Abstract
An improved iontophoretic device for introducing an ionic substance into body tissue. A compact casing contains all the electronic circuitry necessary for generation and control of an iontrophoretic current. Stainless steel electrode plates are mounted directly on the casing and are electrically coupled to the electronics within. The device may be used in a simplified iontophoretic procedure: adhesive pads containing the ionic substance to be driven into the body tissue are applied to the stainless steel plates and the entire iontophoretic device is then affixed to the body by the adhesive pads and a safety strap, thus permitting normal patient movement during the iontophoretic process.
