ABSTRACT:
A combination stopper and shield closure for sealing the open end of an evacuated body fluid collection tube to retain the vacuum therein. The stopper is retained within a central aperture in the shield by an upper and lower flange, the upper flange having a convex surface for directing residue body fluid away from the center of the flange to reduce contamination. The closure also includes a gas-barrier bonded to the stopper and/or shield to increase the vacuum seal and cam followers extending from the bottom of the shield to interact with cams on the outer surface of the tube to facilitate closure twist-off. In addition, the closure includes flexible tabs around the bottom of the shield to prevent the tube/closure assembly from being pushed out of a needle holder during body fluid collection.
