Hinged cap for needle device
First Claim
1. A hinged cap device for use with a syringe comprising:
- a base defining an interior cavity for mounting onto a tip;
a cap comprising a base wall, a first side wall, and a second side wall defining an open channel, wherein the cap is connected to the base by a living hinge, and wherein the cap is moveable from a ready position to an open position to expose a needle having a needle shaft and a needle tip, and from the open position to a secured position to prevent relative rotation between the cap and the base;
a first latching mechanism on the cap for engaging the needle, the first latching mechanism locatable on a first side of the needle shaft in the ready position and locatable on a second side of the needle shaft in the secured position;
wherein the needle is disengageable from the first latching mechanism in the ready position, and wherein the needle is not disengageable from the first latching mechanism in the secured position; and
a second latching mechanism on the cap for engaging the base to prevent relative rotation between the cap and the base when the cap is in the ready position, wherein the second latching mechanism comprises two spaced apart tabs extending in a proximal direction away from the needle tip;
wherein each tab of the two spaced apart tabs is adapted to abut a respective base tab located on the base; and
wherein the two spaced apart tabs are separable from the two respective base tabs on the base by moving the cap axially along a lengthwise axis of the needle relative to the base.

Abstract
A hinged cap device for use with a syringe includes a base defining an interior cavity for mounting onto a tip and a cap connected to the base by a living hinge. The cap is moveable from a ready position to an open position to expose a needle, and from the open position to a secured position to prevent relative rotation between the cap and the base. A first latching mechanism is on the cap for engaging the needle, the first latching mechanism locatable on a first side of the needle in the ready position and locatable on a second side of the needle in the secured position. The needle is disengageable from the first latching mechanism in the ready position, and the needle is not disengageable from the first latching mechanism in the secured position. The hinged cap device may also include a second latching mechanism to further prevent relative rotation between the cap and the base.

12. A hinged cap device for use with a syringe comprising:
-
a base defining a cavity to receive a syringe for mounting onto a tip of the syringe; a cap comprising a base wall, a first side wall, and a second side wall defining an open channel, the cap connected to the base by a living hinge and rotatable between a ready position and a secured position; a first latching mechanism on the cap for engaging a needle to prevent relative rotation between the cap and the base when the cap is in the secured position; and a second latching mechanism comprising at least one base tab protruding from the base and engaging at least one tab on the cap, wherein the at least one base tab is disengageable from the at least one tab by axially moving the cap along a lengthwise axis of the needle relative to the base. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A method for operating a hinged cap device, the hinged cap device comprising a base for supporting a needle, a cap connected to the base by a living hinge, a needle latching mechanism on the cap for engaging the base, the method comprising:
-
moving a cap axially along a lengthwise direction of a needle to distort the living hinge; rotating the cap radially outwardly relative to the needle to expose the needle; engaging the cap to the base in the cap open position; and
wherein the needle latching mechanism comprises a base tab protruding from the base and engaging at least one tab on the cap, wherein the base tab is disengageable from the at least one tab by axially moving the cap along a lengthwise axis of the needle relative to the base. - View Dependent Claims (21, 22)
