Abstract
Abstract A medical electrode for stimulation iontophoresis monitoring and grounding electrical contact application to the skin surface of humans and animals may be provided having an electrically conductive substrate for interfacing with the skin, an electrically conductive stranded material may be secured to one side of the substrate and an electrically conductive knitted filament material sewn to the stranded material; preferably, a hooked connector is utilized for making an electrical connection with the knitted filament material, this connector being attachable and detachable by means of the coaction of its hooks and knitted filaments.

Claim 1
Independent Claim
58 words
An electrode comprising: a substrate having electrically conductive and adhesive properties; a piece of electrically conductive stranded material adhesively adhered to by one side of said adhesive substrate and being in electrical connection therewith; and a piece of electrically conductive knitted filament material, said knitted material being sewn to said stranded material to make an electrical connection therewith.
Claim 2
Dependent Claim
58 words
An electrode comprising: a substrate having electrically conductive and adhesive properties; a piece of electrically conductive stranded material adhesively adhered to by one side of said adhesive substrate and being in electrical connection therewith; and a piece of electrically conductive knitted filament material, said knitted material being sewn to said stranded material to make an electrical connection therewith.
Claim 3
Dependent Claim
79 words
The electrode of claim 1 also comprising: a Velcro®-type hooked connector, said hooked connector having electrically conductive hooks protruding from a first side therof and having an electrically conductive other side with a conductor lead wire extending therefrom, said hooks being mated with said electrically conductive knitted filament material for completing the electrical connection between said lead wire and said substrate, said hooked connector being attachable and detachable by coaction of said protruding hooks and said knitted filament material.
Claim 4
Dependent Claim
58 words
The electrode of claim 2 wherein said stranded material includes a piece of open-weave mesh material having a conductive coating; wherein said knitted material has a smooth side and a closed loop pile side, both sides having a conductive coating; and wherein said smooth side of said knitted material is sewn to said open-weave mesh material with thread.
Claim 5
Dependent Claim
10 words
The electrode of claim 3 wherein said thread is nonconductive.
Claim 6
Dependent Claim
26 words
The electrode of claim 4 wherein said open-weave mesh material and said knitted material are each made of nylon and said thread is made of cotton.
Claim 7
Dependent Claim
