Patent number: 11925736Abstract: Dialyzer systems can consolidate multiple technologies and functionalities of blood treatment systems in a significantly integrated fashion. For example, this disclosure describes dialyzer systems that include a magnetically driven and magnetically levitating pump rotor integrated into the dialyzer. Such a dialyzer can be used with treatment modules that include a magnetic field-generating pump drive unit. In some embodiments, the dialyzers include pressure sensor chambers with flexible membranes with which corresponding pressure transducers of the treatment modules can interface to detect arterial and/or venous pressures.Type: GrantFiled: November 12, 2020Date of Patent: March 12, 2024Assignees: Fresenius Medical Care Deutschland GmbH, Fresenius Medical Care Holdings, Inc.Inventors: Massimo Earl Fini, Lynn E. Jensen, Alexander Heide, Dejan Nikolic, Arne Peters, Christoph Wiktor, Marina Wenke, Tommy Huang, Dacey John Ryan, Stefan Kreber, Lothar Leick, Dzhuney Terzi, Hendrik Therre, Manfred Weis, Alain Veneroni, Reinhold Reiter, Michele Marini, Davide Maria Benelli, Brad Yang, Jiunn Teo
