摘要:
A centrifugal blood separation system comprising a rotor (21), a light source (12), an optical sensor (16), a control system (34), a separation vessel (20), and an optical cell (180) on the separation vessel. The optical cell has a first extraction port (182) extending radially outwardly into the optical cell, a red blood cell extraction port (186) downstream from the first extraction port and extending into the optical cell beyond the first extraction port; and a dam (192) between said first extraction port and said red blood cell extraction port, having an upper edge and a lower edge, wherein the first extraction port and the red cell extraction port are radially between the upper edge and the lower edge of the dam. Also, a first extraction port having a bore (216) having a first diameter, a lumen (212) having a second diameter smaller than the first diameter, and a frustro- conical passageway (214) coupling the bore to the lumen.
摘要:
A disposable blood separation set and a centrifugal blood processing system comprising a blood processing chamber adapted to be mounted on a rotor of a centrifuge; a frustro-conical cell separation chamber in fluid communication with the processing chamber, the cell separation chamber having an inlet, and outlet and a side tap outlet adjacent the inlet. The inlet may protrude into the cell separation chamber forming a circumferential well surrounding the protruding inlet. The side tap outlet may connect to the well. The set and system comprise means for selectively drawing fluid from either the outlet or the side tap outlet.

A bag loading means (87) is for loading and unloading at least one satellite bag (2, 3, 4) into and from the central compartment (34) of a rotor (32, 33, 34, 35) of an apparatus for separating a composite liquid into at least two components. The bag loading means (87) comprises an upper part comprising securing means (92) for removably securing an upper portion of at least one satellite bag (2, 3, 4) to the bag loading means (87); a lower part comprising a receptacle (96) for containing a lower portion of at least one satellite bag (2, 3, 4); and an intermediate part connecting the upper part to the lower part and exposing an intermediate portion of a satellite bag (2, 3, 4) having an upper portion secured to the upper part of the loading means (87) and a lower portion inserted in the receptacle.
摘要:
Method and apparatus for separating a volume of whole blood into at least a plasma component and a red blood cell component comprising centrifuging a separation bag (1) containing a volume of whole blood so as to separate therein at least a first component comprising plasma and a second component comprising red blood cells; transferring the first component into a plasma component bag (4) during centrifugation of the separation bag (1); transferring into the separation bag (1) a volume of wash solution from a wash solution bag (3) during centrifugation of the separation bag (1); mixing the volume of wash solution with the second component; centrifuging the separation bag (1) so as to separate therein a washed red blood cell component and a supernatant component; and transferring the supernatant component into a waste bag (2; 3) during centrifugation of the separation bag (1).

摘要:
Method and apparatus for separating a volume of composite liquid into at least a first component and a second component including centrifuging a separation bag (1) containing a volume of composite liquid and a volume of gas so as to sediment at least a first component and a second component separation bag (1); displacing a volume of hydraulic fluid against the separation bag to cause a transfer of at least one fraction of the content of the separation bag (1) into at least one component bag (2, 3, 4, 5) connected to the separation bag (1); determining the volume of hydraulic fluid displaced and determining the volume of the composite liquid or the transferred components from the determined volume of displaced hydraulic fluid.
摘要:
An apparatus for separating a volume of composite liquid into at least a first component and a second component comprises a centrifuge having a rotor (32, 33, 34, 35). The rotor comprises a turntable (35) for supporting a separation bag (1) and a central compartment (34) for containing satellite bags connected to the separation bag (1). The central compartment is fitted with a support member (87) for supporting at least one satellite bag (2, 3) so that a liquid contained in the supported satellite bag (2, 3) drains from the supported satellite bag (2, 3) into the separation bag (1) under centrifugation forces when the rotor (32, 33, 34, 35) is set in rotation.

摘要:
A bag assembly for the separation of a composite liquid into at least two components, comprises a set of bags and a bag-assembling device (40) for assembling the set of bags. The set of bags comprises a separation bag connected by a product tube to at least one product bag. The bag-assembling device (40) comprises a support member (41); a mounting means (43, 44), connected to the support member (41), for removably mounting the bag-assembling device (40) in a rotor of a centrifuge having a central cavity for containing the product bag; and a first securing means (46, 47) connected to the support member (41) for releasably securing the product bag (2, 3, 4, 26) to the support member (41). The mounting means (43, 44) and the first securing means (46, 47) are so arranged that the product bag occupies a determined position in the central cavity of a rotor when the bag-assembling device (40) in mounted therein.
