ARTIFICIAL PULMONARY VENTILATION DEVICE Russian patent published in 2015 - IPC A61H31/02 

FIELD: medicine.

SUBSTANCE: artificial ventilation device contains an inhalation gas generator connected to the flow rate regulator with means for communication with the patient via the rotameter by a low pressure line and an electromagnet valve controlling gas mixture flow direction into the atmosphere or into the patient's lungs. The valve is installed on the exhalation hose and connected to the square-pulse generator and to the computer with the help of corresponding cables. The electronic regulator is represented by a square-pulse generator. The pulses frequency corresponds to that of breathing cycles; pulse relative duration corresponds to that of inhalation and exhalation. The device is equipped with software with a data base and a controller blocking the valve actuating.

EFFECT: design improvement.
