[0002] At present, hemodialyzers are commonly used to treat acute and chronic kidney diseases. Their specific functions are hemodialysis and hemofiltration. They are mainly composed of a shell, a polymer fiber membrane inside the shell, red and blue end caps and sealing rings.

[0003] In one of the processes in producing hemodialyzers, polyurethane is poured into the shell to fix the hollow fiber membrane inside the shell.
