Electrocardiographic electrode

Claim 1

Apparatus for deriving a voltage from the heart activity of a person, comprising: an electrocardiographic electrode having: a viscous member to be held in close contact with the skin of the person, the viscous member having front and back viscous surfaces and a central opening, the back surface of the viscous member fixedly securing to the skin of the person; a reinforcement member bonded to the front surface of said viscous base member to close the opening; an electrode member provided in the reinforcement member; first magnetic means fixedly attached to the electrode member; and wherein the electrocardiographic electrode is adaptable to a lead connector having: a water-proof suction member; a lead securement member having a portion extending through the suction member, connected to a lead; second magnetic means fixedly attached to the securement member at the portion extending through the suction member; wherein the lead connector is nondetachably fixed to the electrocardiographic electrode by bonding the inside surface of the suction member to the front surface of the viscous member; and wherein the first and second magnetic means are in abutment to provide an electrical path for the voltage to traverse from the person to an equipment for measuring the voltage; whereby the apparatus is fixedly secured to the skin of the person.
