  • Patent number: 10980934
    Abstract: A method for collecting plasma includes determining the weight, height, and hematocrit of a donor, and calculating a donor plasma volume and a target plasma collection volume. The target plasma collection volume is based on the donor plasma volume and a target percentage of plasma. The method then withdraws blood from the donor through a line connected to a blood component separation device, and introduces anticoagulant into the withdrawn blood. The blood component separation device separates the blood into a plasma component and a second blood component, and the plasma component is collected from the blood component separation device and into a plasma collection container. The method may then calculate the volume of pure plasma collected within the plasma collection container, and continue processing/collecting until the calculated volume of pure plasma equals the target plasma collection volume.

  • Patent number: 10980926
    Abstract: A method for collecting plasma includes determining the weight and hematocrit of a donor, and inserting a venous-access device into the donor. The method then withdraws blood from the donor through a draw line connected to a blood component separation device, and introduces anticoagulant into the withdrawn blood. The blood component separation device separates the blood into a plasma component and a second blood component, and the plasma component is collected from the blood component separation device and into a plasma collection container. The method may then calculate (1) a percentage of anticoagulant in the collected plasma component, and (2) a volume of pure plasma collected within the plasma collection container. The volume of pure plasma may be based, at least in part, on the calculated percentage of anticoagulant. The method may continue until a target volume of pure plasma is collected within the plasma collection container.

  • Patent number: 10954549
    Abstract: In some embodiments, the invention provides methods for detecting and/or classifying an anticoagulant at a therapeutically relevant amount or higher in a patient, including subjecting a sample of a control blood component (known not to contain the anticoagulant) to a clotting assay in the presence of a Factor Xa reagent to obtain a control clotting measurement; and subjecting a sample of a blood component from a patient suspected of having the anticoagulant to the clotting assay in the presence of the Factor Xa reagent to obtain a patient clotting measurement, wherein the patient clotting measurement sample greater than the control clotting measurement indicates the presence of the anticoagulant at a therapeutically relevant amount or higher in the patient. In some embodiments, the invention includes methods for classifying an anticoagulant as an anti-Factor Xa or a direct thrombin inhibitor anticoagulant using a clotting assay in the presence of an ecarin reagent.

  • Patent number: 10947966
    Abstract: A peristaltic pump includes a rotor and first and second rollers mounted on the rotor. The first and second rollers rotate between a disengaged, initially engaged and a fully engaged position with respect to a section of tubing. The rollers begin to occlude the tubing when in the initially engaged positon and fully occlude the tubing when in the fully engaged position. The pump also includes an encoder and a rotor controller. The encoder monitors the position of the first and second rollers as the rotor rotates. The rotor controller is in electrical communication with the encoder and controls the operation of the pump and rotor. The controller stops the rotation of the rotor in response to a stop command and based upon the monitored position of the first and second rollers such that either the first or second roller remains in the fully engaged positon.

  • Patent number: 10821220
    Abstract: A continuous flow centrifuge bowl includes a rotatable outer body, and a top and bottom core that are rotatable with the outer body. The bottom core has a wall extending proximally from a bottom wall. The proximally extending wall is radially outward from at least a portion of the top core and, together with the top core, defines a primary separation region in which initial separation of the whole blood occurs. The bowl may also have a secondary separation region located between the top core and the outer body, and a rotary seal that couples an inlet port and two outlet ports to the outer body. The inlet port may be connected to an inlet tube that extends distally into a whole blood introduction region. Additionally, one of the outlet ports may be connected to an extraction tube that extends into a region below the bottom core.

  • Patent number: 10668207
    Abstract: A method for removing fat from salvaged blood includes transferring salvaged blood from a reservoir to a blood component separation device, and separating the blood into a plurality of blood components. The method may then transfer a volume of unwashed blood components from the blood component separation device back toward the reservoir, and re-centrifuge the blood components remaining within the blood component separation device. After re-centrifuging, the method transfers additional salvaged blood from the reservoir to the blood component separation device to refill the blood component separation device. The method may then wash the components within the bowl by introducing wash solution into the blood component separation device. The wash solution displaces a volume of fat from the blood component separation device and into a waste container. The method may then empty the washed blood components within the blood component separation device to a product container.
