Biomedical electrode

Claim 1

A biomedical electrode comprising: a. an electrical terminal member comprising a base having upper and lower major surfaces and a post integral with said upper surface of said base and extending therefrom, said post presenting an exposed surface for direct physical and for electrical connection to a lead wire of an electromedical device; b. an ionically conductive layer in physical and electrical contact with said lower major surface of said base and extending peripherally from said base, and c. a retainer sheet having upper and lower major surfaces bound together by an edge surface and having an aperture there through that is spaced apart from the edge surface and dimensioned to receive and to surround said post, said retainer sheet extending outwardly from said post beyond said base contacting said lower major surface of said retainer sheet and said ionically conductive layer to positionally confine said electrical terminal member between said retainer sheet and said ionically conductive layer.

Claim 8

A method of manufacturing biomedical electrodes comprising the steps of: a. cutting apertures at predetermined locations along the length of a first release liner; b. laminating a medical tape comprising a backing having a pressure-sensitive adhesive coating on at least one major surface thereof to the release liner whereby the adhesive-coated surface of said tape is adhered to the release liner; c. cutting said medical tape transversely between each of said apertures; d. laminating a series of retainer sheets having upper and lower major surfaces bound together by an edge surface to said medical tape through each of said apertures in said first release liner whereby said retainer sheets are adhered through said apertures to said adhesive-coated surface of said tape: e. cutting an aperture through said retainer sheets and on through said medical tape; f. locating an electrical terminal member comprising a base having upper and lower major surfaces and an upstanding post integral with said upper major surface of said base in each aperture in each retainer sheet and in the medical tape by extending said post of said terminal member through said aperture until said upper major surface of said base contacts the lower surface of said retainer sheet; g. laminating an ionically conductive layer to the lower surface of said each base and the lower surface of each retainer sheet through said apertures in said first release liner; h. laminating a second release liner to said conductive layers opposite said base and said retainer sheets; i. laminating a protective sheet, comprising a pressure-sensitive adhesive adhered to a backing, to said first release liner opposite said medical tape and to said second release liners opposite said conductive layers whereby each of said second release liners is secured to said first release liner; and, j. cutting said first release liner and said protective sheet transversely at predetermined locations along the length of said first release liner and protective sheet to form a strip containing a multiplicity of electrodes thereon.

Claim 9

A method of manufacturing biomedical electrodes comprising the steps of: a. cutting apertures at predetermined locations along the length of a first release liner; b. laminating a medical tape comprising a backing having a pressure-sensitive adhesive coating on at least one major surface thereof to the release liner whereby the adhesive-coated surface of said tape is adhered to the release liner; c. cutting said medical tape transversely between each of said apertures; d. laminating a series of retainer sheets having upper and lower major surfaces bound together by an edge surface to said medical tape through each of said apertures in said first release liner whereby said retainer sheets are adhered through said apertures to said adhesive-coated surface of said tape: e. cutting an aperture through said retainer sheets and on through said medical tape; f. locating an electrical terminal member comprising a base having upper and lower major surfaces and an upstanding post integral with said upper major surface of said base in each aperture in each retainer sheet and in the medical tape by extending said post of said terminal member through said aperture until said upper major surface of said base contacts the lower surface of said retainer sheet; g. laminating an ionically conductive layer to the lower surface of said each base and the lower surface of each retainer sheet through said apertures in said first release liner; h. laminating a second release liner to said conductive layers opposite said base and said retainer sheets; i. laminating a protective sheet, comprising a pressure-sensitive adhesive adhered to a backing, to said first release liner opposite said medical tape and to said second release liners opposite said conductive layers whereby each of said second release liners is secured to said first release liner; and, j. cutting said first release liner and said protective sheet transversely at predetermined locations along the length of said first release liner and protective sheet to form a strip containing a multiplicity of electrodes thereon.
