FIELD: medical engineering. SUBSTANCE: device has compressor unit, exudate collector unit, draining units. Unit for automatically expanding lung is introduced as two-chamber pneumatic system with feedback. It has two chambers, feedback canal, flexible membrane and two valves mechanically coupled to each other. The pleural cavity is accessed through exudate collector unit and draining units. The outlet is connected to the compressor unit. The valve is opened by means of the flexible membrane and closed under vacuum influence. EFFECT: enhanced effectiveness of treatment; automatically supported pleural cavity rarefaction. 1 dwg
