Pulse diagnosis instrument based on piezoresistive sensor array

Abstract

The invention relates to a pulse diagnosis instrument based on a piezoresistive sensor array, and belongs to the technical field of electronic equipment. The pulse diagnosis instrument structurally comprises a single chip microcomputer (1), a display screen module (2), a press key input module (3), a serial port communication module (4), a pressure sensor module (5), a waveform acquisition module(6), a high-fidelity signal conversion circuit (7), a noise inhibition circuit (8), a first analog-to-digital converter (9), a temperature sensor (10), a temperature compensation circuit (11), a second analog-to-digital converter (12), and a wrist band (13). The pulse diagnosis instrument has the advantages that the measuring accuracy is high, the anti-interference ability is strong, the influenceby environment temperature is little, and the like; the measuring result is conveniently transmitted to a computer, and the convenient expanding space is provided for remote medical therapy.

Description

technical field [0001] The invention belongs to the technical field of electronic equipment, in particular to a pulse diagnostic instrument based on piezoresistive sensor arrays. Background technique [0002] With the rapid development of today's society, people's life and work pace are very fast, which makes people's life more and more stressful, and the body is easy to enter sub-health or disease state. In terms of health preservation, traditional Chinese medicine has many effective methods for the body in a sub-healthy state. Traditional Chinese medicine has a long history and is unique in the world. Pulse diagnosis is an important link in the "four diagnostics" of traditional Chinese medicine: looking, smelling, asking, and feeling. It is one of the essences of Chinese medicine and a manifestation of the basic principle of TCM diagnosis. Traditional Chinese medicine believes that when qi and blood in the viscera of the human body become diseased, the blood circulation ...
