Disposable electrodes for electromyography (EMG) and nerve conduction velocity (NCV) and kit containing same

摘要

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.
