Abstract

L'appareil comprend : un logement 100 comportant une entrée de sang 110 destinée à être raccordée à une source de sang, une sortie de sang 120 en communication de fluide avec l'entrée de sang, et une sortie de fraction de sang; une membrane semi-perméable 180 qui sépare la sortie de fraction de sang de l'entrée et de la sortie de sang et qui permet à la fraction de sang de la traverser; et une plaque perforée 150 qui envoie des jets de sang très rapides vers et le long d'une surface 181 de la membrane de façon à empêcher la membrane de se colmater au point que la fraction de sang ne puisse plus la traverser. Recueil du plasma, du sérum, des immuno-globulines, etc.The apparatus comprises: a housing 100 having a blood inlet 110 for connection to a source of blood, a blood outlet 120 in fluid communication with the blood inlet, and a blood fraction outlet; a semi-permeable membrane 180 which separates the blood fraction outlet from the blood inlet and outlet and which allows the blood fraction to pass therethrough; and a perforated plate 150 which sends very rapid jets of blood to and along a surface 181 of the membrane so as to prevent the membrane from becoming clogged to the point that the blood fraction can no longer pass through it. Collection of plasma, serum, immunoglobulins, etc.
