But it stops.

In addition, since the existing health management system only measures a bio-signal and notifies the result value, the effect is not greatly effective when the user does not have specialized knowledge. For example, the existing health management system can provide the user with a simple measured biometric signal in the form of a numerical or graph, but does not clearly transmit the current health status or the health status according to the measured biometric signal to the user. As a result, the user cannot clearly check the current state of health, and cannot recognize the problem of the current state of health and how to solve the problem. Only provides.

Meanwhile, in recent years, as mobile communication technology has rapidly developed, the function of a portable terminal has evolved from a simple call function to a multimedia phone with various functions as well as data communication.

As an example, technology to provide health-related services using a mobile terminal (e.g., a mobile phone) has been gradually developed, and a vibration sensor unit and a low frequency sensing unit are provided in the mobile phone to detect the number of steps and heart rate of the user, and then through a communication network. A technology that transmits to a server and analyzes the server to provide individual health-related information is disclosed.

However, these conventional health-related service provision technologies detect only a small part of the user's biometric information and provide health-related information, so that the health-related information is not accurate, and a misjudgment occurs. It can lead to incorrect dispatch, and there is a problem that the content of the service is extremely limited.

In addition, the conventional technology for providing health-related services has a problem in that 24-hour management is impossible, the patient cannot adequately respond to an emergency situation, and the surrounding safety information and expected emergency situation cannot be obtained accurately and quickly in advance.

Hereinafter, a method for providing personalized vital signs information and a system for providing personalized vital signs based on personalized bio-signals/peripheral data according to a preferred embodiment of the present invention will be described in detail.

First, a method for providing personalized vital sign information based on personalized bio-signal/peripheral data according to the present invention will be described with reference to FIG. 1. 1 is a flowchart showing a process of providing personalized vital sign information based on personalized biosignal/peripheral data according to the present invention.

The method for providing personalized vital sign information based on personalized bio-signal/peripheral data according to the present invention is a method for detecting a user's (life) vital sign and providing information in a predetermined format, as shown in FIG. , A data factor detection step (S100) of detecting a data factor for determining vital signs from a wearable device worn by a user; A data filtering step (S200) of filtering unnecessary data as abnormal symptom data among the data factors detected in the data factor detection step (S100); An abnormal symptom determination step (S300) of determining whether an abnormality has occurred in the vital sign based on the data filtered in the data filtering step (S200); And a notification determining step (S400) of determining whether to notify a user or a linkage notification based on the determination result in the abnormal symptom determination step (S300).

The data factor detected in the data factor detection step S100 includes a biosignal factor and a user environment factor. The biosignal factors include heart rate, respiratory rate, oxygen saturation, skin humidity, and daily walking amount, and the environmental factors surrounding the user include ambient temperature and ambient altitude.

The biosignal factor and the user's surrounding environment factor can be obtained by a sensing module(s) of a corresponding known technology.

For example, the heart rate, oxygen saturation, and respiration rate of the biosignal factor may be detected through a sensor configured in a wearable device (for example, a photo-plethysmography (PPG) sensor), and skin humidity ( Skin moisture) can be detected by a skin electrical resistance humidity sensor configured in a wearable device (e.g., a sensor that detects human body resistance according to the moisture and sweat component of the skin using the characteristic of linearly changing output according to resistance). I can. In addition, the daily walking amount is calculated as the average of Max-Min of the data by using the periodic characteristics in the Z-axis direction that occur during walking based on the data collected through the acceleration sensor.

In addition, sleep efficiency may be further included as the biosignal factor. Sleep efficiency can be obtained by Mosen sensor. Specifically, the average sleep cycle is set to 90 minutes, and 5 cycles per day and 7.5 hours of sleep are set as the standard for proper sleep. In general, REM sleep goes through Stage 1 and Stage 2, which are called shallow sleep, to recover the body at Stage 3 and Stage 4, and then goes to REM sleep after Stage 2. If there is movement of the body within the sleep cycle, the brain goes through the process of repeating from Stage 1 to resume REM sleep. Body movement, an element that affects sleep, is detected from the motion sensor, and sleep efficiency is obtained through the following equation.

Sleep Efficiency = Total Time Asleep (Total RAM Sleep Time) / Total Sleep Time (Total Sleep Time)

Subsequently, the ambient temperature and the ambient altitude of the user surrounding environment factor may be detected by a temperature sensor and an altitude sensor (or barometer sensor) configured in the wearable device, respectively.

Next, in the data filtering step (S200), when the heart rate is less than 60 or more than 130 seconds, the respiratory rate is less than 12 or more than 20, and the oxygen saturation level is less than 94 or more than 100, the data is treated as an exception. In other words, it is excluded as data to determine abnormal symptoms, and the data when the ambient temperature is 30℃ or higher or -12℃ or lower among the environmental factors of the user is treated as an exception, that is, excluded as data for determining abnormal symptoms. Includes processing.

Next, in the abnormal symptom determination step (S300), it is determined whether it is normal according to a biosignal factor and whether it is normal according to a user's surrounding environment factor based on the filtered data.

First, whether or not the heart rate, respiration rate, and oxygen saturation are normal according to the biosignal factor is determined.

Specifically, the determination of whether the heart rate is normal in the present invention is, under the condition that the respiratory rate and oxygen saturation as described below are determined to be normal, the heart rate exceeding 130 is less than 2 minutes or the heart rate is less than 60 2 minutes after the start of heart rate measurement. If it is less than, it is determined as normal, and if the heart rate exceeds 130 lasts for more than 2 minutes, or if the heart rate lasts for more than 2 minutes, it is determined as abnormal.

In addition, the determination of whether the respiratory rate is normal is when the heart rate and oxygen saturation are determined to be normal, the respiratory rate is less than 2 minutes after the start of the respiratory rate measurement, or the respiratory rate is less than 2 minutes, or the respiratory rate is 20. It is judged as normal when the excess occurs for 2 minutes or more and the movement is moving at a speed greater than running, and if the respiratory rate exceeds 20 lasts for more than 2 minutes or the respiratory rate is less than 12 for 2 minutes or more after the start of the respiratory rate measurement. It is judged as.

In addition, the determination of whether the oxygen saturation is normal is when the oxygen saturation is greater than 100 and less than 2 minutes, or the oxygen saturation is less than 94 and less than 2 minutes, or when the oxygen saturation is less than 94 and is more than 2 minutes and the movement is faster than running. When moving (moving at an abnormal speed within a preset range), it is determined as normal, and when an oxygen saturation exceeds 100 lasts for 2 minutes or more or an oxygen saturation exceeds 94 lasts for 2 minutes or more, it is determined as abnormal.

Next, as a determination of whether it is normal according to the user's surrounding environment factor, it is determined as normal if the ambient temperature is less than 2 minutes or the ambient temperature is less than 2 minutes after the measurement of the ambient temperature starts. If the ambient temperature lasts 30 degrees or more for 2 minutes or more after starting the measurement, or the ambient temperature continues for 2 minutes or more, it is judged as abnormal.

Next, the notification determination step (S400) of determining whether to notify the user or linkage notification based on the determination result in the abnormal symptom determination step (S300) includes a notification of the user himself/herself and a related acquaintance or organization. 2 to 5 are individual notifications according to heart rate, living environment temperature, respiratory rate, and oxygen saturation in the notification determination step included in the method for providing personalized vital signs information based on personalized bio-signal/peripheral data according to the present invention. It is a process diagram showing an example of a process.

In the notification determining step (S400), the user's own notification is basically determined as abnormal in heart rate, living environment temperature, respiratory rate, and oxygen saturation in the above-described abnormal symptom determination step (S300), the display unit of the wearable device or the wearable. This is a user terminal device such as a smartphone with an interlocking application that is linked by short-range communication with the device. Each heart rate is high and low and a rest message, the living environment temperature is low (cold) and high (hot) and a rest message, and the number of breaths is high and low and rest. A message, high or low oxygen saturation and suspicious messages will be displayed.

These are diagrams showing examples of implementation lists, scenarios, situation notifications, and notification messages.

In the notification determining step (S400), the related acquaintance or organization notification is a result of the determination of the motion sensor and the gravitational acceleration change value, heart rate, respiratory rate, oxygen saturation, etc., and when it is determined that it is an emergency or an emergency situation, the related acquaintance or association Rescue request text and/or calls to the agency 119 can be automatically executed.

Meanwhile, a system for providing personalized vital sign information based on personalized biosignal/peripheral data according to the present invention will be described with reference to FIGS. 14 to 17. 14 is a diagram schematically showing the configuration of a system for providing personalized vital sign information based on personalized bio-signal/peripheral data according to the present invention, and FIG. 15 is a diagram schematically showing the configuration of a personalized bio-signal/peripheral data-based system according to the present invention.

Next, the detection means may be composed of sensors capable of detecting a biosignal factor and a user surrounding environment factor. The biosignal factors include heart rate, respiratory rate, oxygen saturation, skin humidity, and daily walking amount, and the environmental factors surrounding the user include ambient temperature and ambient altitude. In particular, by including the surrounding altitude as a factor of the surrounding environment, it is possible to accurately determine whether the head moves severely or falls in connection with the biosignal factor.

Specifically, the detection means is a photo-plethysmography (PPG) sensor 210 configured in the wearable device 100 to detect the heart rate, oxygen saturation, and respiratory rate of the biosignal factor, and skin humidity (skin Skin electrical resistance humidity sensor to detect moisture (e.g., a sensor that detects human resistance according to the moisture and sweat component of the skin by using the characteristic that the output changes linearly depending on the resistance) 220, which occurs when walking And an acceleration sensor 230 that detects the amount of walking (number of steps) as an average of Max-Min of data using periodic characteristics in the Z-axis direction, and a motion sensor or gyro sensor 240 that detects motion.

In addition, sleep efficiency may be further included as a biosignal factor through the motion factor 240 as the biofactor factor. Specifically, sleep efficiency is based on an average sleep cycle of 90 minutes, 5 cycles per day, and 7.5 hours of sleep as a standard for proper sleep. In general, REM sleep goes through Stage 1 and Stage 2, which are called shallow sleep, to recover the body at Stage 3 and Stage 4, and then goes to REM sleep after Stage 2. If there is movement of the body within the sleep cycle, the brain goes through a process that repeats from Stage 1 to resume REM sleep. Body movement, an element that affects sleep, is detected from the motion sensor, and sleep efficiency is obtained through the following equation.
