1. A blood collection tube holder, comprising:
a body comprising a barrel and a needle retraction cavity, wherein the barrel and the needle retraction cavity are integrally formed, substantially parallel, and separated by a partial wall;
a tube holder connector coupled to a forwardly facing end of the barrel and comprising a transverse slot;
a slide member slidably engaging the tube holder connector; and
a rearwardly biased, retractable needle assembly comprising a needle holder and a single needle having a venipuncture portion extending forwardly from the needle holder, through the transverse slot of the tube holder connector, and projecting forwardly from the slide member and a fluid discharge portion extending rearwardly from the needle holder within the barrel;
wherein lateral sliding movement of the slide member with respect to the tube holder connector and the barrel causes the venipuncture portion to slide transversely through the transverse slot of the tube holder connector and the fluid discharge portion of the single needle to slide laterally past the partial wall until the single needle is aligned with the needle retraction cavity, which initiates retraction of the needle assembly within the needle retraction cavity.
