Ambu aScope 5 Broncho 4.2 Mode D'emploi page 11

4. Instill 2 ml of sterile water and 2 ml of air into the working channel using a syringe
(if applying a Luer Lock syringe, use the enclosed introducer). Press the plunger to ensure
that there are no leaks, and that water is emitted from the distal tip. 5d
5. If applicable, prepare the suction equipment according to the manufacturer's Instructions
for use. Connect the suctioning tube to the suction connector and press the suction
button to check that suction is applied. 5e
6. If applicable, verify that endotherapy instruments of appropriate size can be passed
through the working channel without resistance. The enclosed introducer can be used for
connection of Luer Lock syringes or to ease insertion of very soft instruments such as soft
catheters and protected specimen brushes if necessary. 5f
7. If applicable, verify that the accessories or endotherapy instruments are compatible with
the endoscope before starting the procedure.
8. To guard against potentially infectious materials during the procedure, consider wearing
personal protective equipment.
4.2. Operating the aScope 5 Broncho
Holding the aScope 5 Broncho and manipulating the tip
The handle of the endoscope can be held with either hand.
Use the thumb to move the control lever up and down and the index finger to operate the
suction button. The control lever is used to flex and extend the distal tip of the endoscope in
the vertical plane 5a . Moving the control lever downward will make the tip bend anteriorly
(flexion). Moving it upward will make the distal tip bend posteriorly (extension). The insertion
cord should be held as straight as possible at all times in order to secure an optimal bending
angle at the distal tip. After bending, the control lever should be moved back to neutral
position. This will increase/ease maneuverability.
Rotation of the insertion cord 5b
The rotation control ring enables the user to rotate insertion cord in relation to the handle, and
vice-versa. This can be done either by holding the rotation control ring in place and then
rotating the handle, or by holding the handle in place and then rotating the rotation control
ring. In either case, make sure to check the rotation indicators on the rotation control ring and
on the red ring above. The rotation is at neutral position (i.e. turned 0°) when the indicators are
aligned, this will allow a maximal rotation of 120° to either side. There is a tactile click
indicating when the rotation control ring is returned to the neutral position. Always view the
live endoscopic image when operating the rotation control ring to avoid patient injury.
Endoscope buttons 5c 6a
The two endoscope buttons can activate up to four functions.
The endoscope buttons can be programmed via the Ambu displaying unit (see Instructions for
use of the Ambu Displaying Unit) and current settings can be found in the user interface of the
Ambu displaying unit.
During use of active endotherapy instruments the endoscope buttons cannot be activated on
the handle but functions are still available using the Ambu displaying unit.
Biopsy valve 6b
The biopsy valve is attached to the working channel port allowing for insertion of endotherapy
instruments or attachment of syringes.
The cap of the biopsy valve can be detached to ease insertion of an endotherapy instrument
or accessory into the instrument channel port.
If not using an endotherapy instrument or accessory, always attach the cap to the biopsy
valve to avoid leakage and spraying of fluids from the open biopsy valve or reduction of
suction capability.
Tube connection 6c
The tube connection can be used to mount ETT with an ISO connector during intubation.
Insertion of the endoscope 7a
Lubricate the insertion cord with a water-based medical grade lubricant when the endoscope
