Abstract:
The authors developed an innovative apparatus for analyzing pulse waves which uses a new type of pulse sensor. Based on the principles of Oriental medicine, this pulse wave machine takes measurements from the radial artery to determine the subject's state of health. Three sensors were used in place of the fingers to assess changes in the pulse wave pattern induced by reducing pressure in a cuff. A cuff with sliding components proved to be the most suitable in that it was less likely to be affected by the subject's movements. Using this type of cuff, the authors were able to observe the pulse-wave amplitude as cuff pressure was reduced after the blood flow had been stopped. The signal in each channel changed according to the degree of pressure reduction, and a characteristic pulse wave pattern was produced. This pattern enabled the authors to observe how the pulse behaved under each sensor and how the pulse wave changed. The authors were also able to observe and measure the condition velocity as the artery opened as well as assess the condition of the palmer arterial arch.
