Chapter 3 Preparation and Inspection
2. Release the air/water valve. Observe the endoscopic image and confirm
that the emission of water stops and that the valve returns smoothly to its
original position.
3. While observing the endoscopic image, feed air after feeding water by
covering the hole in the air/water valve with your finger. Confirm that the
emitted air removes the remaining water on the objective lens and clears the
endoscopic image.
Inspection of the suction function
• If the suction valve does not operate smoothly, detach it and
reattach it, or replace it with a new one. If the endoscope is
used while the suction valve is not working properly, it may
be impossible to stop suction, which could cause patient
injury.
If the reattached or replaced suction valve fails to operate
smoothly, the endoscope may be malfunctioning; stop using
it and contact Olympus.
• If the biopsy valve leaks, replace it with a new one. A leaking
biopsy valve can reduce the efficacy of the endoscope’s
suction system, and may leak or spray patient debris or
fluids, posing an infection-control risk.
1. Turn the suction switchover lever on the biopsy valve so that “A” is facing
upward (see Figure 3.17).
2. Place the container of sterile water and the endoscope on the same height.
For the inspection, adjust the suction pressure to the same level as it will be
during the procedure.
