Abstract

A fluid collection and disposal system which includes a reusable collection unit designed to be cleaned by a servicing unit after use. The servicing unit performs an automatic servicing cycle to remove the collected fluid from the collection unit and prepare it for reuse.

Claims

1. A servicing system for cleaning a reusable fluid collection unit, said servicing system comprising:

a servicing unit for servicing the fluid collection unit,

an attachment mechanism for attaching the fluid collection unit to said servicing unit for servicing, and

a fluid circuit for circulating fluid through the fluid collection unit including a sanitary circuit formed by attachment of said servicing unit and said collection unit, said fluid circuit further including air flow lines for injecting pressurized air into said sanitary circuit and liquid flow lines for injecting liquid into said sanitary circuit.

2. A servicing system according to claim 1 wherein said fluid circuit for circulating fluid through the fluid collection unit includes a pump.

3. A servicing system according to claim 1 wherein said means for circulating fluid through the fluid collection unit also includes a drain for diverting fluid therein.

4. A servicing system according to claim 1 wherein said attachment mechanism for attaching the fluid collection unit to said servicing unit for servicing attaches the fluid collection unit such that a portion of the fluid collection unit remains outside of said servicing unit to allow visual indication of servicing of the fluid collection unit by said servicing system.

5. A servicing system according to claim 1 wherein said servicing unit for servicing the fluid collection unit includes means for forming at least a first and second fluid flow connection between said servicing unit and the fluid collection unit, and said servicing unit further includes means for injecting fluid into the fluid collection unit through said first fluid flow connection and means for receiving fluid from the fluid collection unit from said second fluid flow connection.

6. A servicing system according to claim 5 wherein said sanitary circuit includes means for continuously circulating fluid from said servicing unit to the fluid collection unit through said first fluid connection and returning to said servicing unit from the fluid collection unit through said second fluid connection in a continuous cycle through said sanitary circuit.

7. A servicing system according to claim 6 wherein said sanitary circuit further includes a divert valve for diverting fluid therein to a drain.

8. A servicing system according to claim 1 wherein said attachment mechanism for attaching the fluid collection unit to said servicing unit for servicing includes a means for lifting the fluid collection unit.

9. A servicing system according to claim 8 wherein said means for lifting the fluid collection unit to said servicing unit for servicing further includes a lift activation mechanism positioned on said servicing unit, said lift activation mechanism operating to move said means for lifting between a first position in which the fluid collection unit is attached to said servicing unit for servicing, and a second position in which the fluid collection unit is detached from said servicing unit for insertion and removal therefrom,

said lift activation mechanism operating to move said means for lifting said fluid collection unit from said first to said second position and from said second to said first position when held in continuous activation by a user.

10. A servicing system according to claim 9 further including a display located on said servicing unit, said display including said lift activation mechanism thereon.

11. A servicing system according to claim 10 wherein said display further includes a means for indicating the progress of said servicing unit in servicing the fluid collection unit.

12. a servicing system according to claim 1 wherein said means for circulating liquid through said fluid collection unit includes means for circulating a liquid detergent through the fluid collection unit.

13. A servicing system according to claim 1 wherein said means for circulating liquid through the fluid collection unit includes means for circulating a disinfectant through the fluid collection unit.

14. A servicing system for cleaning a reusable fluid collection unit, said servicing system comprising:

a servicing unit means for servicing said fluid collection unit,

an attachment mechanism for attaching said fluid collection unit to said servicing unit for servicing, and

a fluid circuit for passing fluid through said servicing unit and the collection unit to a drain, said fluid circuit including a sanitary circuit formed by the attachment of said servicing unit to the collection unit for circulating fluid between said servicing unit and said collection unit, air flow lines for pressurized air into said sanitary circuit and liquid flow lines for injecting liquid into said sanitary circuit.

15. A servicing system according to claim 14 wherein said sanitary circuit for circulating fluid through said servicing unit and said fluid collection unit includes a pump for circulating liquid through said sanitary circuit.

16. A servicing system according to claim 14 wherein said sanitary circuit for circulating fluid through said fluid collection unit also includes a divert valve for diverting fluid into a drain.

17. A servicing system according to claim 14 wherein said attachment mechanism operates to attach said fluid collection unit to said servicing unit such that a portion of said fluid collection unit remains outside of said servicing unit to allow visual verification of servicing of said fluid collection unit by said servicing system.

18. A servicing system according to claim 14 wherein said servicing unit includes at least a first and a second fluid flow connector for connecting said servicing unit and said fluid collection unit said first and second connectors being part of said sanitary circuit, whereby in operation said servicing unit injects fluid into said fluid collection unit through said first fluid flow connector and receives fluid from said fluid collection unit through said second fluid flow connector.

19. A servicing system according to claim 14 wherein said attachment mechanism for attaching said fluid collection unit to said servicing unit for servicing includes a lifting mechanism for lifting said fluid collection unit into attachment position with said servicing unit.

20. A servicing system according to claim 19 wherein said attachment mechanism for attaching said fluid collection unit to said servicing unit for servicing further includes at least one lift activation button positioned on said servicing unit, said at least one lift activation button operating to move said lifting mechanism between a first position in which said fluid collection unit is attached to said servicing unit for servicing, and a second position in which the fluid collection unit is detached from said servicing unit for insertion and removal therefrom,

said at least one lift activation button operating to move said lift mechanism from said first to said second position and from said second to said first position when held in continuous activation by a user.

21. A servicing system according to claim 20 further including a display located on said servicing unit, said display including said at least one lift activation button thereon.

22. A servicing system according to claim 21 wherein said display further includes cycle progress indicators for indicating the progress of said servicing unit in servicing said fluid collection unit.

23. A servicing system according to claim 14 wherein said liquid flow lines for injecting liquid into said sanitary circuit include a detergent metering pump mechanism for injecting a liquid detergent into said liquid flow lines.

24. A servicing system according to claim 14 wherein said liquid flow lines for injecting liquid into said sanitary circuit includes a disinfectant metering pump mechanism for injecting a liquid disinfectant into said liquid flow lines.
