Abstract: 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.

Abstract: The present application discloses a portable dialysis system for conducting a dialysis treatment. The portable dialysis system has a controller unit that includes a display, a scale, a bar code reader, and a memory storing a plurality of programmatic instructions. Upon execution, the instructions generate a first graphical user interface, a second graphical user interface, and a third graphical user interface for presentation on the display. The first graphical user interface displays each additive required for use in the dialysis treatment. The second graphical user interface prompts a user to submit additives to scanning using the bar code scanner. The third graphical user interface prompts a user to submit additives to measurement using the scale.
