Title:
STERILIZATION DEVICE, STERILIZATION METHOD, AND STAPHYLOCOCCUS AUREUS STERILIZATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/077817
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a sterilization device capable of sterilizing and disinfecting to eliminate an organism to be sterilized from the surface of biological tissues while mitigating damage to animal cells, and of ensuring that an irradiation site can be made visually identifiable and thus permit a full awareness of an ultraviolet irradiation area, by means of irradiating with both ultraviolet light for UV sterilization and visible light having high color rendering properties; and a sterilization method. This sterilization device is characterized by: being provided with a light source unit for emitting light having a continuous spectrum over a wavelength range from 200 nm to 500 nm, and a filter which cuts light within a wavelength range of 230 nm (exclusive) to 400 nm and attenuates light within a wavelength range of 400 nm (exclusive) to 500 nm; and the light that passes through the filter being emitted at a living body. The filter preferably satisfies the following condition: for the light that passes through the filter, the ratio of light within a wavelength range of 400 nm (exclusive) to 500 nm to light within a wavelength range of 200 nm to 230 nm is 0.18 or less.
