Patent number: 10569000Abstract: A method includes: receiving measurements of a blood-related parameter corresponding to a patient undergoing hemodialysis; estimating a value of one or more hemodialysis treatment-related parameters by applying a vascular refill model based on the received measurements of the blood-related parameter, wherein the one or more hemodialysis treatment-related parameters are indicative of an effect of vascular refill on the patient caused by the hemodialysis; determining, based on the one or more estimated values of the one or more hemodialysis treatment-related parameters, a hemodialysis treatment-related operation; and facilitating performance of the treatment-related operation. The vascular refill model is a two-compartment model based on a first compartment corresponding to blood plasma in the patient's body, a second compartment based on interstitial fluid in the patient's body, and a semi-permeable membrane separating the first compartment and the second compartment.Type: GrantFiled: May 29, 2015Date of Patent: February 25, 2020Assignee: Fresenius Medical Care Holdings, Inc.Inventors: Aurelio A. De los Reyes, V, Doris H. Fuertinger, Franz Kappel, Anna Meyring-Wosten, Stephan Thijssen, Peter Kotanko

Patent number: 10525182Abstract: The disclosed subject matter relates to extracorporeal blood processing or other processing of fluids. Volumetric fluid balance, a required element of many such processes, may be achieved with multiple pumps or other proportioning or balancing devices which are to some extent independent of each other. This need may arise in treatments that involve multiple fluids. Safe and secure mechanisms to ensure fluid balance in such systems are described.Type: GrantFiled: October 9, 2015Date of Patent: January 7, 2020Assignee: NxStage Medical, Inc.Inventors: Jeffrey H. Burbank, Dennis M. Treu, Daniel J. Rubery, Jr., Scott W. Newell, James M. Brugger, William J. Schnell, William K. Weigel, Steve A. White, Mark T. Wyeth, Jerome James, David Desouza, Joseph E.

Patent number: 10507279Abstract: A control system (23) is arranged to control the operation of an apparatus (200) for extracorporeal blood treatment. The apparatus (200) comprises an extracorporeal blood circuit (20) and a connection system (C) for connecting the blood circuit (20) to the vascular system of a patient. The blood circuit (20) comprises a blood processing device (6), and at least one pumping device (3). The control system is operable to switch between a pre-treatment mode and a blood treatment mode. The blood treatment mode involves operating the blood circuit (20) to pump blood from the vascular system via the connection system (C) through the blood processing device (6) and back to the vascular system via the connection system (C). The control system (23) is operable to obtain measurement data from at least one energy transfer sensor (40) arranged to sense a transfer of energy between the patient and the connection system (C) or between the patient and the blood circuit (20).Type: GrantFiled: October 31, 2017Date of Patent: December 17, 2019Assignee: Gambro Lundia ABInventors: Bo Olde, Kristian Solem, Thomas Hertz, Jan Sternby, Anders Wieslander
