The method includes flowing a liquid disinfectant into an indicator device that has a plurality of indicator microorganisms disposed therein, the indicator microorganisms comprising or capable of producing a detectable enzyme activity; contacting the indicator microorganisms with the liquid disinfectant for a predetermined minimum first period of time at a first temperature; after contacting the indicator microorganisms with the liquid disinfectant for the first period of time at the first temperature, contacting the indicator microorganisms for a second period of time with a detection medium comprising a detection reagent; and during or after the second period of time, detecting a quantity of the detectable enzyme activity that was not inactivated by the contact with the disinfectant. The indicator device is also provided.

An isolator system 1 includes: a main isolator 3 in which an aseptic state is maintained and which is for performing an aseptic operation; an incubator 4 in which the aseptic state is maintained and which is connected to the main isolator 3 and is for culturing cells and the like; decontamination means 35 for decontaminating the inside of the main isolator 3; and a decontamination station 9 that decontaminates the inside of the incubator 4. The isolator system 1 further includes a blocking member 30 for sealing a connection port 13 from the outside, the port being provided in the main isolator 3 and being for connection with the incubator 4. When the inside of the main isolator 3 is decontaminated, the connection port 13 is sealed from the outside with the blocking member 30. The isolator system that can efficiently decontaminate the main isolator and the subisolator connected to this main isolator can be provided.

A pulsed xenon UV disinfection system for treating objects present inside a room and/or area surrounding the system. The system includes an head portion, an intermediate portion and a lower portion. The head portion includes a lamp, a housing and a reflector to redirect the UV rays in preferred direction. A shutter mechanism is disposed in the intermediate portion includes a shutter to provide protection to the lamp. A shape changing mechanism comprising second actuator to change shape of reflector as per the treatment conditions and/or physical characteristics of the room. The shape of reflector facilitates to converge or diverge UV rays emitted by the lamp to effectively treat objects/area close to the system or away from the system, respectively.

Embodiments of the invention disclosed herein include devices for sterilizing items, particularly hand-held writing implements, using ultraviolet radiation. Other useful features of the sterilizer embodiments include a no touch proximity sensor for opening the lid to access sterilization ports and any items within the ports, automatic descent of the items into the sterilizer and closure of the lid for a preselected sterilization cycle without the lid binding on the items in the ports.

A portable ultraviolet sanitization device is disclosed that includes a gripping portion, an ultraviolet electromagnetic radiation emitter portion, and a power source. The ultraviolet electromagnetic radiation emitter portion is disposed at a distal end of the gripping portion. The ultraviolet electromagnetic radiation emitter portion includes one or more ultraviolet light sources, such as light emitting diodes or excimer lamps. The power source is in electrical connection with the one or more ultraviolet light sources. The sanitization device is used to sanitize surfaces by eliminating viruses and other microorganisms. The sanitization device is particularly well-equipped to sanitize surfaces that are used intermittently, such as airplane cabins, restaurant seating areas, or similarly occupied spaces.

A system and method for sterilizing one or more high-touch implements, such as shopping carts, using ultraviolet (UV) light within a contained chamber for a specified period of time. In an embodiment, one or more shopping carts may be guided into a sterilization chamber through a front-side opening of an apparatus. Once the shopping cart is in place inside the sterilization chamber, a UV light process may be engaged whereby several UV lights will be turned on to flood the sterilization chamber with UV light. UV light has been shown to be effective at killing bacteria, viruses, mold, and other pathogens with exposure in as little as 5 seconds. The sterilization procedures results in sterilizing a shopping cart for next use as sterilized carts may be collected in a corral designated form newly sterilized shopping intended for next use.

A container for cleaning and sterilizing a menstrual cup includes a vessel with an inner cavity made of elastic material having a bell-shaped portion for collecting menses and gripping means for insertion and removal during menstrual cycle; a lid closing an open-top, the vessel and the lid being made of materials suitable for exposure to microwave radiation, holding means for connecting the menstrual cup to the lid with the gripping means, wherein the lid is reversible for fitting on the open-top in two mounting positions, the first mounting position with the holding means directed towards the inner cavity such that, when attached to the lid, the menstrual cup projects at least partially into the inner cavity, and the second mounting position with the lid reversed and the holding means directed away from the inner cavity such that, when attached to the lid, the menstrual cup projects outwardly.

A sterilizing lamp includes a discharge tube, a ground electrode part, a high-voltage electrode part, a safety cover, and a light shield. The discharge tube is filled with discharge gas for generating excimer light. The ground electrode part and the high-voltage electrode part generate discharge in the discharge tube to excite the discharge gas. The safety cover is made of an electrically insulating organic material and covers the high-voltage electrode part. The light shield is made of an electrically insulating inorganic material and intervenes between the discharge tube and the safety cover to block the excimer light traveling from the discharge tube toward the safety cover.

A sanitation assembly attaches over a surface inside a tray table of an aircraft. A source of UV radiation is mounted to the assembly and configured to direct UVC radiation to the tray table at a predetermined dosage, wherein the assembly uses for disinfection of the aircraft tray table. The embodiments may use UV light sources and/or a disinfection unit powered by a fuel cell or other external power source.

Technologies (e.g., devices, systems and methods) for sanitizing mist humidifiers are described. In some embodiments, the technologies include a sanitization gas system and a connector unit. The connector unit is configured to install into an opening in the mist humidifier that is used in operation to release mist for humidification purposes. The connector unit includes an inlet passageway for supplying sanitizing gas (e.g., ozone) into the humidifier, and an exhaust system for removing sanitizing gas from the reservoir.
