Snapless, tabless, disposable medical electrode with low profile
First Claim
1. A snapless, tabless, disposable medical electrode having a low profile for transmitting electrical signals between the skin of a patient and external monitoring equipment, said electrode comprising:
- an adhesive substrate having a top, a central opening and a pressure sensitive adhesive layer on its bottom;
said bottom for facing the patient;
an electrically conductive disk having an underside and formed without a tab and without a snap and positioned over and projecting above said central opening of said substrate by a height of less than about one-sixteenth of an inch;
a conductive electrolytic gel substantially filling said opening of said substrate and adapted to electrically contact the skin of the patient, said substrate, and said disk;
means for securing said disk to said substrate;
a lead wire for connecting said disk to the external monitoring equipment;
means for attaching said lead wire to said disk without regard to orientation; and
a release liner covering said bottom of said substrate and said conductive electrolytic gel before the electrode is secured to the skin of the patient.

Abstract
A snapless, tabless, disposable medical electrode having a low profile for transmitting electrical signals between the skin of a patient and external monitoring equipment. The electrode has an adhesive substrate with a central opening and a pressure sensitive adhesive layer on its bottom (which faces the patient); a symmetrical, electrically conductive disk secured to the substrate, formed without a tab and without a snap, and positioned over and projecting above the central opening of the substrate; a conductive medium substantially filling the opening of the substrate and electrically contacting the skin of the patient, the substrate, and the disk; a lead wire, attached to the disk without regard to orientation, for connecting the disk to the external monitoring equipment; and a release liner covering the bottom of the substrate and gel before the electrode is secured to the skin of the patient.
