Cutting punches for destroying hypodermic syringes

Claim 1

An apparatus for destroying spent single-use hypodermic syringes for liquid medicaments each comprising a cannular needle having a point at one end and an enlarged section at the opposite end communicating with the barrel for the medicament, comprising a. a base, b. an annularly shaped cutter member mounted on said base provided with aligned grooves of different depth along a medial line of said cutter member adapted to support the syringe thereon along a line coincident with the axis of said grooves, with the needle adapted to rest in the shallower groove and the enlarged section in the deeper groove, c. a cylindrical cutting punch provided with cutting edges at the lower end thereof for interengagement with the inner diameter of said cutter member, and d. means for moving said cutting punch into said cutter member with great force to sever said needle resting in said firstmentioned groove and said enlarged section resting in said deeper groove.

Claim 2

An apparatus for destroying spent single-use hypodermic syringes for liquid medicaments each comprising a cannular needle having a point at one end and an enlarged section at the opposite end communicating with the barrel for the medicament, comprising a. a base, b. an annularly shaped cutter member mounted on said base provided with aligned grooves of different depth along a medial line of said cutter member adapted to support the syringe thereon along a line coincident with the axis of said grooves, with the needle adapted to rest in the shallower groove and the enlarged section in the deeper groove, c. a cylindrical cutting punch provided with cutting edges at the lower end thereof for interengagement with the inner diameter of said cutter member, and d. means for moving said cutting punch into said cutter member with great force to sever said needle resting in said firstmentioned groove and said enlarged section resting in said deeper groove.

Claim 9

An apparatus for destroying spent single-use hypodermic syringes each comprising a cannular needle having a point at one end and a hub at the opposite end connected to the barrel for the medicament, comprising a. a tool standard having a horizontal base extending forwardly therefrom and an overhang portion spaced from and overlying said base, b. an annularly-shaped female die element seated on said base at the forward portion thereof, provided with a cutting edge at the top of the interior thereof, of an internal diameter to support the hypodermic syringe for severance at the needle and hub portions thereof, c. a vertically reciprocable plunger in said overhang portion of said standard terminating in cutting edge portions at the lower end thereof spaced at least at diametrally opposed parts of said lower end, d. spring means connected with said plunger to bias said lower end of said plunger into spaced relation with respect to said cutting edge of the female die element, e. manual means pivotally mounted on said overhang portion of said standard above the upper end of said plunger and including eccentric means cooperating with the latter to depress said plunger, with great mechanical advantage, into cooperative cutting engagement with said female die element, whereby the cutting edge at the inner diametral part of said plunger is adapted to sever the cannular needle while the cutting edge at the outer diametral part of said plunger is adapted to sever a thicker portion of the hypodermic syringe which is adapted to be disposed horizontally on said female die element for destruction, with the barrel of the syringe extending forwardly and the cannular needle extending rearwardly beyond said female die element, and f. a slidable drawer in said horizontal base below said female die element for collecting the severed needle and hub portions for ultimate disposal.

Claim 10

An apparatus for destroying spent single-use hypodermic syringes each comprising a cannular needle having a point at one end and a hub at the opposite end connected to the barrel for the medicament, comprising a. a tool standard having a horizontal base extending forwardly therefrom and an overhang portion spaced from and overlying said base, b. an annularly-shaped female die element seated on said base at the forward portion thereof, provided with a cutting edge at the top of the interior thereof, of an internal diameter to support the hypodermic syringe for severance at the needle and hub portions thereof, c. a vertically reciprocable plunger in said overhang portion of said standard terminating in cutting edge portions at the lower end thereof spaced at least at diametrally opposed parts of said lower end, d. spring means connected with said plunger to bias said lower end of said plunger into spaced relation with respect to said cutting edge of the female die element, e. manual means pivotally mounted on said overhang portion of said standard above the upper end of said plunger and including eccentric means cooperating with the latter to depress said plunger, with great mechanical advantage, into cooperative cutting engagement with said female die element, whereby the cutting edge at the inner diametral part of said plunger is adapted to sever the cannular needle while the cutting edge at the outer diametral part of said plunger is adapted to sever a thicker portion of the hypodermic syringe which is adapted to be disposed horizontally on said female die element for destruction, with the barrel of the syringe extending forwardly and the cannular needle extending rearwardly beyond said female die element, and f. a slidable drawer in said horizontal base below said female die element for collecting the severed needle and hub portions for ultimate disposal.
