The invention relates to a protective device such as a face mask. The device protects the user from infection and may simultaneously immunise the user against future infection. The invention particularly relates to a protective device comprising a disinfection chamber wherein the chamber is arranged to disinfect and/or sterilize fluid in the chamber prior to discharge of the fluid from the chamber such that the fluid discharged from the chamber comprises inactive microorganisms, for example a device comprising a disinfection chamber in fluid communication with a face mask and wherein the chamber is arranged to disinfect and/or sterilize fluid in the chamber prior to discharge of the fluid from the chamber to the mask such that the fluid discharged from the chamber to the mask comprises inactive microorganisms. The invention also relates to a method of use of the device.

The invention provides a device used for blocking infecting of diseases such as novel coronavirus spread by droplets. The device comprises a chemical sterilization and disinfection unit, a physical sterilization and disinfection device, an air filter, a hood and other auxiliary unit. Different combinations of the units of the device can achieve two work states, the positive-pressure work state andthe negative-pressure work state. When the device is in the positive-pressure work state, the hood is full of sterilized and disinfected air, the pressure is higher than environment pressure, and thedevice is suitable for healthy personnel working in environments where people are likely to be infected. When the device is in the negative-pressure state, the internal pressure of the hood is lowerthan the environment pressure, air exhaled by users is exhausted into the environment after being sterilized and disinfected, and the device is suitable for being used by suspected infected patients or diagnosed infectious victims. According to the device capable of reducing the concentrations of bacterial viruses in the local environment through direct sterilization and disinfection, bacterial viruses are eliminated from the source and are killed before being diffused, healthy personnel who have to work in the environment are protected, and the patient recovery process is promoted.

The invention discloses a fresh air healthy atmosphere coronavirus prevention and control mask. The mask is composed of a positive pressure type air input device, a nanofiber filtering device, a maskbody and an air disinfection device, wherein the mask body is composed of a mask frame, a transparent face window, an air inlet channel, an air outlet channel, a sealing rubber strip and a wearing elastic band; the mask frame is in an oval shape similar to the face shape of the human body; the transparent face window is in an outward convex shape; the outward convex size can envelope the face organ; the transparent face window is mounted in front of the mask frame; the sealing rubber strip is mounted behind the mask frame; and the transparent face window and the mask frame form a closed cavitywith the human face through the sealing rubber strip. The fresh air healthy atmosphere coronavirus prevention and control mask can comprehensively protect the mouth, nose and eyes of the face of thehuman body, filtered positive pressure type air is input through the air inlet channel to ensure inhaled air needed by the human body, the exhaled air is discharged through an exhalation channel and enters the disinfection device to kill harmful viruses and then is discharged into the air, and cross infection to surrounding people can be eliminated.
