Publication number: 20220168486Abstract: A system for collecting plasma comprises a separator to separate whole blood from a donor into a plasma product and a second blood component, an anticoagulant line to combine anticoagulant with the whole blood, a touchscreen, and a controller. The controller is configured to receive donor parameters electronically from a donor management system. The controller is configured to use a target volume for raw plasma which is based at least in part on donor height and weight used to calculate total donor blood volume, the target volume for raw plasma based on the total donor blood volume. The controller is configured to control the system to operate draw and return phases to withdraw whole blood from a donor and return the second blood component to the donor until a volume of raw plasma in the collection container equals the target volume of raw plasma.Type: ApplicationFiled: February 18, 2022Publication date: June 2, 2022Applicant: Fenwal, Inc.Inventors: Amit J.

Patent number: 11311823Abstract: 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.Type: GrantFiled: March 3, 2020Date of Patent: April 26, 2022Assignee: Fenwal, Inc.Inventors: Benjamin E.

Patent number: 11285251Abstract: 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: July 28, 2021Date of Patent: March 29, 2022Assignee: Fenwal, Inc.Inventors: Amit J. Patel, Samantha M. Planas, Walter T. Watts, Kyungyoon Min, Daniel R. Boggs

Publication number: 20210282684Abstract: 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.Type: ApplicationFiled: May 3, 2021Publication date: September 16, 2021Inventors: Amit J.
