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
is inserted into the patient. If the endoscopic image becomes unclear, the distal tip can be
cleaned by gently rubbing the distal tip against the mucosal wall or remove the endoscope
and clean the tip. When inserting the endoscope orally, it is recommended to use a
mouthpiece to protect the patient and the endoscope from being damaged.
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 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 the index finger. If the introducer and/or an endoscopic
accessory is placed inside the working channel, note that the suction capability will be
reduced. For optimal suction capability it is recommended to remove the introducer or
syringe entirely during suction.
Insertion of endotherapy instruments or accessories 7d
Always make sure to select the correct size endotherapy instrument for the endoscope
(see section 2.2). 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 avoid the endotherapy
instrument to bend or break. 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 may damage the endotherapy instrument. When the bending
section of the endoscope angulates significantly and insertion of the endotherapy instrument
becomes difficult, straighten the bending section as much as possible.
