1. A needle shield assembly comprising:
a shield portion configured to pivot from an open position in which a needle cannula of a needle assembly is exposed, to a closed needle protecting position in which at least a distal end of the needle cannula is received within the shield portion;
a hub connection portion; and
a bridge portion including a living hinge, the bridge portion joining the hub connection portion and the shield portion,
the hub connection portion comprising:
a receiving ring having a diameter sized to frictionally receive a hub of a needle assembly when the needle assembly is received by the receiving ring, the receiving ring further comprising the cylindrical wall extension which extends below the bottom surface of the flange, and
a flange extending from the receiving ring defining a top planar surface and a bottom surface,
the receiving ring is rotatable relative to the hub, the cylindrical wall extension provides a cylindrical receiving structure having an inner surface with splines that are configured to cooperate with hub splines on the hub of the needle assembly when the hub of the needle assembly is engaged with the cylindrical wall extension, wherein the splines are configured to engage and disengage with the hub splines as the hub is rotated with respect to the shield portion to a fixed position.
