APPARATUS FOR CARRYING OUT ARTIFICIAL LUNG VENTILATION

FIELD: medical engineering. ^ SUBSTANCE: device has respiration unit, unit for controlling and unit for supplying inhalation mixture. The respiration unit has dividing bellows coupled with bellows of lesser effective area. The bellows are fixed between movable and unmovable covers. End switches are mounted near the cover projection. The respiration unit has two pneumatic switches, electric switch and membrane valve. Cover movement is initiated by mechanism as a result of engine rotor rotation controlled by controller signals. Reverse valve is mounted on inhalation line and membrane valve is mounted on exhalation line so that pneumatic signal of pneumatic pulse generator into the valve through the switch. The inhalation and exhalation lines, are connected to patient T-switch with flexible hoses. The control unit has membrane valve, electric engine, pneumatic pulse generator, pressure converter and controller. The unit for supplying inhalation mixture has element for dosing gas mixture, valve for atmospheric air inflow valve, respirator receiver sack and safety valve. Gas from the receiver sack enters the bellows via the valve. Electric power of the control unit is maintained with pulsating power supply source. ^ EFFECT: high accuracy in dosing respiratory volume from 20 to 2000 ml; wide range of functional applications. ^ 2 dwg
