A circuit description for a multichannel constant current source for microiontophoresis is presented. The circuitry allows a high voltage compliance, accurate monitoring of ionotophoretic current without use of batteries, and automatic current neutralization. Drugs may be applied either manually or with an external digital gate signal. A monitor to detect current unbalance greater than a preselected level is also included.
本文介绍了一种用于微离子电渗疗法的多通道恒流源的电路描述。该电路具有高电压耐受性，无需使用电池即可精确监测离子电渗电流，并能实现自动电流中和。药物可以手动施加，也可以通过外部数字门信号施加。此外，还包括一个用于检测电流不平衡大于预选水平的监视器。
