Dosage control electrode for iontophoresis device

A pieces of the ionization of active medication to infiltrate the electrode module comprises therapy device and skin. The electrode module and a base unit, wherein the base unit comprises A first Water is consumed (oxidation or an original to) and conductive base material; the sacrifice material first upper layer, wherein the first upper cover and base unit first part, sacrificed, the first material is consumed of the base is connected conductive base material. A second upper cover of non-conducting material on the base unit second component, the second upper layer is separated the first upper layer, the period are connected by a base material and thin the plugging area, the bolt is maintained the exposing device for. The ionization connected the pieces therapy device in sacrifice to the material is consumed in turn; The first upper layer is consumed first completely, wherein the base for exposing device for region plugging connection conductive base material is consumed, separating the base unit, the continuity of water interrupts a circuit, so the other end of device. A provided with obvious display is supply wearing device of monitor the reactive and bolt is.
