摘要

The stimulating current instrument is for treatment of facial nerves and muscles, esp for the treatment of tooth prosthesis. The current pulses are supplied via needles or electrodes which can be placed in the skin. It has a circuit which produces 38 pulses per minute. They alternate between positive pulses of one duration and negative pulses of another duration and a given pulse interval. The output of the instrument has two active and two inactive electrodes. The pulses are selected by a three-position rotary switch (18), which is connected to a two-position toggle switch (19) for pulse and test to produce a permutation of outputs.
