Study on the Optimum Pulse-Taking Pressure and Probe Film Material Parameters during the Pulse Image Condition Detection

Abstract:

Pulse image detecting device was applied to acquire radial dynamic pulse images. In this paper, we improved the probe structure of the pulse image detecting device with new film material. Four kinds of different thickness films, the different pulse-taking pressures and the different sealed chamber pressures were used to determine the optimum film. For different subjects, the pulse amplitude was extracted with the different pulse-taking pressures and different sealed cavity pressures. The experiment results had shown that the best pulse amplitude could be obtained with the film thickness for 0.504 mm, pulse-taking pressure for 3 N and the sealed cavity pressure for 120KPa. This work provided an important theoretical basis for the parameter choice of the pulse image detection device.
