Abstract
Abstract The present invention provides a device and method for safely conveniently disposing of used needles. Several embodiments are provided. However, in a preferred embodiment, the device will be disposable and will comprise a container for accommodating the needle, said container having a flattened end and upper surface defining an elongated slit widened at one end, said slit shaped to accommodate the needle along its longitudinal axis; at least one resilient flap extending into said slit for retaining the needle in said container; a U-shaped opening disposed in said flattened end and continguous with said slit for separating the needle from a syringe; and a plurality of wings, flanking said slit and extending outwardly from said surface for protecting an individual using the device from accidental contact with the needle.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
54 words
A disposal device for a needle, comprising: a container for the needle, said container having at least one surface including an elongated slit shaped to accommodate the needle along its longitudinal axis; an end substantially perpendicular to said slitted surface; and a separator disposed in said end for separating the needle from a syringe.
Claim 2
Dependent Claim
54 words
A disposal device for a needle, comprising: a container for the needle, said container having at least one surface including an elongated slit shaped to accommodate the needle along its longitudinal axis; an end substantially perpendicular to said slitted surface; and a separator disposed in said end for separating the needle from a syringe.
Claim 3
Dependent Claim
12 words
The device of claim 1 wherein said surface is an upper surface.
Claim 4
Dependent Claim
12 words
The device of claim 1, wherein said container has a semicylindrical shape.
Claim 5
Dependent Claim
21 words
The device of claim 1, wherein said container is made of a material that is resistant to penetration by the needle.
Claim 6
Dependent Claim
28 words
A disposal device for a needle as recited in claim 1, further comprising: retainer means at least partially covering said slit for retaining the needle in said container.
Claim 7
Dependent Claim
22 words
The device of claim 1, wherein said means comprises a resilient flap, attached along one of its edges, extending adjacent the slit.
Claim 8
Dependent Claim
25 words
The device of claim 1, wherein: said separator includes a slot, contiguous with said slit, of such shape and size to accommodate a syringe neck.
Claim 9
Dependent Claim
30 words
The device of claim 1, wherein: said separator includes a slot, contiguous with said slit, of such shape and size to accommodate a syringe neck but not the needle hub.
Claim 10
Dependent Claim
12 words
The device of claim 7 wherein the slot is a U-shaped slot.
Claim 11
Dependent Claim
54 words
The device of claim 1, further comprising: a plate disposed within said container substantially parallel to said end, said plate defining a serrated opening adapted to frictionally grasp a needle hub mounted on a neck of a syringe assembly so as to prevent rotation of the needle hub when the syringe assembly is rotated.
Claim 12
Dependent Claim
36 words
A disposal device for a needle as recited in claim 1, further comprising: means, extending outwardly from the slitted surface of said container, for protecting an individual using the device from accidental contact with the needle.
Claim 13
Dependent Claim
45 words
A disposal device as recited in claim 1, further comprising: a plurality of wings, extending from said slitted surface so as to form at least a partial fence about said slitted surface, for protecting an individual using the device from accidental contact with the needle.
Claim 14
Dependent Claim
19 words
A disposal device for a needle as recited in claim 1, further comprising: a cap for sealing said device.
Claim 15
Dependent Claim
20 words
A disposal device for a needle as recited in claim 13, wherein said cap is pivotally mounted on said device.
Claim 16
Dependent Claim
126 words
A disposal device for a needle, comprising: (a) a container for accommodating the container having an upper surface and an end substantially perpendicular to said upper surface, said upper surface defining an elongated slit widened at one end, said slit shaped to accommodate the needle along its longitudinal axis; (b) at least one resilient flap at least partially covering said slit for retaining the needle in said container; (c) an opening disposed in said first end and contiguous with said slit for separating the needle from a syringe; and (d) a plurality of wings, extending outwardly from said upper surface so as to form at least a partial fence about said upper surface, for protecting an individual using the device from accidental contact with the needle.
Claim 17
Dependent Claim
126 words
A disposal device for a needle, comprising: (a) a container for accommodating the container having an upper surface and an end substantially perpendicular to said upper surface, said upper surface defining an elongated slit widened at one end, said slit shaped to accommodate the needle along its longitudinal axis; (b) at least one resilient flap at least partially covering said slit for retaining the needle in said container; (c) an opening disposed in said first end and contiguous with said slit for separating the needle from a syringe; and (d) a plurality of wings, extending outwardly from said upper surface so as to form at least a partial fence about said upper surface, for protecting an individual using the device from accidental contact with the needle.
Claim 18
Independent Claim
95 words
A method for disposing of a needle mounted on a syringe comprising the steps of: (a) providing a container having an upper surface defining an elongated slit shaped to accommodate the needle along its longitudinal axis; (b) positioning the needle above said slit so that the longitudinal axis of said needle is substantially parallel to the upper surface of said container; (c) forcing the positioned needle through said slit and into said container; (d) separating the needle from the syringe so that the needle is retained in the container; and (e) disposing of the container.
Claim 19
Independent Claim
95 words
A method for disposing of a needle mounted on a syringe comprising the steps of: (a) providing a container having an upper surface defining an elongated slit shaped to accommodate the needle along its longitudinal axis; (b) positioning the needle above said slit so that the longitudinal axis of said needle is substantially parallel to the upper surface of said container; (c) forcing the positioned needle through said slit and into said container; (d) separating the needle from the syringe so that the needle is retained in the container; and (e) disposing of the container.
Claim 20
Independent Claim
82 words
A method for inserting a needle into a needle disposal device comprising the steps of: a. providing a container having at least one surface defining an elongated slit; b. positioning the needle above said slit so that the longitudinal axis of said needle is substantially parallel to said slitted surface of said container; c. forcing the positioned needle through said slit and into said container; and d. separating the needle from the syringe so that the needle is retained in the container.
Claim 21
Independent Claim
82 words
A method for inserting a needle into a needle disposal device comprising the steps of: a. providing a container having at least one surface defining an elongated slit; b. positioning the needle above said slit so that the longitudinal axis of said needle is substantially parallel to said slitted surface of said container; c. forcing the positioned needle through said slit and into said container; and d. separating the needle from the syringe so that the needle is retained in the container.
