Description

{Non-Stop Guarantee Type Smart Patch}

The present invention relates to a seamless guarantee type smart patch, and more particularly, to a smart patch which improves the power supply structure of smart patches attached to the body to measure various body information, thereby preventing the operation from being stopped by continuous power supply, To the non-guaranteed security type smart patch.

Generally, Biomedical Signal refers to a signal used to extract information from a biological system. It is used to stimulate and control human nerves or hormones, input and output of physical quantity, neurotransmitter or information form And is a signal that reflects its nature and activity in the physiological process, a complex phenomenon involving mechanical, electrical, or biomechanical activity. These signals are various biological signals, including biochemical signals in the form of hormones and neurotransmitters, electrical signals in the form of potentials or currents, and physical signals in the form of pressure or temperature.

Biological signals composed of chemical signals, electrical signals, and physical signals as described above can be measured from outside through a measuring instrument. If the measurement is outside the reference range based on the measured values of the human body in a healthy state, Additional inspection may be carried out.

Therefore, it is used to predict, prevent, and monitor the prognosis after treatment of diseases by preliminary diagnosis of diseases by measurement of biological signals.

In order to measure such a biological signal, a user visits a hospital or a medical institution having an examination facility and performs a check based on measured values measured by a professional worker. Therefore, due to the inconvenience that a user has to visit, There is a problem that the patient is missed or ill.

In recent years, a telemedicine method has been developed and widely spread, in which a variety of measuring instruments are miniaturized and are easily handled, measurement values are transmitted according to the development of wireless communication, and various devices are operated wirelessly, have.

Since the physical signals in the biological signals can be measured by various sensors, various devices for detecting the biological signals in contact with the body have been developed. Recently, sensors that can measure various bio-signals such as ECG, body temperature, acceleration sensor (3-axis), Fluid Assessment, EMG, and EEG have been developed and used.

It is possible to measure arrhythmia, congestive heart failure, activity measurement, rehabilitation momentum measurement, respiration measurement, sleep measurement, and concentration measurement by these various bio-signal measurement, Monitoring service, prognosis of paraplegic rehabilitation training monitoring service, inmate vital monitoring service, learning concentration measurement and improvement training service, and sleep monitoring service. The field of monitoring prognosis after treatment has been expanded and the effectiveness of use has been increasing.

In addition, devices for measuring bio-signals are being developed in various forms capable of independently transmitting and receiving data by communication due to development of wireless communication technology.

Accordingly, a wearable device equipped with a cloth, a pair of glasses, and a watch to be worn on the body has been developed and is used to measure various bio-signals at the position where the wearer makes contact with the wearer.

However, since the wearable device is limited in contact with the wearer's body, the contact distance between the wearable device and the wearer's body is not constant, so that the measurement signal is changed according to the contact interval, there was.

Accordingly, a patch-type medical measurement device capable of performing measurement by various sensors in the state of being attached to the skin of the body has been developed.

The Smart Patch is a system that detects multiple biological signals attached to the human body for prediction, prevention and prognosis monitoring by pre-diagnosis to prevent various diseases, and transmits the measured signals, And is a device for securing data of the management service.

The smart patch described above is attached to the skin and measures various kinds of living body signals by the sensor, and it has to be made in a form which is light in weight, small in size, and improved in adhesion to the skin.

Accordingly, the battery supplying the smart patch has been developed to reduce the weight and to reduce the size in consideration of the characteristics of the patch attached to the body. However, since the power capacity is reduced due to the weight reduction and the miniaturization, .

In addition, when the battery is replaced, power supply to the smart patch is interrupted and the measurement of the living body signal is stopped. Therefore, the monitoring is stopped and the user can not detect the emergency even if an emergency occurs.

In addition, when the measurement of the vital sign is resumed after the replacement of the battery, if the measured value is different from the measured value before the replacement, the reason why the measurement is changed during the stopped period can not be found.

Accordingly, it is urgently required to develop a device capable of ensuring the reliability of a biological signal measured by continuously supplying power without interruption while continuously replacing the battery without interruption of power supply of the smart patch.
