A system for thermal regulation of a nebulizer is provided that is structured to deliver a chilled mist to the snout, muzzle, beak, or trunk of an animal. The system includes a container to house a nebulizer and a thermal material together and a mask to deliver the chilled mist to an animal. The thermal material acts to chill a liquid located inside the nebulizer in order to deliver a chilled mist to the animal for therapeutic purposes, such as initiating therapeutic hypothermia, or treating various respiratory illnesses such as croup, laryngobronchitis, and smoke inhalation.

There is provided an apparatus for preparing a ventilation gas mixture that comprises a gas mixing device, a first gas feed arranged to supply a first gas to the gas mixing device, an air inlet configured to receive exhaled air from a person, a gas reservoir arranged to store carbon dioxide from the air received in the air inlet and further arranged to supply the stored carbon dioxide to the gas mixing device via a second gas feed, wherein the gas mixing device is arranged to combine the first gas with the carbon dioxide in order to prepare the ventilation gas mixture.

Disclosed example respirators comprise: a filter configured to filter the air; a blower fan configured to provide continuous air flow at variable speeds; an air duct configured to direct air from the blower fan to an exhaust location, the blower fan configured to blow air through the air duct; and a blower controller configured to: control the blower fan to automatically adjust an airflow speed of the blower fan to a plurality of airflow speeds over a plurality of different time periods, the plurality of airflow speeds being within an airflow speed range.

A portable air treatment system configured to be carried by an individual and deliver air, via a mask, to the individual, is provided. The system includes an air inlet allowing atmospheric air to enter at an air flow rate ranging between 2 liters/min to 10 liters/min, an air compression system connected with the air inlet for compressing the incoming air, thereby increasing the temperature of the air to a minimum temperature of 170 C., a hot air chamber connected with the air compression system for receiving the heated air from the air compression system and retaining the heated air for a period of 30-100 milliseconds, an air decompression system connected with the heated air chamber for expanding the heated air thereby decreasing the temperature of the heated air to a temperature ranging between 14 C. to 45 C., and an air outlet connected with the air expansion system for directing the cooled air to the individual via the mask.

An air breathing device includes a casing and an air passage cavity encompassed by the casing. The device includes an air intake port and an air discharge port that connect the air passage cavity to the outside of the casing. The device includes a damper (gravity or motorized) that allows the air to flow into the air passage cavity during inhalation through the air intake port. The device includes a damper (gravity or motorized) that allows the air to exit the air passage cavity during exhalation through the air discharge port. The device includes a retractable display screen to display content to the wearer. The device includes a fixed display screen to display images of the mouth of the wearer captured by a camera lens or simulated based on the wearer's captured voice. The device includes UV lights, filters, network connections, camera lenses, speakers, microphones, ear plugs, and heating coils.

The present disclosure provides an oxygen breathing apparatus. The present disclosure provides an oxygen breathing apparatus including a hose including one end portion, another end portion opposite the one end portion, and a connector provided between the one end portion and the other end portion and configured to allow a mouthpiece to be mounted thereon; a fan connected to the one end portion of the hose; an exhalation bag connected at one side to the fan, and fluidly connected at another side to the other end portion of the hose; an oxygen supply device configured to store oxygen, and connected to the exhalation bag; and a controller configured to control driving of the fan so that the fan forms a unidirectional air flow within the hose.

Invention is described which sterilizes air contaminated with airborne virus by means of superheating the air to over 400 Fahrenheit then cooling air to breathable temperatures. The invention disposes a fan pushing contaminated air into a positive temperature coefficient semiconductor heater to superheat the air which is subsequently cooled by a two stage cooling system. First stage of the cooling system is an air-to-air heat exchanger using ambient air from second fan to cool the superheated air. The second stage of cooling is provided by a solid-state Peltier heat pump which further transfers heat energy to ambient air provided by a third fan. Invention is disposed onto a sealed helmet which the sterilized air is conveyed causing an overpressure to eliminate the possibility of contaminated air entering the helmet. The invention is entirely reusable after use in a contaminated environment and does not rely on filters to remove airborne virus.

There is provided a humidifier for a respiratory therapy system that includes a humidification chamber having an inner wall spaced from an outer wall to form a wall cavity between the inner and outer walls. A gas flow path is located within the wall cavity. Gas, such as air, flows along the gas flow path from an inlet to the humidification chamber to an outlet of the humidification chamber. Optionally, the gas flow path may follow a helical route through the wall cavity.

Apparatuses and methods reducing humidity in respiratory protective devices are provided. For example, an example respiratory protective device includes a humidity sensor component embedded in an exhalation filtration component of the respiratory protective device, at least one fan component positioned adjacent to an inhalation filtration component of the respiratory protective device, and a controller component in electronic communication with the humidity sensor component and the at least one fan component.
