6. Leak test:
Warning:
An leak test must be performed before
each immersion in fluid, during cleaning and
disinfecting. If the leak test is positive (detected
perforation, i.e. the
endoscope must not be further prepared. The test
should be repeated if necessary. The outer casing
must be wiped with instrument disinfectant or 70
% isopropanol. The endoscope is enclosed in a
protective film sheathing, packed in the shipping
crate and passed to the service workshop with
the remark "leaky, not disinfected".
Before fitting the leak tester (see Fig. 8) to the
relevant connection, make sure that the two
connecting parts are completely dry. Never connect
or remove the leak tester under water. To connect
the leak tester correctly (see Fig. 9), guide the
connector centrally onto the connection, aligning the
pin located on the side of the connector (also visible
from the outside) with the groove located on the
connection. Then press the connector towards the
endoscope and rotate sideways approx. 90º, until it
re-engages effortlessly at the top. The plug-in
connection must not now be removed. The leak tester
is pumped up to a range between 140-160 mmHg
and observed for approximately 20 seconds. If the
pressure drops continuously, the leak tester may not
be correctly connected. If the compressed air
pressure drops despite correct connection, then the
endoscope is leaky and must not be immersed in
fluid.
The imperviousness meter is then removed and the
endoscope completely immersed in water.
Attention: The imperviousness meter is not
immersed with the endoscope.
If a leaky point exists (detectable through constantly
rising air bubbles), the endoscope should be
removed from the water immediately. In order to
detect any holes on the flexible distal end, it should
be moved up and down with the U-bend adjuster:
If small air bubbles have formed on the indentations
on the outside of the endoscope, these can be
eliminated by light knocking. If air bubbles still rise
continuously, the endoscope is not tight and must be
removed from the water immediately.
If the leak test on the endoscope has a negative
result (no perforation
endoscope from the water and unscrew the leak
tester. The endoscope can then be immersed in the
cleaning liquid or disinfectant.

7. Preparation:
The flexible
autoclavable and must also not be cleaned with
ultrasound.
Clean medical products are a prerequisite for
reliable and effective disinfecting or sterilisation.
Particular importance is therefore attached to
cleaning in the general preparation procedure.
Do not use excessive pressure when cleaning the
insertion tube, so as to avoid causing any
damage. The endoscope must not be immersed
for longer than the maximum time indicated by
the cleaning liquid manufacturer, as the outer
surface and optics may otherwise be damaged,
resulting in the penetration of fluids.
The endoscope
disinfected before each use. The leak test should
also be carried out as specified.
Cleaning and disinfectant solutions must be
carefully removed by intensive rinsing with sterile
distilled water, as they can cause chemical
the
irritations and allergic reactions in the patient's
mucous membrane.
It is important not to use any aldehyde-containing
agents for preliminary cleaning, as these cause
fixing of albumen.
