VISERA RHINO-LARYNGO VIDEOSCOPE ENF-V2
• Turn the video system center ON to operate the light source’s
automatic brightness function. When the video system center
is OFF, it cannot operate the light source’s automatic
brightness function, and the light intensity is set to the
maximum level. In this case, the distal end of the endoscope
can become extremely hot and could cause operator and/or
patient burns.
• Never insert or withdraw the endoscope with excessive force.
Otherwise, patient injury can result.
• If any of the following phenomena occur during an
examination, immediately stop the examination and withdraw
the endoscope from the patient as described in Section 10.2,
“Withdrawal of the endoscope with an abnormality” on
page 74.
If any abnormality is suspected with the functionality of
the endoscope.
If the endoscopic image on the video monitor disappears
or freezes unexpectedly.
If the endoscopic image on the video monitor appears
blurry of foggy unexpectedly.
If the angulation control mechanism is not functioning
properly.
Continued use of the endoscope under these conditions
could result in patient injury.
• If an abnormal endoscopic image/function occurs and returns
to its normal condition by itself, the endoscope has
malfunctioned. In this case, stop using the endoscope
because the abnormality can occur again and it may not
return to its normal condition. Therefore, stop the
examination immediately and slowly withdraw the endoscope
while viewing the endoscopic image. Otherwise, patient
injury can result.
• Wear personal protective equipment to guard against
dangerous chemicals and potentially infectious material
during operation. During operation, wear appropriate
personal protective equipment, such as eye wear, a face
mask, moisture-resistant clothing and chemical-resistant
gloves that fit properly and are long enough so that your skin
is not exposed.
