Reprocessing step-by-step

Brief instructions for manual reprocessing

These instructions apply only for standard GI Endoscopes. For all other products, please refer to the instructions for use (IFU)

Please see the instructions for use (IFU) for your endoscope regarding which components may be brushed cleaned according to model.

1
/

• Wipe insertion tube with a clean, lint-free cloth saturated with detergent solution immediately after examination

 

 

 

 

2
/

• Alternately flush detergent solution and air through suction channel

• Set the lever on the water bottle to “drain” and insufflate air alternately into air and water channel

• Clean any other channels (if present) with detergent solution

3
/

• Disconnect the endoscope from the processor/light source and suction pump

• Attach the soaking cap on power supply connector; for specialized devices, please use appropriate soaking cap according to IFU

4
/

• Remove all of the valves, the distal end cap (if present) and any further detachable components and submerge them in the detergent solution

• Perform all further steps regarding reprocessing for these components according to the IFU

 

 

 

 

 

5
/

• Perform leakage test I − the dry test

• During the dry test move the angulation control knobs gently and rotate the ocular (if present) to see if the pressure drops

• If the pressure drops, discontinue leakage test I, disinfect the endoscope externally, place the scope in the provided protective bag, attach a note to the scope case regarding the failed test and send to PENTAX Medical’s service department

6
/

• Perform leakage test II − the wet test • Submerge endoscope entirely in fluid; move the angulation control knobs and rotate the ocular (if present)

• If bubbles rise discontinue leakage test II; proceed then as described in step 5

• Disconnect leak tester from scope always above the fluid surface

 

 

 

7
/

• Brush clean all of the channels that may be cleaned with brushes using the appropriate brush under fluid surface, following the order according to the IFU

8
/

• Start brush cleaning with the power supply connector

 

 

9
/

• Brush clean valve cylinder(s) and any other openings

 

 

10
/

• Finally brush clean the channels starting at the control body and moving towards the distal end

• If there are cleaning adapters, connect them for filling the channels with cleaning solution

• Remove adapter at the beginning of the exposure time

11
/

• Remove endoscope and any detached components from the cleaning solution

• Use the cleaning adapter to rinse all of the channels and rinse the external surfaces with clean water

 

 

 

12
/

• Submerge endoscope entirely in disinfectant solution

• Submerge any valves, the distal end cap (if present) and any further detachable components in the disinfectant solution

 

 

13
/

• Attach the cleaning adapter for filling the channels with disinfectant solution

• Remove adapter at the beginning of the exposure time

• Follow the manufacturer’s specifications in regard to disinfectant solution concentration and exposure time

 

 

14
/

• Remove endoscope and any detached components from the disinfectant solution

• Rinse all the channels and external surfaces with sterile-filtered or sterile water

• Dry the channels, using medical grade compressed air is recommended

 

 

15
/

• Remove protective caps and cleaning adapters (if present)

• Store the endoscope preferably by hanging it in a dust-free, well ventilated cabinet

• Store valves, distal end cap (if present) and other removable components separately from the endoscope 

 

16
/

• Attach valves, distal end cap (if present) and other removable components

• Inspect valve o-rings and change if they do not seal, moisten o-rings sparingly with silicone oil if necessary

• Connect endoscope to the processor/light source

• Perform functionality check

Note:

Review the IFU for further details.

Only use approved detergent and disinfectant solutions and follow the instructions regarding concentration, exposure time and temperature.

Steps 12 and 14 may also be performed with washer-disinfectors for flexible endoscopes. Washer-disinfectors may not be exposed to temperatures above 60° C. Pressure for leakage test may not exceed 0.2 bar.

PENTAX Medical accepts no liability for damages arising from improper reprocessing. Country-specific regulations must be observed.
