The invention discloses a partial liquid ventilation intelligent auxiliary device. The partial liquid ventilation intelligent auxiliary device comprises a breathing machine, a PFC liquid pool, an oxygenator, a throttling valve, a first driving pump, a second driving pump and a gas-liquid separation tank; the breathing machine is provided with an inspiration pipeline and an expiration pipeline; a liquid outlet of the PFC liquid pool is connected with the input end of the oxygenator through the first driving pump; the output end of the oxygenator is connected with the input end of the throttling valve; the output end of the throttle valve is connected to the inspiration pipeline; the gas-liquid separation tank is connected to the expiration pipeline; and a liquid outlet of the gas-liquid separation tank is connected to a liquid inlet of the PFC liquid pool through the second driving pump. A partial liquid ventilation mode is adopted, complete synchronous lung ventilation is carried out by connecting the breathing machine, PFC equivalent to functional residual gas is injected into a lung so as to eliminate a gas-liquid interface in pulmonary alveoli, gas exchange of ARDS can be effectively improved, lung compliance is improved, lung injury and inflammatory response caused by the breathing machine are relieved, and the overall curative effect is obviously better than that of conventional mechanical ventilation and complete liquid ventilation.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to an intelligent auxiliary device for partial liquid ventilation. Background technique [0002] Acute respiratory distress syndrome (ARDS) is the injury of non-alveolar epithelial cells and capillary endothelial cells caused by various direct and indirect injury factors, resulting in diffuse pulmonary interstitial and alveolar edema, resulting in acute hypoxia Sexual respiratory insufficiency. The pathophysiological features are reduced lung volume, decreased lung compliance, and imbalance of ventilation / perfusion flow ratio, clinically manifested as progressive hypoxemia and respiratory distress, and lung imaging manifested as heterogeneous exudative lesions . ARDS is a multi-etiological clinical syndrome characterized by refractory hypoxemia, persistent pulmonary inflammation, and increased vascular permeability. The etiology of ARDS can be classified as primary lung i...
