Abstract

The invention provides a pulse wave acquisition device and a pulse wave acquisition and calibration method. The pulse wave acquisition device is used for acquiring pulse waves when a human body pulse detection part is subjected to different outer pressures; the pulse wave acquisition device comprises a fixing band, a pressure adjustment part, a pulse sensor and a pressure transmission part, wherein the fixing band is wound at the human body pulse detection part; the pressure adjustment part is connected with the fixing band; the pulse sensor comprises a sensing thin film; the sensing thin film is connected with one end, far away from the fixing band, of the pressure adjustment part, so that the pressure adjustment part tightly presses the sensing thin film on the human body pulse detection part; the sensing thin film is used for converting the pulse waves into a piezoelectric signal, wherein the sensing thin film is made of a flexible material; the pressure adjustment part is connected with the sensing thin film through the pressure transmission part, so that an extruding force generated by the pressure adjustment part is uniformly transmitted to the surface of the sensing thin film. By adopting the pulse wave acquisition device and the pulse wave acquisition and calibration method, the problem of a pulse wave acquisition device in the prior art that pulse condition information of a human body cannot be accurately reflected is solved.

Description

technical field [0001] The invention relates to the technical field of pulse wave acquisition, in particular to a pulse wave acquisition device and a pulse wave acquisition calibration method. Background technique [0002] TCM pulse diagnosis has experienced more than 2,000 years of clinical practice, and is one of the essence of the four diagnostic methods of traditional Chinese medicine in my country. The theory of traditional Chinese medicine believes that when the qi and blood of the viscera of the human body are diseased, the blood circulation will be affected, and the pulse condition will change. The traditional fingering method for pulse diagnosis is based on the "three fingers together" method of pulse diagnosis with the lower finger. It is mainly to understand the characteristics of the pulse condition and the change of the pulse condition with the change of applied pressure when the three parts of "cun, guan and chi" are lowered at the same time; Observe the simil...
