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.

Patent number: 10363408Abstract: A screw connector for medical hose systems is configured for catch engagement in a half-open sterilization position. The connector includes a first connecting element having a first lumen and an outside thread, and a second connecting element having a second lumen, and an elastically deformable union nut having an inside thread. The inside thread and the outside thread are configured to be screwed together, with the outside thread having a first formation and the inside thread a second formation, with deformation of the nut via the first formation in a predetermined first angle-of-rotation range without engaging the second formation. The inside thread and the outside thread, and the first formation and the second formation, are configured for catch engagement of the first formation in the second formation when the inside thread and the outside thread are screwed together in a predetermined second angle-of-rotation range to provide the half-open sterilization position.Type: GrantFiled: February 24, 2015Date of Patent: July 30, 2019Assignee: FRESENIUS MEDICAL CARE DEUTSCHLAND GMBHInventors: Uwe Lapp, Lothar Leick, Ralf Mueller, Peter Urban

Patent number: 5558769Abstract: A latching apparatus is provided for a bearing assembly in which at least three bearing rollers, each of which is supported in a rotating fashion on a bearing journal, are arranged rotationally symmetrical and lying in one plane and guide and support a bearing race between them. The bearing journals are arranged on a carrier device that is in turn supported in a rotating fashion on a central axle aligned with the axis of rotation of the bearing race, so that the bearing race and the carrier device can rotate at different RPMs. Such a bearing assembly on a rotating carrier is especially well-suited for a centrifuge, in which a separation chamber with a centrally secured line is to be driven in such a way that the tube does not become twisted.Type: GrantFiled: September 8, 1994Date of Patent: September 24, 1996Assignee: Fresenius AGInventors: Friedrich Witthaus, Wolfram Weber, Lothar Leick
