Pulse signal collection device and method imitating pulse diagnosis techniques of traditional Chinese medicine

Abstract

The invention discloses a pulse signal collection device and method imitating pulse diagnosis techniques of traditional Chinese medicine. The collection device comprises a wrist carrier, a position adjusting mechanism, penetration shaft motors, a transmission mechanism, pulse sensors, a signal pre-processing circuit, a single-chip microcomputer and a computer. According to the pulse signal collection device and method, a method that the guan-position pulse sensor is positioned in the first place and then the cun-position sensor and the chi-position sensor are positioned is adopted, the finger distribution technique of pulse diagnosis of traditional Chinese medicine is imitated completely, and the pulse sensors of three positions, namely the cun position, the guan position and the chi position, are positioned at the same time more easily and more accurately. Through pulse signal amplitude values, the effectiveness of pulse signal collection is judged, thereby pulse signal collection can be started and ended automatically, and human intervention is not needed. On the basis of accurate positioning, the penetration shaft motors are controlled one by one through a control algorithm, the pressing depths of the pulse sensors at the cun position, the guan position and the chi position are adjusted in sequence, the pulse diagnosis technique of 'finger-finger alternation' is achieved, and the pulse feeling technique of 'three divisions and nine sub-divisions' of pulse diagnosis of traditional Chinese medicine is imitated completely.

Description

technical field [0001] The invention relates to the technical field of TCM pulse information collection, in particular to a pulse signal collection device and method imitating the TCM pulse diagnosis technique. Background technique [0002] 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 Qiemai fingering method is based on the "three fingers together" lower finger Qiemai method. 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 are pressed down at the same time; observe the three parts under the same pressure. The similarity or difference of the pulse chart under certain conditions; if necessary, the method of "finger-finger alternation" is used to adjust the finger pressure, and the pulse is r...

Problems solved by technology

However, the device and method can only obtain the pulse signal under a single pressure, and there is still a certain gap with the pulse diagnosis method of "three parts and nine masters" in traditional Chinese medicine.

[0005] The above pulse monitors and patents have preliminarily realized pulse signal collection, but there is still a big gap between the collection method and the "three parts and nine masters" pulse cutting method of traditional Chinese medicine pulse diagnosis, so the collected pulse signal cannot correspond to the pulse condition of traditional Chinese medicine

In particular, the lack of pulse signals under multiple pressing pressures has lost important pulse wave information and cannot fully reflect changes in human physiological functions, making it difficult to achieve accurate diagnosis of diseases
