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. The respective reservoir chambers are spaced each from the other by a portion of the base section designated as a barrier segment. The thickness of the material providing the base section, and the minimum width of the barrier segment are selected to insure that upon application of the electrode to the skin of a patient, that the respective chambers, gel pads and terminal assemblies are electrically insulated each from the other by the base section material. Accordingly, upon the application of a pulse to the electrode, current will pass through the underlying tissue in traveling from terminal to terminal.
