Abstract

An integrated system for reprocessing contaminated medical instruments, e.g., scopes, surgical instruments, scope accessories, etc. The system includes plural, e.g., four, instrument processing units and a remotely located common controller for effecting the simultaneous control of each processing unit. Each processing unit includes various components, e.g., pumps, solenoids, valves, sensors etc., and a processing chamber. Each chamber is adapted for receiving a medical instrument carrier to which plural medical instrument in need of processing are connected. The controller includes a microprocessor, an associated memory storing a control program, a keyboard, a video display, and a printer. The control program establishes respective protocols of processing steps for effecting the reprocessing of the medical instruments in each of the reprocessing units by the microprocessor controlling the operation of the various components of the processing units via an electrical interface. The respective protocols are preestablished in accordance with the specific type of medical instrument to be reprocessed in the associated reprocessing unit. A database of information regarding previously processed instrument is stored within the system. Operation of the system can be monitored by viewing the video display. That display is selectable to graphically depict the various operational steps being accomplished in one or more of the processing units as those units are operated.

Claims

1. An integrated system for reprocessing contaminated medical instruments, said system comprising:

(a) a first reprocessing unit and a second reprocessing unit, said first and second reprocessing units being capable of operating at the same time, each of said first and second reprocessing units being adapted for receiving therein a medical instrument carrier, said medical instrument carrier being adapted to receive at least one of a predetermined type of contaminated medical instruments for the reprocessing thereof;

(b) electronic controller means including electronic processor means and associated memory means, said controller means being operably coupled to each of said first and second reprocessing units to enable simultaneous and/or individual control of the operation of said first and second reprocessing units;

(c) a control program for said controller means for disposition in said memory means, said control program establishing respective protocols of processing steps for effecting the reprocessing of the medical instruments in each of said first and second reprocessing units, said respective protocols being preestablished in accordance with the specific type of medical instrument to be reprocessed in the associated reprocessing unit; and

,

(d) said respective protocols comprising a first protocol of processing steps for effecting the reprocessing of contaminated medical instruments in said first reprocessing unit and a second protocol of processing steps for effecting the reprocessing of contaminated medical instruments in said second reprocessing unit, said first protocol of processing steps being different from said second protocol of processing steps.

2. The system of claim 1 additionally comprising visual display means for providing a visual display of various operating conditions of said system.

3. The system of claim 2 wherein said visual display means comprises a portion of said electronic controller means.

4. The system of claim 3 wherein said visual display means is arranged to produce a graphical display showing operating conditions of said system.

5. The system of claim 1 additionally comprising input means for enabling a user of said system to provide information into said system to effect the operation thereof.

6. The system of claim 1 additionally comprising a database containing reprocessing related information, said database being stored within said system for enabling the retrieval of selected information therefrom.

7. The system of claim 6 wherein said reprocessing related information comprises information relating to the instruments previously reprocessed by said system.

8. The system of claim 1 wherein said electronic controller means comprises a housing for disposition at a location remote from said reprocessing units.

9. The system of claim 1 wherein said electronic controller means enables the monitoring of the operation of each of said reprocessing units, as each of said reprocessing units is operated under the control of said electronic controller means.

10. The system of claim 9 wherein said electronic controller means additionally comprises visual display means for providing a visual display of operating conditions of said system.

11. The system of claim 10 wherein said visual display means is arranged to selectively produce a graphical display of the operating conditions of each of said reprocessing units of said system.

12. The system of claim 11 wherein said visual display means is arranged to selectively produce a graphical display of the operating conditions of all or selected ones of said reprocessing units of said system as said processing units are operated by said electronic controller means.

13. The system of claim 1 wherein said control program for establishing respective protocols of processing steps for effecting the reprocessing of the medical instruments in each of said reprocessing units is alterable within said memory.

14. The system of claim 1 wherein each of said reprocessing units comprises plural components selected from the group consisting of valves, sensors, pumps, and solenoids.

15. The system of claim 14 wherein at least some of said plural components of said reprocessing units is arranged to be in electrical communication with said electronic processor means.

16. The system of claim 15 additionally comprising electrical interface means coupled between said electronic processor means and at least some of said plural components of said reprocessing units.

17. The system of claim 1 wherein said first reprocessing unit is arranged for reprocessing flexible scopes and said second reprocessing unit is arranged for reprocessing surgical instruments.

18. The system of claim 17 additionally comprising a third reprocessing unit arranged for reprocessing flexible scope accessories.

19. The system of claim 1 wherein said electronic controller means additionally comprises a monitor and a graphical user interface, and wherein said graphical user interface displays a screen display on said monitor comprising a plurality of bays, each of said bays comprising a graphical illustration of the operation of a respective one of said reprocessing units of said system.

20. The system of claim 1 wherein said electronic controller means additionally comprises a printer.

21. The system of claim 1 wherein said medical instrument carrier is rectangular.

22. The system of claim 1 wherein said instrument carrier is circular.

23. The system of claim 1 wherein said instrument carrier additionally comprises an attachment means for attachment to a medical instrument having an internal surface and means for attachment to one of said plurality of reprocessing units.

24. The system of claim 1 wherein said protocol of reprocessing steps comprises at least one wash cycle and at least one rinse cycle.

25. The system of claim 24 wherein said protocol of reprocessing steps additionally comprises at least one chemical immersion cycle.

26. The system of claim 13 wherein said protocol of reprocessing steps additionally comprises at least one cycle for the application of a lubricant.
