1. A disposable electrode comprising:
- a first layer of material having a first surface, a second surface with an adhesive coating for adhesion to the skin of a patient, and defining at least one opening; and
an electrically conductive gel layer mounted on said first surface of said first layer and covering said at least one opening such that said gel layer contacts the skin of the patient through said opening when said electrode is applied to the skin of the patient;
wherein said disposable electrode does not include a conductive terminal.

Abstract
A biomedical electrode for an electrocardiograph or similar device is provided. The biomedical electrode includes a disposable electrode having an electrically conductive gel layer and a reusable leadwire adapter having the relatively expensive metallic conductive material. The disposable electrode interfaces with the reusable leadwire adapter through the adhesive characteristics of the gel layer. The reusable leadwire includes a stud member which snaps into a standard leadwire connector.
