PORTABLE ANTIMICROBIAL ULTRA VIOLET STERILIZER
First Claim
1. A portable sterilizer comprising an enclosure defining a chamber having space therein and an entrance door for receiving articles to be sterilized according to a particular sterilization program of exposure of the articles to ultraviolet radiation and ozone gas, a UVC supply arranged to supply germicidal UVC radiation into said chamber, an ozone supply arranged to supply ultraviolet radiation into said chamber at an oxidizing wavelength such that ozone is produced, a power source and a controller arranged to control operation of said sterilizer.

Abstract
The present invention relates to a sterilization unit consisting of a cubical enclosure which uses a sequenced supply of ozone and ultraviolet radiation in the C band (UVC) wave length to sterilize. In use, an article to be sterilized is positioned atop a glass plate mounted between two sources of UVC radiation sources and ozone is first supplied to the enclosure for a period of 15 seconds to 60 minutes followed by a supply of UVC radiation for a period of 15 seconds to 60 minutes.

19. A portable sterilizer comprising:
-
an enclosure defining a generally rectangular chamber having space therein for receiving articles to be sterilized according to a particular sterilization program of exposure of the articles to ultraviolet radiation and ozone gas, wherein at least a wall of said chamber comprises an entrance door, an interior surface of said chamber comprises a material that is reflective of and opaque to ultraviolet radiation, and each corner of said chamber is curved to enhance scattering of said ultraviolet radiation, a UVC supply arranged to supply ultraviolet radiation at wavelength of from about 253.7 to about 254.3 nm into said chamber, an ozone supply arranged to supply ultraviolet radiation at wavelength of about 185 nm into said chamber, a support shelf formed of silica or quartz glass or sapphire plate disposed substantially centrally of said chamber, wherein said support shelf receives said articles for sterilization and transmits at least 55% of UVC radiation, a power source, a controller arranged to control operation of the portable sterilizer and having a non-volatile memory operably connected to said controller, a user input/output interface, wherein said user input/output interface enables communication between said controller and a device selected from a group consisting of a computer, a touchpad, a key pad, a monitor, a digital display, an MP3 player, an MP4 player, an ipod, an ipad, a finger print reader, a security card reader, an entry code reader, and a smart phone, and a visual display operably connected to said controller and providing a representation of an output from said controller wherein said output comprises result data of said sterilization program, wherein said ozone supply supplies ultraviolet radiation at about 185 nm for a first predetermined duration ranging from 15 seconds to 60 minutes and said UVC supply sequentially supplies ultraviolet radiation at about 253.7-254.3 nm for a second predetermined duration ranging from 15 seconds to 60 minutes.

20. A method for sterilizing an article comprising the steps of:
-
placing said article in an enclosure defining a generally rectangular and generally airtight chamber having space therein for receiving articles to be sterilized, exposing said article to ozone gas in said chamber for a period of from about 15 seconds to about 60 minutes at a rate of about 0.25 grams to about 10 grams per hour, and exposing said article to UVC radiation in said chamber for a period of from about 15 seconds to about 60 minutes at a rate of about 100 microwatts to about 800 microwatts per square centimeter at one meter from a UVC source irradiating at a wavelength of about 254 nm. - View Dependent Claims (21, 22, 23, 24)
