APPARATUS FOR ARTIFICIAL LUNG VENTILATION Russian patent published in 2012 - IPC A61B16/00 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment. Apparatus contains control unit with electric drive and pressure converter, pneumatically connected with patient's T-joint; respiration unit, which includes separating bellows, mechanically connected with electric drive, lines of patient's inhalation and exhalation, connected with patient's T-joint, inhalation line being pneumatically connected with separating bellows, membrane controlled valves, installed on patient's inhalation and exhalation lines; and unit of respiratory mixture supply, which includes gas mixture dosing device, whose inlet is pneumatically connected with source of compressed medical gases, and outlet - with respiratory bag, safety valve and valve of atmospheric air suction, as well as with separating bellows via reverse valves. Pressure source is made in form of diaphragm pump, is installed in control unit and is provided with system of pneumodistributors. Pump outlet is pneumatically connected via first pneumodistributor with controlled valve on patient's inhalation line, and via second and third pneumodistributors - with controlled valve on patient's exhalation line. In control unit installed is gas-jet injector, whose inlet is connected via fourth distributor with source of compressed medical gases, outlet via one of reverse valves - with patient's inhalation line, and line of injector suction is connected with outlet of gas mixture dosing device.

EFFECT: extension of used ventilation modes.
