 Suction
• Avoid aspirating solid matter or thick fluids; instrument
channel, suction channel, or suction valve clogging can
occur. If the suction valve clogs and suction cannot be
stopped, disconnect the suction tube from the suction
connector on the endoscope connector. Turn the suction
pump OFF, detach the suction valve and remove solid matter
or thick fluids.
• If the suction valve clogs and the suction cannot be used
when solid matter, such as the clip or thick fluid, are
aspirated, withdraw the endoscope and disconnect the
suction tube from the suction connector on the endoscope
connector. Attach a syringe containing sterile water to the
suction connector. Straighten the insertion tube as much as
possible and forcefully flush the connector with the water
while the suction valve of the endoscope is slightly
depressed. Repeat the flush until the thick fluid or solid
matter are discharged from the distal end of the suction
channel. After discharging, confirm that there is no
irregularity in the suction function according to “Inspection of
the suction function” on page 82, before using the endoscope
again. If the thick fluid or solid matter cannot be discharged,
stop using the suction function and contact Olympus.
• When aspirating, maintain the suction pressure at the lowest
level necessary to perform the procedure. Excessive suction
pressure could cause aspiration of and/or injury to the
mucous membrane. In addition, patient fluids could leak or
spray from the biopsy valve, posing an infection control risk.
• When aspirating, attach the cap to the main body of the
biopsy valve. An uncapped biopsy valve can reduce the
efficacy of the endoscope’s suction system and may leak or
spray patient debris or fluids, posing an infection control risk.
During the procedure, make sure that the suction bottle does
not fill completely. Aspirating fluids into a full bottle may
cause the suction pump to malfunction.
Depress the suction valve to aspirate excess fluids or other debris obscuring the
endoscopic image (see Figure 4.5).
