ABSTRACT:
An apparatus for automatically evacuating blood aspiration tubes has an arraying table supporting a number of stoppered blood aspiration tubes which are to be evacuated, an air suction needle for evacuating air from inside the stoppered blood aspiration tubes, and an arm supporting the air suction needle on a needle rest and moving it horizontally and vertically over the arraying table. A drive control moves the air suction needle downward into the stopper of each of the blood aspiration tubes in turn, causes the needle to evacuate air from the tube, then withdraws the needle upward from the stopper. A presser is mounted to a lower part of the needle rest and presses the stopper during the upward movement of the needle in order to maintain the air-tight stoppering of the tube.
