Abstract
Abstract A medical electrode assembly (5) for an electrocardiograph or similar device is provided. The medical electrode assembly comprises an electrolyte pad (10) having an electrolyte layer (18) which may be secured to the skin of a patient and a backing member (16) made from a nonconductive material being coextensively superposed directly onto the electrolyte layer (18). The electrolyte pad (10) is used in conjunction with a reusable lead wire connector (12) having at least one surface contacting the electrolyte layer (18) of the electrolyte pad (10). The reusable lead wire connector (12) includes a set of jaws (22,24) which may be compressed together for contacting the electrolyte pad (10). The set of jaws (22,24) may be formed of a nonconductive binder material having a conductive filler dispersed therein. A metallic conductive material (26), such as a silver/silver chloride system, is superposed over the nonconductive binder material.
