Abstract

A system for simultaneously filling multiple reservoirs of an IV delivery system comprises a support frame, port positioners on the support frame for positioning a plurality of fill ports of a multiple chamber reservoir, a plurality of injection pumps for injecting a predetermined amount of a fluid, coupling devices for coupling the injection pumps to a fill port of a reservoir, and an actuator for simultaneously coupling the couplers to the fill ports and filling said reservoirs with a predetermined amount of a fluid.

Claims

1. A system for simultaneously filling multiple reservoirs of an IV delivery system, comprising:

a support frame;

means on said support frame for positioning a plurality of fill ports of a multiple chamber reservoir to be filled;

a plurality of injection pumps mounted on said frame for injecting a predetermined amount of a fluid;

coupling means for coupling said injection pumps to fill ports of a reservoir positioned on said frame; and

common actuating means for performing the combined functions of sequentially coupling said coupling means to said fill ports and actuating said pumps for filling said reservoirs with a predetermined amount of a fluid.

2. A filling system according to claim 1 wherein said injection pumps comprise syringes connected through check valve means to a source of fluid.

3. A filling system according to claim 2 wherein said actuating means is operative for actuating said syringes a different amount for injection a different amount of liquid.

4. A filling system according to claim 3 wherein said coupling means comprises an injection needle.

5. A filling system according to claim 4 wherein:

said positioning means is operative to hold said fill ports at a fixed position; and

said actuating means moves said syringes for inserting a needle therein into said fill ports.

6. A filling system according to claim 1 wherein:

said injection pumps comprise a pair of identical syringes; and

said actuating means forces a plunger of each of said syringes a different amount for injection predetermined different amounts of fluid.

7. A filling system according to claim 1 wherein:

said injection means comprises a pair of different size syringes; and

said actuating means forces a plunger of each of said syringes the same amount for injection predetermined different amounts of fluid.

8. A filling system according, to claim 6 wherein:

said actuating means moves said syringes a first predetermined amount for establishing said coupling; and

said actuating means moves a plunger of each of said syringes a second predetermined amount for said injection.

9. A filling system according to claim 8 wherein:

said actuating means comprises a carriage for supporting said syringes; and

means for moving said carriage for establishing said coupling.

10. A filling apparatus for filling multiple chamber IV infusion systems, comprising in combination:

an elongated support frame;

means on one end of said support frame for positioning a plurality of fill ports of a multiple chamber reservoir to be filled;

a plurality of injection pumps mounted on said frame for injecting a predetermined amount of a fluid;

coupling means for coupling said injection pumps to fill ports of a reservoir positioned on said support frame; and

common actuating means for performing the combined functions of sequentially coupling said coupling means to said fill ports and actuating said injection pumps for filling said reservoirs with a predetermined amount of a fluid.

11. A filling system according to claim 10 wherein said injection pumps comprise syringes connected through a check valve to a reservoir.

12. A filling system according to claim 11 wherein said actuating means moves said syringes a first predetermined amount for establishing said coupling;

and

said actuating means moves a plunger of each of said syringes for said injecting.

13. A filling system according to claim 12 wherein:

said injection means comprises a pair of identical syringes; and

said actuating means forces a plunger of each of said syringes a different amount for injection of different predetermined amounts of fluid.

14. A filling system according to claim 12 wherein said injection means comprises a pair of different size syringes;

and

said actuating means forces a plunger of each of said syringes the same amount for injection of different predetermined amounts of fluid.

15. A filling system according to claim 12 wherein said actuating means comprises manually operated means moveable on said support frame for engaging and forcing a plunger of each of said syringes the same amount for injection of different predetermined amounts of fluid.

16. A filling system according to claim 12 wherein said actuating means comprises power operated means moveable on said support frame for engaging and forcing a plunger of each of said syringes the same amount for injection predetermined different amounts of fluid.

17. A filling apparatus for filling multiple chamber IV site flushing systems, comprising in combination:

an elongated support frame comprising a central base member and a pair of elongated rails mounted thereto and extending fore and aft thereof;

a support table fixed on a forward end of said frame for supporting a multiple reservoir infusion apparatus;

means on said support frame adjacent said support table for positioning a plurality of fill ports of a multiple chamber reservoir of an infusion apparatus;

cradle means for reciprocably mounting a plurality of syringes on said rails of said support frame;

a plurality of syringes mounted on said rails of said support frame;

combined tubing and valve means connected to said syringes for connecting said syringes to a source of fluid for enabling said syringes to act as injection pumps for injecting a predetermined amount of said fluid;

coupling means for coupling each of said syringes to a fill port of a reservoir; and

common actuating means for performing the combined functions of sequentially coupling said coupling means to said fill ports and actuating said syringes for filling said reservoirs with a predetermined amount of a fluid.

18. A combination according to claim 17 wherein said coupling means comprises an injection needle;

and

said actuating means moves said syringes an amount sufficient to insert a needle thereof into said injection ports, and thereafter moves a plunger of each of said syringes a sufficient amount for injection of said predetermined amounts of fluid.

19. A filling system according to claim 18 wherein said actuating means comprises manually operated means moveable on said support frame for engaging and moving a plunger of each of said syringes for injection of fluid.

20. A filling system according to claim 18 wherein said actuating means comprises power operated means moveable on said support frame for engaging and forcing a plunger of each of said syringes for injection of fluid.

21. A filling system according to claim 20 wherein said power operated means comprises an air motor for operation of each of said syringes for injection of fluid.
