EVIS LUCERA GIF/CF/PCF TYPE 260 Series OPERATION MANUAL
Performing both air feeding and suction at the same time
sometimes makes it easier to remove water droplets from the
objective lens surface.
Auxiliary water feeding (for endoscopes with auxiliary
water feeding only)
Nothing other than sterile water should be used for auxiliary
water feeding. No additives should be put into the sterile
water. Non-sterile water may cause patient
cross-contamination and/or infection.
• Never disconnect the auxiliary water tube from the auxiliary
water inlet during an examination; leave it attached until the
endoscope is precleaned. If the auxiliary water tube is
detached before precleaning, water remaining in the auxiliary
water channel may be spilled on the equipment. This could
cause damage and/or malfunction of the equipment.
• When the auxiliary water tube is not connected to the
auxiliary water inlet, be sure to have the auxiliary water inlet
cap attached to the auxiliary water inlet. Otherwise, patient
debris or fluids that back flowed may drip out of the auxiliary
water inlet.
1. Attach a syringe containing sterile water or the water tube from a water
pump to the luer port of the auxiliary water tube. Feed water.
2. When disconnecting the syringe or the water tube from the water pump
during the examination, disconnect it directly from the luer port but leave the
auxiliary water tube itself attached.
Observation of the endoscopic image
Do not rely on the NBI observation mode alone for primary
detection of lesions or to make a decision regarding any
potential diagnostic or therapeutic intervention.
Refer to the light source’s instruction manual for instructions on how to adjust the
brightness.
