Abstract: An apparatus for filling relatively smaller containers with measured amounts of liquid from a bulk container. A motor drive means (24) is mounted to a support frame for periodically operating a pumping syringe (30). A dual check valve (32) is connected to permit fluid flow from a bulk source (34) into the pumping syringe (30) and from the pumping syringe (30) to a relatively smaller receiving container (36). A clamping means (38) is mounted to the support frame for releasably retaining the outer cylinder member (52) of the pumping syringe (30) in a vertical orientation with its Lure connector uppermost. A gripper means (58) is slideably mounted to the support frame below the clamping means (38) for linear reciprocation parallel to the axis of the pumping syringe (30) and is releasably attached to the piston member of the pumping syringe (30).

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.
