AI Technical Summary

Technical Problem

Existing ECMO membrane oxygenators suffer from thrombosis and plasma leakage, making it impossible to guarantee long-term stability and gas exchange efficiency.

Method used

It adopts an ultra-thin, dense, and defect-free hollow fiber composite membrane with a coating material of fluororubber or silicone rubber. Gas exchange is carried out through dissolution-diffusion, which avoids plasma leakage and enhances biocompatibility and hydrophobicity.

Benefits of technology

It achieves efficient gas exchange, reduces blood rejection and platelet adhesion, and ensures long-term stability and service life.
