Electrode for use with a template cap

摘要

An electrode attached to the straps of and use with a template cap in making neurophysiological measurements. The electrode is configured to allow the user to quickly and accurately slide an electrode needle at a shallow adjustable angle into the scalp of the patient. The base of each electrode attaches to the cap at locations where measurements are to be made. The base supports a ramp that may be snapped into a clip on the base for storage and then springs resiliently from the clip when released. The electrode needle is carried by a slidable holder secured to the ramp at its slot and is slid forward following that slot when driving the needle down and through a small hole in the base of the electrode to insert it into the patient's scalp at the appropriate depth and angle.
