1) Inspection of the Insertion Portion
a) Check the entire surface of the insertion tube for abnormal conditions such as
sharp edges, dents, crush marks, wrinkles, bumps, buckles, excessive bending,
protrusions, bite marks, peeling of outer sheath, cuts/holes or other irregularities.
Any crush or indentation of the flexible shaft of the endoscopes can cause
damage to the internal mechanisms of the endoscopes.
b) Similarly, check the condition of the umbilical cord for outward signs of damage
such as buckling, crush marks, etc.
WARNING:
To avoid serious damage to the patient or possibility of malfunction during
a procedure, do not use any endoscope if you nd any abnormalities or
outward signs of damage.
c) These areas [A], [B] should be checked for ANY abnormalities or irregularities.
If anything unusual is found including but not limited to rough textured surfaces,
cracks, brittleness, sharp-edges, holes, peeling, tackiness, etc., the endoscope
should NOT BE USED. During this inspection process check the surface/
condition of the adhesive by applying slight pressure with one's gloved ngers
and by slightly wiping this area with dry gauze.
Make sure the adhesive band is not peeling, nor does it have roughened texture
or any sharp-edges.

d) Make sure that the entire endoscope is clean and has been subjected to either a
high-level disinfection or sterilization process before each patient use.
WARNING:
From the standpoint of infection control, all instruments must be
reprocessed prior to first time use, after any repairs/service and before
every patient use.
CAUTION:
In order to obtain crisp endoscopic images, when utilizing chemo-thermal
processes for reprocessing PENTAX endoscopes, the instruments should
be allowed to return to room temperature prior to use and/or further
handling.
