Systems and methods for cleaning and maintaining artificial airways sized for insertion within pediatric or neonatal patients (e.g., external diameters of less than 5 mm) are disclosed. The system includes a multi-port ventilator manifold configured to couple to a ventilation source, thereby forming a ventilator circuit with the patient. The manifold includes an occluder configured to advantageously reduce an amount of dead space in the manifold so as to prevent loss of positive end expiratory pressure of the ventilator circuit and reduce the likelihood of broncho-pulmonary dysplasia of the patient, or even premature death.

Provided is a compact ultraviolet irradiation device in which a degree of an adverse effect on the human body is suppressed. The ultraviolet irradiation device includes: a lamp house on the surface of which a light extraction surface is formed; an excimer lamp accommodated in the lamp house, a main emission wavelength of which belongs to a first wavelength band of 190-225 nm; an optical filter that is arranged on the light extraction surface and substantially transmits the ultraviolet light in the first wavelength band and substantially reflect the ultraviolet light of a wavelength of 240-300 nm; and a reflecting surface that is a surface located outside the luminous tube of the excimer lamp and inclined with respect to the light extraction surface, the reflecting surface exhibiting reflectivity with respect to the ultraviolet light in the first wavelength band.

A device for disinfecting surfaces is provided. One embodiment has a plurality of UV light (energy) emitting LEDs residing in an enclosure, wherein emitted UV energy passes through a lens onto a surface being disinfected; a heat dissipator that receives heat generated by the UV emitting LEDs; and a fluid moving device. The enclosure has a fluid heating passageway that is in fluid contact with the heat dissipator, has a transfer passageway with a distal end that is fluidly coupled to a proximal end of the fluid heating passageway, and has a return passageway that is fluidly coupled to a proximal end of the transfer passageway and that is fluidly coupled to a distal end of the fluid heating passageway. During operation, the fluid moving device operates to circulate a cooling fluid through the fluid heating passageway, the transfer passageway, and the return passageway. Heat transfers to the ambient environment.

A UV sanitizing device including a sanitizing interface having a top surface arranged to support a device positioned above the sanitizing interface where the sanitizing interface includes a translucent material arranged to allow UV light to pass through An adjustable UV emission interface, positioned adjacent to the sanitizing interface, arranged to adjustably conform to the shape of a device facing the sanitizing interface, and arranged to emit the UV light toward the sanitizing interface in the shape of the device. The adjustable UV emission interface includes UV emission interface cells such that, when a first portion of the UV emission interface cells is activated and a second portion of the UV emission interface cells is deactivated, the UV emission interface conforms to the shape of the device. Each cell of UV emission interface cells includes a sensor arranged to detect a portion of the device facing the sanitizing interface.

There is provided a system and method of cleaning surfaces of an enclosable environment of a contamination comprising a microbial and viral load. The method includes the steps of sealing the enclosable environment and placing water, and a solid or gel pack, into a container and generating a vortex the container by rotating an impeller. The agitation causes the solid or gel pack to release a gaseous cleaning agent. An air-borne spray exiting from the container spreads throughout the enclosable environment to contact the surfaces to be cleaned within the enclosable environment. The enclosable environment is maintained closed for an effective time period while the air-borne spray dwells on the surfaces to eliminate or substantially reduce the load of the contamination.

The invention relates to a disinfection system for a motorized vehicle comprising at least one disinfectant light emitting device mounted in a vehicle cabin and arranged to emit disinfectant light rays towards internal surfaces of the vehicle cabin so as to sanitize them, first sensor means adapted to sense the presence of a human or an animal inside the vehicle cabin and providing a first sensing signal indicating no presence, and a controller operatively connected to the at least one disinfectant light emitting device and the first sensor means, the controller receiving the first sensing signal, wherein the controller is adapted to operate the at least one disinfectant light emitting device in response to the first sensing signal.

A modular disinfection vehicle. The disinfection component is designed into an independent extensible structure, where there is a light source module between the upper end and the lower end of the disinfection component, the upper end of the disinfection component is the first fixing part, the lower end of the disinfection component is the second fixing part, the upper end of the disinfection component is of a dismountable structure, so that the light source module can be replaced and maintained conveniently; when the quantity of the light source modules needs to be increased or decreased, only components and parts at the upper end or/and the lower end of the disinfection component need to be replaced, there is no need to significantly improve the overall structure of the disinfection vehicle, so that the quantity of light source modules of the disinfection vehicle can be increased or decreased conveniently.

A system for activating an emitting module is provided. A computer device identifies (i) environment data relating to an environment, and (ii) user data relating to a user located within the environment, wherein the user is wearing a wearable computing device. The computing device predicts that the user will interact with a surface in the environment based, at least in part, on the environment data and the user data. The computing device selects at least one emitting module from a plurality of emitting modules on the wearable device based, at least in part, on a predicted proximity of the at least one emitting module to the surface. The computing device prompts the user to activate the at least one emitting module.

An ozone treatment system which is usable in enclosed or confined spaces for the inactivation of pathogens such as bacteria and viruses in these spaces.

The present disclosure relates to an ultraviolet (UV) sterilization device, and more specifically, to a UV sterilization device whose radiation mode and position may be changed. The UV sterilization device includes: a sterilization unit configured to be movable up to a specific position and including a UV emission unit; a driving unit configured to move the sterilization unit; and a lens assembly including at least two different types of lenses and provided on a front surface of the UV emission unit.
