Patent ID: 8016809

Claim:
A liquid drug delivery device for use with a syringe having a syringe tip ending at a widened distal tip having an outer diameter D 1 and a length L 1 , and a medicinal vial with a rubber stopper, the device comprising: (a) a housing having a longitudinal axis, a syringe port and a drug administration port co-directional with said longitudinal axis for correspondingly receiving the syringe and administrating the liquid drug, and a tubular vial adapter port intermediate said syringe port and said drug administration port; (b) a flow control member rotatably supported in said vial adapter port about an axis of rotation generally perpendicular to said longitudinal axis, said flow control member including an L-shaped mixing flow channel with a radial section for flow communication with said syringe port in a mixing flow control position and an axial section, said flow control member including a peripheral semi-circular administration flow channel for enabling flow communication between said syringe port and said drug administration port in a subsequent administration flow control position, (c) a vial adapter for telescopically receiving a vial and including an upright tubular male connector and a downward depending tubular cannula for extending into the vial and in flow communication with said male connector, said vial adapter being initially coupled to said housing for sealing insertion of said male connector in said axial section and being rotationally detachable from said housing whereupon rotation of said vial adapter relative to said housing simultaneously rotates said flow control member from said mixing flow control position to said administration flow control position, characterized in said syringe port including an inlet port having an elastomeric tubular sealing member for sealed fluid communication with the syringe and a single use locking mechanism having at least two opposite stopping members for deployment behind the syringe's distal tip on insertion of the syringe into said syringe port thereby precluding inadvertent syringe detachment from said syringe port, and said drug administration port having a widened distal tip for preventing a conventional needle being slidingly mounted thereon.
