Abstract
A blood collection tube holder embodying two coaxially alignable needles, the first needle being a forwardly facing venipuncture needle and the second needle being a rearwardly facing fluid discharge needle. The first and second needles are satisfactorily supported by a frontal attachment and body, respectively, that are disposed in relative sliding engagement along an interface that is transverse to the first and second needle and that extends at least from the second needle to an opening into a needle retraction chamber that projects rearwardly from the body. The subject device is configured to receive and support a conventional blood collection tube of the type used to collect blood samples.
Claims18
A blood collection tube holder comprising:
- a body further comprising a rearwardly facing fluid discharge needle and a needle retraction chamber laterally spaced apart from the fluid discharge needle;
- and
- a frontal attachment disposed in transverse sliding relation to the body, the frontal attachment comprising a needle retraction mechanism further comprising a forwardly projecting venipuncture needle that is coaxially aligned with the rearwardly facing fluid discharge needle when the body is disposed in a first position relative to the frontal attachment and that is coaxially aligned with and retractable into the needle retraction chamber when the body is repositioned laterally to a second position relative to the frontal attachment.
