Abstract: Techniques for modeling therapy fields for therapy delivered by medical devices are described. Each therapy field model is based on a set of therapy parameters and represents where therapy will propagate from the therapy system delivering therapy according to the set of therapy parameters. Therapy field models may be useful in guiding the modification of therapy parameters. As one example, a processor compares an algorithmic model of a therapy field to a reference therapy field and adjusts at least one therapy parameter based on the comparison. As another example, a processor adjusts at least one therapy parameter to increase an operating efficiency of the therapy system while substantially maintaining the modeled therapy field.

Abstract: The invention relates to a testing system and related methods for detecting peritonitis or infection in peritoneal dialysate removed from a patient. The testing system can include a fluid sensor apparatus in a fluid line of a peritoneal dialysis cycler through which spent peritoneal dialysate can be pumped. The fluid sensor apparatus can detect one or more markers associated with peritonitis or infection.

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: A stacked sorbent assembly for use in sorbent dialysis. The stacked sorbent assembly contains two or more interchangeable sorbent pouches that allow for fluid to freely pass into and through the sorbent materials, while keeping the sorbent materials inside the sorbent pouches. Any of the pouches in the sorbent cartridge can be reused and/or recharged.

Abstract: The invention relates to systems and methods for sensing fluid characteristics of peritoneal dialysate infused into and removed from a patient during treatment. The systems and methods include sensors, processors, and flow paths for determining patient health based on the fluid characteristics of the peritoneal dialysate. The system can be a peritoneal dialysis cycler which can include an infusion line; an effluent line; at least one pump positioned in the infusion and/or effluent line; and at least one sensor fluidly connected to the effluent line. The sensor can be at least one of a flow sensor, an ion selective electrode, a pH sensor, a pressure sensor, a refractive index sensor, and a temperature sensor. The method can include infusing peritoneal dialysate through an infusion line; removing peritoneal dialysate through an effluent line; and determining at least one fluid characteristic of the peritoneal dialysate in the effluent line.

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.
