Hollow fibre membrane and dialysis machine

摘要

The hollow fiber membrane has a radial layered structure which consists of layer A and layer B. The internal diameter of the hollow fiber membrane lies in the range between 180 micrometer and 210 micrometer and the wall thickness of the fully fibered membrane lies between 25 micrometer and 45 micrometer. The layer B is formed as selective separation layer which has layer thickness between 0.1 micrometer and 5 micrometer. Layer A has layer thickness between 20 micrometer and 50 micrometer and is formed as a porous support- or carrier layer for layer B. The layer B has a pore structure.
