BF-190 Series OPERATION MANUAL
WARNING
• When the endoscopic image does not appear on the monitor, the image sensor
may have been damaged. Turn the video system center OFF immediately.
Continued power supply in such a case will cause the distal end to become hot and
could cause operator and/or patient burns.
• Do not rely on the NBI observation mode alone for primary detection of lesions or to
make a decision regarding any potential diagnostic or therapeutic intervention.
• When performing transnasal insertion with the endoscope, follow the warnings
below.

The shape and size of the nasal cavity and its suitability for transnasal insertion
may vary from patient to patient. No endoscope, including this one, can always
be inserted transnasally into all patients. Before proceeding, always be sure to
confirm that transnasal insertion is possible with the patient by considering both
the size of the patient’s nasal cavity as well as the size of the endoscope’s
insertion section. Patient injury can result or the endoscope could become
lodged and difficult to withdraw.

Transnasal insertion is accompanied by the risk of inflammation of the nasal
cavity. If this happens, the nasal passage will be constricted, making it more
difficult to withdraw the endoscope. In this case, do not use force to withdraw
the endoscope because patient injury, bleeding, and/or perforation may result.

Transnasal insertion is accompanied by the risk of bleeding in the nasal cavity.
Be sure to be prepared to deal with any bleeding. When withdrawing the
endoscope, observe the inside of the nasal cavity to ensure that there is no
bleeding. Even when the endoscope has been withdrawn without bleeding, do
not allow the patient to blow his or her nose strongly because this could cause it
to start bleeding.

Before transnasal insertion, apply the appropriate pretreatment and lubrication
to the patient to enlarge the nasal cavity. Otherwise, patient injury can result or
the endoscope could become lodged and difficult to withdraw. When applying a
pretreatment agent through a tube, insert the tube into the same path as the
path planned for the endoscope’s insertion. Otherwise, the treatment will have
no effect. The effects of the pretreatment agent and lubricant will decrease the
longer the procedure lasts. Apply the pretreatment agent or lubricant as
required during the procedure – for example, when withdrawal seems to be
difficult.

Transnasal insertion of the endoscope should be performed carefully. If
resistance to insertion is felt, or the patient reports pain, stop the insertion
immediately. Patient injury can result or the endoscope could become lodged
and difficult to withdraw.
