Mechanical Cleaning
-
As soon as the endoscope is removed from the patient, wipe off excess mucus, etc from the insertion tube. The endoscope should not be placed on any other work surface.
-
Place distal end of insertion tube in a sink of detergent and water and aspirate through suction channel for at least 30 seconds.
-
Turn off air pump and remove air/water valve. Place valve in bowl of detergent solution. Insert air/water channel cleaning adaptor.
-
Perform a leak test.
-
Turn air pump back on and operate air/water channel cleaning adaptor to feed air and water alternately for approximately 10 seconds each.
-
Disconnect endoscope from light source and immerse whole instrument in sink full of cleaning solution (Check that AC-10s adaptor is not still attached to endoscope).
-
Wash outside of the instrument with gauze swabs, and clean the distal tip thoroughly with a toothbrush.
-
Remove the air/water cleaning adaptor, suction valve, biopsy valve (and distal hood and CO2 valve on colonoscopes), and place them in a small bowl of detergent solution.
-
Insert special OES cleaning brush through biopsy channel opening and brush through the tip of the endoscope. Clean brush and repeat at least three times.
-
Pass the cleaning brush through the suction valve hole into the instrument channel to the tip of the endoscope. Clean the bristles carefully before withdrawing the brush. Repeat until the channel is clean.
-
Pass the cleaning brush down the universal cord suction channel, again cleaning the brush before withdrawal.
-
After brushing all the channels, they must be flushed with detergent.
-
For side-viewing endoscopes, clean the forceps raiser mechanism carefully with a denture brush. Attach the forceps raiser channel cleaning tube and flush thoroughly with detergent solution.
White Permit Label
-
Using an endoscope washer-disinfector (EWD)
-
Connect the all-channel irrigator to the endoscope and immerse the entire instrument in an EWD. (For side viewing endoscopes, attach the forceps raiser channel cleaning tube and fill the channel with the disinfectant prior to immersion in the EWD.) Leave the endoscope immersed in the disinfectant for the recommended time.
-
At the end of the list, clean the suction and air/water valves in the ultrasonic cleaner for 10 minutes, then disinfect them as above. Dry and lubricate with Silicone Oil before replacing them. Send water container to CSSD for autoclaving at the end of the list.

A leak test must be performed
