Abstract

A peritoneal dialysis system includes: a dialysis fluid container associated with an identifier; a reader for reading the identifier; a signal transmitter for communicating data based on the identifier; and a patient transfer set for semi-permanent connection to a patient, the patient transfer set including: (i) a signal receiver for receiving the data sent by the signal transmitter, (ii) an output device for communicating with the patient, and (iii) electronics configured to receive the data and command the output device to communicate with the patient accordingly.

Claims

1. A peritoneal dialysis system comprising:

a dialysis fluid container associated with an identifier;

a reader for reading the identifier;

a signal transmitter for communicating data based on the identifier;

a patient access device; and

a patient transfer set for semi-permanent connection to a patient, the patient transfer set connected directly adjacent to the patient access device and including;

(i) a signal receiver for receiving the data sent by the signal transmitter,

(ii) an output device for communicating with the patient, and

(iii) electronics configured to receive the data and command the output device to communicate with the patient accordingly.

2. The peritoneal dialysis system of claim 1, wherein the reader and the signal transmitter are housed in a common unit.

3. The peritoneal dialysis system of claim 2, wherein the unit further includes a port configured to receive a patient data memory device.

4. The peritoneal dialysis system of claim 2, wherein the unit includes a docking area configured to receive and hold a tube extending from the dialysis fluid container, the reader reading the identifier from the received tube.

5. The peritoneal dialysis system of claim 4, wherein the docking area is configured to receive and hold a connector located at an end of the tube, the reader reading the identifier from the received connector.

6. The peritoneal dialysis system of claim 2, wherein the unit is configured to determine a dwell duration based on the identifier and at least one patient-specific parameter.

7. The peritoneal dialysis system of claim 2, wherein the unit is configured to determine a fill duration based on the identifier and at least one patient-specific parameter.

8. The peritoneal dialysis system of claim 1, wherein the signal transmitter and the signal receiver are configured to communicate the data wirelessly.

9. The peritoneal dialysis system of claim 1, wherein the signal transmitter and the signal receiver are each part of a transceiver for transmitting and receiving the data.

10. The peritoneal dialysis system of claim 1, wherein the identifier identifies at least one of:

(i) a dialysis fluid type, (ii) a dialysis fluid volume, and (iii) dialysis fluid expiration data.

11. The peritoneal dialysis system of claim 1, wherein the data includes a dwell duration, and wherein the patient transfer set includes a start input that the patient activates upon completion of a fill from the dialysis fluid container, the dwell duration initiated upon activation of the start input.

12. The peritoneal dialysis system of claim 11, wherein the output device is configured to alert the patient when the dwell duration has ended or is about to end.

13. The peritoneal dialysis system of claim 1, wherein the data includes (i) a fill duration, after which it is assumed a fill from the dialysis fluid container is completed, and (ii) a dwell duration that begins after the fill duration.

14. The peritoneal dialysis system of claim 13, wherein the output device is configured to alert the patient of at least one of:

(i) the fill duration and (ii) when the dwell duration has ended or is about to end.

15. The peritoneal dialysis system of claim 13, wherein the output device is configured to alert the patient that the fill duration is about to begin.

16. The peritoneal dialysis system of claim 13, which includes a sensor positioned adjacent to the reader, the sensor sensing a presence or an absence of a member bearing identifier, and which is configured to begin a running of the fill duration upon a sensed removal of the member and the identifier from the reader.

17. The peritoneal dialysis system of claim 1, wherein the data includes a solution type, a solution volume and at least one patient-specific parameter, and wherein the electronics are configured to determine at least one of a fill duration, a dwell duration and a start drain time from the data.

18. A peritoneal dialysis system comprising:

a dialysis fluid container associated with an identifier;

a reader for reading the identifier;

a signal transmitter configured to communicate a dwell duration determined at least in part from the identifier;

a patient access device; and

a patient transfer set for semi-permanent connection to a patient, the patient transfer set connected directly adjacent to the patient access device and including;

(i) a signal receiver for receiving the dwell duration sent by the signal transmitter; and

(ii) an output device configured to communicate the dwell duration to the patient.

19. The peritoneal dialysis system of claim 18, wherein the patient transfer set further includes an input device and electronics configured to begin a running of the dwell duration upon the patient activating the input device.

20. The peritoneal dialysis system of claim 18, wherein the identifier identifies at least one of (i) a dialysis fluid type and (ii) a dialysis fluid volume, which are used to determine the dwell duration in combination with at least one patient specific parameter.

21. The peritoneal dialysis system of claim 18, which includes a unit housing the reader and the signal transmitter, the unit further including electronics configured to determine the dwell duration from the identifier.

22. The peritoneal dialysis system of claim 18, wherein the signal transmitter is further configured to communicate a fill duration, after which it is assumed that a fill from the dialysis fluid container is completed, the dwell duration beginning automatically after the fill duration.

23. A peritoneal dialysis system comprising:

a dialysis fluid container associated with an identifier;

a reader for reading the identifier;

a signal transmitter configured to communicate (i) a fill duration, after which it is assumed that a fill from the dialysis fluid container is completed and (ii) a dwell duration based, at least in part, on the identifier;

a sensor positioned to sense a presence of a member bearing the identifier;

a patient access device; and

a patient transfer set for semi-permanent connection to a patient, the patient transfer set connected directly adjacent to the patient access device and including a signal receiver for receiving the fill duration and the dwell duration, the patient transfer set configured to begin a running of the fill duration upon receiving a signal from the transmitter indicating that the sensor sensed a removal of the member from a location of the reader and the sensor.
