ABSTRACT:
A blood collection assembly is provided for blood collection tubes, and more particularly for evacuated blood collection tubes, whereby the potential exposure of laboratory technicians or hospital personnel to potentially infectious blood specimens is reduced. The device consists of a cap which is configured to be placed over and fitted onto the rubber stopper of an evacuated collection tube. The top surface of the cap includes a centrally located bore section which is surrounded by a downwardly directed retaining ring to prevent accidental exposure of the user to the upper flange portion of the stopper wherein the user is protected from exposure to the contaminated bottom surface of the stopper as the cap and stopper are removed from the collection tube.
