Sterilization And Aeration
(continued)
2. Following ETO Gas Sterilization, aeration time of 72 hours at room
temperature is required.
3. Aeration Chamber: To shorten the aeration time to 12 hours, an
aeration chamber may be used, provided the temperature does not
exceed 55°C (131°F).
NOTE: Prior to placing the RL-150 Rhinolaryngoscope in an
aeration chamber, the Red ETO Gas Sterilization Vent Cap MUST
be on securely.
Cold Sterilization
For those situations where Ethylene Oxide (ETO) Gas Sterilization capa-
bility is not available, Welch Allyn endoscopes have been designed to
withstand immersion in Glutaraldehyde solution for a maximum of 10
hours to achieve “cold sterilization”. Never fully immerse the instrument
without first conducting the leakage test procedure, as described else-
where in this manual, to verify the watertight integrity of the scope.
WARNING: Never exceed 10-hour maximum immersion.
After 10-hour immersion, the instrument must be thoroughly rinsed to
remove all residual Glutaraldehyde solution.
After being thoroughly rinsed, the instrument must be allowed to
“breathe”, balancing internal and external humidity, by attaching the
Red ETO Venting Cap.
Storage
Thoroughly dry the instrument and accessories. Place in the wall hanger.
1. During storage, the insertion tube of the scope and the light guide
should be kept as straight as possible.
2. The storage area should be dry and airy. Avoid high humidity, high
temperature and areas exposed to direct sunlight.
3. The Red ETO Venting Cap should be placed on the scope to allow
the scope to “breathe”, balancing internal and external humidity, while
it is in storage.
