Abstract
A cup for use in medical electrode structures comprises a one-piece body of plastic having a cup shape and thus having a base and a rim. The rim is rounded for comfortable skin contact and has integrally formed barbs projecting inwardly and downwardly toward the center of the cup. The barbs permit a prefilled electrolyte sponge to be dropped into the cup without appreciable resistance from the barbs, but resist any tendency for the prefilled sponge to separate from the cup. Accordingly the cup supports the prefilled electrolyte sponge for contact to the skin of a patient but resists any tendency of the sponge to escape the cup by clinging to the patient's skin.
