DIALYSAPPARAT FOR OVERFORING ELLER KVARHALLNING AV EMNEN I EN FORSTA VETSKA TILL ELLER FRAN EN ANDRA VETSKA GENOM ETT ROR ELLER EN MEMBRANVEGG

摘要

A compact dialyzer has capillary tubes orderly arranged in layers to provide a large surface area for dialysis in a small volume. Each layer of capillary tubes consists of a single row of parallel tubes whose axes are angularly disposed to the axes of the tubes in each of the two adjacent layers. The axes of the tubes of alternate layers are parallel. The dialyzer is manifolded such that a first-fluid passes through all the capillary tubes while a second-fluid passes over the capillary tubes between the layers. The capillary tubes can be channels defined between the peaks of a top pleated sheet of a semipermeable membrane and a bottom flat sheet of the semipermeable membrane to which the pleated sheet has been bonded.
