PURPOSE:To prevent secondary infection in a hospital by a process wherein after a treating tank wherein a specimen to be sterilized is stored is sealed, gas in the treating tank and a steam generating apparatus are evacuated through a bacteria elimination mechanism and a high temp. and high pressure steam is, fed into the bacteria elimination mechanism and the treating tank to keep insides of the bacteria elimination mechanism and the treating tank under a high temp. and high pressure condition. CONSTITUTION:A specimen 4 to be sterilized is stored in a treating tank 1, which is then sealed and gas in the treating tank 1 and a steam generating apparatus 2 is evacuated through a bacteria eliminating apparatus 16 and feeding water in the steam generating apparatus 2 is preheated and predeaerated. Then, a high temp. and high pressure gas is passed through the bacteria eliminating apparatus 16 to keep a high temp. and high pressure condition and both sterilization treatment of the bacteria eliminating apparatus 16 and preheating of the treating tank 1 are performed. Then, a high temp. and high pressure steam is fed into the treating tank 1 to keep a high temp. and high pressure condition and the specimen 4 to be sterilized in the treating tank 1 is sterilized and the high temp. and high pressure steam in the treating tank 1 is discharged under vacuum and cooling through an exhaust pipe to reduce the pressure in the treating tank 1 and to cool it by introducing a cooling water. |
