Abstract

This invention relates to a method, process and apparatus for disinfecting and sterilizing all types of surfaces contaminated with microorganisms and toxic substances to render both inactive. Furthermore, this invention relates to both a method and apparatus for disinfecting and/or sterilizing breathable air and then using this air to protect a confined space from external contamination. The apparatus consists of a new ultra-violet (NUV) source that is more effective than mercury based 254 nm light for destroying DNA of virus, bacteria, spores and cysts. It is most effective in breaking chemical bonds in toxic gases and Biotoxins that are useful to terrorists. It is combined with other apparatus that remove particulates and byproducts sometimes produced by the NUV source and maintains positive pressure of the confined space so as to prevent the influx of air from outside the protected zone.

IPC Classes  ?

• A61L 2/10 - Ultraviolet radiation
• A61L 2/00 - Methods or apparatus for disinfecting or sterilising materials or objects other than foodstuffs or contact lensesAccessories therefor
• A61L 9/20 - Ultraviolet radiation
• B08B 17/00 - Methods preventing fouling
• A23B 7/015 - Preserving by irradiation or electric treatment without heating effect
• A23L 3/28 - Preservation of foods or foodstuffs, in general, e.g. pasteurising, sterilising, specially adapted for foods or foodstuffs by irradiation without heating with ultraviolet light

Abstract

This specification relates to an improved method, process and apparatus for disinfecting and sterilizing all types of surfaces and indoor air and room air contaminated with microorganisms. The improved apparatus consists of a multi-wavelength narrow spectral width UV source that is more effective than mercury based 254 nm germicidal lamps for destroying the DNA and outer shell or membrane of virus, bacteria, spores and cists.

IPC Classes  ?

• G01N 21/33 - Investigating relative effect of material at wavelengths characteristic of specific elements or molecules, e.g. atomic absorption spectrometry using ultraviolet light
• G21K 5/00 - Irradiation devices
• A61L 2/10 - Ultraviolet radiation
• A61L 9/20 - Ultraviolet radiation
