• Confirm that the angulation locks are functional by locking and releasing the angulation
locks according to section 2.3. Turn the angulation wheels fully in all directions, lock
the angulation in a fully angulated position and confirm that the bending section
can be stabilized. Release the angulation locks and confirm that the bending section
straightens out.
• Confirm that the top hole of the insufflation/rinsing valve is not blocked. 1e
• Using a syringe, insert sterile water into the working channel. Press the plunger, ensure
that there are no leaks and that the water is emitted from the distal end. 1e
If applicable, confirm compatibility with applicable accessory devices as appropriate. 2

4.2. Preparation of the Endoscope
Prepare and inspect aBox™ Duodeno, medical grade monitor, suction pump, and insufflator as
described in their respective manuals.
• Prepare a bottle of sterile water and place it in the designed bottle holder located on the
front (left side) of the aBox™ Duodeno. For lens washing water it is recommended that
the sterile water bottle chosen should contain a minimum of 1000 ml in volume. Please
note that a new bottle of sterile water should be used for each procedure. 3
• Power up the aBox™ Duodeno. Once the aBox™ Duodeno has been set and powered up,
the system indicates when it is ready by displaying the settings and information menu
and the following information message: "please connect endoscope". 4
For detailed information about powering up the aBox™ Duodeno please refer to the IFU of the
aBox™ Duodeno.
• Slide the endoscope strain relief into the aBox™ Duodeno connector snap. 5a
• Open the housing of the peristaltic pump located on the front panel of the aBox™
Duodeno by gently pushing up the lid with your thumb(s) until the top of the peristaltic
pump is exposed.
• Carefully place the rinsing tubing of the aScope™ Duodeno around the roller of the
peristaltic pump making sure the tubing is not twisted. The rinsing tubing should cover
the roller of the pump and go underneath the roller pump.
• Close the peristaltic pump by pressing the lid of the housing down until the housing of
the peristaltic pump is closed. Make sure that the rinsing tubing is nestled within the
notches on each side of the roller before closing completely.
• Remove all seal caps/covers from the bottle of sterile water. Insert the process water
tubing into the bottle of sterile water. Ensure that the end of the tubing reaches to the
bottom of the water bottle so that the maximum volume of water can be suctioned from
the water bottle prior to replacing (as necessary) to reduce waste.
4.3. Attaching Ancillary Equipment to the Endoscope
The aScope™ Duodeno is designed to work with most readily available and most often utilized
medical suction and fluid management systems.
Irrespective of the chosen fluid management system, overflow protection must be a feature of
the suction canister assembly utilized in order to prevent fluids from entering the system. This
feature is commonly referred to as "self-sealing" feature or "shut-off-filter", or similar mechanism.
Please note that a new suction canister and connection should be used for each procedure.
The aScope™ Duodeno does not itself produce negative pressure and therefore an external
vacuum source (e.g. wall suction or medical grade suction pump) is required to operate the
system. Standard suction tubings with a nominal diameter should be sufficient, as long as they
simply and securely fit over the standard size suction connector of the aScope™ Duodeno.
Nomenclature used in this section follows the established convention that each canister
utilized has multiple connection ports labelled either "To Vacuum" or "To Patient". However, it is
the responsibility of the user to follow all manufacturer instructions and guidance applicable to
the endoscopic fluid management system chosen for use with the aScope™ Duodeno.
