| 摘要 |
An electrotherapeutic device for selectively providing iontophoretic or biphasic stimulation to electrodes for introducing iontophoretic substances and for delivering biphasic current to body tissue, comprising timing circuits (120, 270, 280) for providing preselected stimulation intervals, and circuits (10, 30, 50) for providing iontophoretic and biphasic stimulation (151, 152) to the electrodes in response to the timing circuits and a user actuated input (92). The timing circuits may provide alternating intervals of biphasic and iontophoretic stimulation and optionally include a user-actuated one-shot timer (120) for interrupting biphasic stimulation and providing iontophoretic stimulation for a predetermined interval.
