Abstract
Abstract The present invention is a patch-type device for iontophoretic transdermal medication of insulin of one-piece form having a container for holding gel-like insulin and a power supply for furnishing insulin with electricity. A patch plate, formed with an embossed portion, electrically contacts an electrode pattern formed in a printed circuit board carried by the device, thereby improving transdermal treatment of insulin.
