Recommended action
Gently rub the distal tip against the
mucosa. If the lens cannot be cleaned
this way remove the endoscope and
wipe the lens with sterile gauze.
Clean the working channel using a
cleaning brush or flush the working
channel with sterile saline using a
syringe. Do not operate the suction
button when instilling fluids.
Ensure the suction tube is properly
connected to the endoscope and to the
suction system. Ensure suction system
is turned on.
Remove endotherapy instrument or
introducer/syringe from the working
channel port/biopsy valve. Check that
the instrument used is compatible with
the working channel's ID.
Ensure that the cap is attached
to the biopsy valve to avoid
reduction of suction capability.
Ensure compatibility of endotherapy
instrument to working channel size.
When the cap of the biopsy valve is
detached, it may be easier to insert an
endotherapy instrument into the
instrument channel port.
Set the endoscope button function as
preferred using the Instructions for use
for the displaying unit.
Remount suction button and test
the suction function according to
preparation step 5e . If that does not
work, then use new endoscope.
