Waterproof electrode assembly with transmitter for recording electrocardiogram
First Claim
1. Apparatus for recording an electrocardiogram comprising a waterproof electrode assembly, said electrode assembly having a plurality of electrodes, and each of said electrodes comprising:
- (a) a cup-shaped suction disc constructed from a waterproof, elastic material, said disc having a concave side, a convex side and a through-hole at the center thereof;
(b) an electrode plate having an outer peripheral edge hermetically sealed to the concave surface of said suction disc and closing said through-hole;
(c) a lead wire extending from said electrode plate past the convex surface of said suction disc;
(d) elastic sealing means for hermetically sealing together the outer peripheral edge of said electrode plate and the portions of the concave surface of said suction disc in contact with said peripheral edge of said electrode plate;
(e) elastic sealing means hermetically sealing the lead wire at the convex surface of the suction disc;
(f) an annular, body-surface adherent strip surrounding said electrode plate and bonded to the concave surface of the suction disc; and
(g) a wireless transmitter connected to said electrode.

Abstract
A waterproof electrode assembly with a transmitter for recording an electrocardiogram, in which the electrodes can reliably be attached on the outer surface of a human body due to bonding force of the adherent sheet and the sucking force caused by returning action of a cup-shaped suction disk to its original shape, the electrodes are not separated from the body even during severe exercise in the water, such as swimming. The waterproofness of the electrode assembly is reliable and durable, and the electrocardiogram of the living body during swimming can be efficiently and accurately recorded, no current leakage phenomenon occurs, the entanglement of the cable with legs and arms can be removed.
