Patent number: 9358331Abstract: 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: December 24, 2012Date of Patent: June 7, 2016Assignee: Fresenius Medical Care Holdings, Inc.Inventors: Barry Neil Fulkerson, Alec Huang, Brian Thomas Kelly, Tam Nolan

Patent number: 9308307Abstract: The specification discloses a portable dialysis machine having a detachable controller unit and base unit. 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 manifold includes diaphragms adapted to minimize the dead space between the dialysis machine pins and improve responsivity. The base unit has a planar surface for receiving a container of fluid, a scale integrated with the planar surface and a heater in thermal communication with the container. Embodiments of the disclosed portable dialysis system have improved structural and functional features, including improved modularity, ease of use, and safety features.Type: GrantFiled: March 28, 2013Date of Patent: April 12, 2016Assignee: Fresenius Medical Care Holdings, Inc.Inventors: Barry Neil Fulkerson, Alec Huang, Brian Thomas Kelly

Publication number: 20160069732Abstract: 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: ApplicationFiled: September 8, 2015Publication date: March 10, 2016Inventors: Barry Neil Fulkerson, Joe Fazio, Alec Huang, Brian Thomas Kelly, Tam Nolan, Mark Smith

Patent number: 8595021Abstract: Methods for using a liner in a waste sorting and disposal system are provided. The liner includes an internal space and an opening that provides access to that internal space. In some embodiments, the liner may also include a machine-readable identification key that is configured to identify a type of waste that the liner may receive. In some embodiments, the machine-readable key is optical, color-coded, alphanumeric or graphical. The liner can include one or more closure members to allow a user to securely seal the liner when it is removed from the container. In some embodiments, the liner can include a flange, lip, hook or other protrusion to secure its position relative to a container.Type: GrantFiled: March 3, 2010Date of Patent: November 26, 2013Assignee: CareFusion 303, Inc.Inventors: Scott R. Mallett, Randall C. Danta, James R. Benson, Alan D. Corey, Alan A. Davidner, Peter Regla, Alec Huang

Publication number: 20020157001Abstract: A computer system, having a portable computer and an expanding apparatus. The portable computer has a display, a first storage apparatus to store a first operating system and an operating system load program, a processing circuit to execute the first operating system for controlling operation of the computer system, and a connector. The expanding apparatus has a second storage apparatus to store a second operating system. When the connector of the portable computer is disconnected with the expanding apparatus, the processing circuit executes the first operating system to allow the portable computer operating independently. When the connector is coupled to the expanding apparatus, the processing circuit uses the operating system load program to load and execute the second operating system, while the first operating system is terminated. In addition, a docking station may also be installed in the expanding apparatus to dispose the portable computer thereon.Type: ApplicationFiled: March 13, 2002Publication date: October 24, 2002Inventors: Alec Huang, Mark Chen
