Flexible array man-machine cooperation pulse diagnosis instrument

Abstract

The invention provides a flexible array man-machine collaborative pulse diagnosis instrument. The flexible array man-machine collaborative pulse diagnosis instrument comprises a pulse diagnosis sensor, a signal collection circuit and a display interface, wherein a pressure signal to be detected is sensed by the pulse diagnosis sensor and is converted into an electric signal, the electric signal is collected by the signal collection circuit and is input into the computer after analog-to-digital conversion, and a pressure detection result is displayed through the display interface in the upper computer software. According to the man-machine cooperation pulse diagnosis instrument, the pulse feeling process of a doctor is simulated to the maximum extent, different static pressure amplitudes are applied to the cun, guan and chi fingers with the hAccording to the intention of a force application person. Meanwhile, static pressure intensity distribution of the whole pulse region can be measured, and therefore the problems that a traditional pulse diagnosis instrument evenly applies pressure and is insufficient in spatial resolution are solved. Meanwhile, the force exerting person can feel the pulsation information of the tested person through fingers across the pulse diagnosis instrument, namely the pulsation information of the tested person can be obtained by the force exerting person and the sensor at the same time.

Description

technical field [0001] The invention relates to the technical field of pulse wave measurement, in particular to a flexible array man-machine collaborative pulse diagnosis instrument. Background technique [0002] As an important part of world medicine, traditional Chinese medicine has played a very important role in the treatment of COVID-19. In TCM, inspection, listening, questioning and palpation constitute the basic diagnostic methods. Palpation, also known as pulse diagnosis, is an essential part. like figure 1 As shown, in pulse diagnosis, doctors usually press their fingers on three specific acupoints (cun, guan, chi) on the wrist to feel the fluctuation characteristics caused by the radial artery. Analyze to achieve the purpose of diagnosing diseases. In the theory of Western medicine, the pulse signal comes from the baroreflex of the arteries, and usually has three clearly distinguishable peak waveforms. The frequency, rhythm, wave velocity and volume of the puls...

Problems solved by technology

However, because most of the pulse beats are deep in the skin, it is generally necessary to apply a large pressure (≈10kPa) to achieve pulse acquisition. Most of the reported sensors cannot maintain high sensitivity under such a high pressure value. In addition, if the entire wrist The wrap exerts pressure, which can cause backflow of blood in the veins, which do not respond to normal pressure

Therefore, many pulse diagnosis instruments directly apply pressure on three specific acupoints, but the pressure applied by this method is uniform and constant, which is different from the doctor using
