Abstract
Systems and methods of generating peritoneal dialysate are provided. The systems and methods use a water purification module, a sterilization module and concentrates to prepare a bolus of peritoneal dialysate from source water for use with a non-integrated cycler. The systems and methods use at least two concentrate sources to generate a peritoneal dialysate.
Claims20
A system, comprising:
- a peritoneal dialysate generation cabinet, the peritoneal dialysate generation cabinet configured to house:
- a peritoneal dialysate generation flow path, wherein the peritoneal dialysate generation flow path is configured to receive water from a water source, the water source fluidly connectable to an inlet of the peritoneal dialysate generation flow path, wherein the peritoneal dialysate generation flow path comprises:
- one or more water purification modules fluidly connectable to the peritoneal dialysate generation flow path downstream of the water source, the one or more water purification modules configured to purify the water from the water source and output a purified water downstream to a first conduit;
- at least two concentrate sources fluidly connectable to the first conduit of the peritoneal dialysate generation flow path through a first concentrate line, wherein the at least two concentrate sources each contain one or more solutes, wherein the at least two concentrate sources comprise at least one osmotic agent;
- at least one valve positioned in the first concentrate line, wherein the at least one valve is configured to fluidly connect the first concentrate line to the first conduit to add a concentrate from each of the at least two concentrate sources to the purified water in the first conduit;
- one or more pumps positioned in the first concentrate line, the one or more pumps configured to add the concentrate from the at least two concentrate sources to the purified water in the first conduit to generate peritoneal dialysate;
- a sterilization module fluidly connectable to the first conduit downstream of the at least two concentrate sources and the one or more water purification modules;
- wherein the first conduit fluidly connects the one or more water purification modules to the sterilization module;
- wherein the first concentrate line is fluidly connected to the first conduit between the one or more water purification modules and the sterilization module;
- and
- a control system, the control system programmed to add the at least one osmotic agent to the purified water in the first conduit, and the control system configured to determine a concentration of the at least one osmotic agent in the peritoneal dialysate in the first conduit, and the control system configured to adjust the one or more pumps to maintain a predetermined concentration of the at least one osmotic agent in the peritoneal dialysate in the first conduit based upon the determined concentration;
- and
- at least one storage container;
- wherein the at least one storage container is configured to be:
- fluidly connectable to and fluidly disconnectable from an outlet of the peritoneal dialysate generation cabinet;
- fluidly connectable to and fluidly disconnectable from a non-integrated cycler for conducting a peritoneal dialysis therapy,
- wherein the non-integrated cycler is an external cycler which is not located within the peritoneal dialysate generation cabinet;
- wherein, when the at least one storage container is connected to the peritoneal dialysate generation flow path of the peritoneal dialysate generation cabinet, the at least one storage container is located outside the peritoneal dialysate generation cabinet;
- at least one valve configured to connect to the at least one storage container configured to selectively direct fluid to a desired container of the at least one storage container,
- wherein the system is configured to control the at least one valve to direct the fluid to the desired container based on the predetermined concentration of the at least one osmotic agent in the peritoneal dialysate and to direct the fluid to a second desired container based on a second predetermined concentration of the at least one osmotic agent in the peritoneal dialysate,
- wherein the predetermined concentration of the at least one osmotic agent is different than the second predetermined concentration of the at least one osmotic agent in the peritoneal dialysate.

A system comprising:
- a peritoneal dialysate generation cabinet,
- wherein the peritoneal dialysate generation cabinet is configured to house at least:
- a water purification module;
- a concentrate source;
- and
- a sterilization module;
- wherein the water purification module, the concentrate source, and the sterilization module are fluidly connectable to each other by a fluid flow path;
- and
- at least one storage container,
- wherein the at least one storage container is fluidly connectable to an outlet of the fluid flow path of the peritoneal dialysate generation cabinet;
- wherein, when the at least one storage container receives a sterilized peritoneal dialysate from the peritoneal dialysate generation cabinet, the at least one storage container is configured to be:
- fluidly disconnected from the outlet of the fluid flow path of the peritoneal dialysate generation cabinet;
- and
- fluidly connected to a cycler for conducting a peritoneal dialysis therapy,
- wherein the cycler is an external cycler which is not integrated with the fluid flow path of the peritoneal dialysate generation cabinet;
- at least one valve configured to connect to the at least one storage container configured to selectively direct fluid to a desired container of the at least one storage container,
- wherein the system is configured to control the at least one valve to direct the fluid to the desired container based on a predetermined concentration of at least one osmotic agent in the peritoneal dialysate and to direct the fluid to a second desired container based on a second predetermined concentration of the at least one osmotic agent in the peritoneal dialysate,
- wherein the predetermined concentration of the at least one osmotic agent is different than the second predetermined concentration of the at least one osmotic agent in the peritoneal dialysate.
