US 8,412,303 B2 · Electrode for use with a template cap

Abstract

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.

Dependent claims

An electrode for neurophysiological measurements and for use with a template cap, said electrode comprising:

(a) a base having a proximal end and a distal end, said base having a slot formed therein;
(b) a ramp having a proximal end and a distal end, said distal end of said ramp being attached near said distal end of said base, said ramp having a slot running between said proximal end of said ramp and said distal end of said ramp;
(c) a holder carried by said ramp in said slot of said ramp, said holder having a needle housing portion and a thumb drive portion;
and
(d) a needle having a proximal end and a distal end, said proximal end carried by said needle housing portion and said needle can be moved by pressing on said thumb drive portion and pushing said thumb drive portion from said proximal end to said distal end of said slot of said ramp thereby causing said distal end of said needle to pass from said base through said slot in said base.

A template cap with electrodes for neurophysiological measurements, said template cap comprising:

(a) straps secured together to form a cap for use on the head of a patient to undergo neurophysiological measurements;
and
(b) plural electrodes prepositioned and secured to said straps, each electrode of said plural electrodes having
(i) a base having a proximal end and a distal end, said base having a slot formed therein;
(ii) a ramp having a proximal end and a distal end, said distal end of said ramp being attached near said distal end of said base, said ramp having a slot running between said proximal end of said ramp and said distal end of said ramp;
(iii) a holder carried by said ramp in said slot of said ramp, said holder having a needle housing portion and a thumb drive portion;
and
(iv) a needle having a proximal end and a distal end, said proximal end carried by said needle housing portion and said needle oriented parallel to said slot so that said needle can be moved by pressing on said thumb drive portion and pushing said thumb drive portion from said proximal end to said distal end of said slot of said ramp thereby causing said distal end of said needle to pass through said slot in said base.
