The aScope™ Duodeno does not itself produce negative pressure and therefore an external
vacuum source (e.g. wall suction or medical grade suction pump) will be 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
will have 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 the use with the aScope™ Duodeno.
Connection to the Fluid Canister
To perform patient examinations or procedures, all fluid containers (e.g. sterile water bottle)
must be properly and securely connected to the aBox™ Duodeno to prevent spillage, thereby
maintaining a safe work environment. Place the containers in the designated locations and connect
them according to the instructions in this chapter. Please note that a new suction canister/sterile
water bottle must be used for each procedure.
CO₂ Connection/Connecting the Insufflator
The aScope™ Duodeno is designed to work with a source of medical grade CO₂ for insufflation. The
maximum medical grade CO₂ supply pressure is 12psi (80kPa). Connect to the aScope™ Duodeno
using a tube with a luer-lock connector.
•
If ancillary equipment is ON turn OFF
•
Connect the luer-lock of the insufflation tubing from the insufflator to the insufflation
connector of the aScope™ Duodeno.
•
Turn the ancillary equipment back ON
Connection to the Suction System
Regardless of the vacuum source chosen, the aScope™ Duodeno will require the source to provide
a vacuum of min. -7psi (-50kPa) and max. -11psi (-76kPa) for the endoscope to operate normally.
Failure to provide the minimum vacuum requirements could result in a decreased capacity in
removing patient waste and/or irrigation fluid and loss of the cooling function.
•
If ancillary equipment is ON turn OFF
•
Fit the end of the suction tubing securely over the suction connector located on the endo
-
scope connector of the aScope™ Duodeno.
•
Connect the other end of the suction tubing from the suction connector of the aScope™
Duodeno to the external suction system (e.g. wall suction or medical suction pump).
•
Turn the ancillary equipment back ON
Electrical Connection to the aBox™ Duodeno
•
Make sure all connections above have been completed, the ancillary devices and the aBox™
Duodeno has been set and powered up.
•
The aBox™ Duodeno indicates when it is ready by displaying the information message on
the main monitor screen: “please connect endoscope”. For detailed information about
setting-up the aBox™ Duodeno please refer to the IFU of the specific device.
•
Lift the endoscope connector cover on the aBox™ Duodeno and plug the endoscope
connector into the connector socket of the aBox™ Duodeno.
•
The system will ask you first to confirm that a new bottle of sterile water was prepared for
the procedure.
•
Once confirmed the system will display the live procedure image. For detailed information
about using the aBox™ Duodeno please refer to the IFU of the specific device.
The light muss be turned ON by the user. For detailed information about using the aBox™ Duodeno
please refer to the IFU of the aBox™ Duodeno.
