Abstract

A hypodermic syringe destruction device wherein a cutting member and hammer member are positioned on a movable carrier within a housing. A fixed anvil is mounted within the housing, and an opening in the housing is arranged to permit the needle end of a hypodermic syringe to be inserted in an open region between the anvil and blade-hammer, with the movable carrier in a normal position. A solenoid is mechanically coupled to the carrier to move the blade through the syringe and hammer across the needle and anvil, whereby the needle region of the hypodermic syringe is separate from the syringe portion, and the needle is bent essentially 90°.

Claims

1. A hypodermic syringe destruction device for severing a syringe portion and bending a needle of a hypodermic syringe comprising:

a housing having an upper side and an opening in said upper side through which the needle end region of a hypodermic syringe may be generally vertically inserted downward, said opening having an axis with the syringe being insertable through said opening parallel to said axis;

a movable support within said housing and immediately below said upper side and supported by said housing for linear movement generally horizonally and transverse to said axis of said opening;

a blade attached to said movable support and lying in a generally horizontal plane and having an oblique edge which passes across and just under said opening in said upper side of said housing;

a hammer supported on said movable support and spaced below said blade, said hammer and support being generally L-shaped in cross section with said support forming a generally vertical wall facing the axis of said opening and with said hammer comprising a lower, generally horizontal plate extending outward from said generally vertical wall;

an anvil having a horizontal upper surface fixedly attached to the inside of said housing on the opposite side of said opening from said movable support and having a sloping surface which generally faces the vertical axis of said opening but slopes downward toward said vertical axis and having a generally horizontal lower surface at an elevation just above the upper surface of said lower plate of said hammer with said horizontal lower surface being spaced from the upper surface of said lower plate sufficient to bend the syringe needle therebetween, said anvil being opposite said support such that said anvil horizontal upper surface is coplanar with said blade lying in a horizontal plane and said sloping surface exgtends in a continuous manner from said horizontal upper surface to said horizontal lower surface;

operating means for selectively moving said movable support toward said anvil comprising a solenoid having a body region attached to said housing and a movable arm attached to said movable support, whereby, when a hypodermic syringe needle is inserted into said opening and said solenoid is operated, said L-shaped portion of said hammer bends the needle around said lower surface of said anvil, and a portion of the syringe holding said needle is supportable against the sloping surface of said anvil and is severed by said edge of said blade; and

a container positioned to receive the severed needle end region of a hypodermic syringe.
