Abstract
A shieldable unit dose needle assembly including a unit dose needle, a shield in pivotal engagement with respect to the needle, and a collar providing pivotal engagement between the needle and the shield. The shield is pivotally movable between a retracted position and a shielded position in which a portion of the shield encompasses the unit dose needle for safety purposes. The collar further includes a handle for holding the needle assembly during use, which handle may include a profile for accommodating a user's fingers.

A shieldable unit dose needle assembly for administering a unit dose of a vaccine comprising:
- a unit dose needle having a handle end and a prong end configured to hold a unit dose of a vaccine;
- a shield in pivotal engagement with respect to said unit dose needle and pivotally movable between a retracted position pivotally spaced from said prong end of said unit dose needle and a shielded position encompassing said prong end of said unit dose needle;
- a collar including a needle end, said unit dose needle extending from said needle end of said collar, said collar providing for pivotal movement of said shield between said retracted position and said shielded position;
- and
- a handle extending from said collar opposite said needle end.
A shieldable needle assembly for administering a unit dose of a vaccine comprising:
- a) a unit dose needle assembly comprising:
- i) a hub including a needle end and an engagement end;
- and
- ii) a unit dose needle including a prong end configured to hold a unit dose of a vaccine, said unit dose needle extending from the needle end of the hub;
- and
- b) a shield assembly comprising:
- i) a collar including a needle engagement end and a handle end;
- ii) a shield including a pair of longitudinally extending sidewalls defining a longitudinal opening, said shield pivotably connected to said collar;
- and
- iii) a handle extending from the handle end of said collar, wherein the needle engagement end of the collar and the engagement end of the hub include corresponding structure for attachment therebetween, and wherein the shield is pivotal with respect to the unit dose needle between a retracted position pivotally spaced from the prong end of the unit dose needle and a shielded position with the prong end of the unit dose needle encompassed within the longitudinal opening.
A shieldable, single use unit dose needle assembly for administering a unit dose of a vaccine comprising:
- a unit dose needle having a handle end and a prong end configured to hold a unit dose of a vaccine;
- a fitting capable of receiving the unit dose needle, said fitting including a hinge having a first end and a second end, the first end being attached to an outer surface of the fitting;
- an elongated housing attached to the second end of the hinge, the elongated housing being pivotal and capable of enclosing the unit dose needle, the housing comprising a longitudinal slot for receiving the unit dose needle as the housing is pivoted to enclose the unit dose needle and at least one elongated door member hingedly attached to the housing extending across the longitudinal slot over substantially the entire length of the longitudinal slot, wherein the door member is biased to close the longitudinal slot after a needle has entered the housing through the longitudinal slot;
- and
- a handle extending from a handle end of said fitting.
A shieldable unit dose needle assembly for administering a unit dose of a vaccine comprising:
- a collar having opposing first and second ends;
- a unit dose needle having a first pronged end and a second end, said pronged end of said unit dose needle extending from said first end of said collar;
- and
- a housing pivotable from said collar to a position in alignment with said unit dose needle for enveloping said unit dose needle.
