Abstract

Abstract A skin electrode, comprising a core provided with a pointed portion which projects through an opening in a jacket which is made of a flexible, non-slipping material and which has an integral flat edge. Because of its shape and the material properties, the electrode can be applied on the skin under a comparatively low pressure without sliding.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 177 words
A skin electrode comprising a jacket of flexible insulating material having a central portion and a peripherally extending flat edge portion about said central portion for non-slipping contact with skin; an electrically conductive core extending through the central portion of said jacket and held thereby, said core having at one end a generally conically shaped pointed portion, an apical portion thereof protruding out of the plane of said flat edge portion of said jacket and pointing perpendicularly away therefrom, said core having means for making electrical contact thereto at the other end thereof; and spongy absorbent material covering at least said apical portion of said core, said jacket having a tapered annular flange extending from said central portion and surrounding said conically shaped portion of said core to leave a space therebetween, the peripheral region of said spongy material being received and held in said space between the flange and the conically shaped portion of said core, said annular flange forming a hole through which said spongy material covering said apical portion protrudes for contact with skin.
Claim 2
Dependent Claim 177 words
A skin electrode comprising a jacket of flexible insulating material having a central portion and a peripherally extending flat edge portion about said central portion for non-slipping contact with skin; an electrically conductive core extending through the central portion of said jacket and held thereby, said core having at one end a generally conically shaped pointed portion, an apical portion thereof protruding out of the plane of said flat edge portion of said jacket and pointing perpendicularly away therefrom, said core having means for making electrical contact thereto at the other end thereof; and spongy absorbent material covering at least said apical portion of said core, said jacket having a tapered annular flange extending from said central portion and surrounding said conically shaped portion of said core to leave a space therebetween, the peripheral region of said spongy material being received and held in said space between the flange and the conically shaped portion of said core, said annular flange forming a hole through which said spongy material covering said apical portion protrudes for contact with skin.
Claim 3
Dependent Claim 17 words
A skin electrode as defined in claim 1 wherein the material of said jacket is silicon rubber.
Claim 4
Dependent Claim 34 words
A skin electrode as defined in claim 1 wherein the surface of said flat edge portion of said jacket on the side where said spongy material protrudes is rough for non-slipping contact with skin.
Claim 5
Dependent Claim 25 words
A skin electrode as defined in claim 1 and further comprising an elastic band means for pressing said jacket against the skin of a patient.
