A system and method are used in connection with processing of blood components. The processing of blood components may involve centrifugal separation and/or filtering of the blood components. In some examples, at least some blood components are centrifugally separated in a chamber and then filtered via a filter (31) rotating along with a centrifuge rotor (1), wherein the filter is located closer than the chamber to an axis of rotation of the rotor. The filter may include a porous filtration medium configured to filter leukocytes, platelets, and/or red blood cells. Some examples include a pressure sensor sensing pressure of pumped blood components. The sensed pressure may be used in connection with controlling the pumping of the blood products and/or in connection with determining the location of an interface associated with the blood products. Other uses of the sensed pressure are also possible.

L'invention concerne un système et un procédé utilisés dans le cadre du traitement des composants sanguins. Ce traitement peut comprendre la séparation par centrifugation et/ou la filtration des composants sanguins. Dans certains exemples, au moins certains composants sanguins sont séparés par centrifugation dans une chambre, puis filtrés au moyen d'un filtre tournant avec un rotor centrifuge, ce filtre étant situé plus près d'un axe de rotation du rotor que la chambre. Ledit filtre peut comprendre un milieu filtrant poreux conçu pour filtrer les leucocytes, les plaquettes et/ou les globules rouges. Certains exemples comprennent un capteur de pression servant à capter la pression des composants sanguins pompés. La pression captée peut être utilisée dans le cadre d'un contrôle du pompage des produits sanguins et/ou pour déterminer l'emplacement d'une interface associée aux produits sanguins. D'autres utilisations de la pression captée sont également possibles.
