The viscous base member with the opening is viscous both on the back side, to be held in close contact with the skin, and on the front side, to be coupled to the lead connector.

Abstract: A multi-electrode type electrocardiographic electrode structure includes a base member made of non-woven cloth, electrode and lead sections formed by using a liquid conductor printed on or impregnating the base member, the electrode section consisting of a plurality of electrodes arranged on the base member, the lead section being connected to the individual electrodes, an electrolyte material provided on the electrodes and serving to reduce the resistance of the skin of a living body, and an insulating adhesive material provided on the base member to alternate with the electrodes for permitting the electrocardiographic electrode structure to be held in close contact with the living body.

Abstract: An electrocardiogram electrode pad has elasticity and flexibility and encloses an electrocardiogram electrode to be held in close contact with the skin surface of a man to derive a weak current therefrom. The electrocardiogram electrode pad having a bottom wall to be held in contact with the skin surface of the man and a side wall extending from the edge of the bottom wall to be fitted on the electrode section of electrocardiogram electrode. The side wall has a greater thickness for its free end portion than its intermediate and stem portions. The side wall has a pinch portion projecting from the free end to be pinched when fitting and removing the electrocardiogram electrode pad with respect to the electrocardiogram electrode.

Abstract: An electrocardiographic current derivation electrode is disclosed, which consists of a substantially rectangular lamination consisting of a resin film, a deposited silver layer formed on one surface of the resin film, a conductive adhesive layer coated on the deposited silver layer and a foamed sheet applied to the outer surface of the resin film. The electrocardiographic current derivation electrode is formed in a substantially central portion thereof with a substantially parallelogrammic terminal. One short side of the terminal is foldably united to the rest of the electrocardiographic current derivation electrode, the other three sides of the terminal are cut sides, and the long cut sides of the parallelogram are not parallel to the long sides of the substantially rectangular electrocardiographic current derivation electrode.

Abstract: An electrocardiographic electrode is disclosed, which is to be held in close contact with a person's skin for deriving a weak voltage from an inner part of the person. The electrode includes a viscous base member to be held in close contact with the person's skin and having a central opening, a reinforcement member bonded to the front surface of the viscous base member to close the opening, a lead connector hook penetrating a central portion of the reinforcement member to be coupled to a lead connector, and an electrode member secured to the underside of the lead connector hook.
