Alternatively, the UV light chamber and the breathing mask may be in fluid communication via the breathing tube.

An improved safety device for a self-contained breathing apparatus, and an improved self-contained breathing apparatus having thermal imaging capabilities.

An airflow device configured for creating an air barrier includes a fan, a power source, a laminar assembly, and an attachment mechanism. The power source is coupled to the fan. The laminar assembly includes a plurality of tubes and is coupled to the fan so that air flow generated by the fan passes through the plurality of tubes to create the air barrier. The attachment mechanism attaches the laminar assembly to a user in a location near the user's head such that the air barrier created by the laminar assembly is positioned in front of the user's face. A plenum is positioned between the fan and the laminar assembly such that the air flow generated by the fan passes through the plenum and then through the laminar assembly. The airflow device acts as a face shield that protects the user from airborne contaminants and viruses.

A device for individual protection and isolation against pollutants and microorganisms comprises a protection element (1) of the face designed to be worn by the user to at least partially cover the face and a filtering group (2) of the air inhaled and/or exhaled by the user. The protection element (1) is adapted to cover at least the whole face of the user and has at least one mouth for the passage of air provided with a one-way check valve (7) suitable to selectively allow the entry and the exit of air from said protection element (1), said filtering group (2) comprising a filter body (4) housing a filter (15) for purifying the entering or leaving air and in fluidic connection with the inside of said protection element (1) by means of an access made in said protection element (1) distinct from said mouth, said filter body (4) having a first opening for drawing air from the outside and/or the expulsion of air towards the outside and a second opening for the delivery of the air into and/or the withdrawal of air from said protection element (1).

This invention is a smart face mask for air filtration with a transparent mouth-covering portion, an active air filtration system which filters both air inflow and air outflow, an environmental or biometric sensor, and a smart control mechanism wherein the operation of the active air filtration system is automatically adjusted based on analysis of data from the sensor.

Air to be inhaled by a user can be treated to remove contaminants by passing the air through a multistage treatment system. The multistage treatment system can include an inhalation treatment unit for treating air to be inhaled by the user, a mask wearable on the user's face, and an exhalation treatment unit for treating air exhaled by the user. The inhalation treatment unit and the exhalation treatment unit can each include various sub-units and assemblies for removing naturally occurring vapors and pathogens as well as compounds generated by operation of the treatment system.

The present invention corresponds to a full-face respiratory mask that prevents the entry and exit of particles during the breathing process. The mask has a hermetic seal against the skin that does not allow particles found in the environment to pass through and a single opening that is also hermetically sealed, this opening is coupled with the outer filter and is where the filtered air enters and exits.

Protective breathing apparatus incorporates a powered air pump which introduces potentially contaminated air from the atmosphere to the ‘process chamber’. The process chamber are composed of a filter and disinfectant solution such as soap, alcohol by adding the solution mixed with the contaminated air passes through the filter to catch a virus in the inlet air to separate the processed air and solution. Furthermore the processed air can be heated and/or be exposed to UV light, the air is then forced to pass through a disinfectant into a centrifuge. The centrifuge then spins the disinfected air forcing the air through a filter, the air then passes a mechanical filter resulting in purified air that flows through conduit means into a transparent plastic breathing hood containing the wearer's head. The hood is secured by a neck band around the wearer's neck. Newly purified air in the breathing hood is distributed and circulated throughout the hood's interior, the current of air holds the hood out of contact with the wearer's head. After the purified air has been inhaled and exhaled by the wearer, it is expelled through an exhaust port in the breathing hood. The exhaled air has potential to be contaminated. The exhaust air travels through conduit means back to the process chamber, this redirected exhaust air is purified before its release back into the atmosphere so no contaminates are expelled into the atmosphere. Optional provision is made for adjusting the temperature of the newly purified air for optimal user comfort, and for a plurality of breathing hoods to be supplied by a single air purifying device.

The above device can be stationary without the breathing hood. Similar to a dust cleaner, but it can kill the virus.

A respirator system includes a respirator with an air filter, a flow generator with a sensorless DC motor, a mask, a processor, a sensor, an electric power source, and a wireless transceiver. The respirator filters air, increase the pressure of the air, delivers the air to the mask at a pressure above ambient, gathers data with the sensor about operation of the respirator, and transmits the data. An intermediate electronic device is separate and remote from the respirator, and is configured to receive the transmitted data process the data, and re-transmit the data. A computer receives the data, processes the data and generates at least one report regarding the respirator or a user of the respirator.

A face shield system utilizes a headgear with an outer shield and an optional inner side that is proximal to a person wearing the face shield. The headgear may be configured to receive a disinfecting cartridge that neutralize or destroy pathogens in an airflow flowing therethrough. The cartridge may include a neutralizing UV light emitter and a destroying UV light emitter as well as an ionizer. The plenum may include a plurality of baffles to produce a serpentine flow through the plenum. The baffles and the interior of the plenum may be textured and polished and may include catalytic coatings for improving the effectiveness of pathogen destruction and absorbing ions and UV light. An air inlet may allow air from the plenum to pass into the inner side of the shield after the air is disinfected and purified by the UV light emitters.
