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

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.
