Patent number: 11525798Abstract: Methods and systems for monitoring fluid levels and electrolyte levels used in a dialysis machine. A receptacle, configured to receive a container, comprises a plurality of curved side panels and a base to form a cylindrical shaped cavity for receiving a container. Each panel includes a conductive material on its inner surface and, optionally, a shielding on its outer surface. An electronics component housed within, or near, the receptacle drives the capacitive process and interprets generated data to determine fluid levels and compositions. An alternate receptacle includes one or two coils wrapped about the container and uses induction to determine fluid level.Type: GrantFiled: February 27, 2020Date of Patent: December 13, 2022Assignee: Fresenius Medical Care Holdings, Inc.Inventors: Barry Neil Fulkerson, Gregory Hayes Gengarelly, Tam Nolan

Patent number: 11318248Abstract: The specification discloses a portable dialysis machine having a detachable controller unit and base unit with an improved reservoir heating system. The controller unit includes a door having an interior face, a housing with a panel, where the housing and panel define a recessed region configured to receive the interior face of the door, and a manifold receiver fixedly attached to the panel. The base unit has a reservoir with an internal pan and external pan, separated by a space that holds a heating element. The heating element is electrically coupled to electrical contacts attached to the external surface of the external pan.Type: GrantFiled: June 28, 2019Date of Patent: May 3, 2022Assignee: Fresenius Medical Care Holdings, Inc.Inventors: Barry Neil Fulkerson, Alec Huang, Brian Thomas Kelly, Tam Nolan

Patent number: 11187572Abstract: A load suspension and weighing system for a removable reservoir unit of a portable dialysis machine includes a centrally located flexure assembly. The flexure assembly includes magnets and a number of flexure rings which allow for movement of the magnets about a fixed circuit board. Sensors in the circuit board sense changes in the magnetic field as the magnets move in relation to the circuit board. The magnetic field changes produce a voltage output which is used by a processor to generate weight calculations. The top of the flexure assembly is attached to the interior of the dialysis machine. The entirety of the reservoir unit is suspended by a first internal frame that is attached to the bottom of the flexure assembly. Having a single flexure assembly positioned above the reservoir unit provides more accurate weight measurements while also preventing damage to the assembly from water spillage.Type: GrantFiled: December 11, 2019Date of Patent: November 30, 2021Assignee: Fresenius Medical Care Holdings, Inc.Inventors: Barry Neil Fulkerson, Joe Fazio, Alec Huang, Brian Thomas Kelly, Tam Nolan, Mark Smith
