Medical electrode with reusable conductor and method of manufacture

Abstract From the Canadian patent

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 …
