4. 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 aScope Gastro as instructed below. Inspect other
equipment to be used with the aScope Gastro 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 aScope Gastro malfunctions,
do not use it. Contact your Ambu sales representative for further assistance.
4.1. Inspection of the device
•
Check that the pouch seal is intact and discard the aScope Gastro if the sterile seal
has been damaged.
•
Confirm that the aScope Gastro is good to use by checking the expiry date. Discard
the device if it has expired.
•
Carefully peel off the peel pouch packaging of the aScope Gastro and remove the
protective elements from the control section and the distal end.
•
Carefully run your hand back and forth over the entire length of the insertion tube,
including the bending section and distal tip, of the aScope Gastro 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
1c
compromised.
•
Inspect the distal end of the aScope Gastro´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.
•
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.
•
If necessary, confirm compatibility with applicable accessory devices.
•
A spare suction valve is available if needed to replace the preinstalled one in the
aScope Gastro. The spare suction valve is attached to the mounting card next to the
aScope Gastro.
•
A new aScope Gastro should be readily available so the procedure can be continued
in case a malfunction occurs.
4.2. Preparations for use
Prepare and inspect aBox 2, 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 aBox 2.
•
Carefully align the arrows on the aScope Gastro connector with the grey port of the
aBox 2 to prevent damage to the connectors.
•
Connect the aScope Gastro to the aBox 2 by plugging the aScope Gastro connector
into its corresponding grey port on the aBox 2.
•
Check that the aScope Gastro is firmly locked to the aBox 2.
•
When using the aScope Gastro, it is recommended to use a mouthpiece to prevent
the patient from accidentally biting the insertion tube.
