Chapter 7 Cleaning, Disinfection and Sterilization Procedures for Endoscopic Instruments
VISERA RHINO-LARYNGO VIDEOSCOPE ENF-V2
• Do not store disinfected instruments. Use them immediately
after disinfection or forward them to the following sterilization
process. If stored instruments are used, refer to your local
regulations and/or guidelines.
• Do not immerse instruments for more than 60 minutes in any
liquids. If instruments are left immersed in liquids for a longer
period, too much humidity inside of the endoscope will arise,
which will cause malfunction.
When the regulation/guideline in your region requires
disinfection prior to sterilization for the personnel in charge of
reprocessing, perform the sterilization after the procedure of
Section 6.6, “Automatic cleaning/disinfection” on page 41 or
Section 7.7, “Disinfection” on page 63.
7.3
Precleaning
Preclean the endoscope immediately after the procedure. The following steps
are to be performed when the light source and the video system center are
turned OFF.
Endoscopic instrumentation must be meticulously cleaned
prior to disinfection or sterilization. Thorough cleaning
removes both micro-organisms and organic material. Failure
to remove organic material decreases effectiveness of the
disinfection or sterilization procedure. If the endoscope is not
immediately precleaned, residual organic debris will dry on
the instrument and effectively reprocessing will be difficult.
