A slotted guard for locking a needle in a shielded position as the needle is removed from a patient, and a guarded winged needle assembly including not only such a slotted, locking guard, but also a needle (with a winged hub attached thereto) slidably mounted within the guard. Preferably, the guard's slot has an angled portion so that when the hub and needle are fully retracted within the guard, the needle's tip will be oriented away from the slot. Also preferably, a piece of absorptive material is disposed in the guard to absorb any fluid dripping from the needle tip after the needle has been locked in its retracted position within the guard following an injection. An elongated anchor preferably protrudes outward from the guard so that the needle user may pull the wings of the hub (or a tube attached to the hub) in a conventional manner to retract the needle (and the hub and any tube attached to the needle) away from a patient while the user simultaneously presses the anchor member...

Claims

1. A guard slidably enclosing a sliding assembly comprising a needle and a winged needle hub having a first wing and a second wing, said first and second wings each having generally planar portions joined to said needle hub and extending outwardly therefrom, said planar portions having a major and a minor dimension, the major dimension being located parallel with the needle length, said guard comprising:

a hollow member having a first, distal end and a second, proximal end separated along a longitudinal axis, and a side wall defining a first slot and a second slot, wherein the first slot slidably receives the first wing planar portion and a second slot slidably receives the second wing planar portion, said first and second wings projecting through said first and second slots, said wings being exposed to the exterior of the hollow member along essentially the entire slot length to permit manual grasping of the wings; and
means for locking the sliding assembly in a retracted position in which the needle is enclosed by the hollow member after the sliding assembly has been translated along the longitudinal axis into the hollow member.

2. The guard of claim 1 which comprises an anchor member attached adjacent the first end of said hollow member and extending forwardly therefrom alongside of but spaced from said needle.

3. The guard of claim 2 in which said anchor member is substantially flexible, whereby it may be pressed against the skin of the patient when the needle is penetrating said skin.

4. The guard of claim 3 in which said hollow member comprises a first half-cylindrical portion and a second half-cylindrical portion attached together in hinged relation to permit assembly into a hollow member of generally cylindrical shape.

5. The guard of claim 4 in which said first and second wings are each flexible and substantially entirely planar in shape.

6. The guard of claim 1 in which said first and second wings are each flexible and substantially entirely planar in shape.

7. The guard of claim 1 in which said hollow member comprises a first half-cylindrical portion and a second half-cylindrical portion attached together in hinged relation to permit assembly into a hollow member of generally cylindrical shape.
