PROBLEM TO BE SOLVED: To provide a hydrogen peroxide gas sterilization apparatus that can achieve a desired sterilization all the way through the inside of an object to be sterilized even if the object to be sterilized is, for example, a long object such as a tube or pipe.SOLUTION: The hydrogen peroxide sterilization apparatus includes a sterilization tank 2 for containing an object to be sterilized, a heating means for heating the inside of sterilization tank 2, an evacuation means 3 for evacuating the inside of sterilization tank 2, a pressure-restoring means 4 for pressure-restoring the inside of sterilization tank 2 with air, and a gas supply means 5 for supplying hydrogen peroxide gas into sterilization tank 2. The gas supply means 5 includes a carburetor 14 for hydrogen peroxide solution. The heating means heats and maintains the inside of sterilization tank 2 to a preset temperature, as well as the evacuation means 3 evacuates the inside of sterilization tank 2, followed by the gas supply means 5 supplying hydrogen peroxide gas into sterilization tank 2 and sterilizing the object to be sterilized. The temperature within carburetor 14 was kept lower than the preset temperature within sterilization tank 2.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】被滅菌物がたとえばチューブやパイプのような長物であっても、被滅菌物の奥まで所期の滅菌を図ることが可能な過酸化水素ガス滅菌装置を提供する。【解決手段】被滅菌物が収容される滅菌槽2と、滅菌槽2内を加熱する加熱手段と、滅菌槽2内を減圧する減圧手段3と、滅菌槽2内を空気で復圧する復圧手段4と、滅菌槽2内へ過酸化水素ガスを供給するガス供給手段5とを備える。ガス供給手段5は、過酸化水素水の気化器14を備える。加熱手段により滅菌槽2内を設定温度に加熱して保持すると共に、減圧手段3により滅菌槽2内を減圧後、ガス供給手段5により滅菌槽2内へ過酸化水素ガスを供給して被滅菌物を滅菌する。気化器14内の温度を滅菌槽2内の前記設定温度よりも低くした。【選択図】図1
