摘要：A mass transfer device of the type used, e.g., for blood dialysis is made bywinding on a mandrel (20) a series of fiber strands (24), each of which consists of a solidfiber (26) and one or more hollowfibers (22), the solid fiber being at least as large, and
preferably substantially larger, in diameter than the hollow fiber. As the strands arewound on the mandrel they are temporarily anchored at spaced locations along themandrel by beads of a liquid pre-potting compound which eventually harden into solidanchor plates (32). When the winding is complete, the mandrel is cut at each anchor plateto form individual temporary cartridges which can withstand the handling required inwashing and drying. After each individual cartridge is final-potted, the anchor plates (32)are discarded. and the final potting is cut in a conventional manner to form manifoldsurfaces at each end of the cartridge. A deburring treatment is then applied to themanifold surface at each end of the cartridge to smooth out any microscopicirregularities of the manifold surface which can cause thrombogenesis.
