  • Patent number: 11957828
    Abstract: Blood is conveyed from a source into a separator, which separates at least one target blood component from the blood. The target blood component is then conveyed out of the separator, with the procedure continuing until an initial target amount of blood to be processed has been conveyed from the source into the separator and the target blood component separated from the initial target amount of blood to be processed has been conveyed out of the separator as an actual yield of the target blood component. An adjusted target amount of blood to be processed is then determined based at least in part on the difference between a target yield of the target blood component and the actual yield. The initial target amount of blood to be processed is then replaced with the adjusted target amount of blood to be processed when next executing the procedure.

  • Publication number: 20240023855
    Abstract: A plasmapheresis system and a method for operating a plasmapheresis system are provided by which a volume of plasma product (i.e., anticoagulated plasma) so that that the targeted volume of pure plasma in the plasma product is determined based on donor-specific characteristics. In particular, the targeted amount of pure plasma to be collected is based on the weight, or the weight and the height, of the donor. The targeted volume of pure plasma to be collected, TVP, may be a multiple of the donors weight. Alternatively, TVP may be a multiple of the donor's total blood volume, TBV, with the TBV of the donor being determined based on the donor's weight and height. A target volume for the plasma product to be collected, TVPP, is established, and separation of whole blood into a plasma component and a second component continues until the volume of plasma product in a collection container equals TVPP.

    Abstract: Described is a method for controlling fluid volume balance. A controller is configured with a first set of inputs comprising a hematocrit, a total blood volume, and an ACD ratio. A maximum extracorporeal RBC amount during the procedure is estimated based on the first set of inputs. A fluid circuit is primed with a priming fluid. Whole blood is drawn from a blood source and separated into a RBC component, a target cell component, and a plasma component. The target cell component is directed to a product container. The product container comprising the target cell component is treated. A treated target cell component, a portion of the RBC component remaining in the fluid circuit, and/or a portion of the plasma component remaining in the fluid circuit are returned to the blood source. A first response action is provided if the maximum extracorporeal RBC amount estimated is above a programmed limit.
