Abstract
A needle protection assembly, adapted to protect a tip of a hypodermic needle, comprising a shield adapted, in a protected operative orientation of the needle protection assembly, to shield the tip of the hypodermic needle, a locking element including at least one slot, the slot including at least three surfaces corresponding to three operative orientations of the shield, at least one slot engaging element, functionally associated with the shield, the slot engaging element being disposed within the slot of the locking element and movable relative thereto, between the surfaces, so as to transition the shield between the three operative orientations, and at least one biasing element, adapted for axial biasing of the shield, wherein the three operative orientations include a storage operative orientation, an injection operative orientation, and a needle protection operative orientation.
Core Innovation
The invention provides a needle protection assembly adapted to protect a tip of a hypodermic needle. The assembly includes a shield that, in a protected operative orientation, shields the tip of the hypodermic needle. The shield is axially displaceable relative to a locking element, but not rotatable.
A locking element includes at least one slot having at least three surfaces corresponding to three operative orientations of the shield. The locking element has a base, and at least one slot engaging element is disposed within the slot and movable relative thereto between the surfaces. The slot engaging element transitions the shield between the three operative orientations and locks the shield in the protected operative orientation.
The assembly further includes at least one biasing element for axial biasing of the shield, applying axial force between the base and the slot engaging element. The biasing element includes a torsion force adapted for relative rotation between the slot engaging element and the locking element, where relative rotation allows transitioning between the storage operative orientation and the injection operative orientation. The three operative orientations include a storage operative orientation, an injection operative orientation, and a protected operative orientation.
Claims Coverage
The independent claim covers a needle protection assembly with three operative orientations (storage, injection, protected), where the shield is axially biased and transitioned and locked using a torsion-enabled slot and slot-engaging-element mechanism.
Three-orientation shield transition and locked protection
A needle protection assembly adapted to protect a tip of a hypodermic needle, comprising a shield adapted, in a protected operative orientation, to shield the tip; the shield is axially displaceable, but not rotatable, relative to the locking element, and the three operative orientations include a storage operative orientation, an injection operative orientation, and said protected operative orientation.
Slot with at least three surfaces corresponding to operative orientations
A locking element including at least one slot, said slot including at least three surfaces corresponding to three operative orientations of said shield; said locking element having a base; and at least one slot engaging element functionally associated with said shield and disposed within said slot, movable relative thereto between said surfaces to transition said shield between said three operative orientations and so as to lock said shield in said protected operative orientation.
Axial biasing with torsion for relative rotation-driven transitions
At least one biasing element adapted for axial biasing of said shield, the biasing element applying axial force between said base and said one slot engaging element, wherein said biasing element includes a torsion force adapted for relative rotation between said at least one slot engaging element and said locking element, and relative rotation between said at least one slot engaging element and said locking element allows transitioning between said storage operative orientation and said injection operative orientation.
The claim features a three-orientation shield, a slot and slot-engaging-element arrangement that transitions and locks the shield, and a biasing element that provides axial force and torsion for relative rotation.
