Appl.No 17698126 Applicant Phillip Reyes Inventor Phillip Reyes

A breathing device related to the field of personal protective equipment and wearable technology that can be cleaned and sterilized so that it can be used repeatedly is disclosed herein. The device is configured to surround the mouth and nose of the user, and in some embodiments, it surrounds the eyes. The perimeter of the device can be comprised of a stretchable material that conforms to the contours of the user's face so that it provides an adequate seal, and in doing so, ensures that all or most of the air flowing through the device occurs through its air filtering regions. The filtering region is configured so that filtering material can be mounted to the device and replaced when needed. This filtering region is also configured so that a negative pressure seal test can be performed. Various embodiments of the device exist that enhance its capabilities from its most basic form. For example, in some embodiments, wearable technology is mounted to the device, is connected to the device, or is embedded within the device. This technology can include, but it not limited to sensors, microprocessors, cables, wires, actuators, soft robotic or soft machine materials, energy supply systems, and smart materials.

Aspects of the present disclosure include a protective mask to be worn over a nose and mouth of a wearer to protect the wearer from hazards in surrounding ambient air. The mask includes a mask portion, an airway, and an ionization filter. The mask portion includes an interior that extends over the nose and mouth of the wearer. The airway extends between the interior of the mask portion and the surrounding ambient air. The ionization filter includes an emitter within a portion of the airway, and a collector plate radially encompassing the emitter and defining at least a portion of the airway. The collector plate is electrically connected to at least first and second conductive porous filters. The first and second conductive porous filters and the collector plate collectively form at least a portion of a Faraday cage that encapsulates the emitter.

A portable two-way protective respirator system to be worn by a person that filters ambient air of harmful viruses, bacteria, and other airborne contaminant particles and vapor components for safe beathing, while also removing any harmful viruses, bacteria, and other airborne contaminant particles and vapor components from the person's exhaled airstream before it is emitted to the surrounding community is provided according to the invention. The system comprises a respirator mask connected by a flexible hose to an air inflow blower fan unit containing filter media that produces an incoming airstream for a first chamber contained inside the respirator mask free of harmful contaminant particles and vapor components. A gaiter extending from the bottom of the respirator mask defines a second chamber for a second airstream exhaled by the person to remove viruses and bacteria from that second airstream as it passes between the threads of the finely woven gaiter.
