Abstract

An EKG electrode is disclosed including a conductive ring positioned around a jelled foam member which is positioned against a surface of a metal contact. The ring may be formed of a conductive medical grade plastic or may be formed by plating a non-conductive ring with a conducting metal.

Claims

1. In an EKG electrode with a body portion to which is attached a conducting contact member in electrical contact with a jell impregnated foam member, an improvement comprising:

means for surrounding said foam member positioned so as to be in physical contact with a part of said body portion as well as in electrical contact with said foam member, and wherein;

said means surrounding comprises a conductive annular ring formed of a selected medical grade plastic.

2. The improved EKG electrode in accordance with claim 1 wherein said annular ring is flexible.

3. The improved EKG electrode in accordance with claim 1 wherein said annular ring is plated with a selected conducting metal.

4. The improved EKG electrode in accordance with claim 1 wherein said annular ring includes a selected quantity of carbon so as to be conductive and wherein said annular ring is flexible.

5. In an EKG electrode with a body portion to which is attached a conducting electrode in contact with a jell impregnated foam member, an improvement comprising:

an annular ring positioned so as to surround and be in electrical contact with said jell impregnated foam member and so as to be in physical contact with a part of said body portion and wherein

said annular ring is formed of a flexible plastic containing a selected amount of carbon so as to be conductive.

6. In an EKG electrode with a body portion to which is attached a conducting electrode in contact with a jell impregnated foam member an improvement comprising:

an annular ring positioned so as to surround and be in electrical contact with said jell impregnated foam member and so as to be in contact with a part of said body portion, and wherein

said annular ring is formed of a rigid plastic which has been plated with a selected conducting metal.

7. The improved EKG electrode according to claim 6 wherein said annular ring is plated with silver.
