Anti-microbial, disinfection chamber respiratory face mask/shield
View Patent ↗A self-sterilizing, face mask, respirator, open or enclosed face shield employs germicidal, far UV-C light safe for direct human exposure, mitigating risk of acquisition or transmission of respiratory pathogens, such as COVID 19. Device attachments or special lenses direct far UV-C light into the respiratory chamber and/or reservoir areas of infection including nasal, oropharyngeal or ocular areas to reduce or eliminate pathogens, serving also as a treatment modality. In a preferred embodiment the face shield has a removable front section, which can be exchanged or replaced with sections that include various functional attributes while maintaining germicidal protections and avoiding need to remove PPE during these activities including consumption of liquids, oral medications or food, as well as providing antimicrobial absorbent sneeze or cough guard or rhinorrhea secretion absorption, or a communication device to address communication deficiencies caused by respiratory protection barriers.
1. A face mask, respirator, or face shield device providing a respiratory chamber having an interior surface and an exterior surface; and
one or more or an array of built in or attachable or detachable light sources manufactured or attenuated to emit only germicidal far UV-C wavelengths of between 207-222 nm, configured to direct safe, topical application of far UV-C light of wavelength of between 207-222 nm and, directly into the interior of the face mask, respirator, or face shield device to illuminate the interior of the face mask, respirator, or face shield and to directly illuminate skin of a wearer of the face mask, respirator, or face shield and optionally an exterior surface of said face mask, respirator, or face shield devices for air and surface sterilization of respiratory pathogens.
2. The face mask, respirator, or face shield device of claim 1 , wherein the one or more light sources, are attachable/detachable to the face mask, respirator, or face shield device, and/or comprise a u-shaped or other shaped or malleable ring with far UV-C lighted wands or a stylus configured to direct far UV-C light of wavelength of between 207-222 nm to within the interior of the face mask, respirator, or face shield device, or are attachable to at least one nare of the wearer to provide anti-microbial and germicidal sterilization of the respiratory chamber or inhaled/exhaled air or for direct irradiation of nasal or oropharyngeal pathogen reservoirs of the wearer to reduce viral or other pathogen burden combating acquisition or transmission of respiratory pathogens or to treat infection of the wearer by viruses or pathogens.
3. The face mask, respirator, or face shield device of claim 1 , wherein the face mask, respirator, or face shield device is re-useable device.
4. The face mask, respirator, or face shield device of claim 1 , further comprises an attachable face air filtration barrier, cloth or paper, or is an N95 or higher respirator or surgical mask.
5. The face mask, respirator, or face shield device of claim 1 , wherein the face mask, respirator, or face shield device is a face shield or respirator having padding or a skirt formed of malleable material disposed around an internal periphery of the face shield or respirator, to create an enclosed respiratory chamber occlusive to the wearer's skin.
6. The face mask, respirator, or face shield device of claim 1 , wherein the face mask, respirator, or face shield device is a respirator which includes a check valve.
