Abstract: There is disclosed a transcutaneous electrode construction for the application of electrical pulses to a patient, such as might be employed in pain therapy. The electrode construction includes a base member comprising a sheet of nonconductive material having an adhesive coating on one surface. A thin liquid impervious nonconductive sheet of smaller surface area than the base member is centrally affixed thereto on the adhesive coated surface so as to be entirely surrounded by the adhesive coating. A sponge pad overlies the liquid impervious sheet and has a larger surface area than the liquid impervious sheet so that its peripheral edges engage and adhere to the adhesive of the base member while leaving sufficient adhesive surface exposed for adhering to the skin of the patient. Due to the fact that the sponge pad is adhered to the base member only about the edges thereof, a chamber or pocket is formed between the sponge pad and the impervious sheet for receiving a quantity of electrolytic gel.

Abstract: There is disclosed, a disposable, preferably pregelled electrode construction for the transcutaneous application of electrical pulses to provide a stimulus thereby producing involuntary neuromuscular contractions. The electrode is comprised of a base section formed from non-conductive material such as cellular plastic foam. At least two closed-bottom reservoir chambers are formed in the base section for housing a quantity of electrolytic gel, with a cellular sponge-like pad disposed in each chamber and saturated with said electrolytic gel. An electrical terminal assembly is provided for each reservoir chamber in the form of a two-piece snap-type fastener mounted to the base section through the bottom wall of the chamber. Each terminal assembly includes an inner eyelet in surface engagement with the gel pad, and an outer stud engaged with said eyelet for connection to an electrical lead from a pulse generator.

Abstract: There is disclosed an ECG monitoring device for attachment to the skin of an individual, which device includes a plurality of electrodes for monitoring bio-skin potential disposed at suitable locations on a base or substrate. The device includes a first resilient sponge-like sheet, and a second resilient sponge-like sheet adhesively attached to the first sheet and having a plurality of openings formed therein. A number of electrodes are attached to the second sheet by an adhesive coating, with the connector elements of the respective electrodes in place in the openings and secured to lead wires for attachment to monitoring apparatus. The individual electrodes include an adhesive base surface that can be exposed upon removal of a cover structure which normally overlies a pre-gelled pad and said base surface. The adhesively coated base surfaces of the electrodes are used to affix the device to the patient.

Abstract: There is disclosed a novel electrode assembly or package for two or more electrode devices, and also a novel method of fabricating not only the overall assembly, but also the devices in conjunction therewith. The electrode assembly as contemplated by the disclosure includes a carrier member in generally strip form having one or more openings therein, the number of said openings depending upon and being equal to one-half of the number of electrode devices to be employed in said assembly. A medical electrode device is secured in overlying relation to each opening, on opposite sides of the carrier member, with the gel pads of each said electrode device being disposed within the periphery of the opening and in face-to-face contact with the pad of the opposed electrode device. The electrode devices may be pre-gelled, if desired. It is contemplated that the assembly may then be packaged in a suitable container, such as a plastic or foil envelope.
