US Patent 7668604 Packaging for medical pads and electrodes

Disposable biomedical pads include a conductive outer layer with an adhesive conductive protected layer on a major portion of the outer layer, with a double-sided release layer over the protected layer. Two pads are folded against each other, with the edges sealed to protect the gel layer from the environment. In use, the release layer is discarded, the gel layer placed against the skin, and in the case of defibrillation pads, the paddles are applied directly to the outer conductive layer. The outer layer serves as the packaging layer as well as the dispersive electrode.
