Apparatus, system, and methods are provided for reducing infectious agents at a sterile site by preventing infectious agents from coming into contact with the sterile site. A barrier is produced for infectious agents that may come in proximity or otherwise communicate with the site. The apparatus is configured to create a void-free barrier in which infectious agents are reduced with minimal exposure of potentially harmful effects of the barrier to the sterile site, objects, or users of the apparatus.

A multi-layer bag comprising a porous portion configured to allow a sterilizing gas to penetrate into the bag and a gas-impervious portion, characterized in that the gas-impervious portion comprises an outer layer, an inner layer and an intermediate layer integrally formed together so that the intermediate layer is sealingly enclosed between the outer layer and the inner layer so as to be physically isolated from inner and outer environment of the bag, and the intermediate layer comprises a matrix and at least one pigment distributed within the matrix, the pigment being configured to change at least one optical property in reaction to an environment change resulting from a damage of the outer and/or inner layer.

The present invention relates generally to the field of sanitation equipment. More specifically, the present invention relates to a shopping cart sanitation system that sanitizes shopping carts, baskets and bins that pass therethrough. The system is comprised of a tunnel-like enclosure that is comprised of a sanitization chamber and a drying chamber, wherein the sanitization chamber sanitizes carts via a spray nozzle system that sprays disinfectant as well as a plurality of UV disinfecting lights. The drying chamber dries the carts, baskets and bins via a plurality of fans before the carts exit the station and are ready for use. In one embodiment, the system may further comprise an antimicrobial station.

A portable communication device includes an apparatus for environmental sensing. The apparatus includes a housing, one or more environmental sensors and an ozone source. The housing includes one or more ports for allowing air flow between the surrounding environment and a cavity of the housing. The environmental sensors are coupled to the housing and can sense an environmental agent included in the air flow. The ozone source can generate ozone gas within the cavity of the housing to decompose unwanted organic compounds inside the port.

An apparatus for sanitising a target comprises a supply of a sanitising substance comprising a gas and/or plasma of nitric oxide and/or ozone, and a conduit arranged to direct the sanitising substance onto a target to sanitise the target. FIG. 13(a) shows a sanitiser product generator device 1200 which is arranged to release a sanitising product into an elevator 1220 via channel 1240. The sanitising product will destroy bacteria and virus within a mixing chamber before being released back into the lift shaft and lift cabin free from contaminants and may permeate the entire enclosed volume of the elevator, thereby destroying bacteria and virus in the air and on the surfaces of the elevator, circulating clean air and cleaning any contaminated air incoming via opening of the elevator doors or from passengers coughing and sneezing, for example.

A mobile body is configured to travel an area optionally over a surface inside an aircraft cabin. Components comprise at least one of a UVC protective shield, the shield selectively providing a multisided enclosure that selectively envelopes and/or separates the operator from the UVC in the surrounding environment. A source of UV radiation is mounted to the mobile body and configured to direct UV radiation to the surface at a predetermined dosage. At least two articulated arms are mounted to the mobile body, and UV lamps mounted respectively on the arms. The mobile body is a trolley or cart for negotiating an area optionally an aircraft aisle.

A light fixture devised to provide illuminated sign panes for displaying information to nearby viewers, but including both white light-emitting diodes (LEDs) and UV-C LEDs. The white LEDs are arranged in the fixture so as to illuminate transparent/translucent panes upon which helpful information is displayed, when actuated. The UV-C LEDs also are arranged in the fixture so as to disinfect or sterilize the ambient air near the fixture. The illumination LEDs and the disinfection LEDs are independently switchable “on” and “off,” so that a user can controllably illuminate the informational panes, or disinfect the air, or both.

An UV disinfection system (200) may feature a chamber (207) with internal spherical reflective surfaces (208) to evenly reflect UV radiation from all angles to direct the UV radiation to all surface area of the object inside the chamber to disinfect object utilizing UV radiation under controlled time. An object (215) to be disinfected may reside within the chamber (207) on a UV transparent rack or shelf (214). The spherical reflective surfaces may be fashioned by placing such surfaces on a polyhedral internal structure or making the internal chamber spherical in and of itself (208). Multiple UV sources (209a), (209b) may also be utilized.

Systems and methods for detection, treatment, prevention and protection are shown and described. UVC may be used in such applications.

An ultraviolet germicidal irradiation (UVGI) room analysis method and system combines the medical knowledge of UVGI disinfection and UVGI photometric analysis to generate a visual report that demonstrates the exposure time needed from an UVGI source at one or more locations within a room or other environment to effectively disinfect a specific microorganism, such as a germ or a virus, from each targeted surface in the room.
