Provided herein are portable ultraviolet (UV) devices, systems, and methods of use and manufacturing same. Methods of use include methods for UV disinfection and sterilization, more specifically, methods for UV disinfection and sterilization of a container, a room, a space or a defined environment. The portable UV devices, systems and methods are particularly useful for the UV disinfection and sterilization of a container, a room, a space or defined environment used in the food, beverage and dairy industry and in the process of fermentation for an alcoholic beverage. Provided are also portable UV devices, systems, and methods for inhibiting the growth of one or more species of microorganisms present in a container, a room, a space or a defined environment, preferably for inhibiting the growth of one or more species of microorganisms present on an interior surface of a container, a room, a space or a defined environment.

The present invention provides an apparatus for diffusing a chemical substance comprising: a chamber having a diffusing member arranged to diffuse a chemical substance to air disposed within the chamber, wherein the chamber is in communication with an air-inlet arranged to receive air from an exterior of the chamber and an air-outlet arranged to expel air from within the chamber.

Provided is a decontamination apparatus for decontaminating an enclosed room. The decontamination apparatus includes a source including a UVC bulb and a reflective shield arranged adjacent to the UVC bulb and configured to reflect UVC light emitted by the UVC bulb toward a region of the enclosed room to be decontaminated. A mounting system that is adjustable secures the source at a desired location within the enclosed room. A controller is operatively-connected to the source to terminate operation of the UVC bulb in response to a determination that an occupant is present within the enclosed room.

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.

An obturator can include antimicrobial features which assist in sterilizing or maintaining the sterility of fluid contained within a vascular access device while the device is not being used for infusion or other access to the patient's vasculature. These antimicrobial features include antimicrobial coatings applied to various surfaces of an obturator and antimicrobial components bonded or otherwise secured to an obturator. Various combinations of antimicrobial coatings and/or components can be used on an obturator as necessary to provide a desired amount of antimicrobial agents within a particular enclosed volume of a vascular access device.
