Attaching the air/water valve
Attach the air/water valve to the air/water cylinder of the endoscope (see Figure
3.14). Confirm that the valve fits properly without any bulging of the skirt.
Figure 3.14
The air/water valve may stick at first, but it should operate
smoothly after it is depressed a few times.
Attaching the biopsy valve
If a biopsy valve is not properly connected to the instrument
channel port, it can reduce the efficacy of the endoscope’s
suction system and may cause patient debris to leak or spray
from the endoscope.
Attach the biopsy valve to the instrument channel port of the endoscope (see
Figure 3.15). Confirm that the biopsy valve fits properly.
