ABSTRACT:
An electrode for attachment to the skin includes an electrode body of flexible sheet material coated with adhesive for attachment to the skin and manufactured of either liquid absorbent or liquid impervious material. Attached to this flexible sheet by a male snap fastener member is a liquid vapor barrier sheet which is likewise coated with adhesive for adhesion to a liquid absorbent sponge member which is filled with electrolyte. A thin, moisture impervious carrier sheet is attached to the adhesive coating on both the moisture impervious sheet and the flexible body and is additionally attached, through a heat sealing process, to a cup member which prohibits evaporation or migration of the electrolyte from the liquid absorbent sponge member prior to use. A soft, flexible, annular sealing member may be attached to the moisture and liquid vapor barrier sheet to surround the electrolyte-filled sponge member during use to prohibit migration of electrolyte between the adhesive coated sheet and the patient's skin. This construction results in a long shelf life electrode which may be effectively used on a patient for extended periods of time.
