Disinfection devices are provided which include an enclosure comprising an interior cavity, a closable loading port for providing access to the interior cavity, a cold plasma generator, a fan, a nebulizer and optionally a heating element to heat the interior cavity. In some cases, the cold plasma generator, the fan, and the nebulizer are arranged in the disinfection device such that plasma species generated by the cold plasma generator are routed to an area to which droplets formed by the nebulizer are discharged and the interior cavity is exposed to a mixture of the droplets and the plasma species. In some additional or alternative cases, the disinfection device includes an electronic control system comprising a processor and a storage medium comprising program instructions executable by the processor for terminating operation of the cold plasma generator after a set time period subsequent to terminating operation of the nebulizer.

A shopping cart washing assembly includes a tunnel that is positionable in a location which employs shopping carts wherein the tunnel is configured to have the shopping carts moved through the tunnel. A plurality of lower spray nozzles and a plurality of upper spray nozzles is each integrated into the tunnel to spray a liquid for washing shopping carts. A first drive unit and a second drive unit is each movably integrated into the tunnel. A plurality of grappling units each extends between the first drive unit and the second drive unit. Each of the grapping units engages a handle of a respective shopping cart to transport the respective shopping cart through the tunnel.

A dry mist generating apparatus has a plastic housing, an ultrasonic transducer, a fan inducing airflow within the plastic housing, a diffuser plate for directing airflow, increasing velocity, and decreasing pressure, at least one opening for releasing the resulting dry mist, and a reservoir for capturing droplets that exceed 4 microns.

A disinfection compartment comprising a plurality of wheels; a casing disposed on the disinfection compartment, at least one tank configured to hold antimicrobial solution or hydrogen peroxide solution, a nozzle/dispenser disposed on the casing, and an attachment member configured to provide a detachably secure attachment to a moving unit, wherein the nozzle/dispenser is an electrostatic sprayer or electrostatic gun.

A sanitary washing device includes a nozzle, a casing, an illuminator, and a controller. The nozzle discharges water toward a private part of a user in a state of the nozzle is advanced into a toilet. The casing includes a nozzle storage part configured to store an entirety of the nozzle in a state of the nozzle is retracted. The illuminator irradiates sterilizing light into the nozzle storage part. The sterilizing light has a sterilizing action. The controller controls the illuminator. The controller includes a first irradiation mode of causing sterilizing light irradiated from the illuminator to be irradiated toward an outer circumferential surface of the nozzle. The controller includes a second irradiation mode of causing sterilizing light irradiated from the same illuminator as the first irradiation mode to be irradiated toward an inner wall of the nozzle storage part.

The present disclosure describes a system for sanitizing footwear having a pan, two or more mats positioned in the pan, and a spraying system to spray disinfectant directly on one of the mats. One of the mats is an absorbent mat, which may be a reusable mat, a disposable pad, or a plurality of disposable pads. The other mat is a heavy mat and has one or more cutouts. The heavy mat is positioned on top of the absorbent mat. The system for sanitizing footwear is a quick and easy way to sanitize the soles of footwear in an environment that cannot have moisture or the tracking of water.

Proposed is a non-contact safety relaying apparatus for transferring an object, the apparatus including: an apparatus body including, a main body formed to have an internal space through which first and second independent spaces communicate, a horizontal partition extending horizontally at a height of a center of the main body, with at least one relaying hole being pierced therethrough, an upper partition extending upward from a first side of the horizontal partition and forming a first relaying space, a lower partition extending downward from a second side thereof and forming a second relaying space, a first door mounted on the main body in such a manner as to open and close the first relaying space, and a second door mounted on the main body in such a manner as to open and close the second relaying space; and an opening and closing unit opening and closing the relaying hole.

A method and apparatus for sterilizing medical instruments, including a device for controlling specific humidity, SH, of flow of a gas or gas mixture. The device includes a tank for storing a volume of water. The tank has an inflow port for receiving the gas or gas mixture, and an outflow port for allowing humidified gas or gas mixture at the required SH to exit the tank. The temperature of the water and/or the pressure of the supplied gas or gas mixture are controlled for the required SH.

The invention relates to an apparatus for vapour decontamination of an enclosed space. The apparatus comprises: (a) a reservoir comprising a supply of a liquid decontaminant; and (b) a vaporiser unit in fluid communication with the reservoir. The vaporiser unit comprises: a body that defines a lumen that passes along the length of the body, the lumen comprising a first end and a second end, wherein the first end receives liquid decontaminant from the reservoir; and a heating element that is configured to deliver sufficient thermal energy to effect rapid boiling of the liquid decontaminant within the lumen so that it exits the lumen via an exit port at the second end of the lumen as a vapour. The exit port is configured to deliver the vapour into a flow of a non-heated carrier gas, thereby facilitating distribution of the decontaminant vapour within the enclosed space. The invention also relates to a method for decontaminating surfaces within an enclosed space.
