Multi-channel pulse signal detecting method and device capable of automatically regulating pressure

Abstract

The invention relates to a multi-channel pulse signal detecting method and device capable of automatically regulating pressure. The method comprises the following steps: 1) sticking wrist bands with a cun-pulse sensor, a guan-pulse sensor and a chi-pulse sensor on a wrist respectively; 2) collecting pulse signals under collecting pressures of light, medium and heavy, and transmitting the signals to a signal regulating circuit; 3) converting the pulse signals which are processed by the signal regulating circuit into digital signals, and storing the digital signals in a singlechip; and 4) transmitting the digital signals to a computer by the singlechip, displaying a real-time pulse signal curve by the computer, and performing pulse cycle identification and pulse characteristic extraction onthe pulse signal curve to complete the pulse signal detection. The device comprises the wrist bands, the cun-pulse sensor, the guan-pulse sensor, the chi-pulse sensor, a pressure sensor, the signal regulating circuit, an analog / digital (A / D) converter, the singlechip, the computer and a pressurizing module. Compared with the prior art, the device has the advantages of low power consumption, high pressure control accuracy, multi-pulse position integral representation and the like.

Description

technical field [0001] The invention relates to a method and a device for detecting a pulse signal, in particular to a method and a device for detecting a multi-channel pulse signal with automatic voltage regulation. Background technique [0002] The reason why pulse diagnosis is important is that the pulse condition can convey the physiological and pathological information of each part of the body, and it is a window to peep into the functional changes in the body, which can provide an important basis for diagnosing diseases. However, traditional pulse diagnosis mainly relies on the doctor's experience and subjective judgment, coupled with the individual differences of the patients, the identification and identification of pulse conditions lack uniform and accurate standards. Therefore, the development of the pulse acquisition system is helpful to the objective research of pulse diagnosis. The difficulty in the design of the pulse collection system lies in how to simulate ...

Another method is to use multi-probes to collect multiple pulse points at the same time. The disadvantage is that the pulse signals obtained are not stable enough and easily interfere with each other.

No matter what method is used to extract the pulse signal, the current acquisition method can only be collected under the same pulse-taking pressure, ignoring the three pulse-taking states of floating, middle and sinking described in traditional Chinese medicine.
