Abstract

A fluid collection and disposal system which includes a reusable collection unit designed to operate in conjunction with a disposable manifold for collecting fluids aspirated from a patient during a surgical procedure, and to be cleaned by a servicing unit after use. The servicing unit removes the collected fluid from the collection unit and prepares it for reuse. The disposable manifold is removed from the collection unit prior to its attachment to the servicing unit, and a new disposable manifold is replaced on the collection unit after servicing.

Claims

1. A fluid disposal system comprising:

collection means for collecting fluid,

manifold means removably attachable to said collection means for manifolding collected fluid into said collection means; and

service means for servicing said collection means separate from said manifold means.

2. The fluid disposal system according to claim 1 wherein said servicing means includes means for receiving said collection means.

3. The fluid disposal system according to claim 2 wherein said means for receiving includes a lifting means for lifting said collection means when positioned in said means for receiving said collection means.

4. The fluid disposal system according to claim 1 wherein said manifold means includes manifold extension connectors and said servicing means includes servicing extension connectors, and said collection means includes port means,

whereby said port means are alternatively connectable with said manifold extension connectors and said servicing extension connectors.

5. The fluid disposal system according to claim 4 wherein said collection means further includes a vessel lid, and said port means are formed in said vessel lid.

6. The fluid disposal system according to claim 4 wherein said port means includes a site glass port which is in fluid flow connection with said site glass.

7. The fluid disposal system according to claim 1 wherein said manifold means also comprises a valve means.

8. The fluid disposal system according to claim 7 wherein said valve means is an anti-reflux valve.

9. The fluid disposal system according to claim 1 wherein said collection means includes a vessel for receiving fluid collected by said collection means.

10. The fluid disposal system according to claim 9 wherein said vessel has a fluid volume of at least five liters.

11. The fluid disposal system according to claim 9 wherein said vessel has a fluid volume of at least 10 liters.

12. The fluid disposal system according to claim 9 wherein said vessel includes a site glass for visually indicating the volume of fluid within said vessel.

13. The fluid disposal system according to claim 12 wherein said site glass also operates as a drain for said vessel.

14. The fluid disposal system according to claim 12 wherein said site glass is integrally formed with said vessel.

15. The fluid disposal system according to claim 9 wherein said vessel is enclosed within said collection means.

16. The fluid disposal system according to claim 15 wherein said vessel is viewable through said collection means.

17. The fluid disposal system according to claim 15 wherein said collection means includes at least one transparent portion through which said vessel can be viewed.

18. The fluid disposal system according to claim 9 wherein said servicing means includes means for attaching said collection means thereto for servicing,

means for circulating fluid through said collection means which includes means for injecting fluid into said vessel and withdrawing fluid from a site glass.

19. The fluid disposal system according to claim 18 wherein said means for circulating fluid through said collection means includes means for circulating air through said collection means.

20. The fluid disposal system according to claim 18 wherein said means for circulating fluid through said collection means includes means for circulating a predetermined quantity of cleaning fluid through said collection means.

21. The fluid disposal system according to claim 18 wherein said means for circulating fluid through said collection means includes a pump.

22. The fluid disposal system according to claim 18 wherein said means for circulating fluid through said collection means also includes means for diverting fluid therefrom into a drain.

23. A fluid disposal system comprising:

a collection unit for collecting fluid,

a manifold removably attachable to said collection unit for manifolding collected fluid into said collection unit; and

a servicing unit for servicing said collection unit separate from said manifold.

24. The fluid disposal system according to claim 23 wherein said servicing unit includes a docking station for receiving said collection unit.

25. The fluid disposal system according to claim 24 wherein said docking station includes a lifting mechanism for lifting said collection unit when said collection unit is positioned inside said docking station.

26. The fluid disposal system according to claim 23 wherein said manifold includes a manifold extension connectors and said servicing unit includes servicing extension connectors, and said collection unit includes a plurality of ports,

whereby said plurality of ports are alternatively connectable with said manifold extension connectors and said servicing extension connectors.

27. The fluid disposal system according to claim 26 wherein said collection unit further includes a vessel lid, and said plurality of ports are formed in said vessel lid.

28. The fluid disposal system according to claim 26 wherein said plurality of ports includes a site glass port which is in fluid flow connection with a site glass.

29. The fluid disposal system according to claim 23 wherein said manifold also comprises a valve.

30. The fluid disposal system according to claim 29 wherein said valve is an anti-reflux valve.

31. The fluid disposal system according to claim 23 wherein said collection unit includes a vessel for receiving fluid collected by said collection unit.

32. The fluid disposal system according to claim 31 wherein said vessel has a fluid volume of at least five liters.

33. The fluid disposal system according to claim 31 wherein said vessel has a fluid volume of at least 10 liters.

34. The fluid disposal system according to claim 31 wherein said vessel includes a site glass for visually indicating the volume of fluid within said vessel.

35. The fluid disposal system according to claim 34 wherein said servicing unit includes an means for attaching said servicing unit to said collection unit for servicing,

means for circulating fluid through said collection unit which includes an injection means for injecting fluid into said vessel and withdrawing fluid from said site glass.

36. The fluid disposal system according to claim 35 wherein said means for circulating fluid through said collection unit includes means for circulating air through said collection unit.

37. The fluid disposal system according to claim 35 wherein said means for circulating fluid through said collection unit includes means for circulating a predetermined quantity of cleaning fluid through said collection unit.

38. The fluid disposal system according to claim 35 wherein said means for circulating fluid through said collection unit includes a pump.

39. The fluid disposal system according to claim 35 wherein said means for circulating fluid through said collection unit also includes means for diverting fluid therefrom into a drain.

40. The fluid disposal system according to claim 34 wherein said site glass also operates as a drain for said vessel.

41. The fluid disposal system according to claim 34 wherein said site glass is integrally formed with said vessel.
