ABSTRACT:
A stopper for sealing an open end of a small internal diameter blood collection tube. The stopper includes a needle lead-in hole that guides the needle through an upper portion of the stopper to a penetration location at the bottom of the lead-in hole and to the open end of the small internal diameter tube. The stopper also includes a tube receiving chamber in its lower portion for receiving and sealing the open end of the tube. After the needle has penetrated the penetration location it passes through a resealable diaphragm section before entering the open end of the tube. The lead-in hole and tube receiving chamber both have beveled edges on their openings that aid in directing the needle and tube, respectively, into the stopper.
