A needle free vacuumized blood collection device (20) includes a male connector having a valve element (34) disposed within the internal bore of the male connector (32) that opens or closes a flow passage into the blood collection vial (42). The valve element includes an activation arm (54) extending outwardly through the male connector that contacts a female connector (22) when the male and female connector are engaged. The activation arm shifts the valve element in the proximal direction to open a naturally open flow opening (74) in the valve element to permit flow into the vial. A spring device (60) biases the valve element to the non- flow configuration.

L'invention concerne un dispositif (20) de collecte de sang sous-vide sans aiguille comprenant un connecteur mâle présentant un élément vanne (34), disposé à l'intérieur d'un orifice interne du connecteur mâle (32) qui ouvre ou ferme un passage d'écoulement dans un flacon (42) de collecte de sang. L'élément de vanne comprend un bras d'activation (54) s'étendant à l'extérieur du connecteur mâle qui entre en contacte avec un connecteur femelle (22), lorsque le connecteur mâle et femelle sont enclenchés. Le bras d'activation décale l'élément vanne dans le sens proximal de manière à ouvrir un orifice d'écoulement (74) ouvert naturellement dans l'élément vanne ce qui permet l'écoulement dans le flacon. Un dispositif à ressorts (60) oriente l'élément de vanne dans une configuration de non écoulement.
