Abstract
Abstract A biomedical electrode is disclosed which generally comprises an insulator construction and a conductor member. The conductor member is preferably a thin flat, flexible member having a pad portion and a tab portion. The insulator construction is arranged such that the conductor member pad portion is positioned on one side of the insulator construction and the tab portion is generally positioned on an opposite side. Three general embodiments are disclosed which achieve this: a first comprising two overlapping sections of insulator material, with the tab portion of the conductor member extending outwardly from therebetween; a second in which two sections of insulator construction material are oriented in a substantially coplanar relationship to define a seam therebetween, through which a portion of the conductor member extends; and, a third in which the insulator construction includes a single sheet of material having a slot therein, through which a portion of the conductor member extends. For any of those three embodiments, a substantially flat arrangement results, with advantages associated therewith. Preferred arrangements having a field of conductive adhesive, associated with the pad portion of the conductor member, completely surrounded by a border of insulator construction and skin adhesive, are described.
