Biomedical electrode and method for its manufacture
First Claim
1. A biomedical electrode comprising:
- (a) a backing material coated on a first side with a pressure-sensitive adhesive and having a non-adhesive margin to facilitate the handling of the electrode;
(b) a connector stud located in the backing material, the stud having an electrode plate located on the first side of the backing material for electrical connection to the skin of a patient and, on a second side of the backing material, a head portion to which an electrical connector can be attached;
(c) a strip of ionically-conductive adhesive extending, generally parallel to the non-adhesive margin, across the adhesive-coated first side of the backing material from edge to edge and over the electrode plate of the stud; and
(d) a parallel strip of scrim material located at the interface of the ionically-conductive and pressure-sensitive adhesive, the strip of scrim material being displaced, relative to the electrode plate of the stud, towards the non-adhesive margin of the backing material, and the edges of both strips nearest to the non-adhesive margin being positioned to one side of the electrode plate.

Abstract
A biomedical electrode comprises a connector stud (1) anchored in a patch of adhesive-coated backing material (7) which is used to secure the electrode to the skin of a patient. The connector stud (1), which is located in a pierced opening in the backing material (7), has a head portion (2) to which an electrical lead of an electromedical monitoring/diagnostic system can be attached, and an electrode plate (3) which, when the biomedical electrode is in use, is placed in electrical communication with the skin of the patient. A strip of ionically-conductive adhesive (9) extends across the backing material and over the electrode plate (3) and a strip of scrim material (17) is located adjacent the adhesive coating on the backing material, underneath the adhesive strip (9). The two strips (9, 17) are displaced, relative to the electrode plate (3), towards a tab (13) which is used for removing the electrode from the skin of the patient.
