Study on the pressure methods of pulse detecting instrument

Traditional pressure pulse sensor device is 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, 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.
