FIELD: medicine.

SUBSTANCE: protective mask with a mouthpiece belongs to the field of medicine, namely to the means of individual protection of the upper respiratory tract, and can be used to protect the population from bacterial and viral infections, harmful components of gas and smoke. The protective mask with a mouthpiece includes a half mask with a mount. In the central part, an inhalation valve is installed on the surface of the half-mask between the user's nose and mouth. In the under-mask space at the level of the user's mouth, the half-mask contains a mouthpiece. The mouthpiece is an elastic dental cap for the upper and lower rows of teeth with a through hole located in the central part between the pads for the upper and lower rows of teeth, which is connected to a channel that follows the shape of the hole, and has a plate curved in a semicircle at the exit hole from the channel. The mouthpiece is paired with a "T-shaped" tube. The outlet openings of the "T-shaped" tube are connected to the exhalation valve. The exhalation valve is located on the surface of the half mask.

EFFECT: creation of a protective mask, the design of which eliminates the mixing of exhaled and inhaled air in the undermask space due to the fact that the half mask in the undermask space at the level of the user's mouth has a mouthpiece connected to a "T-shaped" tube at the outlet openings of which an exhalation valve is installed, thereby allowing the exhaled air to be discharged directly into the atmosphere without entering the undermask space.
