Device for the delivery of a substance to a subject and improved electrode assembly
First Claim
1. A device for the delivery of a substance to a subject, comprising:
- (a) control means for controlling the delivery of a substance to a subject, comprising a power source and a pair of electrically conductive contacts;
(b) a substrate having a first surface and a second surface;
(c) a pair of spaced apart electrodes fixed to the first surface of the substrate for the delivery of a substance from a supply thereof to the skin surface of a subject;
(d) a pair of electrical couples adapted to affect electrical communication between the conductive contacts of the control means and the spaced apart electrodes when each of the electrically conductive contacts of the control means and the electrodes are affixed to one another, each couple being integral with one of the electrodes and fixed to the first surface of the substrate; and
(e) adhesive on the second surface of the substrate for adhering the pair of electrically conductive contacts of the control means and the pair of electrical couples to one another, whereby when each of the electrical couples is folded away from itself, electrical communication is made between the pair of electrodes and the power source.

Abstract
The invention is directed to a device for delivering a pharmaceutically active compound or cosmetic substance to a subject comprises a flexible substrate sheet attached to an electronic controller. The controller is provided with a pair of electrical contacts on the underside thereof and is adhered to the sheet by means of a pair of strips of electrically conductive adhesive. The underside of the sheet is printed in two halves with electrically conductive ink to provide a pair of electrodes separated by an insulating barrier. A protuberance extends from each electrode and is folded onto the top of the sheet such that the contacts of the controller are adhered in electrical connection with the protuberances and thus also with the electrodes. The use of an adhesive to connect a controller in electrical communication with the electrodes enables an extremely simple construction of delivery device to be achieved.
