The present invention relates to a portable health signal measuring apparatus, and more particularly, to a portable health signal measuring device built in a predetermined position of a mobile communication terminal so that the user's current health state can be measured regardless of time and place. It relates to a signal measuring device.

With the aging of society, people's awareness of health care, health maintenance and health promotion is increasing, regardless of age group. Many people these days are not only diagnosed or advised by experts in medical facilities such as hospitals for the early detection or prevention of diseases, but also by using non-medical facilities such as sports clubs to manage, maintain, We are working to promote it. In addition, a number of devices have been developed to support home health care to monitor their health in the home or to continue treatment.

In professional medical facilities such as hospitals and clinics, various measurement devices for detecting biological signs are arranged in the facility, and the host computer (or a facility) of the biological information detected by these devices is provided through a local area network (LAN) or a telemeter. It is known to centrally manage medical data by transferring it to a workstation in a medical information management room (for example, Japanese Patent Application Laid-Open No. 2-140875, Japanese Patent Application Laid-open No. 2-116351, Japanese Patent Application Laid-Open No. 2-299632 (above, Japanese patent application). Published), European patent application 269,907 AI).

In order to detect biomedical information in these specialized medical institutions, people have to deliberately go to the medical institution every time they are not hospitalized, so they are given a lot of burden, especially for patients during the treatment of the disease. Entails. As a result, there is an unreasonable inability to measure the latest biometric information because the number of detections of the biometric information is inevitably limited (insufficient of the best information).

Another important problem of collecting biometric information in professional medical institutions is that the reliability of the obtained biometric information is not very high. That is, for example, in recording an electrocardiogram or measuring blood pressure, the patient often feels nervous and excited about the measurement, and thus the data obtained often shows an outlier and often needs to be measured again. Insufficient reliability as data).

In order to solve this problem, a technique for installing a biosignal detection apparatus in a patient's home and transmitting the obtained biometric information to a host computer of a professional medical institution through a public communication line is disclosed (for example, Japanese Patent Application Laid-Open No. 2). -54031, Japanese Patent Application Laid-Open No. 2-279056, Japanese Patent Application Laid-Open No. 2-121627 (above, published in Japanese Patent Application), US Patent 4,962,550, and European Patent Application 292,311 A1. For example, the home system disclosed in US Pat. No. 4,962,550 is configured to install a urine analysis device in connection with a toilet in the home and transmit the obtained urine analysis data to a remote computer. In addition, the international patent application WO / 91/05311 discloses a terminal device having a biometric information measuring function such as blood pressure in a patient's home, measuring blood pressure or the like in the home by an instruction from the central station, and then measuring data. A health care support system is disclosed in which a central station determines a medication administration and directs a patient based on the transmitted data.

These home systems have the advantage that the biological information can be obtained more frequently and the latest information can be obtained since measurements can be made at home. However, since these systems are designed to execute a series of measurement programs by operating the device while the user interacts with the computer or central station of the measurement device via a keyboard or other man-machine interface, Not only is this cumbersome, but the user needs to be actively involved in the operation in the measurement. In particular, elderly people are generally unfamiliar with the man machine interface, and since the response such as memory, visual acuity, muscles, and the like is insufficient, it is often difficult for the elderly to access the man machine interface.

On the other hand, in order to operate various home appliances used for health care, some kind of biometric information related to the user must be input in advance. For example, in using a home exercise equipment such as an ergometer, it is necessary to enter various types of parameters such as a user's height, weight, age, sex, body fat percentage and required exercise amount. In addition, in order to measure body fat percentage at home, it is preferable to input data such as height, weight, age, sex, and daily exercise amount. In addition, in order to use a diet builder composed of a database, it is necessary to input weight, urine analysis data, the amount of exercise of the day, and other biometric information. This kind of information is also cumbersome because the user has to enter it through a man-machine interface such as a keyboard.

In order to solve these problems, a health care network system has been introduced that can collect biometric information without consciousness of measurement to an individual with the user's daily activities. According to Korean Patent Publication No. 1993-17550 (name of the invention: a health care network system), various measuring devices are installed in a device used for daily activities of an individual, and the excretion, In addition to passively acquiring personal biometric information along with personal activities of daily living such as bathing, sleep, rest, and indoor exercise, the biometric information obtained is transmitted to a specialized institution through a network for management. In other words, the above-mentioned health care network system collects personal biometric information without consciousness of measurement by an individual with the activity of an individual's daily life, and is also suitable for an individual who has difficulty in manipulating a man-machine interface like an elderly person. It does not require the individual's active involvement through the machine interface, it can collect the biometric information passively with the daily activities of the individual, and go to the home or work without having to go to a specialized medical facility such as a hospital or clinic. It is possible to support health care (health care such as disease prevention, early detection, and continuation of treatment) in the living environment, which enables prevention and early detection of diseases, and personal health management, health maintenance, and health promotion. You can contribute to.

Therefore, the present invention has been devised in view of the above-described health care network system, and an object of the present invention is to carry a health signal for measuring biological information on a mobile communication terminal that can be carried anywhere and anytime, and is carried by most people. The built-in device provides a portable health signal measuring device capable of collecting biometric information of a user regardless of time and place and simultaneously transmitting biometric information to a desired place through a portable communication terminal.

It is self-evident to those of ordinary knowledge in Esau. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

First, with reference to Figure 1 will be described an embodiment of the application of the portable health signal measuring apparatus according to the present invention. As shown in FIG. 1, a health signal measuring apparatus 120 is installed on at least one or more buttons 101 of a function button or a number button of a mobile communication terminal 100 which a majority of users carry. It is preferable to configure the biometric information of the user to be detected in a state in which the user does not recognize the operation.

In addition, preferably, the health signal measuring apparatus 120 includes two wavelengths of light (for example, infrared and red light) generated from at least one light emitting unit 121 (for example, LED) installed adjacent to the button. It is configured to be reflected by a specific part of the human body (for example, a finger) of the user, and the reflected light is detected by the silicon type light detector 122 through a transparent film type button having transparency.

That is, as shown in FIG. 1, when the light detector 122 is made of a silicon material and a button 101 made of a transparent film (polyester) is formed thereon, the light emitted from the light emitting part 121 is emitted. The reflection from the human body is detected by the light detector 122, and the insulation problem between the human body and the health signal measuring apparatus 120 may be solved.

On the other hand, as shown in Figure 2, the light emitting unit 121 and the light detecting unit 122 is provided at the bottom of the case is composed of buttons of the mobile communication terminal 100, the light emitting unit 121 and the light detecting unit 122 The lower end of the health signal measuring unit 123 is installed, the health signal measuring unit 123 is connected to the main controller (not shown) of the mobile communication terminal 100 can transmit and receive data and signals to each other. .

In addition, referring to FIG. 3, a detailed configuration of the health signal measuring unit 123 is described. The driving signal generator 124 outputs a driving signal for controlling the light emission operation of the light emitting unit 121.

The amplifier 125 is responsible for amplifying the biological signal detected by the light detector 122 to a size suitable for signal processing, and the A / D converter 126 is amplified by the amplifier 125. The amplified analogue biosignal is converted into digital data capable of signal processing.

The signal processor 127 analyzes the digital data converted by the A / D converter 126 to determine the health state of the user, and notifies the determined result. The description of the state in which the health state of the user is grasped by the signal processor 127 will be described in more detail in the operation description below.

The interface unit 128 is portable to transmit the result measured by the health signal measuring unit 123 (that is, the biosignal measurement result) to a registered medical institution (hospital, health center, etc.) through the mobile communication terminal 100. It transmits to the main controller (not shown) of the communication terminal 100, and transmits a response received from a pre-registered medical institution to the following control device 129. That is, the measurement result of the health signal measuring unit 123 transmitted through the interface unit 128 is temporarily stored in the storage unit 130 described below, and the mobile communication terminal 100 uses its own wireless communication function. The measurement result is connected to the registered medical institution, and the measurement result is transmitted, and the response result transmitted from the medical institution is received and displayed on the display device (for example, LCD) of the mobile communication terminal 100.

The control device 129 controls the overall operating state of the health signal measuring unit 123. That is, the control device 129 controls the signal processing unit 127 to determine the health state through the previously collected bio-signals, and is portable to transmit the health state information to the pre-registered medical institution through the interface unit 128. It communicates with the main controller of the communication terminal 100, controls the driving signal generator 124 to determine the light emitting state of the light emitting unit 121, and displays health state information on the display device of the mobile communication terminal 100. To control it.

The storage unit 130 stores various programs for the controller 129 to measure and determine health information, and temporarily stores various data (biosignal data, health state information, etc.) generated by the health signal measuring unit 123. It is responsible for storing. In addition, the storage unit 130 stores the reference biosignal data serving as a reference for analyzing the biosignal data among various data generated by the health signal measuring unit 123 in a table form.

Referring to the operation according to an embodiment of the present invention having such a configuration as follows.

When the user switches the mobile communication terminal 100 carried by the user to a standby state (for example, a folder or flip is opened, and in the case of a slide phone, the upper part is slid), the various types of the mobile communication terminal 100 The buttons are made to emit light by the pre-installed light emitting unit. Here, the light emitting unit pre-installed on the various buttons of the mobile communication terminal 100 when the user opens a folder (or flip, etc.) of the mobile communication terminal 100, the light emitting state is released after a certain time, the light is no longer irradiated Although not configured, the light emitting unit 121 for measuring the bio-signal applied to the present invention is preferably configured to maintain a constant light emitting state.

In this case, when the user touches a specific part (eg, a finger) of the body to a button on which the health signal measuring unit 123 is installed among various buttons of the mobile communication terminal 100, the light emitting unit 121 generates the light. Light is reflected by the body to reach the light detector 122.

The reflected light reaching the photo detector 122 is converted into an electrical signal by the photo detector 122, and a high frequency component, which is a noise component, is removed through a high frequency filter in the photo detector 122, and a DC component is removed using a low frequency filter. At the same time, the average value filter is used to improve the signal-to-noise ratio, and then amplified to a size suitable for signal processing by the amplifier 125, and then converted into a digital signal by the A / D converter 126. .

The signal processor 127 calculates a desired biosignal, for example, pulse, respiration, blood flow, oxygen saturation, stress state, and body fat value through comparative analysis of wavelengths of a digital signal, and calculates the calculated value. The measurement result (ie, health state information) of the biosignal is calculated based on the result of the comparison with the value of the reference biosignal table stored in the storage 130. That is, for example, when the blood flows along the blood vessel, the light irradiated from the light emitting unit 121 is diffusely reflected by the blood. At this time, the light is diffusely reflected according to the movement of the blood and detected by the light detector 122 It has a pulsating signal of a certain frequency band. Therefore, when the pulsation signal of the corresponding frequency band is detected and the peak component is analyzed, the number of pulses can be measured.

In addition, as the user breathes, blood vessels expand in inhalation and blood vessels contract in exhalation, thereby changing the amount of blood that moves. At this time, the light diffusely reflected according to the amount of blood movement and detected by the light detector 122 has a pulsation signal of a predetermined frequency band slightly different from that of the pulse. Therefore, the number of breaths can be measured by analyzing the peak component by detecting the pulsation signal of the corresponding frequency band.

The analysis method of the bio-signal by the signal processor 127 is described in detail in Korean Patent Application No. 2001-21124 and Korean Patent Publication No. 2003-75225. Therefore, in the present invention, the conventional biosignal analysis method is applied and used, and thus, the technical idea of the present invention is not limited to providing a biosignal measurement and analysis device which is easy to carry, but a biosignal analysis method. I want to clarify.

The biosignal measurement result calculated by the signal processor 127 is transmitted to the control device 129, and the control device 129 stores the biosignal measurement result in the storage unit 130 and at the same time the portable communication terminal 100. In communication with the main controller of the display on the display device of the mobile communication terminal (100). In addition, the control device 129 communicates with the main controller of the mobile communication terminal 100 through the interface unit 128, and requests to transmit the biosignal measurement result to a registered medical institution as necessary. Accordingly, the main controller of the mobile communication terminal 100 transmits a biosignal measurement result transmitted from the control device 129 of the health signal measuring unit 123 to a registered medical institution. In addition, the main controller of the mobile communication terminal 100 receives a response from a registered medical institution and displays it on the display device. Accordingly, the user can visually confirm the prescription from the medical institution.

On the other hand, in the present invention, when the user switches the mobile communication terminal 100 carried by the user to the standby state (for example, a folder or flip open state, in the case of a slide phone, the upper sliding state), the mobile communication terminal Buttons of the various buttons of the 100 are made to emit light by the pre-installed light emitting unit. Here, the light emitting unit pre-installed on the various buttons of the mobile communication terminal 100, the user is opened a folder (or flip, etc.) of the mobile communication terminal 100, when a predetermined time elapses, the light emission state is released and the light is no longer irradiated Although the light emitting unit 121 for measuring the bio-signal applied to the present invention is maintained in an idling state, the light reflected by the user connecting a part of the body to a button on which the light emitting unit 121 is installed It may be configured to switch back to the light emitting state when the predetermined level or more, that is, when the intensity of the light detected by the light detector 122 is above the predetermined level.

In addition, in the present invention, a button having a health signal measuring function may be separately configured on the mobile communication terminal 100 so that the light emitting unit 121 emits light when the user presses the health signal measuring button. In addition to the health signal measurement function in the basic menu of 100 may be configured so that the light emitting unit 121 emits light as the user selects the health signal measurement function.

Meanwhile, in the present invention, the health signal measuring unit 123 may be implemented as a single chip using a digital logic technology such as a field programmable gate array (FPGA). In this case, since the size of the health signal measuring unit 123 can be downsized to a size of several tens of mm2 and power consumption can be minimized (㎽, ㎼, etc.), it is possible to install the portable communication terminal 100. . Since the chip contains various functional components, it must be able to handle mixed signals. For this, it is appropriate to use a CMOS process of 0.15 to 0.3㎛. In other words, the process of designing and fabricating the chip using the design parameters suitable for the process through chip synthesis, circuit synthesis, etc., and comparing it with higher-level simulation results using timing simulation and circuit simulation such as HSPICE. Will go through.

As described above, in the detailed description of the present invention, specific embodiments have been described. However, various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the claims below but also by the equivalents of the claims.

Do.

In addition, it is convenient because it detects the user's bio-signal using the light generated by the light emitting unit, and there is no user's rejection compared to the blood collection method.

In addition, every time the user connects the body to the button of the mobile communication terminal detects the bio-signal, it is possible to obtain continuous data, it is possible to provide important data for health care.

In addition, by using a wireless communication function, which is a unique function of the mobile communication terminal, the biosignal is transmitted to the medical institution and the response is received from the medical institution, thereby eliminating the need for a separate communication additional device.
