Abstract

A machine for destroying used syringes. A box includes a pair of bearing rods extending internally thereacross which slidably receive a carriage having a pair of spaced apart knives mounted thereto. A funnel mounted within the box is positioned beneath an aperture provided in the top wall of the box to receive the syringe to be destroyed. A pair of clamps mounted beneath the funnel releasably hold the syringe as the carriage moved by a linear actuator forces the knives to engage and sever in multiple locations the syringe. The clamps release the severed syringe allowing the parts to fall into a container removably positioned within the box.

Claims

1. The syringe destroying machine comprising:

an enclosure;

a holder in said enclosure sized to hold a syringe including a hollow main body and attached needle and positioned to locate said syringe entirely within said enclosure;

a carriage slidably mounted in said enclosure and moveable to and from said holder;

a knife mounted to said carriage and extending towards said holder;

electrically operated drive means connected to said carriage and operable to move said knife towards said holder to cut said syringe; and

,

a sliding door mounted to said enclosure and connected to said carriage being moveable over said holder to retain said syringe within said holder while being cut.

2. The syringe destroying machine comprising:

an enclosure;

a holder in said enclosure sized to hold a syringe including a hollow main body and attached needle and positioned to locate said syringe entirely within said enclosure;

a carriage slidably mounted in said enclosure and moveable to and from said holder;

a knife mounted to said carriage and extending towards said holder;

electrically operated drive means connected to said carriage and operable to move said knife towards said holder to cut said syringe; and

,

releasing means connected to said holder and operable to release said syringe once cut by said knife allowing said syringe to fall downwardly therefrom.

3. The machine of claim 2 and further comprising:

a removable container positioned beneath said holder to catch said syringe once cut.

4. The machine of claim 2 wherein said holder includes a pair of clamps pivotally mounted to said enclosure and connected to said carriage which open as said carriage moves towards said holder and said knife cuts said hollow main body and which close as said carriage moves away therefrom with said syringe falling downwardly therefrom.

5. A syringe destroying machine comprising:

a box;

a container removably associated with said box;

a bearing member mounted to said box and extending over said container;

a carriage slidably mounted to said bearing member and moveable at least partially across the width of said box, said box having a syringe receiving aperture through which a syringe may be inserted;

electrically operated drive means mounted to said box and connected to said carriage being operable to move said carriage back and forth;

closure means mounted to said box and operatively associated with said carriage to close said aperture when said carriage moves towards said syringe; and

,

severance means mounted to said carriage and operable to sever said syringe inserted through said aperture in more than one location as said carriage moves toward said syringe.

6. The machine of claim 5 wherein said severance means includes a multi-pointed knife edge mounted to said carriage and a straight needle engaging edge mounted to said carriage and spaced apart from said multi-pointed knife edge.

7. The machine of claim 6 wherein said closure means includes a door movably mounted within said enclosure and connected to said carriage.

8. The machine of claim 7 wherein said holder includes clamping means moveably mounted within said box and connected to said carriage being operable to hold said syringe upright and perpendicular to said multi-pointed edge and said needle engaging edge until said syringe is severed thereby and then operable to open and release said syringe as said carriage moves away therefrom allowing said syringe to drop into said container.

9. The machine of claim 8 wherein said holder includes a funnel mounted in said box and aligned with said aperture but being spaced therefrom to allow said door to move therebetween.

10. The machine of claim 9 and further comprising adjustment means associated with said clamping means and said carriage to allow adjustment of the opening and closing of said clamping means relative to the movement of said carriage.

11. The machine of claim 10 wherein said clamping means includes a pair of threaded rods connected to said carriage.

12. A machine for destroying the tubular main body and needle of a syringe comprising:

an enclosure;

a holder in said enclosure sized to hold a syringe with a hollow main body and attached needle with said holder positioned to locate said syringe entirely within said enclosure;

a carriage moveably mounted in said enclosure and moveable to and from said holder;

a knife mounted to said carriage and extending toward said holder;

electrically operated drive means connected to said carriage and operable to move said knife toward said holder to cut said syringe; and

a moveable door mounted to said enclosure and being moveable over said holder to retain said syringe within said holder while being cut.
