Estimating the term…
A disposable electrode assembly for establishing electrical contact with an underlying skin surface includes a relatively thin base member having a central hub portion and an adhesive-coated undersurface, a conductive gel-impregnated sponge contact contained in a downwardly facing recess located in the hub, and a relatively thick and inflexible cover member coextensive with the base member. In storage the cover member is attached to the undersurface of the base member by the adhesive and the sponge is confined within the recess. Prior to use the base member is peeled away from the cover member to expose the adhesive surface, which when applied to a skin surface holds the sponge contact in compression-contact therewith. A thumb recess is provided along the margin of the cover member to facilitate removal of the cover member.

A disposable electrode assembly for establishing an electrical connection to an underlying skin surface comprising, in combination:
In a disposable electrode assembly for establishing an electrical connection with an underlying skin surface, said electrode assembly comprising a relatively flexible base member formed of electrically-insulating material defining an outside surface and an adhesive carrying inside surface, said base member carrying an electrically conductive terminal on said inside surface and adapted for holding said terminal in contact with the skin surface, said terminal communicating with said outside surface, and a cover member being, overall, substantially less flexible than the major extent of said base member, said cover member having an inside surface attached to and being substantially coextensive with said adhesive carrying surface so as to enclose said terminal and increase the rigidity of said electrode assembly during storage, the improvement wherein said cover member includes a thumb recess about its margin at the inside surface to facilitate peeling said base member away from said cover member to enable said adhesive carrying inside surface to be placed in contact with the underlying skin surface to hold the electrically conductive terminal in contact with the skin while the electrode assembly is in use.
In a disposable electrode assembly for establishing an electrical connection with an underlying skin surface, said electrode assembly comprising a relatively flexible base member formed of electrically-insulating material defining an outside surface and an adhesive carrying inside surface having an open-ended chamber thereon, said base member containing within said chamber a sponge-like electrical contact member projecting outwardly in an expanded state beyond said adhesive carrying surface, said contact member having a portion communicating with the outside surface, and a cover member being, overall, substantially less flexible than the major extent of said base member, said cover member having an inside surface attached to and being substantially coextensive with said adhesive carrying surface so as to enclose said sponge-like contact member in a compressed state within said chamber and increase the rigidity of individual ones of said electrode assemblies during storage, the improvement wherein said cover member includes a thumb recess about its margin at said inside surface to facilitate peeling said base member away from said cover member to enable said adhesive carrying inside surface to be placed in contact with the underlying skin surface to hold the sponge-like contact member in contact with the skin while the electrode assembly is in use.
