Needle base with plural needles for subcutaneously applying electric current

Claim 1

A needle base device for subcutaneously supplying electric current to the skin of a patient, comprising: a non-conductive member having a plurality of conductive needles mounted thereon for piercing a skin portion of the patient, said needles projecting from an outer surface of said non-conductive member; said non-conductive member comprising a convex plate-like member which protrudes outward toward the free ends of said needles at the central portion of said plate-like member, and said needles each perpendicularly projecting from said non-conductive plate-like member by substantially the same amount whereby more efficient and uniform cauterization is facilitated; said needles each having bottom ends embedded in said non-conductive member and being spaced from one another both laterally and horizontally by predetermined equal intervals or spacings, said needles having respective free ends opposite said embedded bottom ends; said needles each having a non-conductive covering over a portion of the length thereof which projects from said non-conductive member, said non-conductive covering extending from said non-conductive member to a portion of said respective needles intermediate the free and bottom ends thereof, said needles being uncovered over the remainder of their lengths between said intermediate portion and said free end thereof, the outer diameter of said non-conductive covering being the same as the outer diameter of the uncovered portions of said needles between said intermediate portions and said free ends thereof; and conductive means coupled to said non-conductive member and to said bottom ends of said needles for conductively connecting together said bottom ends of said needles for simultaneously supplying electrical energy to a plurality of said needles so as to enable simultaneous application of predetermined electric current to at least said plurality of said needles.
