ABSTRACT:
To avoid a reduction of the conductivity in iontophoresis due to the electrical decomposition and the changes in chemical properties of the electrodes themselves, covering by an electrical insulator, and to prevent a drop in the transport rate due to ions freed from the electrode. Provision is made of an electrode structure provided integrally with a reversible electrode and an auxiliary electrode for regeneration of the same and a regeneration current conducting means for conducting a current for regeneration of the reversible electrode when the therapeutic current is off, or the invention is comprised of a reversible electrode and an ion exchange membrane difficult for ions freed from that electrode to penetrate.
