6980 cases of China Eco-Membrane are used every year. With the improvement of domestic medical level and the in-depth study of extracorporeal membrane oxygenation, the domestic demand for extracorporeal membrane oxygenation continues to rise. In 2020, affected by the epidemic situation in COVID-19, the number of applicants for extracorporeal membrane oxygenation reached about 6,980, mainly in Henan and Guangdong. From the application demand, extracorporeal membrane oxygenation in China is mainly used for adults, mainly for the situation of impaired cardiac function. The upstream of extracorporeal membrane oxygenation is mainly composed of artificial heart, artificial lung, lung membrane and other important disposable medical consumables. There are three main materials for lung membrane, namely solid silica gel membrane, microporous hollow fiber membrane and solid hollow fiber membrane, among which the first two have some defects in clinical application, while solid hollow fiber membrane combines the advantages of the above materials and has the advantages of long service life and difficult bleeding. At present, only one company in the world can produce it, so the price remains high.
