We measure signals off a radial arterial pulse by using a prototype clamping pulsimeter equipped with a Hall device, which produces signals through a voltage-detecting circuit. The two important measuring times of the systolic peak time and the reflective peak time for a temporally pulsed signal are analyzed for an arbitrary, pulsed wave at one position of a small permanent magnet. The measured value of the PPWV (peripheral pulse wave velocity) is about 1.25 m/s. Thus, this method is proven to be one new method to measure an exact value of the pulse wave velocity. To measure the PBV (peripheral blood velocity), the we simultaneously connect the radial artery pulsimeter to a PPG (photoplethysmography). The average value of the PBV is about 0.46 m/s. The prediction of the blood vessel's property from an analysis of the PPBV may be useful for developing an Oriental-Western diagnostic medical signal device for a U-health-care system in the future.
