Abstract (en)
[origin: EP3632248A1] The claimed group of inventions relates to personal protective equipment, and specifically to masks intended primarily for use in the field of medicine. The technical result of the claimed group of inventions is that of improving working conditions for medical personnel for the entire duration of use of a mask, while providing complete protection against the penetration of infections and any liquid media into the respiratory organs both, for example, from an operation site, and into patients, as well as complete protection of a user against airborne droplet infection in public places. A barrier-discharge-type medical mask with a frame comprises a hollow frame which forms a mask cavity for the lower part of a face and is designed in the form of a channel containing inlets and outlets for the passage of air flows. The outer, transparent side of the frame is airtight, and the side adjacent to the surface of the face is made of an elastic, airtight fabric. The frame contains a shield covering part of the nose, forming a mask cavity for the middle section of the face.
