A flexible tube routing accessory for routing a flexible tube between a preparator and an automatic cycler of a peritoneal dialysis system, the flexible tube routing accessory comprising: a guide pipe through which the flexible tube is to be routed; a guide wire configured to pass through the guide pipe and selectively connect to the flexible tube; and a winding mechanism configured to move the guide wire through the guide pipe.

Flexible tube routing accessory for peritoneal dialysis system

The invention relates to devices, systems, and methods for generating a peritoneal dialysate having specified concentrations of one or more solutes. The devices, systems and methods use conductivity sensors, flow meters, and composition sensors to control addition of osmotic agents and ion concentrates into a peritoneal dialysate generation flow path.

Peritoneal dialysate preparation and sensor system

System and methods for sensing fluid characteristics of peritoneal dialysate infused into and removed from a patient during treatment are provided. The systems and methods can use an optical sensor including a transmitter light source operable to emit light through a fluid flow path and an optical receiver operable to receive at least a portion of the light emitted by the transmitter light source.

Dextrose concentration sensor for a peritoneal dialysis system

The invention relates to systems and methods for generation and use of peritoneal dialysis fluid. The peritoneal dialysis fluid is generated by dissolving solids or diluting concentrated liquids in a single container having all components of the final peritoneal dialysis fluid.

Single container preparation of peritoneal dialysis fluid

The invention relates to devices, systems, and methods for preforming a precision dialysis therapy session based on an analysis of an effluent from a zirconium phosphate sorbent module during an ammonium removal process. The settings for the precision dialysis therapy session can be obtained by estimating a patient's physiological state, such as BUN level, based on the analysis of the effluent for a particular sorbent module linked to a particular patient.

Precision dialysis therapy based on sorbent effluent analysis

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.

Peritoneal dialysate flow path sensing

The invention relates to systems and methods for making intracycle adjustments to an osmotic agent concentration of peritoneal dialysate inside the peritoneal cavity of a patient. The systems and methods include osmotic agent sources, flow paths, and processors to adjust the osmotic agent concentration of dialysate in the peritoneal cavity of the patient. The method can include infusing peritoneal dialysate containing an osmotic agent into the peritoneal cavity of a patient; monitoring one or more patient parameters; and adjusting the osmotic agent concentration of the peritoneal dialysate in the peritoneal cavity of the patient by infusing a concentrated osmotic agent solution or by infusing sterile fluid into the peritoneal cavity of the patient using an on-line peritoneal dialysis machine. The system can include a peritoneal dialysis cycler.

Peritoneal dialysis intracycle osmotic agent adjustment

The invention relates to systems and methods for disinfecting, recharging, and conditioning zirconium phosphate in a reusable sorbent module. The systems and methods provide for reuse of a zirconium phosphate sorbent module after dialysis.

Zirconium phosphate disinfection recharging and conditioning

The invention relates to devices, systems, and methods for measuring dialysis adequacy in patients undergoing peritoneal dialysis treatment. The devices, systems, and methods use one or more flow sensors and one or more solute sensors to measure the concentration of a uremic solute and volume of the peritoneal dialysate removed from the patient, and to calculate the dialysis adequacy based on the measured peritoneal dialysate concentration and volume.

Peritoneal dialysis adequacy meaurements

The invention relates to devices, systems, and methods for performing a precision or personalized Peritoneal Dialysis (PD) therapy session or cycle based on dialysis adequacy measurements in patients undergoing peritoneal dialysis treatment. The settings for the precision peritoneal dialysis therapy session can be obtained using one or more flow sensors and one or more uremic solute sensors that measure the uremic solute concentration and volume of the peritoneal dialysate removed from the patient. The desired dialysis adequacy for a specific patient, group of patients, or class of patients, can then be calculated based on the measured peritoneal dialysate concentration and volume. Using the calculated dialysis adequacy, the system and methods can then set one or more peritoneal dialysis parameters for subsequent cycles or sessions.

Precision peritoneal dialysis therapy based on dialysis adequacy measurements

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.

Peritoneal dialysis fluid testing system

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.

Stacked sorbent assembly

The invention relates to devices, systems, and methods for conditioning a zirconium oxide sorbent module for use in dialysis after recharging. The devices, systems, and methods can provide for conditioning and recharging of zirconium oxide in a single system, or in separate systems.

Zirconium oxide module conditioning

The invention relates to devices, systems, and methods for precision recharging of sorbent materials in a sorbent module. The devices, systems, and methods use manufacturing characteristics of the sorbent module to set recharge parameters used in recharging the sorbent material.
