3. Use of the device
The numbers in grey circles refer to the quick guide on page 2� Before each procedure, prepare
and inspect each new endoscope as instructed below� Inspect other equipment to be used with
the endoscope as instructed in their respective instruction manuals� Should any irregularity be
observed after inspection, follow the instructions as described in section 6 "Troubleshooting"�
If the endoscope malfunctions, do not use it� Contact your Ambu sales representative for
further assistance�
3.1. Inspection of the device
•
Check that the pouch seal is intact, and that the endoscope's expiration date has not
yet passed� In case the pouch seal has been damaged or the expiration date is passed,
the endoscope must be discarded� 1a
•
Carefully peel off the peel pouch packaging of the endoscope and remove the protective
elements from the control section and the distal end� 1b
•
Carefully run your hand back and forth over the entire length of the insertion tube,
including the bending section and distal tip, of the endoscope to make sure that there are
no impurities or damages on the product such as rough surfaces, sharp edges or protrusions
which may harm the patient� Make sure to use an aseptic technique when performing
the above� Otherwise, the sterility of the product will be compromised� 1c
• Inspect the distal end of the endoscope's insertion tube for scratches, cracks or other
irregularities�
•
Confirm that the top opening of the insufflation/rinsing valve is not blocked�
• Turn the Up/Down and Right/Left control wheels in each direction until their respective
stops and then return them to their neutral position� Confirm that the bending section
functions smoothly and correctly, that the maximum angulation is achieved and that
the bending section returns to the neutral position� 1d
•
Confirm that the angulation locks are functional by locking and releasing them as described
in section 2�1� Turn the control wheels fully in all directions, lock the angulation in a fully
angulated position and confirm that the bending section is stable� Release the angulation
locks and confirm that the bending section straightens out�
•
Using a syringe, flush sterile water into the working channel� Ensure that there are no leakages
and that the water is emitted from the distal tip� 1e
•
If necessary, confirm compatibility with applicable accessory devices�
•
A spare suction valve is available if needed to replace the preinstalled one in the endoscope�
The spare suction valve is included in the packaging�
•
A new endoscope should be readily available so the procedure can be continued in case
a malfunction occurs�
3.2. Preparations for use
Prepare and inspect displaying unit, CO₂ insufflator, sterile insufflation/rinsing water bottle,
auxiliary irrigation pump, sterile water bottle, vacuum source and suction container including
tubes as described in their respective instruction manuals�
• Power up the displaying unit� 2
•
Carefully align the arrows on the endoscope connector with the grey port of the displaying
unit to prevent damage to the connectors� 3
•
Connect the endoscope to the displaying unit by plugging the endoscope connector into
its corresponding grey port on the displaying unit�
• Check that the endoscope is firmly locked to the displaying unit�
•
When using the endoscope, it is recommended to use a mouthpiece to prevent the patient
from accidentally biting the insertion tube�
3.3. Attaching ancillary equipment
The endoscope is designed to work with most commonly available medical suction and
insufflation/rinsing fluid management systems� The endoscope does not produce negative
pressure itself and therefore an external vacuum source (e�g� wall suction or medical grade
suction pump) will be required to operate the system� As the endoscope has a standard
suction connector, standard suction tubes are compatible with the endoscope as long as
a firm and tight connection is established� It is the responsibility of the user to consult and
follow all third-party manufacturer instructions and guidance applicable to the endoscopic
fluid management system chosen for use with the endoscope� To perform patient examinations
