ARTIFICIAL PULMONARY VENTILATION APPARATUS Russian patent published in 2000 - IPC

FIELD: medical engineering; applicable under conditions of first aid, extremal medicine, in anesthesiology, reanimatology and intensive therapy, and in replacement of temporarily lost ventilation function of organism. SUBSTANCE: apparatus has control pulse generator with regulator of ventilation frequency, regulator of minute pulmonary ventilation, regimes switch, gas flow distributor, manual control member of artificial pulmonary ventilation, patient valve, patient line, valve of additional inhalation, safety valve, concentration setter, pressure stabilizer, pressure gage, inhalation unit. Apparatus under conditions of controlled artificial pulmonary ventilation, manual artificial pulmonary ventilation and inhalation forms oxygen-air mixture with preset concentration of oxygen and maintains its value continuously within preset range of regulation of minute ventilation, and maintains invariably preset frequency of inhalation. Breathing bag is prevented from abnormal inflation and pressure in patient respiratory tracts is controlled over. EFFECT: extended functional potentialities of apparatus. 6 dwg
