9) Prior to each procedure, check the endoscope image quality displayed on the monitor. Confirm that the image
quality, color, automatic brightness (iris) functions are acceptable as per the instructions provided with the
PENTAX video processor.
2-2. INSPECTION OF ENDOSCOPE
Before proceeding with inspection of individual functions, PENTAX endoscopes should be tested for the integrity
of their water-tight design (example: tear in the instrument channel). This test is described in another section of
this manual entitled: “Leakage Testing.”
1) Inspection of the Insertion Tube
a) Check the entire surface of the insertion tube for abnormal conditions such as dents, crush marks, wrin-
kles, 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 cable for outward signs of damage such as buckling, crush
marks, etc.
c) 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.
NOTE:
As indicated elsewhere in PENTAX product labeling, endoscopes particularly the quality of the endo-
scopic image should be checked prior to patient use.
CAUTION:
If the endoscope is intended to be clinically used after testing of individual scope functions (suction, air/
water delivery, water jet, etc.) without further reprocessing, the following precaution should be exercised.
Use “fresh” distilled or sterile water during individual scope function tests to avoid recontamination of the
previously reprocessed instrument by waterborne microorganisms. Tap water, especially that which may
be left idle and uncovered for a prolonged period of time, should not be used during any inspection/test-
ing of the endoscope.
CAUTION:
Various types of endoscope leakage testers exist including manual, electro-mechanical and “automated”
versions, some of which are stand alone units and others which may be integrated into Automated Endo-
scope Reprocessors (AERs)/Washer-Disinfectors (WDs). It must be recognized that PENTAX does not
evaluate non-PENTAX leak tester systems to satisfy their specific products claims, for their effectiveness
to accurately detect leaks and/or for their compatibility with PENTAX endoscopes. Insufficient pressures
may adversely affect the endoscope, especially if pressurization occurs during automated reprocessing
at elevated temperatures. PENTAX accepts no responsibility for use of non-PENTAX leakage testers.
Users should check with the leakage tester manufacturer and confirm their specific product claims,
including compatibility with PENTAX endoscopes at various temperatures and their ability to detect leaks
with/without fluid immersion and with/without flexing of the scope’s distal bending section.
CAUTION:
To avoid further damage to the endoscope or the possibility of malfunction during a procedure, do not
use an endoscope with any abnormalities or outward signs of damage.
WARNING:
All instruments must be reprocessed prior to first time use, after any repairs/service and before every
patient use. When utilizing chemo-thermal processes for reprocessing the endoscope, the instrument
should be allowed to return to room temperature prior to use and/or further handling.
