Methods of performing dialysis using an electrodeionization system
View Patent ↗Systems and methods for hemodialysis or peritoneal dialysis having integrated electrodeionization capabilities are provided. In an embodiment, the dialysis system includes a carbon source, a urease source and an electrodeionization unit. The carbon source and urease source can be in the form of removable cartridges.
1. A method of performing peritoneal dialysis comprising:
passing a spent dialysis fluid from an individual through a dialyzer, a carbon source, a urease source and an electrodeionization unit to produce a clean dialysis fluid, the dialyzer comprising an ion-rejection membrane selected from the group consisting of a first ion-rejection membrane that allows the passage of negatively charged ions and non-ionic species but restricts the passage of positively charged ions, and a second ion-rejection membrane that allows the passage of positively charged ions and non-ionic species but restricts the passage of negatively charged ions; and
returning the clean dialysis fluid to the individual.
2. The method of claim 1 , which includes passing the clean dialysis fluid through an ion exchange unit before the clean dialysis fluid returns to the patient.
3. The method of claim 1 , which includes adding at least one dialysis component to the clean dialysis fluid before the clean dialysis fluid returns to the individual.
4. The method of claim 1 , which includes passing the clean dialysis fluid through a filter before the clean dialysis fluid returns to the patient.
5. The method of claim 1 , which includes passing the clean dialysis fluid through an ultraviolet bactericidal light before the clean dialysis fluid returns to the patient.
6. A method of performing dialysis comprising:
passing a spent dialysis fluid through a dialysis compartment of a dialyzer comprising an ion-rejection membrane that allows the passage of negatively charged ions and non-ionic species but restricts the passage of positively charged ions, the ion-rejection membrane separating the dialysis compartment from a dialysate compartment of the dialyzer;
passing used dialysis fluid generated from the dialysate compartment of the dialyzer through a carbon source, a urease source and an electrodeionization unit to produce a clean dialysis fluid;
adding a source of negative ions to the clean dialysis fluid; and
passing the clean dialysis fluid through the dialysate compartment of the dialyzer.

passing used dialysis fluid generated from the dialysate compartment of the dialyzer through a carbon source, a urease source and an electrodeionization unit to produce a clean dialysis fluid;
adding a source of positive ions to the clean dialysis fluid; and
passing the clean dialysis fluid through the dialysate compartment of the dialyzer.
