Waterproof electrode for recording electrocardiogram

摘要

Waterproof electrodes for recording an electrocardiogram, in which one end of a lead wire is inserted from the convex surface side to the concave surface side of a cup-shaped suction disc made of waterproof elastic material into a through hole formed at the center of the disc, an electrode plate connected to the end of the lead wire is put on the concave surface side of the suction disc to close the hole, the contacting portion between the outer peripheral edge portion of the plate and the concave surface of the suction disc and the gap between the periphery of the wire and the convex surface of the suction disc are respectively hermetically sealed by elastic sealing material, and an annular body surface adherent sheet capable of hermetically sticking on the surface of a human body along the concentric circle surrounding the electrode plate is bonded on the concave surface of the disc.
