4.
Angulate the endoscope and confirm that the endoscopic image does not
momentarily disappear or display any other irregularities.
If the object cannot be seen clearly, wipe the objective lens
using a clean, lint-free cloth moistened with 70% ethyl or
isopropyl alcohol.
All remote control switches should be checked to work
normally even when they are not expected for use. The
endoscopic image may freeze or other irregularities may
occur during examination and may cause patient injury,
bleeding, and/or perforation.
Depress every remote control switch and confirm that the specified functions
work normally.
• If the suction valve does not work smoothly, detach it and
attach it again or replace it with a new suction valve. If it still
does not work smoothly, the endoscope may be
malfunctioning; stop using it and contact Olympus. If the
endoscope is used while the suction valve is not working
smoothly, the valve may become stuck, which may make it
impossible to stop the suction operation.
• Do not aspirate with a pressure of more than 670 hPa
(0.68 kgf/cm
difficult to stop suction.
1.
The suction valve is connected to the endoscope.
2.
Immerse the distal end of the insertion section in sterile water and depress
the suction valve. Confirm that water is continuously aspirated into the
suction bottle of the suction pump.
3.
Release the suction valve. Confirm that suction stops and the valve returns
to its original position.
4.
Remove the distal end of the insertion section from the water. Depress the
suction valve and aspirate air for a few seconds to remove water from the
instrument channel.
