Abstract

A peritoneal dialysis system includes a base peritoneal dialysis system and a peritoneal dialysis fluid exchange system that operates independently of the base system. The base system includes a first cassette including a first patient line configured to be connected to a patient, and a PD cycler. The PD cycler receives the first cassette, and includes a pump that cooperates with the first cassette to deliver dialysate to and drain dialysate from a peritoneal cavity of the patient via the first patient line. The peritoneal dialysis fluid exchange system includes a second cassette including a second patient line configured to be connected to the patient and a fluid exchange device that receives the second cassette. The fluid exchange device includes a data exchange interface operable to transfer patient treatment data from the peritoneal dialysis fluid exchange system to the base peritoneal dialysis system.

First claim

What is claimed is:

1. A method of providing dialysis treatment comprising:
obtaining patient treatment data during peritoneal dialysis performed on a patient by a first peritoneal dialysis system that includes a gravity feed cassette and a fluid exchange device that releasably receives the gravity feed cassette, wherein the fluid exchange device has a small size and light weight that allows the fluid exchange device to be held in a single hand of the patient, wherein the peritoneal dialysis is performed on the patient using gravity force to drive: (i) infusion of dialysis solution into the patient through the gravity feed cassette from a source of the dialysis solution positioned higher than the patient and (ii) drainage of fluid from the patient through the gravity feed cassette to a location positioned lower than the patient, and wherein the peritoneal dialysis performed on the patient includes actuating valve members of the fluid exchange device to control flow of the dialysis solution through the gravity feed cassette,
transferring the obtained patient treatment data from the first peritoneal dialysis system to a second peritoneal dialysis system, and
determining, by the second peritoneal dialysis system, a modified patient treatment plan for treating the patient using the second peritoneal dialysis system, wherein the modified patient treatment plan is determined based on the obtained patient treatment data transferred from the first peritoneal dialysis system.

2. The method of claim 1 , wherein the first peritoneal dialysis system has a size and weight that is less than a size and weight of the second peritoneal dialysis system.

3. The method of claim 1 , further comprising:
performing a second peritoneal dialysis treatment of the patient using the second peritoneal dialysis system and the modified patient treatment plan.

4. The method of claim 1 , wherein obtaining the patient treatment data includes measuring fluid flow rates through the first peritoneal dialysis system and measuring fluid flow durations through the first peritoneal dialysis system.

5. The method of claim 1 , wherein obtaining the patient treatment data includes measuring fluid flow rates through the first peritoneal dialysis system and measuring fluid flow durations through the first peritoneal dialysis system, and using the measured fluid flow rates and the measured fluid flow durations to determine at least one of a volume of fluid infused to the patient and a volume of fluid drained from the patient.

6. The method of claim 5 , wherein determining the modified patient treatment plan includes adjusting at least one of an infusing volume and a draining volume in the dialysis treatment based on the volume of fluid infused to the patient and the volume of fluid drained from the patient using the first peritoneal dialysis system.

7. The method of claim 1 , wherein transferring the obtained patient treatment data is achieved via a wireless connection between the first peritoneal dialysis system and the second peritoneal dialysis system.

8. The method of claim 7 , wherein transferring the obtained patient treatment data begins during the peritoneal dialysis performed by the first peritoneal dialysis system.

9. The method of claim 1 , wherein transferring the obtained patient treatment data is achieved via a wired connection between the first peritoneal dialysis system and the second peritoneal dialysis system.

10. The method of claim 1 , further comprising alerting a user based on the obtained patient treatment data.

11. The method of claim 1 , wherein determining the modified patient treatment plan comprises synchronizing the obtained patient treatment data with a previously-stored patient treatment plan.

12. The method of claim 1 , wherein the fluid exchange device weighs less than one pound.

13. A method of providing dialysis treatment comprising:
obtaining patient treatment data during peritoneal dialysis performed on a patient by a first peritoneal dialysis system that includes a cassette and a fluid exchange device that releasably receives the cassette, wherein the fluid exchange device has a small size and light weight that allows the fluid exchange device to be held in a single hand of the patient, wherein the peritoneal dialysis performed on the patient includes actuating valve members of the fluid exchange device to control flow of dialysis solution through the cassette,
transferring the obtained patient treatment data from the first peritoneal dialysis system to a second peritoneal dialysis system, and
determining, by the second peritoneal dialysis system, a modified patient treatment plan for treating the patient using the second peritoneal dialysis system, wherein the modified patient treatment plan is determined based on the obtained patient treatment data transferred from the first peritoneal dialysis system.

14. The method of claim 13 , wherein the fluid exchange device weighs less than one pound.

15. The method of claim 13 , wherein obtaining the patient treatment data includes measuring fluid flow rates through the first peritoneal dialysis system and measuring fluid flow durations through the first peritoneal dialysis system, and using the measured fluid flow rates and the measured fluid flow durations to determine at least one of a volume of fluid infused to the patient and a volume of fluid drained from the patient.

16. The method of claim 15 , wherein determining the modified patient treatment plan includes adjusting at least one of an infusing volume and a draining volume in the dialysis treatment based on the volume of fluid infused to the patient and the volume of fluid drained from the patient using the first peritoneal dialysis system.

17. The method of claim 13 , wherein transferring the obtained patient treatment data is achieved via a wireless connection between the first peritoneal dialysis system and the second peritoneal dialysis system.

18. The method of claim 17 , wherein transferring the obtained patient treatment data begins during the peritoneal dialysis performed by the first peritoneal dialysis system.
