A male Luer connector (200) that attaches to a female Luer connector to open a medical fluid flow channel between said connectors. The male connector has two internal valves (206, 208) and a vacuum-generating structure (212, 210). The two valves and the vacuum-~ generating structure are configured to draw back into the male connector any fluid residing on the interface between the connectors during their disengagement and to then seal the distal tip of the male connector. Both valves are opened/closed by a movable actuator plug (224) by contact with the front surface of the female connector. A resilient member (210) biases the male valves to the closed position and includes a variable internal volume (212) that creates the vacuum upon disengagement of the connectors. The male valves are timed to a particular sequence with the closing of an internal female connector valve so that the vacuum generated by the male connector will have the most fluid drawback effect.

La présente invention concerne un connecteur mâle Luer (200) qui est relié à un connecteur femelle Luer pour ouvrir un canal d'écoulement de fluide médical entre lesdits connecteurs. Le connecteur mâle possède deux soupapes internes (206, 208) et une structure de génération de vide (212, 210). Les deux soupapes et la structure de génération de vide sont configurées pour faire revenir dans le connecteur mâle tout fluide restant sur l'interface entre les connecteurs pendant leur disjonction et pour ensuite fermer de façon hermétique l'extrémité distale du connecteur mâle. Les deux soupapes sont ouvertes/fermées par un bouchon actionneur mobile (224) par contact avec les surfaces avant du connecteur femelle. Un membre élastique (210) sollicite les soupapes mâles vers la position fermée et comprend un volume interne variable (212) qui crée un vide lors de la disjonction des connecteurs. Les soupapes mâles sont réglées à une séquence spécifique correspondant à la fermeture d'une soupape de connecteur femelle interne de sorte que le vide généré par le connecteur mâle ait le plus grand effet de rappel de fluide.
