Description

Smart bio sensing system and smart bio sensing method using a wearable unit {SMART BIO SENSING SYSTEM AND SMART BIO SENSING METHOD USING THE WEARABLE UNIT}

The present invention relates to a smart bio-sensing system and a smart bio-sensing method using a wearable unit, and more specifically, a physical situation of a user wearing a wearable unit in real time in response to a state of close contact between the user's body and the biosensing unit. It relates to a smart bio-sensing system and a smart bio-sensing method using a wearable unit for monitoring.

In general, a blood pressure monitor by air pressure, which is mainly used in hospitals, measures blood pressure and pulse by applying pressure to the forearm while a person is stabilized to some extent. It is not recommended to measure more than 6 times a day. It cannot be carried and easily measured blood pressure. On the other hand, a smart blood pressure monitor that is free from a fixed type can be carried in its own way, but it is still large and inconvenient, and there are many productions such as power and size to use as a real-time wearable.

It introduces a technology to measure blood pressure using the time difference between the peak values of an electrocardiography (ECG) sensor or a photo plethysmography (PPG) sensor. This has a lot of difficulty in accurately measuring blood pressure because of various characteristics for each person.

First, an electrocardiogram sensor may be installed on the chest to measure blood pressure, or an optical pulse wave sensor may be installed on the forearm or wrist to measure blood pressure. That is, by placing two different sensors at a certain distance and analyzing a time difference for a physical response by an algorithm, blood pressure can be measured.

Second, the time interval of peak values of a pair of ECG sensors or a pair of optical pulse wave sensors having a certain distance may be measured by blood pressure. That is, by placing two identical sensors at a certain distance and analyzing a time difference for a physical response by an algorithm, blood pressure can be measured.

To measure blood pressure as in the prior art, it is quite complicated. In particular, at least two sensors should be attached to two places on the body with a certain distance apart, and blood pressure should be expressed by measuring the peak value of each sensor signal. In addition, for the actual measurement, the stabilization of the skin and the measurement electrode must be prioritized, and since the error increases according to the skin color or various noises, it is very difficult to accurately measure.

For example, by using the optical pulse wave sensor of the pressure sensing unit 120 and the bio sensing unit 150, it is possible to measure the physical condition of the user. In this case, the pressure sensing unit 120 may measure a constant contact pressure generated according to the contact state between the optical pulse wave sensor and the user's body, and the optical pulse wave sensor may measure a waveform that changes as blood passes through the blood vessel. Then, the sensing display app 200 analyzes the waveform of the optical pulse wave sensor for the pressure signal measured by the pressure sensing unit 120 to calculate at least one of blood pressure, pulse, blood flow, and oxygen saturation among the user's body conditions. I can. Since the waveform of the optical pulse wave sensor is analyzed in response to the pressure signal measured by the pressure sensing unit 120, the waveform of the optical pulse wave sensor can be increased, and accuracy for measuring the user's body condition can be improved. In particular, since the waveform is analyzed based on the pressure signal measured by the pressure sensing unit 120, measurement accuracy for at least one of blood pressure and pulse rate, blood flow, and oxygen saturation among the user's body conditions is improved.

As another example, the user's body condition may be measured by using the pressure sensors of the pressure sensing unit 120 and the bio sensing unit 150. At this time, the pressure sensing unit 120 may measure a constant contact pressure generated according to the contact state between the pressure sensor and the user's body, and the pressure sensor may measure the intensity of pressure reflected as blood passes through the blood vessel.

In this way, it is characterized by measuring the user's body condition using two pressure sensors. In other words, the blood pressure is measured by knowing the amount of a constant pressure from the outside, and the pressure of the blood vessel accordingly. In particular, since the pressure intensity is analyzed based on the pressure signal measured by the pressure sensing unit 120, the measurement accuracy of at least one of blood pressure, pulse, blood flow, and oxygen saturation among the user's body conditions is improved.

As another example, the user's body condition may be measured using only the pressure sensor of the biosensing unit 150. At this time, since an external force caused by the elastic force of the wearable unit W and the elastic force of the elastic pad unit 140 constantly presses the blood vessel at the installation position, a pressure signal through the pressure sensing unit 120 is not required. Without the sensing unit 120, the pressure sensor measures the pressure intensity reflected by the blood passing through the blood vessel, so that the sensing display app 200 analyzes the pressure intensity measured by the pressure sensor to determine the blood pressure, pulse, and blood flow in the user's body situation. At least one of and oxygen saturation can be calculated.

As another example, a user's body condition may be measured using temperature sensors of the pressure sensing unit 120 and the bio sensing unit 150. In this case, the pressure sensing unit 120 may measure the contact pressure generated according to the contact state between the pressure sensor and the user's body, and the temperature sensor may measure heat generated by the user's body. Then, the sensing display app 200 may calculate the body temperature of the user's body condition by analyzing the pressure signal measured by the pressure sensing unit 120 and the temperature signal measured by the temperature sensor. In particular, since the temperature signal is analyzed based on the pressure signal measured by the pressure sensing unit 120, the measurement accuracy of the body temperature in the user's body situation is improved.
