(1) OF-B179
(2) O-Ring OF-B181
Figure 2.14
a) Prior to use, the suction control valve (OF-B179) should be inspected. Remove
the valve from the control body and make sure that the O-rings are not damaged
or worn.
WARNING:
Worn or damaged valves and/or O-rings should be replaced with new ones which
have already been subjected to a cleaning and high-level disinfection or sterilization
procedure prior to use (O-ring set, model OF-B181, is optionally available). Failure
to do so could result in continuous aspiration which in certain clinical situations can
suction tissue into the distal channel opening at the endoscope tip and/or create a

risks.
b) Connect suction tubing from an external suction source to the suction nipple
located on the control body. Place the distal tip of the endoscope in a basin
of sterile water and press the suction control valve. Water should be rapidly
aspirated into the suction system collection container.

- Before reprocessing and or immersion in any fluids pentax endoscopes should be tested for the loss of integrity in their watertight construction by using pentax brand leak testers for specific details on pentax recommended leak detection procedures please refer to the instructions supplied with pentax leak testers 12
- Inspection of the insertion tube a check the entire surface of the insertion tube for abnormal conditions such as dents crush marks wrinkles bumps buckles excessive bending protrusions 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 12
- Inspection of angulation controls slowly manipulate the angulation control lever to see that it functions smoothly be certain that a full and appropriate range of angulation is possible 18
