FIELD: medicine.
SUBSTANCE: invention refers to apparatuses to be used in emergency situations or irrespirable atmosphere operations. A respiratory apparatus comprises a face portion, a regeneration assembly with a starting gear, a filter, a distribution assembly provided by a rotation cam, inspiratory and expiratory valves, a gas passage coupling the regeneration assembly and the distribution assembly. The starting gear is coupled by traction with the distribution assembly. The respiratory apparatus comprises a rotary mechanism that enables filtering to isolating protection mode selection.
EFFECT: construction implementation of the apparatus enables eliminating potential user poisoning by atmospheric harmful substances when using the apparatus.
