3.6 Inspection of the endoscopic system
Inspection of the endoscopic image
Do not stare directly into the distal end of the endoscope
while the examination light is ON. Otherwise, eye injury may
result.
1. Turn the video system center, light source, monitor, magnification controller
(for CF-H260AZL/I only) and endoscope position detecting unit (for
CF-Q260DL/I, CF-H260DL/I only) ON and inspect the WLI and NBI
endoscopic image as described in their respective instruction manuals.
2. Confirm that light is outputting from the endoscope’s distal end.
3. While observing the palm of your hand, confirm that the WLI and NBI
endoscopic image is free from noise, blur, fog, or other irregularities.
4. Angulate the endoscope and confirm that the WLI and NBI endoscopic
images do 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.
Inspection of the remote switches
All remote switches should be checked to work normally
even if they are not expected to be used. The endoscopic
image may freeze, or other irregularities may occur during
examination and may cause patient injury, bleeding, and/or
perforation.
Depress every remote switch and confirm that the specified functions work
normally.
Inspection of the air-feeding function
1.
Set the airflow regulator on the light source to “High”, as described in the
light source’s instruction manual.
2. Immerse the distal end of the insertion section in sterile water to a depth of
10 cm and confirm that no air bubbles are emitted when the air/water valve
is not operated.
