Devices for facilitating breathing and methods of using and constructing the same. In at least one embodiment of a device for facilitating breathing of the present disclosure, the device comprises a generally cylindrical central portion configured to surround a head of a user, a top portion coupled to a relative upper end of the central portion, a bottom portion coupled to a relative lower end of the central portion, and an access mechanism coupled to or formed as part of the central portion, the access mechanism configured to open to provide access to the head or a face of the user when the user is wearing the device.

A portable power source couplable to a life safety equipment. A magnetic resonance coupling source is included, the magnetic resonance coupling source is in electrical communication with the portable power source. The magnetic resonance coupling source is configured to wirelessly transmit power to at least one magnetic resonance coupling receiver included in a portable device when the at least one magnetic resonance coupling receiver is positioned within a maximum predetermined distance from the magnetic resonance coupling source.

A rebreather apparatus includes at least one pressurized container of oxygen, at least one pressurized container of a diluting gas, and at least one valve to supply the oxygen and diluting gas to a rebreathing loop. The valve is controlled by a signal from at least one oxygen sensor, wherein the oxygen and diluting gas combine to form a breathing gas that is circulated by the rebreathing loop. At least one container of calibrating gas stores the calibrating gas at ambient pressure and temperature. At least one valve is connected to the at least one oxygen sensor presenting the calibrating gas to the oxygen sensor during calibration of the oxygen sensor and presenting the breathing gas to the oxygen sensor at all other times.

An air purification and disinfection system includes an apparatus having a housing, an ultraviolet disinfection chamber, an air mover, and an air distribution unit in communication with the disinfection chamber. Air is passed through the disinfection chamber where it is purified and disinfected before it is delivered to the user of the apparatus through the air distribution unit. The apparatus can be configured as an open or a closed circuit system. The system may be configured to purify air in an airplane, a conference room, a classroom, or as a portable unit for an individual user. As a portable unit the disinfection chamber can be incorporated into a back pack, a vest, a purse, a briefcase, a shoulder bag, a cervical collar, or any other format for being carried by the user.

A personal protective device (PPE) including a face cover assembly and a bodysuit configured to be worn by a human user. The device protects users against airborne aerosol particles containing viruses or other infectious agents while enabling improved flexibility relative to prior art designs. The device includes a helmet-like” rotating face cover assembly that fits over the user's head and attaches to a collar on the biohazard bodysuit. This rotating face cover assembly has a plurality of different mask sides, each with differing geometries or other properties. The device enables a user to can rotate the cover and select a given mask side that best meets that user's needs. The different mask sides can accommodate different facial geometries, eyewear types, and use cases.

The invention relates to a modular, portable, air purifier device capable of supplying filtered or otherwise conditioned airflow to an individual. More specifically, the present invention provides an air purification system that allows for the remote detection and analysis of local ambient air quality and transmit that information to wirelessly connected devices.

A high-pressure passthrough apparatus and protective suit having a high-pressure passthrough is provided. A high-pressure passthrough having a penetrator body is connected to a protective suit, wherein a first half of the penetrator body is positioned exterior of the protective suit and a second half of the penetrator body is positioned interior of the suit. A high-pressure passthrough valve is positioned on the second half of the penetrator body, wherein high-pressured air is supplied to an interior space of the protective suit. Releasing the quantity of high-pressure air to the interior of the protective suit with the high-pressure passthrough valve may act to cool the interior of the protective suit.
