How to Use
5.2.5 Operating Air/Water Valve
Operate the air/water valve to supply air or water from the air/water nozzle in the distal end
during a procedure.
Note Do not operate the air/water valve under the following conditions while the endoscope
is inserted in the body cavity. Doing so may cause the backflow of body fluid and
contaminate the sterile water in the water tank.
- The air supply pump of the light source is set to “OFF”.
- The connector of the water tank is not attached to the water supply connector of the
endoscope.
- The video connector of the endoscope is not connected to the scope connector
socket of the processor.
(2)
(1) When the hole in the air/water valve is covered with one’s finger, air is supplied to the air/water
nozzle in the distal end.
(2) When the air/water valve is pressed, water is supplied to the air/water nozzle in the distal end.
Note • If patient material adheres to the distal objective lens or if the image is obscured,
clean the surface of the lens by operating the air/water valve and supplying water.
• If any debris such as mucus is left adhered, or if air is supplied without supplying
water, the debris may become hard to remove due to drying or fixation.
• After operating the air/water valve, if the endoscopic image is unclear due to the light
reflected off the water droplets remaining on the objective lens or distal cap, it may
be improved by performing suction.
