In the examination room immediately after the procedure:
1. Wipe the insertion tube with a disposable cloth dampened in an enzymatic detergent solution.
Wipe the endoscope still attached to the light source, grasp the control head and using a disposable cloth dampened in freshly prepared enzymatic detergent solution, wipe the insertion tube from the control head to the distal tip.
Discard the cloth after use.
2. Aspirate enzymatic detergent solution through the suction/biopsy channels.
Place the distal tip in the enzymatic detergent solution.
Aspirate the enzymatic detergent through the entire suction/biopsy channel system until the expelled solution is visibly clean.
- Immediate flushing of the biopsy/suction and air/water channels prevents drying of organic and inorganic debris on lumen surfaces and assists in the removal of large numbers of microorganisms.
Alternate the suctioning of enzymatic detergent solution and air several times - finish by suctioning air.
- Alternate suctioning of fluid and air creates agitation and is more effective than suctioning fluid alone in dislodging debris from internal lumens.
3. Purge air/water channels.
Further processing depends on the type of endoscope.
At this point either:
Disconnect the water bottle connector from the endoscope taking care not to contaminate its end.
Occlude water connector port on the light guide plug and depress water feed button until all water expelled.
4. Detach removable components
Remove the endoscope from the light source.
Attach protective video cap (if using video endoscope)
Transport to the cleaning area in a container that does not cause contamination of th environment
Remove all valves/buttons/caps and soak in enzymatic detergent solution
It is preferable to have extra supplies of valves/buttons/caps to ensure that adequate cleaning is performed prior to disinfection/sterilisation. This allows processing of valves/buttons/caps to be completed at an alternate time.
