By pushing a scope switch, endoscopes can change the light mode.
FUJIFILM endoscopes have 3 different light modes, white light, BLI and LCI.
White light has been the golden standard for observation but special light modes such
as BLI and LCI are expected to enhance observation and are gathering attention.
White light BLI(Blue Light Imaging) LCI(Linked Color Imaging)

4. How to feed air
When you block the air water button, air goes through the tip of the endoscope.

15. 4. Mechanism of air feed
Usually, air flows from the light source and out of the air water button.
When you cover the air water button, air goes through the tip of the endoscope.

17. 5. CO2 or room air?
Usually, room air is used for air inflation. However, C02 can be an alternative in
Advanced procedures, lengthy procedures and unsedated procedures.
CO2 is absorbed by the body 150 times faster than air
⇒CO2 enables doctors to perform optimum procedures with minimum patients’
discomfort. from bloating with air and cramping.

22. 6. Mechanism of water feed
Usually, air flows from the light source and out of the air water button.
When you cover the air water button, the pressure in the water tank increases and water is
pushed out of it. This water goes to the tip of the scope.

7. How to do suction
When you press the suction button, suction is done by the tip of the endoscope.

26. 7. Mechanism of suction
： Suction Route
： Air Route
： Water Route
： Water Jet Route
Suction Pump
Usually, air is sucked from the tip of the scope and comes out of the suction button.
When the suction button is pushed, the sucked air goes towards to the suction pump instead.

27. What is the forceps valve for??
It reduces the leakage or backflow of air when an
accessory is used, so it should normally be kept
closed. If a soft endoscopic accessory is used,
opening the lid makes it easier to insert and
remove such soft endoscopic accessories.

Is the forceps valve attached ?
Is it damaged?
Is the suction valve damaged? Is it
stuck? Maybe Solid materials or
thick fluids have adhered to the
suction valve?
Is the Suction unit on? Is the suction
tube connected to the scope?
Hey! No suction!

① Length of scope ＜ Length of accessories
Working Length

Lengthof the accessory and scope is one important factor for compatibility
The length of the accessory must be longer than the length of the scope.
The length of the red letters below
must be considered as well.

Check! The

(other brands are used as well)
Why water jet?
Injecting water jet into the gastrointestinal lumen is helpful for maintaining a clear
endoscopic view, washing away blood or mucus in the lumen or on the surface of the tip
of the endoscope. This contributes to reducing time and discomfort of examination.

Why zoom
By diagnosing detailed surface and vessel patterns, doctors
characterize the lesion for treatment decision and decide their
treatment strategy.
How There are 2 types of magnification; Electrical zoom and
optical zoom. Electrical zoom is the conventional type of zoom and it
is like pinching in a smart phone(image quality gets bad). Optical
zoom does not compromise image quality.
