Abstract
A syringe cap and needle assembly includes a needle retainer, a needle member secured within the needle retainer, and a cap. The needle member further includes an exterior needle end that extends outside of a forward end of the needle retainer. The cap is configured to slideably move with respect to the needle retainer between at least a first position and a second position. in the first position, the cap substantially surrounds the exterior needle end. In the first position and the second position, the cap substantially surrounds at least a portion of the needle retainer. in the second position, at least a portion of the exterior needle end is not surrounded by the cap.
Claims20
A syringe cap and needle apparatus comprising:
- a needle retainer;
- a needle member secured within the needle retainer, the needle member further comprising an exterior needle end that extends outside of a forward end of the needle retainer;
- and
- an inner cap comprising a substantially elongated outer body with a front end, a rear end and a longitudinal axis, wherein the inner cap is configured to substantially surround the exterior needle end and at least a portion of needle retainer;
- an outer cap comprising a substantially elongated outer body with a front end, a rear end and a longitudinal axis, wherein:
- the outer cap comprises a guide pin slideably postionable within at least one channel of the needle retainer, such that the outer cap is configured to slideably move with respect to the needle retainer between at least a first position and a second position;
- in the first position, the outer cap substantially surrounds the exterior needle end and the inner cap;
- in the first position and the second position, the outer cap substantially surrounds at least a portion of the needle retainer;
- and
- in the second position, at least a portion of the exterior needle end and at least a portion of the inner cap are not surrounded by the outer cap.
A syringe cap and needle apparatus comprising:
- a needle retainer;
- a needle member secured within the needle retainer, the needle member further comprising an exterior needle end that extends outside of a forward end of the needle retainer;
- and
- a cap, wherein:
- the cap is configured to slideably move with respect to the needle retainer between at least a first position and a second position;
- in the first position, the cap substantially surrounds the exterior needle end;
- in the first position and the second position, the cap substantially surrounds at least a portion of the needle retainer;
- and
- in the second position, at least a portion of the exterior needle end is not surrounded by the cap.
The syringe cap and needle apparatus of claim 10, wherein the cap is an outer cap, and the apparatus further comprises an inner cap that is substantially elongated, having a front end, a rear end and a longitudinal axis, wherein:
- the inner cap is configured to substantially surround the exterior needle end and at least a portion of the needle retainer and
- in the first position, the outer cap is configured to substantially surround at least a portion of the inner cap.
The syringe cap and needle apparatus of claim 11, wherein in the first position, the outer cap is configured to substantially surround the inner cap.
A method comprising:
- moving an outer needle cap from a first position to a second position, wherein:
- the outer cap is configured to slideably move with respect to a needle retainer between the first position and the second position,
- in the first position, the outer cap substantially surrounds an exterior needle end of a needle member secured within the needle retainer and the outer cap substantially surrounds an inner needle cap, and
- in the first position and the second position, the outer cap substantially surrounds at least a portion of the needle retainer;
- removing, after the outer cap is moved into the second position, the inner needle cap from a position affixed to the needle retainer, thereby exposing the exterior needle end;
- engaging a syringe apparatus operatively connected to the needle retainer to perform an injection;
- and
- after the injection, moving the outer cap from the second position back to the first position.
