  • 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: 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.
