Document Type and Number:
WIPO Patent Application WO/2021/192330
Kind Code:
A1
Abstract:
This sterilization method includes: a preliminary pressure-reduction step (S200) for housing, in a chamber (11), a sterilization target packaged with a packaging material in which a material that adsorbs ozone gas and hydrogen peroxide is used, and then reducing the pressure inside the chamber (11) relative to the atmospheric pressure; an ozone adsorption step (S300) for injecting ozone gas into the chamber (11) under the reduced pressure at the preliminary pressure-reduction step (S200) to cause the packaging material to adsorb the ozone gas; and a sterilization step (S500) for sterilizing, following the ozone adsorption step (S300), the sterilization target using the ozone gas and the hydrogen peroxide.
