ABSTRACT:
An assembly for the collection of a patient's blood specimen comprises an elongate needle holder, a blood collection tube, and a cap closing the blood collection tube. The needle holder supports a blood extracting needle through a closed end thereof. The blood collection tube is insertable into the interior of the needle holder so as to collect blood. The cap has a membrane which is puncturable by the needle upon insertion of the blood collection tube into the interior of the needle holder. The cap includes a deflectable member extending therefrom for engagement with the cylindrical wall of the needle holder so as to frictionally resist longitudinal movement of the tube within the tube holder.
