Wearable physical sign detector, physical sign telemetering and warning system and method

Abstract

The present invention is wearable physical sign detector, physical sign telemetering and warning system and method. The system includes a physical sign detector, an analysis and judgment base station and an emergency treatment device. The physical sign detector sends detected physical sign information to the analysis and judgment base station in radio or wired mode. In case of emergency, the analysis and judgment base station sends first-aid signal and the detected physical sign information to the emergency treatment device automatically in radio or wired mode. The present invention senses PPG signal from the ear of the wearer of the physical sign detector, and has raised comfort deg and decreased sports pseudo image interference. The present invention may join to automatic emergency alarm service system for sending emergency calling to the emergency aid center and transmitting physical sign information.

Description

technical field [0001] The present invention relates to a wearable physiological sign detector, physiological sign telemetry and alarm system and method, in particular to a wearable physiological sign detection which senses the PPG signal from the part behind the wearer's ear and calculates the pulse rate and oxygen saturation Detector, physiological sign telemetry and alarm system and method. Background technique [0002] As we all know, the world has entered the age of population aging. How to ensure that the elderly spend their old age safely is a special problem among many social problems. According to relevant experts and figures provided by medical and health care departments, sudden diseases have been on the rise among the elderly in recent years, and they are rapidly becoming younger. Taking Hong Kong as an example, there are one million elderly people over 60 years old, and 800,000 of them are over 65 years old. What deserves more attention is the sharp increase ...

Problems solved by technology

Sensing the electrocardiogram (ECG) signal of the chest of the monitoring object needs to attach electrodes to the chest. Since the ECG electrodes are attached to the chest skin, the affinity to the wearer is very poor; using photosensitive sensors (photoplethysmography, PPG), the reported sensitivity The sensor is located on finger clips, rings, earlobe clips, earplugs, and wristbands, and the pulse signal is sensed at the finger or wrist. Due to the frequent movement of fingers and wrists, the sensed PPG signal is susceptible to motion artifacts. In addition, to use this method to obtain reliable PPG signals at the above-mentioned parts, it is necessary to apply a certain pressure to the measurement part, which makes the monitoring object feel uncomfortable

There is also a use of the earlobe as a location point for transmitting pulse oximetry tests, however, the clamping device used to support the sensor above the earlobe is uncomfortable for the wearer to wear for a long time; An optical sensor inserted into the tract senses the PPG signal of the contacting tissue

However, the wearing comfort of this method is still not ideal.

[0006] These methods either require pressure to be applied to the sensing site, or the test results are not very reliable when the body is moving due to susceptibility to motion artifacts

On the other hand, traditional wearable physiological sign detectors do not monitor the wearer's exercise status or ability
