Abstract
A transdermal drug applicator for application to the skin or membrane of a patient and which is electrically powered. The applicator includes a flexible, non-conductive substrate having a plurality of conductive coated areas. The conductive coated areas include drug reservoir electrodes. The flexible substrate and the conductive coated areas form a single, substantially flat, flexible member. A plurality of separate drug reservoirs are in electrical contact with the drug reservoir electrodes. At least one battery is connected in series with the drug reservoir electrodes. The flexible substrate has opposed flat surfaces, the electrically conductive coated areas being electrically conductive coated areas on the flat surrfaces. Electrical connection between the conductive coated areas in the vicinity of each reservoir is provided by electrically conductive material extending into a single hole, small holes, or slots which extend between the opposed surfaces of the substrate.
