      Oxygenation Hollow Fiber Membrane
      Hollow-Fiber-Membrane.jpg
      Membrane oxygenator is one kind of micropore hollow fiber oxygenator, which is applied for extracorporeal circulation in extra-cardiac surgery or therapy to oxygenate the blood and remove carbon dioxide. Membrane oxygenator is a medical device to replace the lung in cardiac arrest. It is also a medical device for treating acute respiratory diseases and waiting for lung transplantation.

      Cobetter has developed hollow fiber membrane that is also called gas exchange membrane, which is an very important raw material in membrane oxygenator. The gas exchange capillary works as the medium of gas and blood exchange. The gas and blood on both sides of the capillary can reach the oxygen and carbon dioxide exchange by diffusion.

      Polymethylpentene Gas Diffusion Capillary Structure And Characteristics
      The hollow fiber membrane manufacturered with TIPS technology from Cobetter is with asymmetric structure.
                                                      
      Inner Surface
      Asymmetric ultrathin cortical structure, larger pore size, excellent gas permeability.




      Outer Surface
      Dense cortical structure: small pore size, excellent ability of preventing blood transmission , avoid blood infiltration and blockage, improve the effective lifetime.
