Disinfection system
A disinfection system is provided. The disinfection system may utilize ultraviolet light and/or ozone for disinfection of infected tissue. For example the system may involve an endoscopic ultraviolet light to disinfect lung tissue. In another aspect, the system may involve a ventilator which provides ozone in small doses to disinfect the tissue. Combinations and variations are further disclosed.
1. A disinfection system forming ultraviolet light barrier to
separate a first area and a second area comprising:
a UV light source in a housing, the disinfection system configured such that a plane of UV light is emitted from the housing through a narrow opening defined by the housing;
wherein the first area is defined on a first side of the plane of UV light, and the second area is defined on a second side of the plane of UV light, such that an infectious material passing through the plane of UV light is weakened, deactivated or destroyed; and
a second housing separate from and spaced apart from the housing, the second housing comprising a mirror which is perpendicular to the plane of UV light emitted from the housing, operable to reflect the UV light back towards the housing, and thereby increase the intensity of the UV light.
2. The disinfection system of claim 1 wherein an opening of the housing defining a cross sectional shape of the plane of UV light.
3. The disinfection system of claim 1 wherein the housing is oriented horizontally.
4. The disinfection system of claim 1 wherein the housing is movable.
5. The disinfection system of claim 1 wherein the housing comprises a mirror assembly to reflect light from the UV light source, and wherein the housing is operable to direct UV light from the UV light source in one direction along a length of the housing.
6. The disinfection system of claim 1 wherein the housing and second housing are attached to a side of a chair, the housing positioned at a top of the chair, and the second housing positioned below the housing at a bottom of the chair, the disinfection system operable to form the plane of UV light as a curtain on the side of the chair.
7. The disinfection system of claim 6 further comprising a top housing, the top housing comprising a UV light source positioned to direct a plane of UV light over a top of the chair, above the chair.
8. The disinfection system of claim 7 further comprising a second top housing opposite to the top housing and aligned with the plane of UV light over the top of the chair, the second top housing comprising at least one of a UV light source positioned to direct UV light in the plane of UV light, and a mirror operable to direct the plane of UV light from the housing UV light source back to the top housing in the same plane of UV light over the top of the chair.
9. The disinfection system of claim 6 further comprising four top housings formed in a rectangle defining the plane of UV light over the top of the chair, at least one of the four top housings comprising the top housing having the UV light source positioned to direct the plane of UV light over the top of the chair, the plane of UV light bounded on four sides by the four top housings.
10. The disinfection system of claim 1 wherein the plane of UV light is afocal UV light.
11. The disinfection system of claim 1 wherein the housing comprises at least one of a mirror and a lens to form the plane of UV light as afocal UV light.
12. The disinfection system of claim 1 further comprising a battery power source to activate the UV light source.
13. The disinfection system of claim 1 wherein the housing is formed as a closed shape to define a closed area, and comprising a plurality of UV light sources, the plane of UV light emitted along a majority or all of the closed shape defined by the housing.
14. The disinfection system of 13 wherein one of the plurality of UV light sources forms a plane of UV light across an opening defined by the housing, so as to further isolate a volume from pathogen infiltration, the volume defined on a bottom by the floor, on a sides by the UV light plane, and on a top by the plane of UV light across the opening defined by the housing.
15. The disinfection system of claim 14 wherein the system is located in a hospital operating room and comprising a hospital bed within the volume.
16. The disinfection system of claim 14 further comprising a suction system adjacent to the UV light source, the suction system operable to draw air out of the volume, the air containing at least one of pathogens, deactivated pathogens, or dead pathogens.
17. The disinfection system of claim 1 further comprising a plurality of housings each containing a UV light source, wherein the plurality of housings are positioned above a floor, and the UV light directed downward towards the floor so as to create an isolated UV curtain surrounding an area on the floor.
