APPARATUS FOR APPLYING ARTIFICIAL LUNG VENTILATION Russian patent published in 2001 - IPC

FIELD: medical engineering. SUBSTANCE: device has flow generator, patient T-piece, control system, transducers for measuring flow rate and pressure in the upper breathing paths connected in pneumatic way to the patient T-piece and to the control system in electric way. The device has gas distribution unit having inhalation choke regulator unit, exhalation choke regulator unit and proportional electropneumatic regulator unit. The inhalation choke regulator unit is connected to flow generator outlet through a pneumatic inlet and through pneumatic outlet to patient T-piece inhalation line. It is connected to the first electric output of the control system through the electric input. The exhalation choke regulator unit is connected to the patient T-piece inhalation line through pneumatic inlet, to atmosphere through pneumatic outlet. It is connected to the second electric output of the control system through the electric input. The proportional electropneumatic regulator unit is connected to compressed oxygen source through pneumatic inlet. It is connected to the patient T-piece inhalation line through pneumatic outlet. It is connected to the third output of the control system through the electric input. EFFECT: wide range of functional applications; simplified design. 2 dwg
