Abstract
The present invention provides an infection prevention device and an infection prevention method including a light source 11 for radiating light in specific wavelength range, and a beam-firming optical element 12 for forming the light radiated from the light source 11 on a radiant film 20 having a predetermined width, wherein pathogenic microorganism which levitates together with airborne droplets or particles or which levitates alone is inactivated or killed by the radiant film 20 formed in air, or moisture of the airborne droplets or the particles is evaporated. According to this, pathogenic microorganism which levitates in air can be inactivated or killed in air.
Claims24
An infection prevention device comprising
- a light source for radiating light in specific wavelength range, and
- a beam-firming optical element for forming the light radiated from the light source on a radiant film having an adjustable width, wherein
- pathogenic microorganism which levitates together with airborne droplets or particles or which levitates alone is inactivated or killed by the radiant film formed in air, or moisture of the airborne droplets or the particles is evaporated.
An infection prevention device wherein
- a lamp, a light-emitting diode or a semiconductor laser is used as a light source which radiates light in specific wavelength range, and
- pathogenic microorganism which levitates together with airborne droplets or particles or which levitates alone is inactivated or killed by forming, in air, a radiant film having an adjustable width by the light radiated from the light source.
An infection prevention method wherein a radiant film having an adjustable width is formed by light in a specific wavelength range, pathogenic microorganism which levitates together with airborne droplets or particles or which levitates alone is inactivated or killed, or moisture of the airborne droplets or the particles is evaporated.
