Abstract
Abstract A biomedical body electrode is provided having a nonconductive housing with an apertured face for application to a body surface. A metallic element is mounted within the housing, the element and the face defining a cavity therein. An electrolyte fills the cavity and a membrane is secured to the face to cover the apertures, thereby sealing the electrolyte within the cavity. A lead is connected to the metallic element for connecting the electrode to external instrumentation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
136 words
An electrode for establishing electrical contact with a body surface of a living organism, said electrode comprising: a nonconductive housing having a face at one end for contacting said body surface, said face having an aperture therein; a metallic element mounted at the other end within said housing in spaced parallel relation to said face whereby said metallic element and said face define a cavity within said housing; an electrolyte filling said cavity; a membrane secured to said face to cover said aperture, said membrane being impermeable to said electrolyte thereby to seal said electrolyte within said housing, said membrance being permeable to at least one selected wetting agent, for dampening said membrane whereby to enhance the electrical conductivity thereof; and an electrical lead connected to said metallic element for connecting said electrode to external instrumentation.
Claim 2
Dependent Claim
136 words
An electrode for establishing electrical contact with a body surface of a living organism, said electrode comprising: a nonconductive housing having a face at one end for contacting said body surface, said face having an aperture therein; a metallic element mounted at the other end within said housing in spaced parallel relation to said face whereby said metallic element and said face define a cavity within said housing; an electrolyte filling said cavity; a membrane secured to said face to cover said aperture, said membrane being impermeable to said electrolyte thereby to seal said electrolyte within said housing, said membrance being permeable to at least one selected wetting agent, for dampening said membrane whereby to enhance the electrical conductivity thereof; and an electrical lead connected to said metallic element for connecting said electrode to external instrumentation.
Claim 3
Dependent Claim
31 words
The electrode as recited in claim 1 wherein said face has a plurality of apertures therein, and said membrance is secured to said face to cover all of said several apertures.
Claim 4
Dependent Claim
17 words
The electrode as recited iN claim 1 including means for attaching said electrode to said body surface.
Claim 5
Dependent Claim
57 words
The electrode as recited in claim 3 wherein said attaching means comprises an annulus, said annulus being secured to said face surrounding the area of said membrance covering said aperture whereby to expose said membrane area to said body surface, said annulus having an adhesive surface on the side thereof to be applied to said body surface.
Claim 6
Dependent Claim
16 words
The electrode as recited in claim 1 wherein said membrane is polytetrafluorethylene embedded with fiber glass.
Claim 7
Dependent Claim
23 words
The electrode as recited in claim 5 wherein said housing in nonconductive plastic and said metallic element is a silver silver chloride tablet.
Claim 8
Dependent Claim
31 words
The electrode as recited in claim 6 wherein said face has a plurality of apertures therein and said membrance is secured to said face to cover all of said several apertures.
Claim 9
Dependent Claim
66 words
The electrode as recited in claim 7 including means for attaching said electrode to said body surface, said attaching means comprising an annulus, said annulus being secured to said face surrounding the area of said membrance covering said apertures whereby to expose said membrane area to said body surface, said annulus having an adhesive surface on the side thereof to be applied to said body surface.
