Description

technical field [0001] The invention relates to the technical field of pulse condition information collection in traditional Chinese medicine, in particular to a multi-sensor-based pulse condition signal collection device and method capable of automatic pressure regulation. Background technique [0002] In TCM theory, the diagnosis and treatment of diseases are mostly based on pulse diagnosis because the pulse condition is the comprehensive result of the coordination and balance of various physiological functions, and it carries a wealth of information about human health. However, the traditional pulse diagnosis only relies on the doctor's fingers to distinguish the characteristics of the pulse condition, which is limited by sensation, experience and expression, and there are inevitably many subjective factors, which have a great impact on the standardization of pulse condition judgment. Therefore, using modern science and technology to objectively reproduce the pulse wavefo...

Problems solved by technology

[0004] Although the above-mentioned pulse condition instruments have described and analyzed the pulse condition signals to varying degrees, most of these pulse condition acquisition instruments are based on single-probe pressure sensors, which can only detect the pulse condition information of a certain part of inch, close and ruler, and mainly It mainly focuses on detecting the stable pulse condition of the "guan part". It simplifies and touches the multi-dimensional information fine receptors on the doctor's fingertips and replaces them with a touch point, which cannot fully reflect the information characteristics expressing the pulse condition of traditional Chinese medicine. There is still a certain gap in the method of cutting the pulse of "Jiuhou"

In addition, although there are reports on multi-probe and multiple pulse monitors, most of the sensor fixing methods are strap-type, which is likely to cause excessive deformation of the soft tissue around the sampling point and cause measurement errors, and has not been used in real clinical practice.

No matter which of the above-mentioned pulse conditioners is used to collect the pulse signal, it cannot simulate the actual "three parts and nine masters" pulse cutting method of traditional Chinese medicine, so as to ensure that the pulse condition can be extracted under the best pulse cutting force

[0005] The methods commonly used for pulse signal filtering include Fourier transform, wavelet transform, time-frequency analysis, etc., all of which include integral operations with fixed basis functions, and are limited by the uncertainty principle
