A connector assembly is provided for efficient flow of liquid into and/or out of a vial, such as a vial containing a lyophilized drug The connector assembly includes a spike slidably mounted in the open top of the vial. The connector assembly further includes a stopper sealingly engaged in the open top of the vial and slidably moveable in response to the axially movement of the spike. Thus, movement of the spike relative to the vial will move the stopper into or out of sealing engagement with the vial. The connector assembly further includes a spring for generating a small amount of axial movement of the spike after the stopper has been moved into the opened position in the vial. Movement of the spike generated by the spring will cause a sufficient change in pressure to overcome surface tension and initiate an efficient flow of fluid into or out of the vial.

Un ensemble-raccord est prévu pour permettre un écoulement efficace de liquide vers l'intérieur ou l'extérieur d'une fiole qui contient, par exemple, un médicament lyophilisé. Il comporte un perforateur monté de façon coulissante dans la partie supérieure de la fiole. De plus, il comprend un joint s'engageant de façon étanche dans la partie supérieure de la fiole et pouvant coulisser en réponse au déplacement axial du perforateur. Le déplacement du perforateur par rapport à la fiole fera donc bouger le joint, ce qui permettra d'ouvrir la fiole ou de la refermer de façon étanche. En outre, l'ensemble-raccord comprend un ressort permettant de générer un léger déplacement axial du perforateur, une fois le joint placé en position ouverte dans la fiole. Le déplacement du perforateur au moyen du ressort entraînera une modification suffisante de la pression pour surmonter la tension superficielle et amorcer un écoulement efficace de liquide vers l'intérieur ou l'extérieur de la fiole.
