Abstract

An elongated enclosed receptacle has an orifice formed in a first end thereof for receiving a cannula of a hypodermic syringe. A lever is pivotally mounted to the receptacle and has a blade mounted thereto that moves laterally across the orifice when the lever is rotated about its pivotal connection. A spring member urges the lever to a first position in which the blade does not overlay the orifice. A member is provided on a second end of the receptacle for receiving a loop which is attached to the lever so that the lever may be held against the force of the spring member in a second position in which the blade overlays the orifice and closes the receptacle.

Claims

1. A device for destroying hypodermic needles, comprising:

a receptacle having an orifice adapted to receive a cannula of a hypodermic syringe;

shear means associated with the orifice for shearing off the cannula and for covering the orifice; and

means for retaining the shear means in a position covering the orifice.

2. A device as described in claim 1, wherein the shear means comprises:

an arm mounted to the receptacle for relative movement between the arm and the receptacle; and

a blade mounted to the arm so that the blade moves laterally across the orifice when the arm is moved relative to the receptacle.

3. A device as described in claim 2, wherein the arm is a lever arm pivotally mounted to the receptacle.

4. A device for destroying hypodermic needles, comprising:

a receptacle having an orifice adapted to receive a cannula of a hypodermic syringe;

a lever arm pivotally mounted to the receptacle for relative movement between the arm and the receptacle;

a blade mounted to the lever arm so that the blade moves laterally across the orifice when the lever arm is moved relative to the receptacle; and

spring means for urging the lever arm to a position wherein the orifice is not covered by the blade.

5. A device as described in claim 4, additionally comprising:

means for retaining the lever arm in a position so that the blade covers the orifice and encloses the receptacle.

6. A device for destroying hypodermic needles which comprises:

a tubular receptacle having a closed end and an open end;

a base member inserted into the open end of the tubular receptacle and secured thereto, the base member having an orifice formed therethrough;

a lever arm pivotally mounted to the base member;

a blade member attached to the lever arm and disposed adjacent one end of the orifice in the base said blade member positioned to move laterally across the orifice when the lever arm is rotated;

spring means for urging the lever arm to a position wherein the blade member does not cover the orifice; and

means for retaining the lever arm in a second position wherein the arm is urged against the spring means and the blade member covers the orifice to close the receptacle, whereby a cannula inserted in the orifice while the lever arm is in the first position is sheared-off by the cooperation by the blade member and the base member when the lever arm is urged against the spring means and the blade member closes the receptacle to retain the sheared-off cannula within the receptacle and the retaining means secures the lever arm in the second position to assure that the receptacle remains closed so that the cannula may not be discharged from the receptacle.

7. A device for destroying hypodermic needles, comprising:

a receptacle having an orifice adapted to receive a cannula of a hypodermic syringe;

shear means associated with the orifice for shearing off a cannula and for covering the orifice;

spring means for urging the shear means to a first position in which the shear means does not cover the orifice; and

means for retaining the shear means against the force of the spring means in a second position covering the orifice.

8. A device for destroying hypodermic needles, comprising:

a receptacle having an orifice adapted to receive a cannula of a hypodermic syringe;

an arm mounted to the receptacle for relative movement between the arm and a receptacle;

a blade mounted to the arm so that the blade moves laterally across the orifice when the arm is moved relative to the receptacle; and

means for retaining the arm in a position so that the blade covers the orifice.

9. A device for destroying hypodermic needles, comprising:

an elongated receptacle having an orifice formed in a first end thereof for receiving a cannulA of a hypodermic syringe;

an arm having a first end pivotally mounted to the receptacle adjacent the first end of the receptacle and a second end movable from a first position remote from the receptacle to a second position adjacent the receptacle; and

a blade mounted to the arm so that the blade moves laterally across the orifice when the arm is pivoted from the first position to the second position.
