FIELD: medical equipment, in particular, pulmonary artificial ventilation apparatus used in medicine of disasters, ambulance and emergency medical services. SUBSTANCE: specific conditions of the medicine of disasters, ambulance and emergency services put forward strict demands to the equipment for rendering urgent medical aid to patients at injuries and diseases of various kinds, in particular, mass, dimensions and simplicity in use. The pulmonary artificial ventilation apparatus has a valve for adjustment of lungs ventilation connected to the supply line, the valve outlet through, successively connected outlet member, injector and breather hose is connected to the device used for connection to patient; as well as a toggle switch connected to the respiration rate control throttle valve, first inputs of the balance relay, storage location and an inverter, whose second input is connected to the output of the storage location, whose switching input is connected to the output of the first balance relay connected via the second input to the first output of the first air relay. The apparatus has a second balance relay and second air relay connected via the inputs the inverter output, first and second outputs of the first air relay; the second output of the first air relay is also connected to the vessel and second balance relay, whose output is coupled to the switching input of the storage location; the outputs of the second air relay communicate with the atmosphere. EFFECT: enhanced reliability. |
