  • 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.

  • Patent number: 11826677
    Abstract: Blood in a separation chamber is separated into a red blood cell layer, a plasma constituent, and a mononuclear cell-containing layer. A portion of the plasma constituent exits the chamber via a plasma outlet, while a first portion of the red blood cell layer exits via a red blood cell outlet. A second portion of the red blood cell layer exits the chamber via the red blood cell outlet and is collected. At least a portion of the collected red blood cell layer may then be conveyed to the chamber via the red blood cell outlet to convey at least a portion of the mononuclear cell-containing layer out of the chamber via the plasma outlet for collection. A second portion of the plasma constituent may be conveyed out of the chamber via the plasma outlet to more fully collect the mononuclear cell-containing layer without the use of collected plasma.

  • Patent number: 11801001
    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 donor's 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: 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.

  • Publication number: 20230285643
    Abstract: A method (and a system for implementing such method) for creating a plurality of fluid products each having a minimum content of a fluid component includes providing a plurality of intermediate fluid volumes each having a known content of a fluid component. The intermediate fluid volumes are grouped by fluid component content, followed by a determination of whether two of the intermediate fluid volumes may be pooled to achieve the minimum content for a final fluid product. The method proceeds with creating combinations of three and then more intermediate fluid volumes achieving the minimum content for a final fluid product, followed by creating combinations of intermediate fluid volumes exceeding the minimum content. Each intermediate fluid volume is assigned to only one of the combinations, with the intermediate fluid volumes being assigned to the combinations so as to maximize the number of combinations and, thus, the number of final fluid products.

  • Publication number: 20230271198
    Abstract: Fluid separation chambers are provided with a central hub, with generally annular low-G and high-G walls extending about the hub to define therebetween a separation channel. A plurality of radial walls extend from the hub to the channel to define an inlet passage, two outlet passages, and a terminal wall separating an upstream end of the separation channel from a downstream end of the channel. The radius of the high-G wall is greater at the downstream end of the separation channel than at the upstream end, which may include the radius gradually increasing along a tapered section of the high-G wall. The tapered section may extend from the upstream end of the separation channel to the downstream end of the channel or along a smaller length of the channel. The radius of the low-G wall may similarly increase from the upstream end of the separation channel to the downstream end.

  • Patent number: 11731371
    Abstract: A sterile connection device includes first and second carriages. The first carriage defines a first portion of a proximal slot and a first portion of a distal slot, while the second carriage defines second portions of the proximal and distal slots. A controller executes a sterile connection procedure in which a solid cutting blade is heated, followed by the heated blade being moved to a cutting position to cut sealed proximal and distal tubes received by the slots. The second carriage moves proximally or distally with respect to the first carriage so as to align the cut ends of the tubes. The heated blade then moves out of the cutting position, followed by the first carriage moving toward the second carriage so as to press the cut ends of the tubes into contact with each other so as to sterilely connect the cut ends and define a joined tube.

  • Publication number: 20230044027
    Abstract: Systems and methods are provided for separating platelets from blood. Prior to blood separation, a volume of blood to be processed, a volume of platelets to be collected, and/or a time required to complete blood draw from a source during a blood separation procedure is determined. Based on that determination, a procedure setpoint is calculated from the completion of the blood draw. Blood is subsequently drawn from a source into a separator in which the blood is separated into a mononuclear cell-containing fraction and a platelet-containing fraction. At least a portion of the platelet-containing fraction is conveyed from the separator, while the volume of the mononuclear cell-containing fraction in the separator increases. The mononuclear cell-containing fraction is conveyed to the source from the separator at the procedure setpoint. The blood draw and separation are then ended.

  • Publication number: 20230011431
    Abstract: A fluid separation device includes a centrifuge in which a fluid is separated into at least two components, with an interface therebetween. At least a portion of one of the separated fluid components is removed from the centrifuge and flows through a vessel. Light is reflected off of the separated fluid component in the vessel and received and analyzed to determine its main wavelength. If the main wavelength is higher than a maximum value, a target location of the interface is changed. If the main wavelength is less than the maximum value, then the location of the interface is compared to the target location. When the interface is sufficiently close to the target location, the optical density of the separated fluid component in the vessel is compared to a minimum value. If the optical density is less than the minimum value, the target location of the interface is changed.

  • Publication number: 20220409799
    Abstract: A processing device includes a pump system, a valve system, a centrifuge, and a controller. A fluid flow circuit is mounted to the device to execute a procedure in which whole blood is processed into a red blood cell product, a plasma product, and a platelet concentrate product. The blood is first separated into red blood cells, buffy coat, and plasma using the centrifuge, with the red blood cells and plasma being removed from the centrifuge, while the buffy coat remains in the centrifuge. The fluid remaining in the centrifuge is circulated through the centrifuge to form a homogenous mixture. Once the mixture is formed, it is separated in the centrifuge into platelet concentrate and red blood cells. A platelet product is then collected by using whole blood or previously collected red blood cells to push the platelet concentrate from the centrifuge to a collection container.
