Patent number: 11666926Abstract: Mid-procedure termination of a mononuclear cell collection procedure may prevent collection of an amount of red blood cells that is required to harvest a complete mononuclear cell product. Blood separation systems and methods are provided for minimizing the impact of or recovering from mid-procedure termination of such a mononuclear cell collection procedure. According to one approach, blood or separated red blood cells are conveyed into a red blood cell collection container relatively early in the procedure to minimize the impact of a later termination of the procedure. According to another approach, blood and/or separated red blood cells within a fluid processing assembly are redirected through the fluid processing assembly following mid-procedure termination to allow for at least partial mononuclear cell collection.Type: GrantFiled: January 7, 2021Date of Patent: June 6, 2023Assignee: Fenwal, Inc.Inventors: Lan T.

Publication number: 20220400992Abstract: 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.
