WebNov 25, 2024 · Hollow-fiber dialyzers consist of thousands of cylindrical fibers separating blood from the dialyzing fluid, while maximizing the surface area for fluid and solute exchange. The fiber membranes allow the passage of water and small solutes, but not of red blood cells (RBC) and macromolecules such as albumin. WebSubsequently, the fibers that eventually serve as the collective membrane in the dialyzer are assembled (“bundled”) and inserted in the dialyzer casing. The fiber bundle then is “potted” (encapsulated) at both ends with silicone rubber and cut. Finally, the dialyzer is placed in a pouch and the entire unit is sterilized, usually by ...
