An improved needle electrode for use with a hypodermic syringe attachment which includes a needle member, a conductor wire directly attached to an uninsulated portion of the needle member, insulating material formed around at least a portion of the needle member and the conductor wire thereby to form a handle which has a smooth external configuration preferably of ogival shape for easy gripping and dexterous manipulation by an operator. The hypodermic syringe attachment is capable of connection to the handle and an electric lead is capable of connection to the conductor wire. The insulating material is directly formed, as by molding, around the needle member and the conductor wire.

Needle electrode for use with hypodermic syringe attachment

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.
