A pneumatic pump manifold disposable system, configured as a cassette, is used for the purpose of red cell and plasma apheresis. The cassette (16) integrates a separation device (44) such as a spinning membrane separator, a controller and a fluid flow circuit (42) for the purpose of separating plasma and red cells from the whole blood. The cassette system, with the separation device (44) directly attached without tubing, simplfies the loading of the disposable set into the hardware such as a case (20), and reduces the manufacturing complexity of the set. The system allows for plasma, buffy coat and red cells to be stored in long term storage containers (54, 56 and 58) after a procedure.

L'invention concerne un système de collecteur jetable à pompe pneumatique configuré sous forme de cassette, et utilisé pour exécuter l'aphérèse des globules rouges et du plasma. Cette cassette comprend un dispositif de séparation, un système de collecteur, un filtre de macro-agrégats, et cinq chambres de pompage destinées à séparer le plasma et les globules rouges contenus dans le sang. Le système de cassette à dispositif de séparation, fixé directement sans tuyau, simplifie le chargement de l'ensemble jetable dans le matériel, et réduit la complexité de sa fabrication. Ce système permet de stocker le plasma, le plasma et les globules rouges, ou uniquement les globules rouges dans des récipients de stockage à long terme après la procédure de séparation.
