ABSTRACT:
A holder for evacuated test tubes used for blood or bodily fluids having rubber stoppers includes a case having a plurality of channels. The test tubes ride in channels supporting themselves or supported by the flanges of the rubber stoppers. A spring or other mechanism to push or pull the test tubes forwardly along the channels to a forwardmost position is used. At the forwardmost position a separate flap is present which includes a hole aligned with each of the rubber stoppers in the test tubes in this forwardmost position. Thus, when blood or other bodily fluids are transferred from a hypodermic needle-tipped syringe, the needle is pushed through the hole in the flap directly into the rubber stopper of the test tube. When the fluid is transferred, the needle is removed, and the flap can be lifted to remove the test tube which can then be sent to the testing lab.
