ABSTRACT:
A method for sterilizing objects to be sterilized is disclosed, in which an object to be sterilized such as a hand piece is preliminarily brought into a wetted state, and then accommodated and air-tightly closed up within a sterilizing chamber communicated with an oxygen cylinder, oxygen fed from the oxygen cylinder is introduced into an ozonizer to produce ozonized oxygen gas having an ozone concentration of at least 10000 ppm, preferably 15000 ppm or higher, then the ozonized oxygen as is made to pass through the sterilizing chamber after it has been heated up to perfectly replace air within the sterilizing chamber by the ozonized oxygen gas, also moisture adhered to the objects to be sterilized is partly evaporated, subsequently the communication between the sterilizing chamber and the oxygen source is interrupted, the ozonized oxygen gas is circulated through the sterilizing chamber and the ozonizer while it is heated up at the inlet of the sterilizing chamber to thereby enhance the ozone concentration up to at least 20000 ppm, preferably up to 30000 ppm or higher without consuming oxygen, and meanwhile, bacteria adhered to the objects to be sterilized are sterilized surely in a short period of time by the ozone gas under an inflated and wetted condition of the bacteria.
