A receptacle includes a first recess for receiving the anterior end of the barrel of a conventional double ended needle blood collection tube holder to stabilize the holder during threaded disengagement of the needle. A post disposed within the recess includes a slot for receiving a rib of the double ended needle hub to prevent rotation of the hub while the holder is rotated to unthread the hub. Upon threaded disengagement, the needle drops into the receptacle, which drop may be augmented by a leaf spring. A second recess in the receptacle receives the collar of a guard supporting a translatable blood collection tube holder, which holder threadedly engages the hub of a double ended needle. A post within the recess can extend within the collar to engage with a slot a rib of the hub to prevent rotation of the double ended needle upon rotation of the guard to threadedly disengage the hub from the holder. Upon threaded disengagement, the double ended needle drops into the receptacle, which drop may be augmented by a leaf spring.
