Abstract

Abstract A disposable skin conducting electrode assembly and electrode is disclosed for use on a patient wherein the electrode assembly comprises a gel pad, an electrode and an adhesive pad. The electrode is a thin conductive wire having a non-linear configuration such that the electrode extends across a width of skin substantially greater than the width of the wire. In one particular embodiment, the wire is in a saw-toothed configuration. The gel pad covers one side of the conductive wire, and the adhesive pad covers not only the other side of the conductive wire but the gel pad as well. The adhesive pad is used to hold the electrode assembly to the skin of the patient. A lead wire, connected at one end to the conductive wire, is provided to connect the electrode assembly to a suitable source of electric impulses. The electrode assembly may be used where any electrode is usable but has particular application for transcutaneous electrical nerve stimulation or as a post-operative electrode.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 254 words
A skin conducting electrode assembly for use in supplying electrical impulses to a patient to reduce pain, said electrode assembly comprising, in combination, an electrode comprising a thin conductive member having an undulating configuration along the length thereof such that said member extends across a width of skin substantially greater than the width of said member; means for providing electrical impulses to said conductive member including a lead wire directly connected to said electrode; a gel pad in contact with one side of said electrode, said gel pad extending beyond the configuration of said member to prevent direct contact of said electrode with the skin of the patient; an adhesive pad in adhesive contact with the other side of said electrode, said adhesive pad extending beyond the outer edges of the gel pad to hold the assembly to the patient and to maintain said gel pad and said electrode in electrical contact with the skin of the patient, the configuration of said conductive member providing a wide area of the skin which is in close contact with said electrode, such that said electrode easily stretches and flexes as the skin or said assembly stretches and flexes, a portion of said conductive member extending through said adhesive pad said lead wire being attached to that portion of said conductive member extending through said adhesive pad and said assembly further comprising an adhesive strip secured to said adhesive pad holding said portion of said conductive member and a portion of said lead wire firmly in place.
Claim 2
Dependent Claim 254 words
A skin conducting electrode assembly for use in supplying electrical impulses to a patient to reduce pain, said electrode assembly comprising, in combination, an electrode comprising a thin conductive member having an undulating configuration along the length thereof such that said member extends across a width of skin substantially greater than the width of said member; means for providing electrical impulses to said conductive member including a lead wire directly connected to said electrode; a gel pad in contact with one side of said electrode, said gel pad extending beyond the configuration of said member to prevent direct contact of said electrode with the skin of the patient; an adhesive pad in adhesive contact with the other side of said electrode, said adhesive pad extending beyond the outer edges of the gel pad to hold the assembly to the patient and to maintain said gel pad and said electrode in electrical contact with the skin of the patient, the configuration of said conductive member providing a wide area of the skin which is in close contact with said electrode, such that said electrode easily stretches and flexes as the skin or said assembly stretches and flexes, a portion of said conductive member extending through said adhesive pad said lead wire being attached to that portion of said conductive member extending through said adhesive pad and said assembly further comprising an adhesive strip secured to said adhesive pad holding said portion of said conductive member and a portion of said lead wire firmly in place.
Claim 3
Dependent Claim 20 words
A skin conducting electrode assembly as claimed in claim 1, wherein the undulating configuration of said conductive member is saw-toothed.
Claim 4
Dependent Claim 20 words
A skin conducting electrode assembly as claimed in claim 1, wherein the undulating configuration of said conductive member is sinusoidal.
Claim 5
Dependent Claim 24 words
A skin conducting electrode assembly as claimed in claim 1, wherein the undulating configuration of said conductive member comprises a repeating pattern of loops.
Claim 6
Dependent Claim 18 words
A skin conducting electrode assembly as claimed in claim 1, wherein said conductive member is made of silver.
