Abstract

A dialysis system is configured to enable a patient to undergo both peritoneal dialysis and extracorporeal blood treatments. The example dialysis system includes a base unit configurable to provide a first fluid for use in preforming at least one peritoneal dialysis treatment at a first time. The base unit is further configurable to provide a second, different fluid for use in at least one extracorporeal blood treatment at a second, different time. The example dialysis system also includes a blood treatment unit configured to be docked to the base unit. The blood treatment unit includes a blood pump configured to pump blood from the patient to a blood filter and from the blood filter back to the patient. The blood filter or a blood line in communication with the blood filter receives the second fluid from the base unit for use in the at least one extracorporeal blood treatment.

First claim

The invention is claimed as follows:

1. In a system enabling both peritoneal dialysis and extracorporeal blood treatments, the system comprising:
a base unit including a base unit controller and a fluid container, the base unit controller programmed to detect whether at least one peritoneal dialysis treatment or at least one extracorporeal blood treatment is to be performed and (i) operate first software instructions when the base unit uses a first fluid stored in the fluid container when the at least one peritoneal dialysis treatment is selected or (ii) operate second software instructions when the base unit uses a second, different fluid from an online source when the at least one extracorporeal blood treatment is selected; and
a blood treatment unit operable with the base unit to perform the at least one extracorporeal blood treatment on a patient, the blood treatment unit including
a blood pump configured to pump blood from the patient and back to the patient,
a controller for controlling the blood pump, and
a user interface for displaying at least one of blood pump settings or blood parameter readings,

wherein the base unit is configured to selectively move the second, different fluid to the blood treatment unit for use in the at least one extracorporeal blood treatment, and
wherein the base unit controller is separate from the controller of the blood treatment unit.

2. The system of claim 1 , wherein the first fluid is a peritoneal dialysis dialysate and the second fluid is an extracorporeal blood treatment dialysate.

3. The system of claim 1 , wherein the second fluid is a replacement fluid.

4. The system of claim 1 , wherein the base unit is configured to prepare dialysis fluid for the at least one extracorporeal blood treatment using the second fluid from the online source.

5. The system of claim 1 , wherein the base unit controller is programmed to know when the blood treatment unit is docked to the base unit.

6. The system of claim 1 , wherein the base unit is configured for use in performing the at least one extracorporeal blood treatment when the blood treatment unit is docketed to the base unit.

7. The system of claim 1 , wherein the base unit controller is programmed to operate with a blood treatment cassette when the blood treatment unit is docked to the base unit.

8. The system of claim 1 , wherein the base unit controller is programmed for extracorporeal blood treatment sensing when the blood treatment unit is docked to the base unit.

9. The system of claim 1 , wherein the base unit controller is programmed to look for blood in a dialysate return line when the blood treatment unit is docked to the base unit.

10. The system of claim 1 , wherein the base unit controller is programmed to monitor sodium in dialysis fluid for the at least one extracorporeal blood treatment when the blood treatment unit is docked to the base unit.

11. The system of claim 1 , wherein the controller of the blood treatment unit is programmed to control at least one of the following: (i) air in blood detection, (ii) operational speed of the blood pump, (iii) blood line priming, (iv) blood rinseback, (v) blood line access disconnection, or (vi) valves associated with a blood treatment disposable.

12. The system of claim 1 , wherein the controller of the blood treatment unit is programmed to control each of the following: (i) air in blood detection, (ii) operational speed of the blood pump, (iii) blood line priming, (iv) blood rinseback, (v) blood line access disconnection, and (vi) valves associated with a blood treatment disposable.

13. The system of claim 1 , wherein the base unit controller is programmed at a first time to perform the at least one peritoneal dialysis treatment on the patient and the blood treatment unit is used at a second time when a renal condition of the patient has worsened, after the first time, to perform the at least one extracorporeal blood treatment on a patient.

14. In a system enabling a patient to undergo both peritoneal dialysis and extracorporeal blood treatments, the system comprising:
a base unit including a base unit controller and a fluid container, the base unit controller programmed to detect whether at least one peritoneal dialysis treatment or at least one extracorporeal blood treatment is to be performed and operate first software instructions when the base unit uses a first fluid stored in the fluid container when the at least one peritoneal dialysis treatment is selected, the base unit controller further programmed to operate second software instructions when the base unit uses a second, different fluid from an online source and move the second fluid when the at least one extracorporeal blood treatment is selected; and
a blood treatment unit configured to be docked to the base unit, the blood treatment unit including a blood pump and a controller configured to pump blood from the patient to a blood filter and from the blood filter back to the patient,
wherein the blood filter or a blood line in communication with the blood filter receives the second fluid from the base unit for use in the at least one extracorporeal blood treatment, and
wherein the base unit controller is separate from the controller of the blood treatment unit.

15. The system of claim 14 , wherein the second fluid includes at least one of a replacement fluid or a dialysis fluid.

16. The system of claim 14 , wherein the first fluid is a peritoneal dialysis fluid and the second fluid is an extracorporeal blood treatment fluid.

17. The system of claim 14 , wherein the first fluid is stored as a premixed fluid.

18. The system of claim 14 , wherein the controller of the blood treatment unit is programmed to perform a handshake routine with the base unit controller for confirming that the blood treatment unit is properly docked to the base unit.

19. The system of claim 14 , wherein the base unit and the blood treatment unit are configured to share data via a wired or wireless connection.

20. The system of claim 14 , which includes a single user interface to control both the base unit and the blood treatment unit.

21. A dialysis system configurable to enable a patient to undergo both a peritoneal dialysis treatment and an extracorporeal blood treatment, the dialysis system comprising:
a peritoneal dialysis unit including
a dialysis fluid pump configured to pump peritoneal dialysis fluid through a patient line to a peritoneal cavity of the patient for a dwell period of the peritoneal dialysis treatment and to remove the peritoneal dialysis fluid from the peritoneal cavity of the patient through the patient line after the dwell period,
a user interface configured to receive user inputs related to the peritoneal dialysis treatment, and
a control unit configured to operate the dialysis fluid pump according to the user inputs to perform the peritoneal dialysis treatment; and

a base unit including a base unit controller and a fluid container, the base unit controller programmed to detect whether the peritoneal dialysis treatment or the extracorporeal blood treatment is to be performed and (i) operate first software instructions when the base unit uses a first fluid stored in a fluid container when the peritoneal dialysis treatment is selected or (ii) operate second software instructions when the base unit uses a second, different fluid from an online source when the extracorporeal blood treatment is selected, the base unit including
a supply fluid line to interchangeably provide the first fluid from
