Abstract:
1. A blood collection assembly, comprising: a first sub-assembly comprising, a hub comprising, a flash indicator, having a distal end and a proximal end engageable with a specimen collection container, a cannula extending between a patient end and a non-patient end, defining a cannula interior, the patient end of the cannula projecting at least partially from the distal end of the hub, the cannula interior in fluid communication with the flash indicator, a cannula shield removably engaged with the distal end of the hub and shielding at least the patient end of the cannula, the cannula shield comprising a safety shield engagement, and a pivoting safety shield engaged with a portion of the hub comprising at least one locking tab, the pivoting safety shield transitionable from a first position in which the locking tab is releasably engaged with the safety shield engagement of the cannula shield wherein at least one of the locking tab and/or the safety shield engagement are configured such that engagement therebetween resists application of axial force to the cannula shield and retains the cannula shield about the cannula, to a second position, in which the locking tab is disengaged from the safety shield engagement and the patient end is exposed, to a third position in which the patient end is shielded by at least a portion of the pivoting safety shield and the locking tab is fixedly locked with a portion of the hub; wherein the safety shield engagement is a ridge projecting upwardly from an outer surface of the cannula shield and extending along at least a portion of a longitudinal axis of the cannula shield, and at least a portion of the ridge is engageable with at least a portion of the locking tab in a detent arrangement to restrain the pivoting safety shield with the cannula shield, wherein a second sub-assembly comprising a specimen collection container holder having an interior through which a specimen collection container may be engaged with the proximal end of the hub, and wherein the first sub-assembly further comprises a first portion for press-fit engagement with the second sub-assembly, and the second sub-assembly comprises a corresponding second portion for press-fit engagement with the first sub-assembly.
