Reprocessing step-by-step

Brief instructions for reprocessing in washer-disinfectors

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 washer-disinfector as well as the endoscope to be reprocessed.


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






• 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


• 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


• 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







• Perform leakage tests according IFU

• 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


• 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 manufacturer’s specifications









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






• 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

• Remove adapter at the beginning of the exposure time


• 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




• Place endoscope in the washer-disinfector and connect all the channels according to washer-disinfectors manufacturer’s instructions

• After successful cleaning and disinfection, inspect for cleanliness





• Take a batch record printout from the washer-disinfector after successful cleaning and disinfection and release the endoscope for subsequent use

• File the batch record printout for records





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

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




• 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




Review the IFU for further details.

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

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.
