Study on Sensor Pressure Dependence of Pulse Waves

Pulse diagnosis is one of four efficient diagnostic methods in traditional Chinese medicine. There are various views about distinguishing the pulse which have been handed down as qualitative expressions based on experience. Then pulse diagnosis cannot be used widely and immediately by every one; long experience is required before applying it to diagnosis. In this study, to standardize pulse diagnosis, the pulse is taken near the wrist radius using a condenser microphone. The change of pulse image for the depression pressure of the microphone is noted, and the traditional expression of the change of pulse image by “the float press, the middle press and the sink press” is examined. As a result, the guideline on depression pressure and systematic change of the pulse image is obtained.
