Research of pulse position based on gradient pressure method

Abstract

Pulse position is an important part of pulse diagnosis of traditional Chinese medicine. The standardization of pulse position is the key to the digitization of pulse diagnosis. A pulse wave detection method and pulse position determination method based on gradient pressure are presented. The relationship between the depth of radial artery and the best pulse-taking pressure is discussed by Doppler ultrasonic detection of radial artery.And the difference between the best pulse-taking pressure and pulse position is pointed out. The criteria for defining pulse position by slope index and square difference index are proposed and calculation method is given. The pulse wave of 4 diabetic patients was measured and slope index and square difference index were calculated. The results were in line with the clinical diagnosis of traditional Chinese medicine, and the feasibility and accuracy of pulse position definition were verified. It provides a way of thinking for the digitization of pulse diagnosis in the future.
