ULTRASOUND GASTROVIDEOSCOPE GF-UCT180
Figure 9.1
Flush water and air into the air/water channel
Do not use the air/water channel cleaning adapter for patient
examinations. It will cause continuous insufflation and could
result in patient injury.
To prevent clogging of the air/water nozzle, always use the
air/water channel cleaning adapter to clean the air/water
channel after each use.
1. Prepare clean water in a 500 cm
3
(500 ml) container.
2. Turn the light source ON.
3. Depress the air/water valve completely to feed water into the balloon
channel and wash away any liquid that remained in the balloon channel.
4. Switch “OFF” the airflow regulator on the light source.
5. Remove the air/water valve from the endoscope and place it in a container
of detergent solution (see Figure 9.2).
Water may drip from the air/water valve or cylinder when the
air/water valve is detached. The water dripping from the
air/water valve or cylinder is clean (i.e., sterile water in the
water container). If water is dripping from the air/water valve
or cylinder, hold the control section higher than the water
container during water feeding.
6. Attach the air/water channel cleaning adapter to the air/water cylinder of the
endoscope (see Figure 9.2).
