Abstract

The invention provides an extracorporeal membrane lung oxygenator which comprises a main shell, a first end and a second end cover, the first end and the second end cover are arranged at the two ends of the main shell, the main shell comprises a center cavity for blood to flow in, a temperature control cavity and a gas exchange cavity, and the temperature control cavity and the gas exchange cavity spirally surround the center cavity; an annular space is formed among the temperature control cavity, the gas exchange cavity and the inner wall of the main shell; the first end cover is provided with a blood inflow runner communicated with the central cavity, and a temperature control medium outflow runner and an oxygenation medium outflow runner which spirally surround the blood inflow runner; the second end cover is provided with a blood outflow flow channel communicated with the annular space, and a temperature control medium inflow flow channel and an oxygenation medium inflow flow channel which spirally surround the blood inflow flow channel; the flowing sectional area of the temperature control medium flowing-in flow channel is gradually reduced; and the flowing sectional area of the oxygenation medium flowing-in flow channel is gradually reduced. The pressure of the oxygen-enriched gas and the pressure of the temperature control medium can be evenly distributed, and the optimal heat and gas exchange efficiency is achieved.

Description

technical field [0001] The invention relates to an extracorporeal membrane oxygen supply device for assisting cardiopulmonary function, in particular to an extracorporeal membrane oxygenator. Background technique [0002] Extracorporeal membrane oxygenation (ECMO) is an extracorporeal circulatory system with both heart and lung assist functions. Through the arteriovenous cannula, the blood is drained from the body to the outside. After membrane oxygenation, the oxygenated blood is perfused into the body by the pump to maintain the blood and oxygen supply of various organs of the body. It is performed on patients with severe cardiopulmonary failure. Breathing heart support for a longer period of time allows the patient's heart and lungs to rest adequately and wins precious time for further treatment and recovery of heart and lung functions. [0003] The oxygenation function module and the heat exchange function module of the existing membrane lung oxygenator are mostly indep...
