Description

Wristwatch type health monitoring system {Wristwatch-type health monitoring system}

The present invention relates to a wrist-type health care device, and in particular, cuff and other biomedical information (ecg, body fat, pulse rate, pulse pressure, oxygen saturation, respiratory rate, body temperature, movement, It is related to the integration of a sensor for measuring the amount of activity, etc.) into one terminal.

In general, while the social environment is changing rapidly, health care costs are increasing with increasing interest in health. In the US, 14% of GDP and 7% of GDP are spent as health care costs in Korea. It is becoming.

In the medical service field, due to the rapid development of IT technology, research and development in the mobile healthcare field based on the ubiquitous environment combining IT technology and medical field is emerging.

Although the expenditure of medical expenses is increasing and new medical services are being developed, patients who need emergency rescue and treatment often do not receive adequate medical services even though there are many emergency rescue systems.

At present, the increase of elderly population due to the rapid aging society, the increase of dual-generation households, the physical distance between families due to the nuclear family, the rapid increase in facilities where elderly and elderly people, such as postpartum care centers and silver towns, and the medical space due to the declining population of farming and fishing villages In case of an emergency, it was not possible to report it to the emergency medical institution or to perform first aid promptly.

For example, health conditions, such as hypertension patients and diabetics, that require long-term treatment should be monitored periodically.

Hypertension patients with very irregular blood pressure should be monitored at least several times a day for conditions such as blood pressure and pulse rate. If the blood pressure is very high or low, the drug for the symptom should be administered very quickly.

As such, monitoring and first aid needs to be applied to diabetics.

Even when you are out, small and light weight blood pressure monitor, diabetes meter, etc. have been developed and widely distributed so that you can monitor your health status such as pulse, respiratory rate, blood pressure and body temperature at any time and place. However, it is not used much because of the inconvenience of follow-up processing using the monitoring result.

In addition, a large number of lives are lost due to the implementation of an emergency medical system that can be viewed by medical personnel such as doctors in charge, or processed data can be viewed by related medical personnel and guardians in real time. There is.

Even though each emergency room has a separate emergency call device for the patient, it is difficult to cope when the patient is in a serious crisis where it is difficult to operate the emergency call device or when a crisis occurs in a place such as a toilet outside the hospital room.

Therefore, a technology has been disclosed for a health status management system that can effectively and appropriately respond to emergencies by remotely monitoring an individual's health status in real time.

In addition, such an example is disclosed in Korean Unexamined Patent Publication No. 2008-0013129 (February 13, 2008) and the like.

That is, in the above document, as shown in FIG. 1, the health care terminal device has a form that is easy to attach to the body of the service subscriber. Preferably, the health care terminal device is attached to a cuff or the like that can accurately detect the physical condition of the service subscriber. Easy bracelet, watch form.

And the health care terminal device is a communication module for transmitting the health care information detected by the health measurement module, RFID module for obtaining patient information in case of an emergency, the external display to monitor the status of the service subscriber The emergency call button for sending an emergency rescue request signal to the outside by a patient status monitor, a patient or a guardian next to the patient, and an emergency call buzzer for outputting an emergency signal from the terminal device itself when the service subscriber is in an emergency state. Suggesting.

However, in the technique disclosed in the above-described Korean Patent Application Publication No. 2008-0013129, etc., the information for detecting the change in the user's body is detected only the pulse and body temperature, other ECG, body fat, oxygen saturation, respiratory rate, body temperature, movement, activity amount There was a problem that can not accurately grasp the user's health status by not detecting the back.

An object of the present invention has been made to solve the above problems, cuff and other biomedical information for measuring blood pressure in measuring the user's health information (electrocardiogram, body fat, pulse rate, pulse pressure, oxygen saturation, respiratory rate, The sensor for measuring body temperature, movement, activity, etc.) is integrated into one portable terminal, and the portable terminal provides a wrist-type health care device worn on the wrist in the same type as a wrist watch.

According to the wrist-type health care device according to the present invention, according to a simple operation of the health care device worn on the wrist to obtain a variety of biological information (oxygen saturation, pulse rate, pulse pressure, body temperature, electrocardiogram, body fat, movement, activity amount, blood pressure) It can be effective.

In addition, according to the wrist-type health care device according to the present invention, there is an effect that can check the user's health from a long distance because the user is carrying.

In order to achieve the above object, a wrist-type health care apparatus according to the present invention is attached to a wrist of a user and measures a bio-information, and includes an air tube for pressurizing and depressurizing the wrist of the user, A cuff portion surrounding the wrist and a body portion integrally formed with the cuff portion, wherein the body portion includes a measuring plate portion having one or more measuring sensors in contact with the user's wrist to measure the biometric information. do.

In the electrocardiogram measurement, the electric potential generated by the heart appears throughout the body and body surface, so the electrical activity of the heart can be expressed as a vector amount, and its amplitude depends not only on time but also on its position.

Based on this theoretical basis, when measuring the action potential of the heart by attaching two electrodes on different isopotentials, the potential difference of the active electrode based on the time axis is represented by a predetermined graph.

In addition, while applying a current of a suitable carrier frequency (about 20KHz ~ 100KHz) while measuring the voltage at this time to calculate the impedance of the human body through this to measure the respiratory rate of the user.

In the body fat measurement, if a predetermined current (250 mA) is applied to the body using a bioelectrical resistance measurement method, the current flows using the body's moisture as a conductor, while the body fat component acts as a resistance to change the input voltage. It is a way to use.

The second electrocardiogram sensor unit 250a and 250b together with the first electrocardiogram sensor unit 210a and 210b shown in FIG. 3 measure electrocardiogram, respiratory rate and body fat, and process the electrocardiogram signal in a controller to obtain a heart rate. have.

Here, the heart rate detects an electrocardiogram waveform and filters the detected signal to count the heart rate.

The blood glucose measurement unit 150 includes a strip and a current sensor, and when the user drops blood on the strip and inserts the same into the current sensor, electrons generated by the reaction of glucose and enzyme on the strip are detected by the current sensor. The current sensor detects the current generated by the electrons transmitted from the strip between the two terminals, and transmits the detected signal to the display unit 130 by transmitting the output signal to the display unit 130 according to the relationship according to the current and voltage. Display.

The cuff portion 120 is fixed to the rear of the body portion 110, it is fixed to the user's wrist in a velcro type to reduce the user's blood pressure by the contraction and expansion by the air of the rubber tube provided in the cuff portion 120 Measured by an acoustic vibration sensor (not shown).
