Abstract

A medical electrode assembly for use with a medical device for monitoring electric impulses from a patient, comprising an electrically conductive lead wire, a connector electrically joined to a first end portion of said lead wire, electrically conductive hook fasteners electrically secured to a second end portion of said lead wire, and an electrode comprising a top portion having electrically conductive loops for removably fastening said hook fasteners thereto, and a bottom portion having an electrically conductive medium in contact with the patient'"'"'s skin and the top portion of the electrode, and an adhesive for removably securing said electrode to the skin.

Claims

1. A medical electrode assembly for use with a medical device for monitoring electric currents from a patient, comprisng:

an electrically conductive lead wire;

a connector electrically joined to a first end portion of said lead wire;

electrically conductive hook or loop fasteners electrically secured to a second end portion of said lead wire, said fasteners having a loop or hook side and an underside where loops or hooks are not present; and

an electrode comprising a top portion having electrically conductive loop or hook fasteners removably connected with hook or loop fasteners, and a bottom portion having an electrically conductive medium for contacting the patient'"'"'s skin, said hook or loop fasteners of said electrode being made of a non-conductive material coated with silver and having a non-loop or non-hook side which forms the bottom portion of said electrode and is coated with a conductive ink containing a mixture of silver and silver chloride to produce a flexible conductive plastic film which does not crack when the electrode is flexed.

2. The medical electrode assembly of claim 1 wherein an adhesive for removably securing said electrode to the patient'"'"'s skin is provided on the bottom portion thereof.

3. The medical electrode assembly of claim 1 wherein said electrically conductive medium is hydrogel.

4. The medical electrode assembly of claim 1 wherein an adhesive donut, having adhesive on each side, is secured to the bottom portion of said electrode with one of said adhesive sides, and provides an adhesive on the other side of the donut for securing to a patient'"'"'s skin, said donut having a center space receiving said conductive medium in the form of a conductive gel.
