摘要
在目前用于检测中医脉象的传感器中,以压力型的脉象仪传感器应用最为广泛。传统的压力脉象传感器都采取正向逐步加压法加压,但经研究发现,这种方法会导致皮肤的回弹现象,使得测试不稳定,测试时间较长,同时增加了浮中沉等脉的判别难度。本文所介绍的研究方法是对相同受试者分别进行正向加压与反向减压测取脉象的方法作对比实验,通过观察两种方法对脉象信息的压力变化值、幅值参数以及时间参数的变化,比较两种方法对压力型脉象仪检测脉象信息的稳定性、准确性,试图探寻脉象检测中更合理的加压方法。
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.
