Abstract

An integral medical electrode for monitoring and diagnostic applications which includes a fusible conductive substrate to which are fused the other components, such as the conductor, of the electrode. The fusible conductive substrate includes a non-conductive carrier providing a support layer; a conductive additive; and a sealant functioning as a fusible bonding medium to integrate the non-conductive carrier, the conductive additive, and the other components of the electrode.

Claims

1. An integral medical electrode adapted to contact the skin of a patient and comprising:

a conductor transmitting bio-electric signals between the skin and the conductor; and

a conductive substrate having;

(a) a non-conductive carrier providing a support layer,

(b) a conductive additive, and

(c) a sealant sealing, fusing, and bonding said non-conductive carrier, said conductive additive, and said conductor into said integral medical electrode.

2. The electrode as claimed in claim 1 wherein said sealant is a thermoplastic.

3. The electrode as claimed in claim 2 wherein said thermoplastic sealant is selected from the group consisting of polyolefins, polyurethane elastomers, nylons, plasticized polyvinyl chloride, copolymers of ethylene and acrylic acid, and polymer blends.

4. The electrode as claimed in claim 3 wherein said thermoplastic sealant is a low density polyethylene base coated with an ethylene and acrylic acid copolymer.

5. The electrode as claimed in claim 1 wherein said sealant has an inducer selected from the group consisting of heat and chemical inducers adapted to temporarily convert said sealant from a solid state into fluidic form.

6. The electrode as claimed in claim 1 wherein said conductive additive is selected from the group consisting of metals, metal alloys, metal-metal salt combinations, and carbon.

7. The electrode as claimed in claim 1 wherein said non-conductive carrier is selected from the group consisting of paper and polymer films.

9. The electrode as claimed in claim 1 wherein said electrode is adapted for monitoring and diagnostic applications and said conductor receives and transmits bio-electric signals from the skin, said electrode further comprising a stud sealed, fused, and bonded to said substrate by said sealant and adapted to engage a female snap connector electrically interconnected through a lead to a monitor, said substrate forming an electrical path from said conductor to said stud.

10. The electrode as claimed in claim 9 further comprising a non-conductive support layer sealed, fused, and bonded to said substrate by said sealant and supporting said substrate, said conductor, and said stud.

11. The electrode as claimed in claim 10 wherein said support layer has an aperture and said conductor substantially fills said aperture to assure contact between said conductor and the skin.

12. The electrode as claimed in claim 11 further comprising an adhesive, said support layer having a bottom surface to which said adhesive is attached to hold said conductor against the skin.

13. The electrode as claimed in claim 12 further comprising a liner covering said support layer and said conductor when said electrode is not in use.

14. The electrode as claimed in claim 12 further comprising a conductive adhesive, said support layer and said conductor each having a bottom surface to which said conductive adhesive is attached to hold said conductor in electrical contact against the skin.

15. The electrode as claimed in claim 14 further comprising a liner covering said conductive adhesive when said electrode is not in use.

16. An integral medical electrode adapted to contact the skin of a patient, adapted for monitoring and diagnostic applications, and comprising:
