Abstract

Abstract Translated from French Appareillage de plasmaphérèse, pouvant être branché par une simple aiguille (1) sur un donneur et permettant de séparer le sang du donneur, grâce à un appareil (2) à membrane, en une première fraction (20) constituée de plasma, et en une deuxième fraction (17) comprenant notamment les éléments figurés du sang que l'on réinjecte (1) au donneur. Cet appareillage est caractérisé notamment par le fait de comprendre, pour la circulation du sang, deux pompes (7 et 18) disposées de chaque côté du compartiment amont (3) de l'appareil (2) à membrane et des capteurs de pression (14 et 19) auxquels lesdites pompes sont asservies. Procédé dans lequel le sang en provenance du donneur subit une première séparation, au contact de la membrane, au cours de la phase de prélèvement et dans lequel le sang subit une deuxième séparation au contact de la membrane, au cours de la phase de retour. Apparatus for plasmapheresis, which can be connected by a simple needle (1) to a donor and which makes it possible to separate the blood from the donor, by means of a membrane apparatus (2), into a first fraction (20) consisting of plasma, and into a second fraction (17) comprising in particular the figured elements of the blood which is reinjected (1) to the donor. This apparatus is characterized in particular by the fact of comprising, for the circulation of blood, two pumps (7 and 18) arranged on each side of the upstream compartment (3) of the device (2) with membrane and pressure sensors (14 and 19) to which said pumps are controlled. Method in which the blood coming from the donor undergoes a first separation, in contact with the membrane, during the collection phase and in which the blood undergoes a second separation in contact with the membrane, during the return phase.
