Membrane oxygenator and manufacturing method

The embodiment of the invention discloses a membrane-type oxygenator and a manufacturing method. The membrane-type oxygenator comprises a shell, a membrane-type oxygenator body and a membrane-type oxygenator body, the oxygenation chamber is arranged in the shell, and air channels are formed in the two sides of the oxygenation chamber; the oxygenating element is positioned in the oxygenating chamber, and two ends of the oxygenating element are provided with glue sealing sections; and the two liquid passing pipes are located between the glue sealing sections, and the side walls of the liquid passing pipes are provided with liquid flow channels communicated with the oxygenation chamber. According to the technical scheme, a uniform blood flow path penetrating through the outer surface of the hollow fiber tube in the oxygenation chamber is realized through the liquid flow channel, and compared with a design mode of a blood inlet and a blood outlet generally adopted by a flat oxygenator, the problem that a flowing
