Abstract
Abstract A biomedical electrode (10) adapted to be applied to a body, the biomedical electrode (10) having a surface area divided into a first zone (38), a second zone (40), and a third zone (42). The biomedical electrode (10) has a first layer of adhesive (24) which is electrically conductive and which is adapted to be applied to the body, a conductive layer (22) positioned adjacent the first layer of adhesive (24), a second layer of adhesive (16), and a protective, electrically insulative web (12) positioned adjacent the second layer of adhesive (16). The second layer of adhesive (16) holds the protective, electrically insulative web (12) to the conductive layer (22) in the third zone (42) of the biomedical electrode (10). A removable release liner (18) is positioned in the first zone (38) between the second layer of adhesive (16) and the conductive layer (22) preventing the protective, electrically insulative web (12) from sticking to the conductive layer (22) in the first zone (38) of the biomedical electrode (10). An insertable electrical lead wire (14) is insertable in the first zone (38) between the second layer of adhesive (16) and the conductive layer (22) upon removal of the removable liner (18). The protective, electrically insulative web (12) has an edge (44) in the second zone (40) which is easily grasped so that the protective, electrically insulative web (12) may be pulled and removed from the biomedical electrode (10) allowing removal of the electrical lead wire (14).
