Welch Allyn RL-150 Rhinolaryngoscope - User Manual - Manual (Page 8)

Operation
Procedure
The methods and techniques of rhinopharynlaryngoscopy are well-defined
and documented. Endoscopy training seminars and programs are also in
existence.
No attempt is made in this manual to outline the medical procedure or
techniques of rhinopharynlaryngoscopy. The physician should always
take care to understand the clinical background of each patient and the
contraindications of the procedure.
Preparation Before Insertion
Note: The endoscope should be properly cleaned and disinfected
or sterilized prior to the first use and all subsequent uses. Only by
adhering strictly to the steps outlined elsewhere in this manual can
the user be assured of the effectiveness of the processes.
1. Gently clean the objective lens with a cotton-tip applicator moistened
with alcohol.
2. Gently wipe the insertion tube with gauze dampened with clean water.
3. The individual user should adjust the diopter adjustment ring to make
sure that a clear view can be obtained. No further adjustment should
be necessary during a procedure.
4. If desired, apply a water-soluble lubricant to the insertion tube. The
objective lens must be kept free of the lubricant which would obstruct
your view.
NOTE: Do not use lubricants that are petroleum based as these will
deteriorate the rubber covering the bending section.
Insertion and Operation
1. Always insert the instrument slowly under direct vision.
2. Once lumen is visible, adjust the light intensity control on the light
source to desired setting.
Note: The distal tip of the rhinolaryngoscope may become warm if
in continuous operation with the illumination set too high; this can
damage the mucosa. Use the lowest light setting possible.
3. Tip deflection must be performed under direct observation. Deflect the
bending section gently using minimal force.
4. When withdrawing the instrument, pull back slowly under direct obser-
vation. Do not remove the instrument “blindly”.
