FIELD: medicine.
SUBSTANCE: invention relates to medical equipment. Device comprises two flexible shells, hermetically connected to the ends of the flanges with attached handles mounted to deform the flexible shells, and a respiratory chamber connected through a flexible duct with a facial mask of the injured person. Flexible shells are made in the form of coaxially located and oriented with large bases in different directions truncated cones and have equal volumes, determined by the length of flexible connections between the flanges. Inner surfaces of the flexible shells are fixed by rings of different diameters in such a way that when the height of the truncated cones decreases, during deformation of the flexible shells, the rings enter into each other to form a plane. Breathing chamber through the valves is connected to the internal volumes of flexible shells which are connected to the atmosphere through the valves with the possibility of air input from the atmosphere into one of the shells and air output into the atmosphere from the other, and connected to a manometer to match the operation of the device with the frequency of the patient's own breathing while resuming their own breathing.
EFFECT: technical result consists in reducing the sizes and the cost price.
