According to the second embodiment of the present invention, the operating room 1
When the number of germs in the inside reaches the upper limit set value, the germ detection sensor 15
The ozone generator 13 is driven by detecting this, and air containing ozone is blown into the operating room 1. Thereby, the inside of the operating room 1 can be sterilized by the sterilizing action of the strong oxidizing power of ozone. As a result, the germs in the operating room 1 can be killed and the number of germs in the operating room 1 can be reduced.

Next, when the number of germs in the operating room 1 reaches the lower limit set value, the germ detection sensor 15 detects it and the ozone generator 13 is stopped, and the sterilization in the operating room 1 is stopped.

Thereafter, by repeating the above operation, the number of germs in the operating room 1 is maintained between the upper limit set value and the lower limit set value.

Therefore, in the second embodiment of the present invention, as in the first embodiment, when a medical person such as a doctor or a nurse enters the operating room 1, the human body is sterilized by the strong oxidizing power of ozone. When adhering to the operating room 1, medical personnel can take an air shower, wash their hands with a disinfectant, or press adhesive tape on clothes when entering the operating room 1, as in the past.

For example, in the above embodiment, ozone is blown out of the air outlet 5 into the operating room 1 as it is, but a mist outlet of a mist generator that atomizes and jets water into the air outlet 5 is connected. Alternatively, the ozone may be blown into the operating room 1 from the air blowout port 5 with ozone attached to the mist blown out from the mist blowout port of the mist generator. Since the ozone is quickly dropped onto the floor of the operating room 1 by blowing the ozone with the ozone adhered to the mist, the ozone can be intensively applied to the floor of the operating room 1.

The air outlet 5 is connected to a bubble outlet of a bubble generator for bubbling and jetting water, and the air is blown in a state in which ozone is confined in the bubbles jetted from the bubble outlet of the bubble generator. It may be blown out from the mouth 5 into the operating room 1. In this way, by blowing ozone in a state of being confined in the air bubbles, when the air bubbles reach the surface to be sterilized and burst, the ozone of an appropriate concentration generated by the ozone generator 13 is directly sterilized without being diluted. Acts on the surface for efficient sterilization.

In the above embodiment, the air outlet 5 for blowing out ozone is provided on the ceiling of the operating room 1. However, if the ozone is blown out to all corners of the operating room 1, the surgical operation may be performed. It may be provided at any position in the room 1. Since ozone has a higher specific gravity than air,
The air outlet 5 is preferably provided in the upper part of the operating room 1.

Further, in the above embodiment, the operating room 1 of the hospital
Although it is applied to sterilization of hospitals, it can also be applied to sterilization of newborn rooms in hospitals, toilets, toilets, bathrooms, garbage storage, clean rooms of biomedical laboratories and food factories.
