Abstract:
1. A reconstitution device, comprising: a one-piece support; a hollow needle, pointed at both ends and fixed on said support, said support defining two coaxial sockets enclosing each end of said needle, a first one of said sockets being adapted to receive a plugged mouth of a vial and a second one of said sockets being adapted to receive a tip of an injection tube of a flexible bag, so that perforating a plug of a vial and a tip of an injection tube places a vial in communication with a flexible bag via said needle, said first one of said sockets including a continuous or discontinuous flange projecting inwardly adjacent an inlet opening of said first one of said sockets and at least one resiliently retractable projection within said first one of said sockets and spaced apart from said flange that together with said flange engage a tip of an injection tube in a first stable position in which said device is secured to a flexible bag without said needle being in contact with a tip of an injection tube, said first one of said sockets being slidably mounted on a tip of an injection tube so as to pass, by simple sinking of the device against a tip of an injection tube, from said first stable position to a second stable position, said needle piercing a tip of an injection tube in said second stable position.
