Abstract
Abstract The apparatus comprises at least a pair of electrodes supplied by an AC power supply, in contact therewith there are arranged, through suitable guide members, the tip and a middle portion of the syringe needle, the power supply to the electrodes being controlled by a switch which, as it is closed, provides an electric current effective to blunt and melt the needle which can not be reused.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
154 words
An apparatus for destroying injection syringe needles immediately after use, comprising two pairs of electrodes, supplied with an AC current, in contact therewith there are arranged, through guide means, a tip portion and a middle portion of a syringe needle, a switch for controlling electric power supplied to said two pairs of electrodes, said switch, as closed, providing an electrical current flow adapted to melt and blunt at least said tip portion of said syringe needle, each electrode of said two pairs of electrodes consisting of a small carbon block, a flexible reed member and two carbon rollers, said reed member being pivoted at one end thereof and having its other end arranged on a perpendicular line to said small carbon block, said carbon blocks having different heights so that top portions thereof are arranged at a given distance from a top shelf member provided with a plurality of holes for receiving syringe needles.
Claim 2
Independent Claim
154 words
An apparatus for destroying injection syringe needles immediately after use, comprising two pairs of electrodes, supplied with an AC current, in contact therewith there are arranged, through guide means, a tip portion and a middle portion of a syringe needle, a switch for controlling electric power supplied to said two pairs of electrodes, said switch, as closed, providing an electrical current flow adapted to melt and blunt at least said tip portion of said syringe needle, each electrode of said two pairs of electrodes consisting of a small carbon block, a flexible reed member and two carbon rollers, said reed member being pivoted at one end thereof and having its other end arranged on a perpendicular line to said small carbon block, said carbon blocks having different heights so that top portions thereof are arranged at a given distance from a top shelf member provided with a plurality of holes for receiving syringe needles.
Claim 3
Dependent Claim
25 words
An apparatus according to claim 1, wherein said carbon rollers are opposite horizontal-axis carbon roller pairs adapted to guide a downward stroke of said needles.
Claim 4
Dependent Claim
85 words
An apparatus according to claim 1, wherein said electrodes are supplied by electrical cables through a transformer coupled to an AC source by said switch, said apparatus further comprising a box-like round cross-section casing provided with supporting foot members and ventilation side slots and a closure cover affixed by a screw engaging in a threaded hole, said cover including a gripping handle and a first hole for perimetrically restraining an operation signalling lamp and second holes overlaying said roller pairs for receiving said syringe needles.
