  • Patent number: 11927587
    Abstract: A thrombelastography device, a heating apparatus, a blood coagulation analysis system, and a rotational angle measurement method are disclosed. The thrombelastography device consists of a plurality of thrombelastography device splits (2) that are horizontally arranged in parallel. The thrombelastography device split (2) comprises a worktable (4), a rack (5), a test bar (6), a tester (8), and a processor (9). The thrombelastography device overcomes the defect in the prior art that the measurement result of a thrombelastography device is inaccurate. The amount of reflected light is used as a reference for thrombelastographic evaluation, and thus the result is more accurate.

  • Patent number: 11738124
    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the donor through a draw line connected to a blood component separation device, and introduces anticoagulant into the withdrawn blood.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: 11660384
    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: 11541161
    Abstract: A method for continuously washing packed red blood cells includes (1) transferring, at a first flow rate, packed red blood cells from a container to a separation device and (2) transferring, at the same time as the packed red blood cells, wash solution from a container to the separation device. The wash solution may be transferred at a second flow rate that is greater than the first flow rate. The wash solution mixes with the packed red blood cells within the inlet line of the separation device and dilutes/washes the packed red blood cells. The separation device separates the red blood cells from the wash solution and a supernatant. The method may then monitor the volume of washed red blood cells within the separation device and begin to extract the washed red blood cells into a red blood cell product container when a target volume is collected within the separation device.

  • Publication number: 20220347677
    Abstract: A sample testing cartridge is usable to perform a variety of tests on a visco-elastic sample, such hemostasis testing on a whole blood or blood component sample. The cartridge includes a sample processing portion that is in fluid communication with a sample retention structure. A suspension, such as a beam, arm, cantilever or similar structure supports or suspends the sample retention portion relative to the sample processing portion in a unitary structure. In this manner, the sample retention portion may be placed into dynamic excitation responsive to excitation of the cartridge and correspondingly dynamic, resonant excitation of the sample contained within the sample retention portion, while the sample processing portion remains fixed. Observation of the excited sample yields data indicative of hemostasis. The data may correspond to hemostasis parameters such as time to initial clot formation, rate of clot formation, maximum clot strength and degree of clot lysis.

  • Publication number: 20210366597
    Abstract: A method for engaging a donor includes receiving, in a sewer, donor information and donation data for the donor, and sending a first communication to the donor. The first communication may be sent to the donor after completion of a donation and the method may monitor a time period after the donation to determine when a predetermined period of time has passed. The method may then generate and send a second communication to the donor after the passage of the predetermined time period. The second communication may remind the donor of that the donor is eligible to donate again and may include a preferred date and time for the donor to return to donate again. The preferred date and time may be based, at least in part, on heuristic information about the donation center's productivity. The method may also generate/send an additional message requesting a referral from the donor.
