Body electrode for electro-medical use
First Claim
1. An electrode for use with electromedical equipment and adapted for attachment to a person'"'"'s body, said electrode comprising:
- a. a manually elastically, stretchable, electrically insulating cover sheet member having an inner surface for facing toward the body and an outer surface for facing away therefrom;
b. an electrically conductive sheet member positioned with one surface thereof in juxta-position to the inner surface of the cover sheet member, a first minor area portion of the conductive sheet member adjacent one end thereof being fixedly secured to the cover sheet member, a second major area portion extending to the other end thereof remaining unsecured to said cover sheet member and thereby adapted to permit relative free movement between the cover sheet member and the electrically conductive sheet member, the electrically conductive sheet member being positioned within ther perimetric edge of the cover sheet member;
c. terminal means connected in electrically conducting relation to said conductive sheet member;
d. adhesive means disposed in fixed relation to said cover sheet member for removably attaching the electrode to the body, said adhesive means including first and second separate and distinct adhesive sections, said first section being positioned adjacent one end of the unsecured portion of the conductive sheet member, and the second section being positioned adjacent the opposite end of the unsecured portion of the conductive sheet member and in the vicinity of the secured portion of said conductive sheet member, whereby said elastically stretchable cover sheet member can be stretched between isolated locations of adhesive attachment of the electrode to the body and exert refractive force therebetween

Abstract
This disposable body electrode is constructed so that it can be stretched taut over a portion of a person'"'"'s body to provide both secure attachment and uniformly good electrical contact thereto. The electrode includes an elastic cover sheet, a smaller flexible metallic sheet provided with a male snap fastener protruding through the cover sheet, and a stretchable, porous inner sheet all secured together at one end of the electrode. At the opposite end, only the cover sheet and inner sheet are secured together, thereby leaving the major area of the metallic sheet unsecured between them. An adhesive area is provided at each end of the inner surface of the inner sheet for removably attaching the electrode to the body.

8. An electrode for use with electromedical equipment and adapted for attachment to a person'"'"'s body, said electrode comprising:
-
a. a manually elastically stretchable, electrically insulating cover sheet member having an inner surface for facing toward the body and an outer surface for facing away therefrom; b. a stretchable porous inner sheet member having an inner surface for facing toward the body and an outer surface for facing away therefrom, said porous inner sheet member being adapted to be wetted with an electrically conducting agent and secured at two spaced apart points on the outer surface thereof to the inner surface of the cover sheet member, said inner sheet member being substantially the same size as said cover sheet member; c. an elongated electrically conductive sheet member positioned between, and having one end portion thereof fixedly secured to, said cover sheet member and the inner sheet member, the remaining portion of the conductive sheet member constituting the major portion of the surface area thereof remaining unsecured to both said cover sheet member and said inner sheet member and thereby adapted to permit relative free movement between the elastic cover sheet member and the electrically conductive sheet member over said major area portion;
said conductive sheet member being smaller than both the cover sheet member and said inner sheet member and being positioned with its perimetric edge in inwardly spaced relation to the perimetric edges of the cover sheet member and of the inner sheet member;d. terminal means connected in an electrically conducting relation to said conductive sheet member and extending through the cover member to project outwardly thereof; and e. adhesive means carried by said inner sheet member for removably attaching the electrode to the body, said adhesive means being positioned on the inner surface of the inner sheet member and having first and second separate and distinct adhesive sections, said first section being positioned adjacent one end of the unsecured portion of the conductive sheet member, and the second section being positioned adjacent the opposite end of the unsecured portion of the conductive sheet member and in the vicinity of the secured portion of said conductive sheet member, whereby said elastically stretchable cover sheet member can be stretched between isolated locations of adhesive attachment of the electrode to the body and exert retractive force therebetween. - View Dependent Claims (9, 10)
