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.

First claim

What is claimed is:

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.

2. The blood collection tube holder of claim 1 , wherein the tube holder connector comprises a circumferentially extending ring that frictionally engages the forwardly facing end of the barrel.

3. The blood collection tube holder of claim 2 , wherein the slide member slidably engages the tube holder connector along an axis that is substantially transverse to a longitudinal axis through the retractable single needle.

4. The blood collection tube holder of claim 3 , wherein the transverse slot of the tube holder connector facilitates relative lateral movement of the retractable single needle to initiate retraction when oppositely directed manual pressure is applied to the tube holder connector and the slide member.

5. The blood collection tube holder of claim 1 , wherein the slide member comprises a needle support member that receives a spring to rearwardly bias a needle holder that secures in fixed relation the retractable single needle.

6. The blood collection tube holder of claim 1 , wherein the tube holder connector is frictionally engaged with an open front end of the barrel.

7. The blood collection tube holder of claim 1 , wherein the slide member and the tube holder connector slidably engage along a pair of cooperatively configured rails.

8. The blood collection tube holder of claim 1 , wherein the slide member and the tube holder connector comprise textured touch pads to facilitate application of oppositely directed manual pressure to laterally slide the slide member with respect to the tube holder connector and the barrel.

9. The blood collection tube holder of claim 1 , wherein the needle holder affixes the single needle in fixed relation to the needle holder.

10. The blood collection tube holder of claim 9 , wherein the needle holder is rearwardly biased by a spring received within a needle support member of the slide member.

11. The blood collection tube holder of claim 1 , wherein the barrel and the needle retraction cavity are in fluid communication via a reduced height portion of the partial wall.

12. The blood collection tube holder of claim 1 , wherein the venipuncture portion of the single needle is fully contained within the needle support member of the slide member when the needle assembly is retracted.

13. The blood collection tube holder of claim 12 , wherein a needle holder of the needle assembly and the fluid discharge portion of the single needle are received within the needle retraction cavity upon retraction of the needle assembly.

14. The blood collection tube holder of claim 1 , wherein a rearwardly facing end of the fluid discharge portion of the single needle retracts longitudinally beyond the partial wall.

15. 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.

16. The blood collection tube holder of claim 15 , wherein the venipuncture portion of the retractable single needle projects forwardly from the slide member prior to needle retraction.

17. The blood collection tube holder of claim 15 , wherein the venipuncture portion of the retractable single needle is covered by a selectively releasable needle cap prior to use.

18. The blood collection tube holder of claim 17 , wherein the selectively releasable needle cap further comprises a locking arm that prevents the slide member and the needle retraction cavity from becoming substantially aligned prematurely and thereby initiating needle retraction prior to use of the blood collection tube holder for drawing blood.

19. The blood collection tube holder of claim 15 , wherein the retractable single needle is affixed in a needle holder that is rearwardly biased by a spring received within a needle support member of the slide member, and wherein a rearwardly facing end of the fluid discharge portion of the retractable single needle retracts longitudinally beyond the reduced height portion of the partial wall.
