ONE-WAY EVACUATED TUBE STOPPER ABSTRACT OF THE DISCLOSURE A stopper for an evacuated tube with an open end for collecting fluid such as blood samples. The stopper includes a plug adapted to be mounted in the opening in the tube so as to normally seal the tube. The plug permits access of a fluid sample needle therethrough into fluid communication with the reduced pressure interior of the tube so that fluid is collected in the tube from the needle. A check valve is on the plug to automatic- ally open when the needle is inserted through the plug and sub- jected to the reduced pressure in the tube and to automatically close when subjected to a predetermined amount of pressure from within the tube such as that caused by backflow thereby prevent- ing any fluid passing into the needle from the tube. The check valve includes a chamber which can be used as a reagent holder prior to tube use.
