  • 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.

  • Publication number: 20230402171
    Abstract: A system and method for collecting plasma includes drawing whole blood from a donor, combining anticoagulant with the whole blood from the donor, separating the whole blood into a plasma product and a second blood component and sending the plasma product to a collection container. A controller determines a total blood volume for a donor based on donor weight, height and gender. The system comprises a touchscreen for receiving a confirming user input and a scanning device configured to scan a bar code associated with a donor. The system and method operate a plurality of draw and return phases.

  • Patent number: 11837357
    Abstract: A system and method for collecting plasma includes drawing whole blood from a donor, combining anticoagulant with the whole blood from the donor, separating the whole blood into a plasma product and a second blood component and sending the plasma product to a collection container. A controller receives parameters over a network from a remote computer, receives a user input to confirm the a parameter and/or procedure, determines a target volume for plasma product and/or raw plasma based on the parameters and, in response to confirming the donor, controls the system to collect the plasma using draw and return phases.

  • Publication number: 20230321334
    Abstract: A blood separation device has a controller configured to execute a first and a second version of a blood separation procedure. Information regarding a blood source is analyzed to determine whether to implement the first version of the procedure or the second version. This may include an analysis of the age, weight, and/or sex of the blood source, along with whether the blood source has previously been the subject of a blood separation procedure. The second version may allow for a greater percentage of the blood or red blood cells of the blood source to be outside of the body of the blood source (in a fluid flow circuit mounted to the device) at any time during the procedure. The second version may also or alternatively allow for a higher blood cell separation efficiency than the first version, along with separating the blood in a larger blood separation chamber.

  • Patent number: 11730873
    Abstract: A method of collecting plasma includes receiving donor parameters at a controller of a plasma collection device electronically from a donor management system. The method includes storing a target volume for raw plasma which is based at least in part on donor height and weight used to calculate total donor blood volume, the target volume for raw plasma based on the total donor blood volume. The method includes setting the target volume for raw plasma and controlling the plasma collection device to operate draw and return phases to withdraw whole blood from a donor and separate the whole blood into the plasma product and a second blood component comprising red blood cells and to return the second blood component to the donor. The controller operates the draw and return phases until a volume of raw plasma in the collection container equals the target volume of raw plasma.

  • Publication number: 20230106739
    Abstract: A blood separation system is provided with a data entry device, a blood separator, a pump system, and a controller. The controller compares data regarding a blood source that is received by the data entry device and/or calculated values derived from the data to a target range, a maximum value, and/or a minimum value. The controller requests reentry or confirmation of at least a portion of the data when the data or calculated value is outside of the target range, less than the minimum value, and/or greater than the maximum value. The controller instead proceeds with a blood separation procedure when the data or calculated value is not outside of the target range, less than the minimum value, and/or greater than the maximum value or after determining that there have been no data entry errors.

  • Patent number: 11383013
    Abstract: A plasmapheresis system and a method for operating a plasmapheresis system are provided by which the volume/weight of anticoagulated plasma that is collected is optimized. In one example, a nomogram is provided that utilizes the donor's hematocrit to calculate the volume/weight of raw plasma within a plasma product having the maximum volume permitted by the FDA nomogram. In a plasmapheresis procedure having multiple collection phases followed by a reinfusion cycle in which concentrated red blood cells are returned to the donor, the volume of plasma product to be collected is calculated prior to the start of each collection cycle to account for the donor's increasing hematocrit, thus resulting in a greater total volume of plasma product to be collected during the plasmapheresis procedure.

  • Publication number: 20220176025
    Abstract: During a first stage of a priming procedure, a priming fluid is conveyed into a spinning membrane separator via a filtrate outlet port so as to convey air out of the spinning membrane separator via an inlet port and a retentate outlet port of the spinning membrane separator. During an optional second stage of the priming procedure, the priming fluid is conveyed into the spinning membrane separator via the inlet port so as to convey air out of the spinning membrane separator via the retentate outlet port. A rotor positioned within a housing of the spinning membrane separator may be rotated with respect to the housing during the first and second stages to force air from within the rotor into an annulus defined between the rotor and the housing for more complete priming of the spinning membrane separator.

  • Patent number: 11298446
    Abstract: A method is provided for calibrating a pump during a blood separation procedure that has at least a first and second state or phase where fluid is flowed to or from a reservoir by action of the pump. The state or phase of the procedure may be a priming state, a draw state, a separation state and a return state, and the pump calibration may be performed between consecutive performances of the same procedure state. The calibration is based on a variance between the volume of fluid predicted to be processed by the pump for the given state of the procedure and the actual volume processed based on the change of weight of the reservoir. Recalibration of the pump, if necessary, is accomplished before the performance of the second phase is commenced.
