PENTAX Reprocessing step-by-step

Brief Instructions for Manual Reprocessing
 from our friends at PENTAX.
(Please note: These instructions apply only for standard GI Endoscopes. For all other products, please refer to the instructions for use. Please see the instructions for use for your endoscope regarding which components may be brushed cleaned according to model)

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

Alternately flush detergent solution and air through the 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 your instructions.)

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 your instructions. 

Perform Leakage Test 1- 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 1, disinfect the 
endoscope externally, and contact ESS Service Department. )

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 and

Always disconnect Leak Tester from scope above the fluid surface. 

Brush clean all of the channels that may be cleaned with brushes using the appropriate brush under fluid surface, following your instructions. 

Start brush cleaning with the power supply connector.

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

Finally, brush clean the channels - starting at the control body and moving towards the distal ends. 

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

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. 

Submerge endoscope entirely in disinfectant solution.

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

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. 

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. 

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. 

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 Instructions 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 degrees C. Pressure for leakage test may not exceed 0.2 bar. 

(PENTAX Medical and Endoscopy Support Services, Inc. accepts no liablity for damages arising from improper reprocessing. Country-specific regulations must be observed. )
