在针麻动物模型的实验中

需要比较精确的测定电针的刺激参数

以便掌握不同的刺激参数对针麻效果的影响。但是一般针麻仪的刻度都不够精确

而且刺激的脉冲电流也随机体阻抗的大小而变化

因此很难从针麻仪刻度盘上读出精确的刺激参数值。由于针麻仪输出的电流脉冲都很窄(约在0. 3毫For the precise measurement of parameters during acupuncture anesthesia

a sampling resistor isconnected into the output circuit of model 57-6D electroacupuncture apparatus.The current intensity and frequency of electro-acupuncture for stimulation through the organismcan be accurately measured by monitoring the voltage across the sampling resistor.
