OSF-3 ENDOSCOPE REPROCESSING MANUAL
• The results of sterilization depend on various factors such as
how the sterilized instrument was packed or the positioning,
method of placing and loading of the instrument in the
sterilization device. Please verify the sterilization effects by
using biological or chemical indicators. Also follow the
guidelines for sterilization issued by medical administrative
authorities, public organizations or the infection management
sections at each medical facility, as well as the instruction
manual of the sterilization device.
• All instruments must be properly aerated following ETO gas
sterilization to remove toxic ethylene oxide residuals.
• Install the ETO Cap on the Venting Connector of the
Endoscope Connector before ETO gas sterilization as shown
in Figure 2.1. If ETO gas sterilization is performed while the
ETO Cap is removed, air inside the Endoscope will expand
and could rupture the covering of the Bending Section.
• Repeated ETO gas sterilization procedures will gradually
deteriorate the instrument. Do not ETO gas sterilize the
instrument unnecessarily.
ETO gas sterillization is not permitted in some European
countries.
