Flushing disinfectant solution into all channels
Completely remove all air bubbles from all channels.
Disinfection effects cannot be obtained if air bubbles remain
in the channels.
Air bubbles removal can be facilitated by injecting
disinfectant solution into the channels with strong force.
1. Immerse the endoscope and all equipment in the disinfectant solution.
2. Confirm that the suction port of the injection tube is immersed in disinfectant
solution.
3. Using the 30 cm
3
(30 ml) syringe, flush at least 90 cm
3
(90 ml) of
disinfectant solution through the air/water and suction channels respectively
via the injection tube. Confirm that no air bubbles exit the distal end of the
endoscope (see Figure 3.30 and 3.33).
4. Using the 5 cm
3
(5 ml) syringe, flush 10 cm
3
(10 ml) of disinfectant solution
through the elevator wire channel via the washing tube. Confirm that no air
bubbles exit the distal end of the endoscope (see Figure 3.31 and 3.32).
5. While immersed in disinfectant solution, raise the forceps elevator and flush
the vicinity of the forceps elevator with disinfectant solution using the 5 cm
3
(5 ml) syringe.
Soaking the endoscope and all equipment in disinfectant
solution
All disinfection steps should be performed with the
endoscope and all equipment completely immersed. If the
equipment is disconnected while not immersed, disinfectant
solution may not adequately contact all surfaces. As a result,
the effectiveness of disinfection may be reduced.
1. With the endoscope and all equipment completely immersed in the
disinfectant solution, disconnect all equipment from the endoscope. Leave
the endoscope and all equipment immersed in the disinfectant solution.
2. If air bubbles adhere to the surfaces of the endoscope and/or equipment,
remove them using a clean lint-free cloth.
3. Cover the basin with a tight fitting lid to minimize the diffusion of disinfectant
vapors.
