ABSTRACT:
An apparatus for the rapid, accurate and sterile filling of unit dosage, injection syringes with medication from a bulk source container or for reconstituting vials of drugs. A clamping means is mounted to a support frame for releasably retaining the outer cylinder member of a disposable, relatively large-volume, pumping syringe against all movement relative to the support frame. A gripper means for removable attachment to the piston member of the pumping syringe is mounted to the frame for linear reciprocation along the axis of the pumping syringe. A crank means, which has an adjustable offset for selecting dosage volume, is drivingly connected to a motor drive means and an associated connecting rod links the crank means to the gripper means for reciprocally driving the piston member of the pumping syringe. A disposable, dual check valve, tee connector is connected to a mating connector on the pumping syringe. It has an inlet connected to the bulk source container and an outlet port formed into a female Luer connector for receipt of the injection syringe or other male Luer connector. The motor drive means is energized by a control circuit for driving the crank through a single rotation to complete one pump cycle and fill the unit dosage syringe in response to a depression of the foot pedal actuating switch.
