Inspection of the Suction Function
Set the aspiration pressure of the suction pump within the
range of –34 kPa to 0 kPa. Excessive aspiration pressure
may make it difficult to stop suction.
1. Turn the Suction Pump on.
2. Immerse the Distal End of the Insertion Tube in sterile water and depress
the Suction Lever. Confirm that water is continuously aspirated into the
suction bottle of the Suction Pump.
3. Release the lever. Confirm that suction stops and the lever returns to its
original position.
4. Remove the Distal End of the Insertion Tube from the water. Depress the
lever and aspirate air for a few seconds to remove water from the channel.
Inspection of the Water Feed
1.
Insert a syringe filled with sterile water into the Biopsy Valve and depress
the plunger.
2. Confirm that water is emitted from the Distal End of the endoscope.
• The syringe must be inserted fully and held perpendicular to
the Biopsy Valve for proper operation. Angled or incomplete
insertion may result in fluid leakage from the Biopsy Valve.
• Do not depress the Suction Lever during feeding. If the
Suction Lever is depressed during water feeding, water will
be aspirated into the suction tube and not emitted from the
endoscope’s Distal End.
• If water is not emitted from the endoscope’s Distal End, flush
air through the channel using the syringe.
