Patent number: 12144624Abstract: 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.Type: GrantFiled: September 22, 2023Date of Patent: November 19, 2024Assignee: FENWAL, INC.Inventors: Amit J.

Patent number: 11383013Abstract: 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.Type: GrantFiled: January 10, 2020Date of Patent: July 12, 2022Assignee: Fenwal, Inc.Inventors: Amit J.
