Abstract

A disposable EKG electrode pad is provided with a cut to enable an auxiliary portion of the pad to be lifted out of the plane of the main pad portion. By this arrangement, the main pad portion is pressed against the patient'"'"'s skin and the auxiliary pad portion lifted up and placed over the snap fastener cable extending from the electrode projection on the main portion to hold this cable securely to the patient'"'"'s skin adjacent to the main portion of the pad. Relative movement between the snap fastener and electrode projection on the pad is thus inhibited and thereby artifacts are avoided.

Claims

1. A disposable EKG electrode, including, in combination:

(a) a pad of pliable material including a main portion and an auxiliary portion defined between one edge of the pad and a cut formed in the pad extending from an adjacent edge towards an opposite edge and terminating short of the opposite edge so that part of the auxiliary portion can be lifted away from the plane of the main portion;

(b) an electrode projection carried on the top surface of the main portion;

(c) a conductive jelly carried on the bottom surface of said main portion in electrically conductive contact through the main portion with said electrode projection so that a cable terminating in an electrode snap fastener received on said projection is electrically connected to said conductive jelly; and

,

(d) an adhesive material on the remaining portion of the bottom surface of the pad not covered by said conductive jelly

whereby the bottom surface of the main portion of the pad can be pressed against a patient'"'"'s skin so that the conductive jelly is held against the skin by the adhesion of the main portion of the pad to the skin and the auxiliary portion of the pad lifted away from the plane of the main portion so that the cable can be passed under the auxiliary portion so that the auxiliary portion will overlie at least one portion of the cable extending from the snap fastener and hold the same to the patient'"'"'s skin so as to inhibit relative movements between the snap fastener and electrode projection when portions of the cable beyond said one portion move and thereby avoid generation of artifacts.

2. The subject matter of claim 1, in which there is provided in combination a plastic carrier sheet against which the bottom surface of the pad is pressed to carry the pad during shipment, additional pads being supported and carried by said same sheet so that as the electrodes are to be used, they can successively be peeled away from the plastic carrier sheet.
