Abstract

A prehensile container is provided for demounting and storing used hypodermic needles and/or surgical blades pending their ultimate disposal. The same hand that holds the container can actuate the closure blade by finger force to clear an orifice for passage of a used hypodermic needle. When the end of the syringe to which the needle is affixed abuts the mouthpiece of the orifice, the finger force can be released to hold the needle between the edge of an aperture of the shutter blade and an edge of the orifice, so that the needle can be separated by withdrawal of the syringe with one hand while holding the container with the other. Another exertion of finger force will let the used needle drop into the container and a second release will restore the closed condition of the container. Internal baffles obstruct the exit of stored needles, to prevent an unauthorized person from extracting a needle from the container by opening the access orifice.

Claims

1. Portable and disposable prehensile container for demounting and storing used hypodermic needles and the like for their ultimate disposal, comprising:

a unitary container shell having an orifice for access of hypodermic needles to its interior;

a flat plate closure member for said orifice which member is mounted in the interior of said container shell beneath said orifice for movement permitting said closure member to be displaced between a first position in which it closes said orifice and a second position in which it leaves said orifice open to the interior of said container shell;

means for displacing said closure member from said first position to said second position by force exerted by a finger of a human hand by which said portable container is firmly held,

and means responsive to release of said human hand finger force for displacing said closure member away from said second position and towards said first position and thereby engaging, at least frictionally, a needle protruding through said orifice and thereby facilitating the demounting of said needle from a device on which it was mounted.

2. Prehensile container according to claim 1, wherein the periphery of said orifice is at least in part provided with indentations or crenelations.

3. Prehensile container according to claim 2, wherein said orifice is externally equipped with a frusto-conical mouthpiece for guiding a used hypodermic needle and for abutment of a syringe on which said needle is mounted.

4. Prehensile container according to claim 1, wherein said flat plate closure member is a single rigid blade.

5. Prehensile container according to claim 4, wherein said blade has an aperture of which the smallest dimension is at least equal to the diameter of said orifice.

6. Prehensile container according to claim 4, wherein said blade has an aperture of a shape selected from the group consisting of square, rectangular, circular, semrcircular, elliptical and semielliptical shapes.

7. Prehensile container according to claim 6, wherein the periphery of said aperture is at least in part provided with indentations or crenelations.

8. Prehensile container according to claim 1, wherein said means for displacing said closure member comprises a pushbutton equipped with means for connecting said pushbutton to said closure member, said means for displacing said closure member away from said second position and towards said first position serving also for return of said pushbutton to its rest position and said closure member to said first position.

9. Prehensile container according to claim 8, wherein said means for displacing said closure member towards said first position is a spring.

10. Prehensile container according to claim 1, wherein said container shell is equipped in its interior with baffle means opposing the return of a stored needle through said orifice of said container shell.

11. Prehensile container according to claim 1, wherein said baffle means is formed by at least one plate affixed at some of its edges to said container shell.

12. Prehensile container according to claim 11, wherein said baffle means is provided with an aperture for passage of a needle on its way into the interior of said container shell from said orifice of said container shell.

13. Prehensile container according to claim 12, wherein said aperture of said baffle means is provided with at least a partial tubular collar.

14. Portable and disposable prehensile container for demounting and storing detachable intrusive disposable parts of surgical and medical instruments in a manner avoiding contact with the person of attendant personnel, pending the ultimate disposal of the container and the parts stored therein, comprising:

a unitary container shell having an orifice for access of a said disposable intrusive part of a surgical or medical instrument for storage thereof in the interior of the container;

a flat plate closure device for said orifice which device is mounted in the interior of said container shell beneath said orifice and has an actuating control which is displaceable between a first position in which it closes said orifice and a second position in which it leaves said orifice open to the interior of said container shell;

means for displacing said actuating control from said first position to said second position by force exerted by a finger of a human hand by which said portable container is firmly held,

and means responsive to release of said human hand finger for displacing said actuating control away from said second position and towards said first position for engaging, at least frictionally, said disposable intrusive instrument part protruding through said orifice and thereby facilitating the demounting of said part from an instrument on which it was mounted.

15. Prehensile container according to claim 14, wherein said container shell is equipped in its interior with baffle means opposing the return from said orifice of a stored used part.

16. Portable and disposable prehensile container for demounting and storing used hypodermic needles and the like for their ultimate disposal, comprising:

a unitary container shell having an orifice for access of hypodermic needles to its interior;

a closure device having a plurality of flat blades crossing over each other, pivoted and commonly driven in the pattern of an iris diaphragm closure mounted in the interior of said container shell beneath said orifice and having an actuatable control movable between a first position in which said orifice is closed and a second position in which said orifice is left open to the interior of said container shell

means for displacing said actuation control of said closure from said first position to said second position by force exerted by a finger of a human hand by which said portable container is firmly held,

and means responsive to the release of said human hand finger force for displacing said actuation means away from said second position and towards said first position and thereby engaging, at least frictionally, a needle protruding through said orifice and thereby facilitating the demounting of said needle from a device on which it was mounted.
