Abstract

Abstract Translated from French Le dispositif (5) est essentiellement constitué d'un faisceau de fibres creuses capillaires, de préférence des fibres de cellulose ou de copolymère d'alcool éthylène-vinylique, à l'intérieur desquelles est fixé par covalence un ligand sélectif pour la substance, anticorps ou antigène, à éliminer ou récupérer, présente dans le sang. Pour purifier le sang par circulation extra-corporelle "in vivo", on le prélève par exemple dans l'artère fémorale (1), on ajoute l'héparine (3) avant de le faire passer à travers le dispositif (5) puis on le dégaze (7) et le renvoie dans la veine fémorale (10). The device (5) essentially consists of a bundle of hollow capillary fibers, preferably fibers of cellulose or of ethylene-vinyl alcohol copolymer, inside which is fixed covalently a ligand selective for the substance, antibody or antigen, to be eliminated or recovered, present in the blood. To purify the blood by extra-bodily circulation "in vivo", it is taken for example from the femoral artery (1), heparin (3) is added before passing it through the device (5) and then degas (7) and returns it to the femoral vein (10).
