1.
Before inserting or withdrawing the endoscope, set the insertion tube to an
appropriate level of flexibility by turning the flexibility adjustment ring as
required (see Figure 4.3).
Figure 4.3
2.
When changing the insertion tube’s flexibility during a procedure, turn the
flexibility adjustment ring slowly, and closely monitor the position of flexibility
index marking, the endoscopic image and the patient’s condition.
Whenever the endoscope is not in use, set the insertion tube
to its softest condition. Otherwise, endoscope damage may
result.
Air/water feeding and suction
• Before using a syringe to inject liquid through the biopsy
valve, detach the valve’s cap from the main body. Then insert
the syringe straight into the valve and inject the liquid. If the
cap is not detached and/or the syringe is not inserted
straight, the biopsy valve could be damaged, which could
reduce the efficacy of the endoscope’s suction system, and
may leak or spray patient debris or fluids, posing an
infection-control risk.
• 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.
