Abstract
Abstract Electrode such as a TENS or post-operative electrode including a backing of plastic foam or dielectric material with an adhesive layer, an electrical communication conductor member such as a metal stud, such as of aluminum or silver, a thin polymer material with a conducting layer such as carbon or a conductive medium, an insulation retention disc coated with adhesive on both sides, a liner release, a gel protector, and an adhesive cover. The foil conductive member and polymer member are thin, providing for flexibility and low profile, and are substantially of like identical surface area. The conductive coating can be either Karaya, rodel or any conductive coating with a liner, or the user can apply a gel. The electrode is very flexible and very conforming to the surface of the skin of the individual user.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
273 words
Electrode comprising: a. vinyl backing material including a layer of adhesive disposed over a bottom portion thereof and of a first outer diameter and including a first eyelet opening; b. conductive thin polycarbonate carbon impregnated film including a vapor deposited metalized layer disposed on a top side thereof and of said first outer diameter, said metalized layer adhering to said adhesive of said backing material and including a second eyelet opening; c. insulating retention disc including an internal opening of a round hole of a second diameter, said second diameter being less than said first diameter, adhesive positioned on both sides thereof and said disc being of said first outer diameter, said disc adhering to said film by said adhesive on one side of said disc and including a conductive gel in the opening of said disc; d. eyelet extending through said second eyelet opening through said film with said metalized layer and through said first eyelet opening in said backing material, said first opening slightly larger in diameter than said second opening, said eyelet including a flat base member which engages in electromechanical contact against said film; and, e. metal stud electromechanically secured over said eyelet and holding in engagement said thin film and said metalized layer and said backing layer, a bottom side of said metal stud electrically and mechanically communicates in engagement with a top area of said metalized film about a circumference radius of said metal stud in an area provided between difference in area of said second and first openings whereby said electrode is low profile and flexible, thereby providing consistent conformity on placement on an individual's skin.

Electrode comprising: a. vinyl backing material including a layer of adhesive disposed over a bottom portion thereof and of a first outer diameter and including a first eyelet opening; b. conductive thin polycarbonate carbon impregnated film including a vapor deposited metalized layer disposed on a top side thereof and of said first outer diameter, said metalized layer adhering to said adhesive of said backing material and including a second eyelet opening; c. insulating retention disc including an internal opening of a round hole of a second diameter, said second diameter being less than said first diameter, adhesive positioned on both sides thereof and said disc being of said first outer diameter, said disc adhering to said film by said adhesive on one side of said disc and including a conductive gel in the opening of said disc; d. eyelet extending through said second eyelet opening through said film with said metalized layer and through said first eyelet opening in said backing material, said first opening slightly larger in diameter than said second opening, said eyelet including a flat base member which engages in electromechanical contact against said film; and, e. metal stud electromechanically secured over said eyelet and holding in engagement said thin film and said metalized layer and said backing layer, a bottom side of said metal stud electrically and mechanically communicates in engagement with a top area of said metalized film about a circumference radius of said metal stud in an area provided between difference in area of said second and first openings whereby said electrode is low profile and flexible, thereby providing consistent conformity on placement on an individual's skin.
Claim 3
Dependent Claim
169 words
Electrode of claim 1 comprising: a. release layer including top and bottom surfaces, said top surface being supported on said adhesive side of said disc opposite said side of said film support, said release layer including a like geometrical configuration of said first outer diameter of said insulating retention disc, and including an opening of a round hole of said second diameter; b. gel protector having a slightly larger geometrical shape than said opening of said second diameter in said release layer and supported on a bottom surface of said release layer and forming a pocket about a hole of a second diameter in said release layer; and, c. covering including adhesive on a top side thereof supported on the bottom surface of said release layer by said adhesive on said top side thereof and of said first outer diameter whereby said adhesive covering and release layer encompass said gel protector, and said gel protector holding and protecting gel held within said pocket formed in said insulating retention disc.
Claim 4
Dependent Claim
40 words
Electrode of claim 1 comprising: a. cover of said first outer diameter disposed over said insulating retention disc, over said adhesive on the side of said disc opposite the side of said film support whereby said cover protects said electrode.
