A PROTECTIVE DEVICE AND ITS ENHANCED VERSION CONTAINING PROPERLY SHIELDED UV SOURCE AND SPECIAL FILTERS FOR CLEARING AIR FROM MICROORGANISMS AND GASES HARMFUL FOR LIFE.

摘要

The invention comprises of new kind of device to provide clean and fresh air from a new kind of mask called UV mask for individual citizens, doctors, and other hospital staff, to protect from air borne pandemic and other air borne diseases by passing of the air through radiation of sufficient intensity and suitable frequency emitted by LEDs fixed on a panel enclosed in a housing which is properly shielded to prevent UV radiation to flow out and do any harm to the user in the path of air to be inhaled and exhaled using this mask so that these rays will do the desirable germicidal action on the microorganisms in the air passing over them and will not do undesirable action of impinging on the body parts of the individuals and other individuals in the surrounding. This housing will act as a protective shield to protect the individuals using this mask and the individuals in the surrounding from the undesirable radiation from the panel of light emitting diodes (or other devices which are suitably powered and emitting suitable frequencies with suitable intensities) emitting sufficiently intense light of suitable frequencies. Essentially we propose that the UV LEDs and similar other devices, should be emitting various different frequencies in the combination and proportion found useful and suitable to disintegrate the infection in the air, are to be used to build the panel. UV mask further employs suitable special filters to ensure safety from hazardous gases that may be present in the air. The enhanced version of this UV mask called UV cover to be fixed at the inlet of air in front of blower blowing the air inside the closed or semi-closed area to supply fresh air for the group of people assembled together is similar kind of device to be used for ensuring clean (free from infections) and fresh (free from hazardous gas pollutions) air for large assembly of people gathered together.
