ABSTRACT:
An improved fluid collection tube assembly, particularly adapted for collecting blood or other biological fluid, includes a plastic collection tube having a forward end closed by a rubber diaphragm and an open rear end. A resilient piston member is slidably disposed within the tube in sealing engagement with the interior wall of the tube and is spaced forwardly from the open rear end. Prior to collecting a biological fluid from a patient, ambient air is in the space between the closed forward end of the tube and the piston member. When it is desired to collect a biological fluid from a patient, the piston is drawn rearwardly into the rear end of the tube to create a vacuum in the tube between the rubber diaphragm and the piston member.
