A shielding structure of an object sterilized by radiation. The object is a housing that accommodates an accommodated object therein and is formed of a shielding material that shields the radiation and secondary radiation that has a higher transparency than the radiation and is secondarily generated by the radiation, an exterior of the housing is sterilized by the radiation, and the radiation and the secondary radiation do not penetrate through the accommodated object.

An apparatus for treating air includes a housing with an air inlet and an air outlet, the housing enclosing an air treatment zone and an ozone removal zone, wherein the ozone removal zone is positioned downstream of the air treatment zone with respect to a flow direction of the air being treated, an ozone generator in the air treatment zone configured to generate ozone from the air, wherein the ozone generated by the ozone generator treats the air in the air treatment zone, catalyst in the ozone removal zone that removes at least a portion of the ozone generated the ozone generator, a particle matter (PM) filter positioned between the air treatment zone and the ozone removal zone, wherein the ozone generated by the ozone generator treats the PM filter, and an air mover positioned near the air outlet configured to draw the air through the air inlet.

System and method to reducing risk of patient infections (HAI), using operating rooms equipped with suitable automatic airborne sterilizing agent generators, sensors, mechanisms, automatic air control devices, and ceiling mounted structures that allows the room to both provide air curtains of laminar flow sterilized air over the operating table, as well as to be quickly and completely sterilized. After suitable safety checks, the system isolates the interior air from external air, and activates an air phase anti-microbial agent generator, filing the room with air-phase anti-microbial agent. After sterilization, the invention deactivates the generator, removes the remaining air-phase anti-microbial agent by flowing room air through a catalytic converter, and then restores the connection to outside sterilized air. The ceiling mounted structure is configured for laminar flow air curtain delivery, supply lighting, and support boom mounted operating room equipment. Various sensors, control methods, wall coverings, and other options are disclosed.

A method and a device for disinfecting inner surfaces, for example, of freezers and the like includes the production of a microfilm of sanitizing solution on the inner surfaces and on the devices contained in the freezers and the like, by a method which comprises two sequential steps, a first step in which 100% of the inner surface of the internal environment of the freezer or the like is completely saturated with a mist of sanitizing solution, which is then condensed, and a second step in which the air containing this mist is passed through a filter provided with means that absorb the sanitizing solution, both steps being implemented by closed-loop recirculation means (looping).

The present invention has as its object the provision of an ozone generator that can generate ozone with high efficiency. The ozone generator of the present invention includes: source gas supply means for supplying a source gas containing oxygen; a gas flow channel forming member for forming a gas flow channel through which the source gas from the source gas supply means flows; and an ultraviolet light source for emitting ultraviolet light, the ultraviolet light source being disposed in the gas flow channel. The ozone generator irradiates the source gas flowing through the gas flow channel with the ultraviolet light from the ultraviolet light source to cause the oxygen in the source gas to absorb the ultraviolet light and thereby generate ozone. The ultraviolet light source comprises an excimer lamp for emitting ultraviolet light with a wavelength of not more than 200 nm. A flow rate of the source gas in a region where the ultraviolet light source is disposed in the gas flow channel is not lower than 0.1 m/s.

Embodiments of the present disclosure generally relate to devices and methods for sterilizing equipment. More particularly, one or more embodiments described in the present disclosure are directed to portable devices for sterilizing medical equipment in emergency situations. The sterilization devices and method of the present disclosure address an unmet need for sterilizing surgical equipment in a manner that is not only effective and time-efficient, but is also portable and reliable enough to use in emergency medical situations in remote locations where modern sterilization equipment is not available.

The present invention relates to a device that eliminates germs and bacteria from your hands. The device is especially designed to achieve total asepsis of the hands of people working and/or should have access to certain sectors of industries manufacturing and/or fractionation of food, medicinal products, testing laboratories industry biological, chemical industries in general, operating rooms, etc. where it is required to maintain strict hygiene and asepsis conditions.

A sterilization system including an oxygen generator, an ozone generator, a mixer, a wash chamber, and a sterilization chamber is disclosed. The oxygen generator is configured to generate a flow of oxygen. The ozone generator is in fluid communication with the oxygen generator, and configured to generate a flow of ozone from the flow of oxygen. The mixer is in fluid communication with the ozone generator and configured to receive the flow of ozone and a flow of cleaning fluid, and mix the flow of ozone into the flow of cleaning fluid, resulting in a flow of ozonated cleaning fluid. The wash chamber is in fluid communication with the mixer and configured to receive the flow of ozonated cleaning fluid from the mixer. The sterilization chamber is in fluid communication with the ozone generator and is configure to receive the flow of ozone.

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.

The present invention extends to methods, apparatus, and systems for disinfecting articles with ozone. Aspects of the invention use increased concentrations ozone in sealed, confined volumes, such as, for example, carts, lockers, cabinets, etc. to disinfect or sterilize medical articles. A medical article is placed in a confined volume. The confined volume is sealed so that the atmosphere inside the sealed, confined volume is isolated from the external atmosphere. The concentration of ozone in the sealed, confined volume is rapidly increased to a threshold concentration. At the threshold ozone concentration, the medical article can be disinfection or sterilized in a reduce amount of time. When disinfection or sterilization is complete, the concentration of ozone in the sealed, confined volume is rapidly reduced to a safe level. The sealed, confined volume is unsealed. The disinfected or sterilized medical article can be removed from the confined volume.
