Abstract

A stud/eyelet for a biomedical electrode is disclosed. The stud/eyelet has at least one hole in the base to reduce manufacturing cost, provide increased surface contact with ionically conductive media, and to increase anchorage for the ionically conductive media.

Claims

1. A stud/eyelet for a biomedical electrode, comprising:

a base having an outer perimeter, a neck connected to the base, and a head connected to the neck, wherein the base has at least one hole therein and a recess extending from at least one hole to the outer perimeter of the base.

2. The stud/eyelet of claim 1, wherein each hole is of substantially constant diameter.

3. The stud/eyelet of claim 1, wherein each hole is frustroconical.

4. The stud/eyelet of claim 1, wherein each hole is angular.

5. The stud/eyelet of claim 1, wherein each hole is curved.

6. The stud/eyelet of claim 1, wherein at least one recess contacts a perimeter of the base in a manner to form a groove.

7. A biomedical electrode, comprising:

a nonconductive backing having an aperture;

a stud/eyelet wherein the stud/eyelet comprises a base having an outer perimeter, a neck connected to the base, and a head connected to the neck and extending through the aperture, wherein the base has at least one hole therein and a recess extending from at least one hole to the outer perimeter of the base; and

a field of conductive adhesive contacting the base.

8. The biomedical electrode of claim 7, wherein each hole is of substantially constant diameter.

9. The biomedical electrode of claim 7, wherein each hole is frustroconical.

10. The biomedical electrode of claim 7, wherein each hole is angular.

11. The biomedical electrode of claim 7, wherein each hole is curved.

12. The biomedical electrode of claim 7, wherein at least one recess contacts a perimeter of the base in a manner to form a groove.

13. The biomedical electrode of claim 7, wherein the stud/eyelet is secured to the backing using adhesive in at least one hole.
