摘要
穴位是人体经络脏腑之气血输注的部位,体内气血的变化可反应于相应的穴位,尚可表现为相应穴位电学特性的改变。设计了一种基于采集卡PCI8335B控制并采集信号,主要由AD9833,AD620,AD8302等组成的硬件系统,通过VB语言编写PCI8335B的控制信号并采集硬件产生的穴位阻抗电信号,实现穴位阻抗的测量。
Acupoints are the positions for the Qi and Blood to be injected into human body.The changes in Qi and Blood of human body could be shown as the changes of the corresponding acupoints,such as the changes of electric properties of these acupoints.This paper designsed a hardware system based on the acquisition card PCI8335B,which is mainly composed of AD9833,AD620 and AD8302.To measure the acupoints impedance,VB language is adopted to program the PCI8335B and to collect the electric signal from acupoints.
