摘要:
Method for separating a volume of composite liquid into at least a first component and a second component including centrifuging a separation bag 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; 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 into at least one component bag connected to the separation bag; 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:
A method for controlling a centrifuge blood component separation system for separating components of a blood product, the separation system comprising a centrifuge and a separation bag and at least one transfer bag. The method comprises selecting a nominal hematocrit value such that an actual hematocrit value is expected to be less than said nominal hematocrit; centrifuging a separation bag containing a volume of composite liquid so as to cause the sedimentation of at least a first component and a second component; transferring some of the first component to a first transfer bag; detecting time of passage of a red blood cell interface at a pre-selected location in the separation bag; and adjusting a predicted processing time based on the time of passage of the red blood cell interface.
摘要:
A centrifugal blood separation system comprising a rotor, a light source, an optical sensor, a control system, a separation vessel, and an optical cell on the separation vessel. The optical cell has a first extraction port extending radially outwardly into the optical cell, a red blood cell extraction port downstream from the first extraction port and extending into the optical cell beyond the first extraction port; and a dam 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 having a first diameter, a lumen having a second diameter smaller than the first diameter, and a frustro-conical passageway coupling the bore to the lumen.
摘要:
A method and apparatus for separating a volume of whole blood contained in a separation bag into at least three components comprising centrifuging the separation bag so as to separate therein a first inner layer comprising plasma, a second intermediate layer comprising platelets, a third intermediate layer comprising lymphocytes, monocytes and granulocytes and a fourth outer layer comprising red blood cells, transferring, into a plasma component bag connected to the separation bag, a plasma component and transferring into a mononuclear cell component bag a mononuclear cell components.
摘要:
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 rotating along with a centrifuge rotor, 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.
