Syringe filling apparatus with disposable fluid conducting elements
First Claim
1. An apparatus for filling injection syringes with medical fluid from a source container and including a support frame for positioning said apparatus in a suitable work area and a motor drive means mounted to said frame, the apparatus comprising:
- a. a first pumping syringe;
b. a clamping means mounted to said frame releasably retaining the outer cylinder member of said pumping syringe against all movement relative to said frame;
c. gripper means for removable attachment to the piston member of said pumping syringe, said gripper means being mounted to said frame for linear reciprocation along the axis of said pumping syringe;
d. crank means drivingly connected to said motor drive means and an associated connecting rod linking said crank means to said gripper means for reciprocally driving said piston member; and
e. a dual check valve tee connector connected to a mating connector on said pumping syringe for permitting fluid to be drawn into and expelled from said pumping syringe, said tee connector having an input port for connection to said source container to permit the withdrawal of fluid from said container into said pumping syringe and also having an exhaust port formed into a female Luer connector for receipt of an injection syringe and permitting fluid flow from said pumping syringe to said injection syringe.

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.
