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.

Claims

1. 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.

2. 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.

3. 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.

4. The electrode of claim 3 wherein said thread is nonconductive.

5. 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.

6. The electrode of claim 5 wherein said Velcro®

-type hooked connector includes;

a sheet of woven electrically conductive backer material forming said electrically conductive other side;

a plurality of small hooks projecting from one side of said backer material, said hooks being electrically conductive and mechanically interlocked with said backer material weave, and being said electrically conductive protruding hooks from said first side;

an eyelet secured through said backer material, said eyelet being swaged together of two electrically conductive members being crimped one upon another; and

wherein said conductor lead wire is electrically conductive and has a section wound around one of said eyelet members and being held fast thereto by said crimp.

7. The electrode of claim 6 also including at least one foam pad section, said section having at least one side covered with adhesive and adhered to an otherwise exposed portion of said open-weave mesh material.

8. The electrode of claim 7 wherein said connector backer material and said connector plurality of hooks are coated with an electrically conductive substance.

9. The electrode of claim 8 wherein said electrically conductive substance includes carbon.

10. The electrode of claim 8 wherein said electrically conductive substance includes silver.

11. The electrode of claim 8 wherein said electrically conductive substance includes gold.

12. An electrode comprising:

a substrate sheet having electrically conductive and adhesive properties; and

a piece of electrically conductive knitted material, said knitted material having a smooth side and a closed loop pile side both of which are electrically conductive, said knitted material being of the approximate shape and size of said substrate sheet and being adhered to by one side of said substrate sheet on said knitted material'"'"'s smooth side.

13. The electrode of claim 12 also including an electrical connection member having a plurality of electrically conductive hooks, said hooks being mated with said knitted material closed loop pile side to make an electrical connection therewith.
