Abstract

In a blood therapy apparatus having a load cell sensor and a coupler for securing a load, a bag thereon is characterized by a free hanging link hanging from the coupler, and a bag hanger comprising an elongated rod having a plurality of bag engaging hooks and upwardly extending hook secured at the weight center of the rod and freely hanging from the links.

Claims

1. An extracorporeal blood therapy apparatus comprising:

a control unit including a plurality of peristaltic pumps mounted in a control unit housing assembly;

a panel assembly comprising a plurality of panels removably mounted on said housing assembly and having blood tubing and fluid tubing secured on said panels and cooperating with said peristaltic pumps for directing blood and fluid therein;

one or more fluid holding bags in fluid communication with said fluid tubing;

one or more load sensors mounted on said control unit each having a coupler connected thereto and configured for hanging a fluid holding bag;

a bag hanger assembly characterized by one or more links freely and movably hanging from said coupler; and

a bag hanger comprising an elongated rod, an upwardly extending hook secured at the center of said elongated rod, and a plurality of downwardly extending hooks of substantially identical weight extending in the same direction from said rod and secured to said rod along the length thereof,

whereby said bag hanger removably hangs from said one or more links via said upwardly extending hook with said elongated rod extending substantially horizontally therefrom, said downwardly extending hooks configured for hanging a fluid holding bag thereon, and whereby said fluid holding bag and said bag hanger are independently movable relative to said coupler via said link.

2. The apparatus of claim 1 wherein said coupler comprises a hook.

3. The apparatus of claim 1 wherein said link comprises a ring.

4. The apparatus of claim 2 wherein said link comprises a ring.

5. The apparatus of claim 4 wherein said ring is annular.

6. The apparatus of claim 4 wherein said ring is oval.

7. The apparatus of claim 4 wherein said ring is ellipsoidal.

8. The apparatus of claim 1 wherein said bag hanger comprises a center downwardly extending hook and downwardly extending end hooks at opposite ends of said elongated rod.

9. The apparatus of claim 1 wherein said bag hanger comprises a vertical rod secured on said elongated rod having the upwardly extending hook secured on said link at the upper end thereof and a downwardly extending hook at the lower end thereof.

10. The apparatus of claim 8 wherein said downwardly extending end hooks comprise hook shaped opposite ends of said elongated rod.

11. The apparatus of claim 9 wherein said downwardly extending end hooks comprise hook shaped opposite ends of said elongated rod.

12. The apparatus of claim 8 wherein the length and arch of each of said downwardly extending hooks is substantially identical.

13. The apparatus of claim 1 wherein said link is configured for disengagement from said upwardly extending connector.

14. An apparatus for performing blood therapy comprising:

a control unit housing having a controller, a blood pump and a plurality of fluid pumps secured therein, a panel assembly comprising a plurality of removable panels installed on said housing, said panels having blood tubing and fluid supply tubing secured thereon configured for cooperating with said blood pump and fluid pumps for directing blood and fluid, respectively, therethrough;

one or more fluid holding bags cooperating with said fluid supply tubing for providing fluid thereto or receiving fluid therefrom; and

a bag weigh system comprising one or more load cell sensor assemblies each comprising a sensor and a coupler cooperating therewith for securing a load thereon, each said sensor operatively connected to said controller for communicating sensed load thereto, said bag weigh system characterized by;

one or more links freely hanging from said coupler, and

a bag hanger comprising an elongated rod having an upwardly extending hook secured at the weight center of said rod, said rod having a plurality of downwardly extending hooks secured along the length thereof and extending in the same direction from said rod, said bag hanger removably hanging from said one or more links via said upwardly extending hook,

and wherein a fluid holding bag is removably secured on and hangs from said downwardly extending hooks.

15. The apparatus of claim 14 whereby said downwardly extending hooks are spaced apart whereby the weight thereof is evenly distributed along said rod whereby the hanging rod is suspended substantially horizontally.

16. The apparatus of claim 14 wherein said coupler comprises a hook.

17. The apparatus of claim 14 wherein said link comprises a ring.

18. The apparatus of claim 16 wherein said link comprises a ring.

19. The apparatus of claim 18 wherein said ring is annular.

20. The apparatus of claim 18 wherein said ring is oval.

21. The apparatus of claim 18 wherein said ring is ellipsoidal.

22. The apparatus of claim 14 wherein said bag hanger comprises a center downwardly extending hook and downwardly extending end hooks at opposite ends of said elongated rod.

23. The apparatus of claim 22 wherein said bag hanger comprises a vertical rod secured on said elongated rod having the upwardly extending hook secured on said link at the upper end thereof and a downwardly extending hook at the lower end thereof.

24. The apparatus of claim 22 wherein said downwardly extending end hooks comprise hook shaped opposite ends of said elongated rod.

25. The apparatus of claim 23 wherein said downwardly extending end hooks comprise hook shaped opposite ends of said elongated rod.

26. The apparatus of claim 22 wherein the length and arch of each of said downwardly extending hooks is substantially identical.

27. The apparatus of claim 14 wherein said upwardly extending hook comprises a loop configured to prevent disengagement from said link.

28. The apparatus of claim 14 wherein said link is configured for selective disengagement from said upwardly extending hook.
