Ambu aScope 5 Broncho Bedienungsanleitung Seite 11

Endoscope buttons 5c 6a
The two endoscope buttons can activate up to four functions.
The endoscope buttons can be programmed via the Ambu display unit (see the Ambu display
unit's Instructions for Use) and current settings can be found in the user interface of the Ambu
display unit.
During use of active endotherapy instruments, the endoscope buttons cannot be activated on
the handle but functions are still available using the Ambu display unit.
Biopsy valve 6b
The biopsy valve is attached to the working channel port to enable 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 inserting the
endoscope into the patient. If the endoscopic image becomes unclear, clean the distal tip by
gently rubbing it against the mucosal wall, or remove the endoscope and clean the tip. When
inserting the endoscope orally, use of a mouthpiece is recommended to protect the patient
from injury and the endoscope from damage.
Instillation of fluids 7b
Fluids can be instilled through the working channel by attaching a syringe to the biopsy valve.
When using a Luer Lock syringe, use the included introducer. Insert the syringe tip or the
introducer completely into the biopsy valve (with or without the valve's cap attached) and
press the plunger to instill fluid. Make sure you do not apply suction during this process, as
doing this will direct the instilled fluids into the suction collection system. To ensure that all
fluid has left the channel, flush the channel with 2 ml of air.
Aspiration 7c
When a suction system is connected to the suction connector, suction can be applied by
pressing the suction button with your index finger. Note that suction capability will be
reduced if the introducer and/or an endoscopic accessory is positioned inside the working
channel. For optimal suction capability, removing the introducer or syringe entirely during
suctioning is recommended.
Insertion of endotherapy instruments or accessories 7d
Always make sure to select the correct size endotherapy instrument for the endoscope (see
section 2.2). The maximum compatible instrument size is indicated at the working channel port.
Inspect the endotherapy instrument before using it. If there is any irregularity in its operation
or external appearance, replace it. Insert the instrument into the biopsy valve and advance it
carefully through the working channel until it can be seen on the endoscopic image.
For insertion, hold the endotherapy instrument close to the opening of the biopsy valve and
insert it straight into the opening using gentle short strokes to prevent the endotherapy
instrument from bending or breaking. The enclosed introducer can be used to ease insertion
of very soft instruments, such as soft catheters and protected specimen brushes, if necessary.
Use of excessive force during insertion could damage the endotherapy instrument. When the
bending section of the endoscope is angled significantly and insertion of the endotherapy
instrument becomes difficult, straighten the bending section as much as possible.
