ABSTRACT:
A method of blending two different sizes or two different types of hollow fiber membranes provides hemodialyzers with specifiable characteristics utilizing standardized housings. The system can blend two different fiber sizes of the same type to achieve a desired ultrafilteration rate in a standard housing. This system can also blend two different types of fibers to be used in a standardized housing to provide a desired ultrafiltration rate.
