Abstract

An electrode belt made up of a strip of pile-backed foam on which a sheet of conductive silicone rubber is mounted by a snapped together fastener which clamps the sheet to the belt and compresses the sheet to form a suction cup when the belt is applied against the skin of the patient, especially when coated with conductive gel or water. The snap fastener provides means for convenient connection to the electrode leads for an apnea detector, an electro-cardiograph or a recorder for pneumogram or cardiogram signals which are transmitted through the conductive sheet and the fastener to the leads.

Claims

1. An electrode belt which comprises a belt of soft pliable material, a sheet of conductive, flexible, compliant, impervious material providing an electrode pad having opposite surfaces, one of which is disposed upon said belt and the other against the wearer when the belt is on the wearer, a fastener of conductive material having opposed plates disposed in clamping relationship with said pad and belt therebetween to form a depression in said pad of cup shape to provide a suction area between the skin of the wearer, the pad and one of said plates, said fastener having means providing an attachment for an electrode lead.

2. The electrode belt according to claim 1 wherein said fastener is a snap together fastener which includes said plates, a prong extending from one of said plates through said pad and said belt, a snap having a flange forming the other of said plates, said snap having an opening therein which receives said prong in press fit relationship, said snap providing said electrode lead attachment means.

3. The electrode belt according to claim 2 wherein a plurality of assemblies of said pads and snap together fasteners is disposed along said belt in spaced relationship with each other.

4. The electrode belt according to claim 1 wherein said sheet consists essentially of conductive silicone rubber.

5. The electrode belt according to claim 4 wherein said pad is of rectilinear shape about equal in width to the width of said belt.

6. The electrode belt according to claim 4 wherein said belt is a strip of pile backed foam material.

7. The electrode belt according to claim 6 further comprising a strip of hook type closure material attached to the pile backing on the outside of said belt to provide a buckle.

8. The electrode belt according to claim 1 wherein said fastener provides the exclusive connection between said pad and said belt.
