Abstract
An apparatus and method of automatically and safely removing a needle from a syringe assembly while retaining a syringe hub as part of the syringe assembly is generally described. A needle containment device is provided, which may include a needle handling apparatus and a shutter mechanism assembly. The needle handling apparatus is configured for receiving at least a portion of a syringe assembly including at least a needle and a syringe hub, wherein a first clamping mechanism is configured to clamp the syringe hub and a second clamping mechanism is configured to clamp the needle, so that the needle is safely and automatically removed from the syringe hub.
Claims19
A method of automatically removing a needle from a syringe hub and depositing the needle into a needle handling device, the method comprising:
- inserting at least a portion of a syringe assembly into the needle handling device, the syringe assembly comprising the needle and the syringe hub;
- activating the needle handling device to automatically remove the needle from the syringe hub;
- and
- depositing the needle into a removable sharps container while the syringe hub remains attached to the syringe assembly.
A reusable needle handling device configured for receiving at least a portion of a syringe assembly, the syringe assembly including at least a needle threadingly connected to a syringe hub, the reusable needle handling device comprising:
- a first clamping mechanism to clamp the syringe hub;
- and
- a second clamping mechanism including a shutter mechanism, wherein the shutter mechanism includes at least a gear plate, a backing plate, and a plurality of arms, wherein each of the arms is positioned between and pivotably connected to each of the gear plate and the backing plate and the gear plate is rotatable relative to the backing plate, wherein
- the plurality of arms are configured for clamping the needle and unscrewing the needle from the syringe hub when the gear plate is rotated relative to the backing plate.
A reusable needle handling device comprising:
- a removable protective sleeve configured for receiving at least a portion of a syringe assembly, wherein the syringe assembly comprises a needle and a syringe hub, the needle being screwed onto the syringe hub;
- a first clamping mechanism to clamp the syringe hub;
- a second clamping mechanism to clamp the needle and to automatically remove the needle from the syringe hub;
- and
- a sensor to automatically detect an insertion of the needle into the needle handling device and in response to automatically detecting the insertion, automatically activating the second clamping mechanism to clamp the needle and remove the needle from the syringe hub.
