A medical electrode intended for short term use has a disposable electrode pad provided with a socket and a reusable electrode conductor which is attached to a lead wire and which has a ridged body adapted to enter and be retained by the socket. The pad includes a pair of spaced foam sheets with patient-contacting adhesive layers on their lower surfaces. An electrolyte gel matrix, preferably formed from conductive adhesive urethane hydrogel, is located between the foam sheets. The socket is formed in a relatively stiff socket plate that overlies the gel matrix and the foam sheets. The socket includes a bore located over the gel matrix shaped to receive the electrode conductor, which is slightly larger than the bore, and may optionally include outwardly extending slits projecting from the bore. A method of manufacturing a strip of the electrode pads on a release liner on a continuous basis is disclosed. In a modification for longer term monitoring uses, the electrode pads are constructed to confine the gel matrix to avoid gel dry out and the socket and the conductor are provided with a cooperating key and keyway for restraining relative movements therebetween.

A disposable medical electrode pad of the type adapted to be removed from a release liner and applied to the skin of a patient for use with a reusable electrode conductor comprising a pair of mutually-spaced foam sheets having mutually substantially coplanar respective upper and lower surfaces, a patient-contacting adhesive on said lower surfaces, and a gap between mutually confronting edges of said sheets, an electrolyte gel matrix filling said gap, a socket plate overlying said gel matrix and overlapping said foam sheets, a said socket plate comprising a sheet of plastic and socket means overlying said gel matrix for removably assembling an electrode conductor in engagement with said gel matrix, and means adhering said socket plate to said foam sheets.
