Abstract: The invention relates to infusate containers and related systems and methods for housing infusates that can be added to a fluid flow path for use during dialysis. The infusate containers can include a filter partitioning the containers into a first and second compartment, a draw tube for drawing up fluid from a bottom portion, a cap, a fluid connector for delivery and withdrawal of fluid from the two compartments, and a fluid connector for connection to a dialysis system.

Abstract: A system for measuring at least one fluid characteristic at various stages within a sorbent system that has a sorbent cartridge that has at least one material layer and at least one fluid passageway in at least one location in the sorbent system to provide a diverted sample stream from the various stages. At least one fluid characteristic of the diverted sample stream is measured.

Abstract: The invention relates to fluid flow paths and fluid connectors for use with detachable containers that can be seated in an infusate caddy for use in a dialysis machine. The detachable containers can contain infusates or other solutes or materials such as disinfectants or cleaners, and can be conveniently seated in the infusate caddy. The detachable containers can be removed from the infusate caddy for restocking, cleaning, or resupply, as needed. The infusate caddy can be positioned or seated in a receiving compartment of a dialysis machine, and can also be removed, as needed. The fluid path and fluid connectors of the present invention provide the required fluid fittings, valve arrangements, pumps, and paddle assemblies for using the infusate caddy.

Abstract: A blood based solute monitoring system for measuring at least one blood solute species that has a first recirculation flow path in communication with a dialyzer. The first recirculation flow path is configured to allow a fluid to recirculate through a dialyzer such that the concentration of at least one solute species in the fluid becomes equilibrated to the solute species concentration of the blood compartment of the dialyzer. The blood solute monitoring system has at least one sensor to measure a fluid characteristic.

Abstract: Apparatuses, systems, and methods for the performance of kidney replacement therapy having or using a dialyzer, control components, sorbent cartridge, and fluid reservoirs configured to be of a weight and size suitable to be worn or carried by an individual requiring treatment are disclosed. The system has a controlled compliance dialysis circuit, where a control pump controls the bi-directional movement of fluid across a dialysis membrane. A first sorbent cartridge is provided for use in a portable treatment module having activated carbon and zirconium oxide. The system also provides for the monitoring of an inlet and outlet conductivity of a sorbent cartridge containing urease to provide a facility to quantify or monitor the removal of urea by a detachable urea removal module.

Abstract: Systems and methods for managing the sodium concentration of a dialysate fluid during hemodialysis therapy and adjusting sodium concentration using a sodium management system to generate a sodium-modified fluid are provided. The systems and methods also provide a mechanism for controlled addition of sodium ions to the dialysate to generate a predetermined total sodium concentration in a dialysate.

Abstract: Systems and methods for the performance of kidney replacement therapy having or using a dialyzer, control components, sorbent cartridge and fluid reservoirs configured to be of a weight and size suitable to be worn or carried by an individual requiring treatment are disclosed. The system for performing kidney replacement therapy has a controlled compliance dialysis circuit, where a control pump controls the bi-directional movement of fluid across a dialysis membrane. The dialysis circuit and an extracorporeal circuit for circulating blood are in fluid communication through the dialysis membrane. The flux of fluid moving between the extracorporeal circuit and the dialysis circuit is modified by the rate at which the control pump is operating such that a rate of ultrafiltration and convective clearance can be controlled. The system provides for the monitoring of an inlet and outlet conductivity of the sorbent cartridge to provide a facility to quantify or monitor the removal of urea by the sorbent cartridge.
