Patent attributes
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.
