Study on the pressure methods of pulse detecting instrument

Nowadays during the device of pulse sensor,the pressure pulse sensor device is widely used.Traditional pressure pulse sensor device to forward stepwise pressurization pressure,this approach leads to rebound phenomenon,making the test instability,longer test time,increase the float in the sink so the difficulty of distinguishing veins.Research described in this article is subject to the same method to measure pressure were taken to reverse the method and the positive pressure pulse method for the comparative experiments,the pulse pressure method instrument preliminary study to explore the more reasonable pulse detection the pressure method.
