pressure fluctuation (IOP fluctuation), it can be confirmed that the mean ocular perfusion pressure fluctuation (MOPP fluctuation) of Patient 1 is larger. (Patient 1: 27.3, Patient 2: 7.3)

As described above, it can be confirmed that the trend of the average intraocular pressure fluctuation (IOP fluctuation) value per patient is related to the trend of the average arterial pressure fluctuation (MAP fluctuation) value and the trend of the average ocular perfusion pressure fluctuation (MOPP fluctuation) value per patient.

That is, the user's blood pressure fluctuation affects the average intraocular pressure fluctuation (IOP fluctuation), and patients with severe average intraocular pressure fluctuation (IOP fluctuation) have a high incidence of glaucoma, i.e., can be diagnosed as having symptoms of glaucoma.

By the above principle, the analysis unit (120) can determine that the user has glaucoma if the average mean arterial pressure (MAP) fluctuation value of the user during the measurement period is greater than a predetermined value.

Specifically, the analysis unit (120) stores a reference fluctuation value, which is a fluctuation value of the mean arterial pressure that serves as a reference for a user wearing the wearable device of the present invention, and the analysis unit (120), which receives a signal from the sensor unit (110) as described above and derives the user's blood pressure fluctuation, can continuously measure the fluctuation value of the mean arterial pressure by hour, and if the analysis unit (120) analyzes that the user's fluctuation value of the mean arterial pressure exceeds the reference fluctuation value during the measurement of the fluctuation value of the mean arterial pressure by hour within a preset measurement period, the analysis unit (120) can determine that the user has glaucoma.

And, an operating signal is transmitted from the analysis unit (120) to the vibration unit (140), the vibration unit (140) operates, and the vibration of the vibration unit (140) is transmitted to the user's finger, so that the user can confirm that he or she has glaucoma.

A glaucoma monitoring system can be formed, including a wearable device of the present invention as described above, and a charger that is selectively combined with the wearable device of the present invention to perform charging.

As shown in (b) of Fig. 1, the charger may include a body (210) that wirelessly charges a battery (170) when adjacent to the wearable device of the present invention; and a holder (220) that is formed by protruding from the upper surface of the body (210) and into which the wearable device of the present invention is fitted.

In addition, a terminal (211) connected to a power cable and receiving electricity from a power source may be formed on the body (210), and an indicator (221) may be formed on the upper surface of the holder (220) to indicate with light whether the battery (170) is being charged, whether the battery (170) is fully charged, etc. (each distinguished by color).

In addition, the glaucoma monitoring system may further include a central processing unit formed outside the wearable device of the present invention to receive information from a plurality of wearable devices and perform collection and analysis of the information.

The central processing unit can use information from multiple wearable devices to classify users into each patient group, and perform analysis on trends in mean arterial pressure fluctuation (MAP fluctuation), mean intraocular pressure fluctuation (IOP fluctuation), and mean ocular perfusion pressure fluctuation in each patient group, and use patient diagnosis data according to IOP input into the central processing unit to derive the above-mentioned reference fluctuation value that serves as a diagnostic criterion in each patient group.

Here, in order to classify patient groups, patient information such as male and female gender, patient age, patient height and weight, etc. can be used. The central processing unit can also receive information on the wearing user from the analysis unit (120), and if the user belongs to a certain patient group, selects a standard change value suitable for the patient group and transmits it to the analysis unit (120), and the analysis unit (120) can perform the above analysis judgment using the standard change value.

When using the wearable device of the present invention as described above, the mean arterial pressure fluctuation (MAP fluctuation) is derived by measuring the user's pulse, and whether the user has glaucoma is determined based on this MAP fluctuation information, so that the measurement is quick and at the same time, the onset of glaucoma can be easily determined and analyzed.

In addition, when using the wearable device of the present invention, the wearable device of the present invention is always worn on the user's finger, and pulse measurement, etc. is performed in real time, and continuous analysis of disease occurrence is performed, so that the accuracy and speed of disease diagnosis, etc. can be improved.

Hereinafter, a method for monitoring glaucoma symptoms using the wearable device of the present invention will be described.

First, in the first step, the sensor unit (110) can detect the user's pulse wave. Then, in the second step, the pulse wave information is transmitted from the sensor unit (110) to the analysis unit (120), and the analysis unit (120) can derive the blood vessel stiffness (Stiffness Index, SI) using the pulse wave information.

Next, in the third step, the analysis unit (120) can derive the user's blood pressure value using the user's vascular stiffness value, and derive the user's average mean arterial pressure (MAP) value by hour within the measurement period. Then, in the fourth step, the analysis unit (120) can determine that the user has glaucoma if the user's average arterial pressure fluctuation value is greater than a predetermined value.

The remaining details of the glaucoma monitoring method of the present invention are the same as those described for the wearable device of the present invention described above.

The above description of the present invention is for illustrative purposes, and those skilled in the art will understand that the present invention can be easily modified into other specific forms without changing the technical idea or essential features of the present invention. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive.
