Polysulfone-based hollow fiber membrane and hollow fiber membrane module for purifying blood products

摘要

The present invention provides a polysulfone-based hollow fiber membrane and a hollow fiber membrane module for purifying blood products, which can remove proteins contained in blood products and efficiently obtain highly safe blood products. It is aimed. The present invention has a hydrophilic polymer on the surface in contact with the blood product, the abundance of the hydrophilic polymer is 40 to 60% by mass, and the porosity on the surface is 8 to 30%. A polysulfone-based hollow fiber membrane for purifying blood products is provided.
