Biomedical electrode having a secured one-piece conductive terminal
First Claim
Patent Images
1. A biomedical electrode comprising:
- an electrolytic gel layer having first and second sides wherein said first side is adapted to contact a patient;
a conductive terminal having a base portion integrally joined to a stud member, said base portion being mounted to said second side of said gel layer;
an anchoring patch having a first opening correspondingly sized with said stud member of said terminal, said anchoring patch being mounted over said terminal such that said stud member protrudes through said first opening and said base portion is held against said second side of said gel layer, said anchoring patch being formed of a porous foam material having sufficient porosity such that said anchoring patch is securable to said second side of said gel layer;
a top layer having first and second sides and a second opening correspondingly sized with said stud member of said terminal, wherein said second side of said top layer has a patient-contact adhesive coating, said top layer being adhesively mounted onto said anchoring patch such that said stud member protrudes through said second opening and the periphery of said second side is capable of being secured to said patient; and
a conductive cap portion attached over said stud member and positioned over said second opening on said first side of said top layer.

Abstract
A disposable biomedical electrode having a one-piece terminal secured therein without washers, retaining rings or other securement means is provided. The electrode also includes an electrolytic gel which exhibits greater patient comfort without any decrease in electrical performance. The gel layer is preferably a hydrogel material formed from an aqueous mixture of polyhydric alcohol, aliphatic diisocyanate terminated prepolymer, polyethylene oxide based polyamine, and sodium chloride.
