When performing ethylene oxide gas sterilization of this product, detach
the connector cap from the probe connector. If sterilization is performed
while the connector cap is placed on the probe connector, sterilization will
be incomplete and may pose an infection risk.
This product must be properly aerated after ethylene oxide gas
sterilization to remove toxic components. Gas remaining in this product
after ethylene oxide gas sterilization may harm human body.
CAUTION
In order to successfully sterilize this product by ethylene oxide gas
sterilization, use the parameters described in “Table 7.2 Conditions of
20% ethylene oxide gas sterilization (chamber type).” Exceeding the
recommended conditions may cause equipment damage.
