IONTOPHORESIS DEVICE

摘要

Disclosed is an iontophoresis device wherein at least one electrode structure comprises a composite ion exchange membrane which is composed of a laminate of a first ion exchange membrane of a first conductivity type and a second ion exchange membrane of a second conductivity type, or a laminate of a first ion exchange membrane of a first conductivity type, a semipermeable membrane and a second ion exchange membrane of a second conductivity type. In each laminate, the constituting membranes are integrally joined with each other. In this iontophoresis device, the first ion exchange membrane of the first conductivity type which is arranged on the living body interface is doped with drug ions of the first conductivity type. Also disclosed is an iontophoresis device, wherein two ion exchange membranes of the opposite conductivity type are interposed between an electrolyte solution holding unit and a drug solution holding unit containing drug ions of a first conductivity type, which can be automatically mass-produced by a simple process at reduced cost.
