Important Information — Please Read Before Use
• Never perform high-suction continuously. Patient injury can
result.
• Never tie the elastic opening of both sides of the balloon with
a thread. This may cause the balloon to rupture or detach
from the distal end of the endoscope when inflating it, and
could result in patient injury.
• Never inflate the balloon to a diameter of more than 20 mm
when using the endoscope in the trachea. This could result in
suffocation of the patient.
• Never withdraw the endoscope while the balloon is still
inflated. Otherwise, the balloon may burst or detach from the
distal end of the endoscope. If the balloon cannot be
deflated, insert the channel cleaning brush (BW-7B) into the
irrigation port. Using slow, short strokes, carefully feed the
brush to remove debris.
• When withdrawing the endoscope, make sure that the
balloon is completely deflated, using the ultrasonic image
and endoscopic field of view. Withdrawing the endoscope
while the balloon is inflated could result in patient injury.
• 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 such as
bleeding 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Even when the endoscope has been withdrawn without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 be difficult to withdraw.
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
withdrawal seems to be difficult.
