Abstract
Abstract A biomedical electrode (10) adapted to be applied to a body (34). The electrode (10) has a backing material (16), preferably foam, having an aperture (20). A protective web (12) at least partially secured to the backing material (16) covers the aperture (20). A removeable liner (18) is positioned between the protective web (12) and the backing material (16). An electrically conductive adhesive (28) is positioned adjacent the backing material (16) on the opposite side from the protective web (12). A second removeable release liner (30) is positioned adjacent the electrically conductive adhesive (28) opposite from the backing material (16). A lead wire (22) having a conductive portion (24) is insertable under the protective web (12) to be secured there upon the removal of the release liner (18), by the protective web (12) and the electrically conductive adhesive (28). A bottom release liner (30) may be removed and the biomedical electrode (10) may be secured to a body (34). The conductive portion (24) of the lead wire (22) should be silver or silver plated and preferably subjected to chloride treatment.
