Air/water feeding
EVIS EXERA TJF TYPE 160VR OPERATION MANUAL
•
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.
•
If the sterile water level in the water container is too low, then
air, not water, will be supplied. In this case, turn OFF the
airflow regulator on the light source and add sterile water till
the upper bound of the specified water level in the water
container.
•
If air/water feeding does not stop, turn OFF the airflow
regulator on the light source and attach a new air/water
valve.
