example

[0036] A wearable pulse wave detection system includes a glove body 1 and an inflatable and deflated airbag 11. In this embodiment, the tester wears the glove and fixes it with a wrist strap so that the flexible PCB used for measurement is directly Contact with the skin surface to obtain the biological signal of the human body.

[0037] refer to figure 2 , the structure of the flexible PCB 13 is designed to be 68mm in length, 35mm in width, and 0.15mm in thickness, and the MEMS pressure sensor array is a 3*3 array, which can place nine identical XGZU2009 MEMS pressure sensor chips and a DCM05 blood oxygen detection chip as well as an ADXL345 accelerometer.

[0038] The MEMS pressure sensor chip placed in the middle of the flexible PCB can detect the size of the pressure pulse wave on the skin surface through direct contact with the three places of the wrist, Guan and Chi.

[0039] The placed DCM05 blood oxygen detection chip detects the volume pulse wave in the blood vessel...

Abstract

The invention discloses a wearable pulse wave detection system. The system comprises a glove body, a pulse wave detection unit which is arranged on the inner side of the wrist of the glove body and used for detecting wrist pulse waves, a control and signal processing unit which is connected with the pulse wave detection unit, a glove wrist strap connected to the wrist of the glove body, an inflatable air bag and a micro air pump, wherein the inflatable air bag is arranged on the glove wrist strap, and the micro air pump is connected with the air bag. The inflatable air bag is arranged so thatthe contact pressure of the wrist portion of the glove body on the surface of wrist skin can be changed by controlling inflation and deflation of the air bag through the micro air pump, and then the pulse wave detection unit detects and obtains pulse waves under different contact pressures. The wearable device can be used for conveniently, continuously and reliably detect the pulse waves of a wearer.

Description

technical field [0001] The invention relates to the field of medical wearable devices, in particular to a wearable pulse wave detection system. Background technique [0002] As a key diagnostic technique in traditional Chinese medicine, pulse diagnosis has a very long history and unique creativity. With the development of the field of sensor monitoring, the quantification and objectification of pulse diagnosis has become a major goal of pulse diagnosis in traditional Chinese medicine. The physiological and pathological information of the human body included in the pulse wave has always been valued by Chinese and foreign medical circles as the basis for clinical diagnosis and treatment. The comprehensive information of the form (waveform), intensity (amplitude), velocity (wave velocity) and rhythm (period) presented by the pulse wave reflects many physiological and pathological characteristics of the human cardiovascular system to a large extent. [0003] Recently, research...
