A sterilization, disinfection, sanitization, or decontamination system having a chamber defining a region, and a generator for creating a free radical effluent with reactive oxygen, nitrogen, and other species and/or a vaporizer. A closed loop circulating system without a free-radical destroyer is provided for supplying the mixture of free radicals from the generator mixed with the hydrogen peroxide solution in the form of the effluent to the chamber. The system is used in sterilizing, disinfecting, sanitizing, or decontaminating items in the chamber or room and, with a wound chamber, in treating wounds on a body. The wound chamber may be designed to maintain separation from wounds being treated. Various embodiments can control moisture to reduce or avoid unwanted condensation. Some embodiments can be incorporated into an appliance having a closed space, such as a washing machine. Some embodiments may include a residual coating device that deposits a bactericidal coating on sterilized items.

Methods of manufacturing a light-activated powder are provided which provide solid-state generation and release of chlorine dioxide without detectable amounts of any toxic by-products such as chlorine gas, chlorites, or chlorates. The powder need not be exposed to moisture, relative humidity, or an acid before or during exposure of the powder to visible light to generate the gas. The powder can also be prepared under conditions that minimize or prevent decomposition or oxidation of sodium chlorite or premature light activation of the powder during the manufacturing process to maximize its activity.

A sanitizing cabinet system includes ozone distribution passaging in open fluid communication with a sanitizing compartment inside a cabinet. An ozone generator and a sanitizing air mover are located in the ozone distribution passaging. The sanitizing air mover moves air from the sanitizing compartment across the generator to form ozonated air and moves the ozonated air from the ozone distribution passaging into the sanitizing compartment. A control system controls the ozone generator and air mover based on feedback from an ozone sensor indicating ozone exposure over time. An ozone conversion device is mounted on a dividing wall of the cabinet outside the sanitizing compartment. The dividing wall has inlet and outlet holes, and the ozone conversion device has upstream and downstream chambers in communication with the inlet and outlet holes. Selectively openable dampers separate upstream and downstream chambers from an ozone conversion chamber in which ozone conversion catalyst is received.

Methods and apparatus for the sanitization, detoxification, disinfection, high level disinfection, or sterilization of both the interior and exterior surfaces of at least one object.

The present invention provides a sterilization apparatus and a sterilization method. The sterilization method includes: an operation in which a sterilant injection block for containing a sterilant and providing a sterilant injection path for injecting the sterilant or a vacuum packaging pouch having the sterilant injection block is mounted inside a vacuum chamber; and an operation in which the vacuum chamber is operated in a chamber mode in which the vacuum chamber is used as a sterilization container when only the sterilant injection block is mounted and the vacuum packaging pouch is operated in a pouch mode in which the vacuum packaging pouch is used as a sterilization container when the vacuum packaging pouch is mounted.

The present invention provides a UV sterilization module capable of suppressing a generation of ozone inside and outside a device, and emitting UV rays having a wavelength of near 200 to 230 nm, in particular UV rays having a wavelength of 222 nm at a high luminous intensity, and a UV sterilization apparatus using the UV sterilization module. According to the UV sterilization apparatus of the present invention, bacteria or viruses existing on a surface of the biological tissue may be selectively UV sterilized without harming animal cells such as human cells, and a generation of ozone harmful to the skin may be reduced.

Apparatus for sterilizing surfaces and apparatus for sterilizing air and enclosed objects using gliding arc discharge technology are described, whereby disinfecting products formed in the discharge are prevented from escaping from the apparatus into the ambient air.

A system for and a method of eliminating a virus within a vehicle. The system includes a sterilizer positioned within a vehicle and configured to eliminate a virus within the vehicle while operating, a detection sensor that detects whether or not an occupant is present within the vehicle, and a sterilization controller that controls operation of the sterilizer with a preset operation profile on the basis of a result of the detection sensor detecting whether or not the occupant is present within the vehicle.

A sterilizing method for sterilizing a sterilization object housed in a chamber 11 includes an ozone preparation step S504 for filling an inside of a buffer tank 34 with ozone gas, and an ozone injection step S505 for injecting the ozone gas filled in the inside of the buffer tank 34 into the chamber 11.

The present invention relates to methods and devices for diminishing microbes. The invention provides methods and devices to sanitize, disinfect and sterilize areas, spaces, surfaces and items as well as to sanitize human skin. The methods and devices will be of major importance to the healthcare industry and to other industries or physical environments that require sanitizing, disinfecting or sterilizing. The methods comprise the use of near infrared light (NIR), UV, violet and blue emitting LED elements as well as OLED (Organic Light-Emitting Diodes) as a stand-alone technology. Optionally the system may be used in combination with ozone and ionized silver.
