Patent ID: 8597232

Claim:
A flow control device for use with a syringe and at least one vial for reconstituting and administering a liquid drug dosage, the syringe having a reciprocal plunger with a proximal plunger head, the flow control device having a horizontal longitudinal axis and comprising: (a) a stationary core member co-directional with the longitudinal axis and having an inlet port co-directional with the longitudinal axis for sealing fluid connection with the syringe and a pair of radial directed lumens perpendicular to the longitudinal axis and in flow communication with said inlet port, said pair of radial directed lumens including a downward radial directed injection lumen for injecting liquid contents into a vial in flow communication therewith and an upward radial directed aspiration lumen for aspirating liquid contents from a vial in flow communication therewith; and (b) an outer tubular flow control member co-directional with the longitudinal axis, rotatably mounted on and at least partially radially surrounding said core member, and having at least one peripheral located vial port for sealed attachment of a vial thereto and an administration flow channel in flow communication with an outlet port for administrating the liquid drug dosage, the at least one vial port being positioned in a plane oriented perpendicular to the longitudinal axis, the flow control device being operative such that said inlet port is in flow communication with a single port of said at least one vial port and said outlet port at each flow control position of at least two predetermined flow control positions of said flow control member relative to said core member for initially establishing a liquid drug reconstitution flow path between the syringe and each vial of the at least one vial for enabling initial reconstitution of the liquid drug dosage according to a liquid drug reconstitution program and subsequently establishing a liquid drug administration flow path between the syringe and the outlet port for administration of the liquid drug dosage according to a liquid drug administration regime, the flow control member being movable between the at least two predetermined flow control positions via rotation of the flow control member with respect to the core member about the longitudinal axis to align the single port of said at least one vial port and said outlet port at each flow control position with one of the radial directed lumens of the core member.
