4.2.3 To Suck Mucus
To suck mucus, insert the distal end of the ultrasonic
endoscope in the mucous lake and press the suction valve
halfway.
[Note]
Do not suck in solid or viscous materials with the
ultrasonic endoscope. Such material may clog the
instrument channel or stick to the suction valve preventing
proper stopping of suction.
[Note]
During ultrasonic procedures in which a balloon is
not used, do not fully depress the suction valve and do
not attempt to aspirate patient material into/through
the balloon evacuation channel. Doing so can result in
partial or complete clog of the narrow balloon evacuation
channel, especially if the ultrasonic endoscope is not
cleaned immediately after each procedure and if not
reprocessed as per FUJIFILM recommendations.
4.2.4 If Mucus Adheres to the Distal Objective Lens or If the Image is Obscured
If mucus adheres to the distal objective lens or if the image
is obscured, clean the surface of the lens by pressing the
air/water valve halfway. When cleaning is complete,
remove water from the surface of lens by activating air
delivery and then suction.
[Note]
If any debris such as mucus is left adhered, or if air is
supplied without supplying water, the debris may become
hard to remove due to drying or fixation.
