Abstract

The invention discloses an oxygenator. The oxygenator comprises a shell, an oxygenation layer, a temperature layer, gas openings, fluid openings and a blood opening; the shell comprises an outer shell and an end cover; the blood opening and an exhaust hole are formed in the end cover; the oxygenation layer is formed by stacking a plurality of oxygenation films and forms a gas passage with the gas openings; the temperature layer is formed by stacking a plurality of temperature films, and forms a fluid passage with the fluid openings; and the blood opening and the gap between the oxygenation layer and the temperature layer form a blood passage, and the structure is used for conducting gas exchange and temperature control on blood. The invention discloses the oxygenator which is optimized in structure, excellent in performance and capable of solving the problems of rupture, liquid leakage, poor oxygenation efficiency, thrombosis and the like in the clinical use process.

Description

technical field [0001] The invention relates to a medical device, in particular to an oxygenator. Background technique [0002] When a patient suffers from cardiogenic shock, severe respiratory failure, or cardiac arrest during surgery, an extracorporeal circulation support system is often used to maintain the patient's life. In the process of extracorporeal circulation, the blood is drawn out from the human vein, and after being oxygenated and heat-exchanged by the oxygenator, it is reinfused into the human body. The oxygenator replaces the lungs to support the breathing and circulation. [0003] At present, the common oxygenator is membrane oxygenator. This kind of oxygenator uses the difference in gas concentration inside and outside the hollow fiber to exchange oxygen and carbon dioxide. The blood does not directly contact with the gas, which is different from the traditional bubble oxygenator. Compared with greatly reducing the risk of air embolism and hemolysis. Howe...
