Pentax EG-2990i Instructions For Use Manual page 18

CAUTION:
Flexible endoscopes and other sophisticated medical devices are
constructed of special materials, unique parts and intricate components
with strict dimensional tolerances. Specialized assembly techniques
and application of specific sealants and/or adhesives are required to
ensure the watertight integrity and maintain the functionality of these
devices. It is therefore imperative that endoscopes be routinely checked
to ensure that parts used in their construction are not loose, missing or
compromised that could otherwise negatively affect the functionality of
these devices. Compromised or loose components could result in device
failure, endoscope damage (via fluid invasion) and/or in incomplete
decontamination of used instruments.
PENTAX recommends that prior to use endoscopes should be carefully
inspected for their integrity and checked for any "looseness" in the mating
or joining of components including the following parts/areas:
• the instrument channel inlet (biopsy inlet port) (1)
• the suction nipple (2)
• the air/water port (3)
• the water jet connector (4)
• any valve cylinder (5)
• basically, any inlet or outlet port associated with an internal channel, an
indirect patient contact portion of the endoscope
• strain relief boot along insertion tube and umbilical cord (rotate
clockwise only to tighten)
One method to check for looseness is to lightly grip the exposed part,
and while grasping the component carefully attempt to move it in
various directions. Use of a lint free gauze while grasping metal parts is
recommended as a protection for one's fingers.
If any part/component remains loose (after attempting to tighten)
and/or if there is any indication or suspicion of an abnormality or
outward signs of damage, do NOT use the endoscope. Contact your
local PENTAX service facility.
