ELECTROTRANSPORT DEVICE HAVING REUSABLE CONTROLLER

PROBLEM TO BE SOLVED: To provide an electrotransport system which can securely perform electrical connection of correct polarities between a drug-containing unit and a controller. SOLUTION: An electrotransport system 10 includes a reusable controller 12 having a power source and a separably disposable drug-containing unit 30 which contain both a donor electrode and a counter electrode. Coupling means 36, 38 of the drug unit side and coupling means of the controller side corresponding thereto physically and electrically connect together the controller 12 and the drug unit 30. The controller 12 provides electrical current to the drug unit 30 for electrotransport delivery of the drug to a body surface (e. g., the skin) of a patient. The coupling means 36, 38 and coupling means of the controller side corresponding thereto ensure correct polarity connection of the donor and counter electrodes to the outputs of the controller 12.
