Abstract
A blood collection tube holder having a retractable single needle and a body comprising substantially parallel and laterally spaced apart barrel and needle retraction cavities separated by a partial wall that facilitates lateral movement of the single needle from the barrel cavity into alignment with the needle retraction cavity to initiate needle retraction. The barrel and a frontal attachment to the barrel are cooperatively configured to facilitate relative sliding movement between in a direction that is transverse to the longitudinal axis through the retractable single needle to initiate needle retraction.
Claims19
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.
A blood collection tube holder, comprising:
- a body comprising a barrel and an integrally formed needle retraction chamber;
- a tube holder connector coupled to the barrel;
- a slide member slidably engaging the tube holder connector;
- and
- a retractable single needle comprising a venipuncture portion and a fluid discharge portion;
- wherein the barrel comprises a barrel cavity, wherein the needle retraction chamber comprises a needle retraction cavity, and wherein the barrel cavity and the needle retraction cavity are disposed in a fixed, substantially parallel relationship and separated by a partial wall;
- and
- wherein the tube holder connector comprises a transverse slot configured to allow lateral sliding movement of the venipuncture portion of the retractable single needle therethrough while projecting forwardly from the slide member and the partial wall comprises a reduced height portion configured to simultaneously allow lateral sliding movement of the fluid discharge portion of the retractable single needle past the reduced height portion of the partial wall from a first position where the retractable single needle is coaxially aligned with the barrel cavity to a second position where the retractable single needle is coaxially aligned with the needle retraction cavity to initiate retraction of the retractable single needle within the needle retraction chamber.
