EVIS LUCERA GIF/CF/PCF TYPE 260 Series OPERATION MANUAL
• If the biopsy valve is left uncapped during the procedure,
debris or fluids could leak or spray from it, posing an infection
control risk. When the valve is uncapped, place a piece of
sterile gauze over it to prevent leakage.
• Nothing other than sterile water should be used for air/water
feeding. No additives should be put into the sterile water.
Non-sterile water may cause patient cross-contamination
and/or infection.
If the endoscope is cold, condensation may form on the
surface of the objective lens and the endoscopic image may
appear cloudy. In this case, increase the temperature of the
sterile water in the water container to 40 – 50C (104 –
122F) and then use the endoscope.
Air/water feeding
1. Cover the air/water valve’s hole to feed air from the air/water nozzle at the
distal end (see Figure 4.5).
2. Depress the air/water valve to feed water onto the objective lens (see Figure
4.5).
