Systems and methods for monitoring and controlling fluid balance during a biological fluid procedure
Patent number: 11857714Abstract: Described is a method for controlling fluid volume balance. A controller is configured with a first set of inputs comprising a hematocrit, a total blood volume, and an ACD ratio. A maximum extracorporeal RBC amount during the procedure is estimated based on the first set of inputs. A fluid circuit is primed with a priming fluid. Whole blood is drawn from a blood source and separated into a RBC component, a target cell component, and a plasma component. The target cell component is directed to a product container. The product container comprising the target cell component is treated. A treated target cell component, a portion of the RBC component remaining in the fluid circuit, and/or a portion of the plasma component remaining in the fluid circuit are returned to the blood source. A first response action is provided if the maximum extracorporeal RBC amount estimated is above a programmed limit.Type: GrantFiled: January 23, 2023Date of Patent: January 2, 2024Assignee: Fenwal, Inc.Inventors: Zahra R Ali, Lan T.

Patent number: 11850604Abstract: A fluid separation device includes a centrifuge in which a fluid is separated into at least two components, with an interface therebetween. At least a portion of one of the separated fluid components is removed from the centrifuge and flows through a vessel. Light is reflected off of the separated fluid component in the vessel and received and analyzed to determine its main wavelength. If the main wavelength is higher than a maximum value, a target location of the interface is changed. If the main wavelength is less than the maximum value, then the location of the interface is compared to the target location. When the interface is sufficiently close to the target location, the optical density of the separated fluid component in the vessel is compared to a minimum value. If the optical density is less than the minimum value, the target location of the interface is changed.Type: GrantFiled: September 23, 2022Date of Patent: December 26, 2023Assignee: Fenwal, Inc.Inventors: Benjamin E. Kusters, Richard I. Brown, Kyungyoon Min

Patent number: 11801001Abstract: 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: GrantFiled: July 11, 2022Date of Patent: October 31, 2023Assignee: FENWAL, INC.Inventors: Amit J.
