ABSTRACT:
A blood collection tube is provided with a stopper adapted to be pierced by a needle cannula for introducing a sample of blood into the collection tube, and a valve disposed within the tube which allows blood to flow from the proximal end of the needle into the blood collection chamber of the tube but prevents the reflux of blood from the collection chamber to the patient.
