Abstract

A peritoneal dialysis machine includes an enclosure; dialysate pump located within the enclosure; a graphical user interface allowing a patient to program a treatment including at least one patient fill performed by the dialysate pump, at least one dwell, and at least one drain performed by the dialysate pump; and the GUI further programmed to provide an alert when it is time to begin the treatment so as to complete the at least one patient fill, dwell and drain by a prescribed time.

Claims

1. A dialysis machine comprising:

a dialysate pump; and

a graphical user interface (“

GUI”

) allowing a patient to;

(a) program a treatment including at least one patient fill performed by the dialysate pump, at least one dwell, and at least one patient drain performed by the dialysate pump, and

(b) enter a treatment completion time of day, wherein

the GUI is further programmed to;

calculate a treatment start time based on the programmed treatment and the treatment completion time, and provide an alert when it is time to begin the treatment so as to complete the at least one patient fill, dwell and drain by the treatment completion time.

2. The dialysis machine of claim 1, the alert a tactile, audio, visual or audio-visual alert.

3. The dialysis machine of claim 1, wherein a time of the at least one patient fill and a time of the at least one patient drain is preset or calculated based on dialysate pump rate and fill or drain volume.

4. The dialysis machine of claim 1, the GUI alert providing for an amount of time to set up the treatment.

5. The dialysis machine of claim 1, which includes a remote device configured to operate with the GUI, the remote device allowing the patient to program the treatment remotely.

6. The dialysis machine of claim 5, wherein the remote device communicates with the GUI via wired or wireless communication.

7. The dialysis machine of claim 6, wherein the wireless communication uses a wireless communication technology selected from the group consisting of:

(a) WiFi;

(b) Bluetooth;

(c) Zigbee; and

(d) infrared.

8. The dialysis machine of claim 1, which includes a remote patient alert device configured to operate with the GUI to provide a remote alert to the patient when it is time to begin the treatment.

9. The dialysis machine of claim 8, wherein the remote alert provided to the patient is set via a wireless data link.

10. The dialysis machine of claim 9, wherein the remote alert provided to the patient is sent to a cellular phone or pager associated with the patient.

11. The dialysis machine of claim 1, wherein the calculation is performed by a processor operable with the GUI.

12. The dialysis machine of claim 11, wherein the total treatment duration is calculated based upon at least one of a plurality of treatment parameters selected from the group consisting of:

(i) a therapy setup duration;

(ii) a therapy cycle count;

(iii) a patient dwell duration of the at least one patient dwell;

(iv) a minimum patient dwell duration;

(v) a patient fill duration of the at least one patient fill;

(vi) a patient drain duration of the at least one patient drain; and

(vii) an actual therapy start time when the patient actually begins the treatment.

13. The dialysis machine of claim 12, wherein for each therapy cycle count, the at least one patient dwell duration can be adjusted based upon at least one of the treatment parameters selected from the group consisting of:

(i) the patient fill duration;

(ii) the patient drain duration; and

(iii) the actual therapy start time.

14. The dialysis machine of claim 13, wherein the processor is configured to alarm if the at least one patient dwell duration is adjusted to a duration less than the minimum patient dwell duration.

15. The dialysis machine of claim 12, wherein the therapy setup duration includes an estimated patient hook-up duration and an estimated patient disconnection duration.

16. The dialysis machine of claim 12, wherein each therapy cycle count includes at least two of:

(A) one of the patient dwells;

(B) one of the patient fills;

or (C) one of the patient drains.

17. A dialysis machine comprising:

a dialysate pump; and

a graphical user interface (“

GUI”

) allowing a patient to;

(a) program a treatment including at least one patient fill performed by the dialysate pump, at least one patient dwell, and at least one patient drain performed by the dialysate pump, and

(b) enter a treatment completion time of day, wherein

the GUI is further programmed to adjust a duration of the at least one patient dwell automatically so as to be able to complete the at least one patient fill, the at least one patient dwell and the at least one patient drain by the treatment completion time.

18. The dialysis machine of claim 17, which includes a processor operable with the GUI to calculate a total treatment duration based upon the treatment programmed by the patient and use the total treatment duration to calculate the time to begin the treatment.

19. The dialysis machine of claim 17, which includes a remote device configured to operate with the GUI, allowing the patient to program the treatment remotely.

20. The dialysis machine of claim 19, the remote device communicating with the GUI via wired or wireless communication.

21. The dialysis machine of claim 20, wherein the wireless communication uses wireless communication technology selected from the group consisting of:

(a) WiFi;

(b) Bluetooth;

(c) Zigbee; and

(d) infrared.

22. The dialysis machine of claim 18, wherein the total treatment duration is calculated based upon a plurality of treatment parameters selected from the group consisting of:

(i) a therapy setup duration;

(ii) a therapy cycle count;

(iii) the patient dwell duration;

(iv) a minimum patient dwell duration;

(v) a patient fill duration of the at least one patient fill;

(vi) a patient drain duration of the at least one patient drain; and

(vii) an actual therapy start time when the patient begins the therapy.

23. The dialysis machine of claim 22, wherein the at least one patient dwell duration can be adjusted based upon at least one of the treatment parameters selected from the group consisting of:

(i) the patient fill duration;

(ii) the patient drain duration; and

(iii) the actual therapy start time.

24. The dialysis machine of claim 23, wherein the processor is configured to alarm if the at least one patient dwell duration is adjusted to a duration less than the minimum patient dwell duration.

25. The dialysis machine of claim 22, wherein the therapy setup duration includes an estimated patient hook-up duration and an estimated patient disconnection duration.

26. The dialysis machine of claim 22, wherein each therapy cycle count includes at least two of:

(A) one of the patient dwells;

(B) one of the one patient fills;

or (C) one of the patient drains.

27. The dialysis machine of claim 22, wherein the patient fill duration and the patient drain duration are preset or calculated based upon a dialysate pump rate of the dialysate pump and a fill volume or a drain volume, respectively.
