OSF TYPE V60 OPERATION MANUAL
3.6 Inspection of the Endoscopic System
Inspection of the Endoscopic Image
Turn the power switches of the Video System Center and Display Monitor ON,
and inspect the endoscopic image as described in their respective instruction
manuals.
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 Remote Switch
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.
Inspection of the Air Feeding Function
If a stream of air bubbles comes out of the Air/Water Nozzle
even though the Air/Water Valve is not being operated and
the Distal End of the Insertion Tube is 10 cm or more below
the surface of the water, the air feeding function is still
operating. If the endoscope is used while air is continuously
being fed, over-insufflation and patient injury may result.
1.
Turn ON the switch of the airflow regulator on the Video System Center,
following the instructions given in the Video System Center’s instruction
manual.
2.
Immerse the Distal End of the Insertion Tube in sterile water to a depth of
10 cm. Confirm that no air bubbles are emitted when the Air/Water Valve is
not operated.
3.
With the Distal End immersed to a depth of 10 cm, cover the Hole in the
Air/Water Valve with your finger and confirm that air bubbles are
continuously emitted from the Air/Water Nozzle.
