Abstract
Abstract A disposable biomedical electrode of the type adapted for connection by a clip-on connector to a lead wire, comprising a semi-flexible composite sheet member having a non-conductive upper layer and an electrically conductive current distributing lower layer, and a layer of biomedical electrically conductive pressure sensitive adhesive on an electrode section of the sheet. A layer of resilient foamed plastic is fixed on the non-conductive upper layer of the electrode, on a portion of the tab section of the semi-flexible sheet, to enhance gripping of the tab section by the clip-on type connector assembly.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
183 words
A disposable biomedical electrode of the type adapted for connection by a clip-on connector assembly to a lead wire, comprising, a semi-flexible composite sheet member having a non-conductive upper layer at an upper side and a conductive lower current distributing layer at a lower side, the semi-flexible sheet member having an electrode section and an integral tab section, a layer of biomedical electrically conductive, pressure sensitive adhesive adhered to the conductive lower current distributing layer of the sheet member only on the electrode section such that the conductive lower current distributing layer remains exposed on the tab section, the improvement comprising a layer of resilient foamed plastic fixed on the non-conductive upper layer of the electrode on only a portion of the tab section of the semi-flexible sheet member that is spaced along the tab section in a direction away from the pressure sensitive adhesive on the electrode section to enhance gripping of the tab section by the clip-on type connector assembly and facilitate flexing of the tab section in the area intermediate the electrode section and the layer of resilient foamed plastic.
Claim 2
Dependent Claim
183 words
A disposable biomedical electrode of the type adapted for connection by a clip-on connector assembly to a lead wire, comprising, a semi-flexible composite sheet member having a non-conductive upper layer at an upper side and a conductive lower current distributing layer at a lower side, the semi-flexible sheet member having an electrode section and an integral tab section, a layer of biomedical electrically conductive, pressure sensitive adhesive adhered to the conductive lower current distributing layer of the sheet member only on the electrode section such that the conductive lower current distributing layer remains exposed on the tab section, the improvement comprising a layer of resilient foamed plastic fixed on the non-conductive upper layer of the electrode on only a portion of the tab section of the semi-flexible sheet member that is spaced along the tab section in a direction away from the pressure sensitive adhesive on the electrode section to enhance gripping of the tab section by the clip-on type connector assembly and facilitate flexing of the tab section in the area intermediate the electrode section and the layer of resilient foamed plastic.
Claim 3
Dependent Claim
42 words
A disposable biomedical electrode according to claim 1 wherein said layer of resilient foamed plastic has a nominal thickness substantially greater than the thickness of said semi-flexible sheet member and a compressibility substantially greater than the compressibility of said semi-flexible sheet member.
Claim 4
Dependent Claim
32 words
A disposable biomedical electrode according to claim 2 wherein said layer of resilient foamed plastic comprises a closed cell polyethylene copolymer having a density of 2 to 6 pounds per cubic foot.
Claim 5
Dependent Claim
29 words
A disposable biomedical electrode according to claim 1 wherein said semi-flexible sheet member comprises an upper sheet of non-conductive plastic material and a lower layer of electrically conductive material.
Claim 6
Dependent Claim
34 words
A disposable biomedical electrode according to claim 1 wherein said semi-flexible sheet member comprises an upper sheet of non-conductive plastic material and a lower sheet of electrically conductive metal adhered to the upper sheet.
