    摘要: Systèmes et procédés de récupération de cellules sanguines, sensiblement exemptes de substances indésirées, utilisant un premier conteneur (16) qui forme une partie du système de récupération de sang (10) pour récupérer une quantité de cellules sanguines. Un système de filtration (14) est ensuite fixé à ce premier conteneur. Le système de filtration (14) comprend un second conteneur (34), un premier chemin de fluide (36) qui mène au second conteneur (34) au travers d'un dispositif de filtration (40) et un second cheminement de fluide (38) qui mène au second conteneur (34) en bypassant le dispositif de filtration (40). Les cellules sanguines sont acheminées depuis le premier conteneur (16) au travers du premier chemin de fluide (36) et du dispositif de filtration (40) pour arriver dans le second conteneur (34) et séparer les substances indésirées des cellules sanguines. Les cellules sanguines exemptes de substances indésirées sont alors acheminées depuis le second conteneur (34) en passant par le second chemin de fluide (38), en bypassant le dispositif de filtration (34) pour revenir dans le premier conteneur (16). Le système de filtration (14) est ensuite détaché du système récupérateur de sang (10).

    摘要: Filtration of white blood cells (WBCs) directly from platelet rich plasma (PRP) rather than from subsequently made platelet concentrates (PC). Earlier filtration is effective at removing most WBCs with minimal platelet loss and permits storage of platelets for at least 5 days. The filtration is preferably done with a closed, ready-to-use system comprising a WBC filter (11) disposed between a first blood bag (3) and at least two empty secondary bags (15a,15b). A fourth bag (21) may be included in the closed system to contain a platelet additive solution (17). System can remove at least 95% of the WBCs with less than 10% loss in platelets. In very preferred embodiments at least 99.5% of the original WBCs are removed by filtration prior to platelet storage.

    摘要: Blood is separated into blood components aseptically in a closed system by first filtering whole blood from a collector (1) through a filter (2) for removing leukocytes or removing leukocytes and platelets, to produce filtered blood, which is passed to and collected in a primary bag (3) fluid-tightly connected to the filter (2) through a sealable, cuttable conduit (9), and the conduit (9) is sealed and cut to disconnect the primary bag (3) from the filter (2). The disconnected primary bag (3) is subjected to centrifugation to separate the filtered blood into blood components. The separated plasma may be transferred through a sealable, cuttable conduit (10) to a satellite bag (4). The procedure is useful for separately collecting leukocyte-removed erythrocytes, leukocyte-removed plasma, leukocyte-removed platelets, etc., from the whole blood of a healthy human.

    摘要: A blood component collection system (10, 12) which comprises first means (14) for collecting whole blood from a donor for separation into essentially red blood cells and platelet-rich plasma. The system (10, 12) also includes second means (16) for receiving the platelet-rich plasma from the first means (14) and for noncentrifugally separating the platelet-rich plasma into platelet concentrate and virtually platelet-free plasma. The blood component collection system (10, 12) which embodies the first means (14) and second means (16) of the invention is applicable for use in the context of either a nonautomated batch centrifugation process (10) or a continuous flow procedure (12).
