CA 2604005

Described herein is a continuous-flow centrifuge (CFC) which may be embodied in an automated system for collecting and separating whole blood into its components. The collection and separation system includes a console and a disposable set. Various blood processing procedures which produce specific blood products may be implemented by using a specific disposable set for each process. The continuous-flow centrifuge disk, comprising: an inner wall, an outer wall, and a separation channel therebetween, comprising: an inner surface (506), an outer surface (507), an inlet port (594) to introduce whole blood into said separation channel, a first outlet port (544) to remove concentrated red blood cells from said separation channel and a second outlet (584) to remove plasma from said separation channel, wherein said inner surface and said outer surface of said separation channel are each independently configured at a non-zero angle relative to a spin axis.

L'invention concerne une centrifugeuse à flux continu (CFC) pouvant être mise en oeuvre au sein d'un système automatisé de collecte et de séparation de sang complet en ses composants. Le système de collecte et de séparation comprend une console et un ensemble jetable. Diverses procédures de traitement du sang produisant des produits sanguins spécifiques peuvent être mises en oeuvre au moyen d'un ensemble jetable spécifique pour chaque processus. Le disque de centrifugeuse à flux continu, comprend : une paroi intérieure, une paroi extérieure et un canal de séparation entre celles-ci, comportant : une surface intérieure (506), une surface extérieure (507), un orifice d'admission (594) pour introduire le sang complet dans ledit canal de séparation, un premier orifice de sortie (544) pour retirer les globules rouges concentrés dudit canal de séparation et une deuxième sortie (584) pour retirer le plasma dudit canal de séparation, ladite surface intérieure et ladite surface extérieure dudit canal de séparation étant chacune indépendamment configurée à un angle non nul par rapport à un axe de rotation.
