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.
A disposable elongate flexible electrode having a relatively narrow width to provide in use a wraparound digital ring electrode for electromyography (EMG) and/or nerve conduction velocity (NCV) testing, said electrode having a connector end and a rear end, said electrode laminated of a plurality of layers arrangeable on a backing sheet, and orientable from a patient's skin outward to comprise in combination: a first layer comprising hydrogel conductive adhesive and a non-conductive sealing foil, the sealing foil positioned short of the connector end and the adhesive contiguous therewith and extending to the rear end of the electrode, a second layer comprising conductive foil on the first layer and provided with a conducive tab at the connector end and extending beyond the sealing foil; the sealing foil extending across the narrow width of the electrode and wholly bordering thereacross on one side the conductive foil and having a rearward end wholly bordering thereacross the hydrogel conductive adhesive. whereby electricity communicates with the patients via the hydrogel conductive adhesive and via the conductive foil and via the conductive tab past the non-conductive sealing foil.
