IONTOPHORESIS DEVICE AND METHOD OF ASSEMBLING THE SAME

摘要

An iontophoresis device that can guarantee a long-term stability of drug and can be easily assembled during drug application, and a method of assembling the device. A donor electrode printed portion (6) of a backing layer (4) is provided with a drug dissolving portion (11), to which a drug carrier (14) is removably joined. The device is attached with a liner (12) on the skin (40) side, which is removed during the use of the device. The liner (12) is formed with an opening (15), and an electrode portion (Ib) is formed with an opening (5). During assembly of the device, these openings are aligned to enable the drug carrier (14) to be easily and accurately positioned at the drug dissolving portion (11).
