A pulse signal acquisition device and method imitating traditional Chinese medicine pulse diagnosis technique

Abstract

The invention discloses a pulse signal acquisition device and method imitating the traditional Chinese medicine pulse diagnosis method. The acquisition device includes a wrist rest, a position adjustment mechanism, a through-axis motor, a transmission mechanism, a pulse sensor, a signal preprocessing circuit, a single-chip microcomputer and a computer; The method of locating the off-position pulse sensor first, and then locating the inch-position and scale-position sensors is adopted, which completely imitates the finger-distributing method of pulse diagnosis in traditional Chinese medicine, and it is easier and more accurate to locate the pulse sensors at the three positions of the inch, close, and ruler at the same time; The pulse signal amplitude judges the validity of the pulse signal collection, so that the pulse signal collection can be automatically started and ended without human intervention. On the basis of accurate positioning, the present invention controls the through-axis motors one by one through the control algorithm, sequentially adjusts the pressing depth of the pulse sensor at the three parts of Cun Guan Chi, realizes the pulse diagnosis technique of "alternating fingers and fingers", and completely simulates the pulse diagnosis of traditional Chinese medicine "Three Departments and Nine Marquises" technique of pulse detection.

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
