US Patent:

52556778, Oct 26, 1993

Filed:

Nov 2, 1992

Appl. No.:

7/969499

Inventors:

Alan J. Schaefer - Spring Valley NY
Arthur Blumenfeld - Brewster NY
Finn Pedersen - Stenlose, DK
Carsten Stabell - Bronshoj, DK

Assignee:

Vickers PLC - London

International Classification:

A61B 504
A61B 50492

US Classification:

128640

Abstract:

A disposable electrode for use in electromyography and/or nerve conduction velocity testing has a tab for connection to a cable connector and is laminated of a plurality of layers including first and second outer layers. The first layer is a backing member with exposed adhesive, a hydrogel layer intermediate the outer layers and a conductive foil layer between the hydrogel layer and the second outer layer. The electrode may be a disc electrode, a ground electrode or an elongated flexible digital ring electrode. The disc electrode includes two identical disc electrode elements having circular portions separably joined to each other at a central portion and the tab of each element is remote from the central portion. A kit contains a plurality of disposable electrodes packaged in a blister pack, the packaged electrodes including a plurality of such disc electrodes, a plurality of such ground electrodes and a plurality of such elongated flexible digital ring electrodes.
