Abstract

A peritoneal dialysis machine including a membrane pump and a touch screen display that includes a mode-indicating portion and an operation-descriptive portion, the mode-indicating portion having a plurality of touch sensitive indicia each indicating one of a plurality of modes in which the machine can operate, the display being used to keep a patient continually informed of which one mode of at least three operating modes the machine is operating in, as the operation-descriptive portion changes to display details of a specific operation being carried out within the one mode, the indicia for each of the three operating modes always being visible to the patient while the machine is operating, the operating mode being selected by the patient touching one of the indicia on the screen.

Claims

1. A peritoneal dialysis method for operating a peritoneal dialysis system, the system including

a stepper motor housed by an enclosure,

a pump head in operable communication with the stepper motor,

a disposable unit including at least one flexible membrane attached to a rigid piece, the enclosure configured to receive the disposable unit such that the stepper motor can move the pump head towards and away from the flexible membrane, and

a graphical user interface including a display device, the method comprising:

displaying a plurality of peritoneal dialysis (“

PD”

) screens on the display device, a first area of the display device dedicated to a plurality of mode selection icons, each mode icon dedicated to a single mode, the area and the mode selection icons displayed on each of the peritoneal dialysis screens;

temporarily displaying on a second area of the display device, for each selected mode icon, at least one of a graphic and text specific to a selected corresponding mode, the modes including a therapy mode, a parameter adjustment mode and a log mode; and

causing, upon selection of one of the modes, the display device to operate in the selected mode, the therapy mode including a graphic pictorially discerning between a PD fill cycle and a PD drain cycle and pictorially indicating how far the fill or drain cycle has proceeded.

2. The peritoneal dialysis method of claim 1, which includes maintaining a home position to indicate a fully opened or fully closed position for the membrane with respect to the rigid piece of the disposable unit.

3. The peritoneal dialysis method of claim 2, which includes moving the stepper motor automatically upon power-up until the home position is sensed.

4. The peritoneal dialysis method of claim 1, which includes enabling the graphical user interface to indicate that a peritoneal dialysis therapy step displayed by one of the peritoneal dialysis screens has been completed.

5. The peritoneal dialysis method of claim 1, which includes enabling the graphical user interface to stop a peritoneal dialysis step corresponding to one of the peritoneal dialysis screens.

6. The peritoneal dialysis method of claim 1, which includes enabling the graphical user interface to cause a display of a previously displayed one of the peritoneal dialysis screens.

7. The peritoneal dialysis method of claim 1, which includes enabling the graphical user interface to control the display of one of a plurality of different sets of screens, the sets categorizing the screens according to functionality, the sets each corresponding to one of the mode selection icons.

8. The peritoneal dialysis method of claim 1, wherein the sets of screens include a therapy set, a parameter adjustment set and a log set.

9. The peritoneal dialysis method of claim 1, wherein the graphical user interface includes an analog input device that operates with the processor so that at least one operating dialysis parameter on one of the peritoneal dialysis screens is displayed, which is not initially displayed by the peritoneal dialysis screens.

10. The peritoneal dialysis method of claim 1, which includes bordering the second area.

11. The peritoneal dialysis method of claim 1, which includes enabling the mode selection icons to each be touch selectable.

12. The peritoneal dialysis method of claim 1, which includes enabling the graphical user interface to indicate the mode selection icon that corresponds to a currently active mode.

13. The peritoneal dialysis method of claim 1, which includes causing a plurality of therapy set-up screens in the therapy mode have a first coloration and a plurality of therapy treatment screens in the therapy mode have a second coloration.

14. The peritoneal dialysis method of claim 1, which includes enabling a user to actively proceed through a plurality of therapies set-up screens and providing a plurality of dialysis treatment screens that do not require an input by the user to proceed through treatment.

15. The peritoneal dialysis method of claim 1, which includes dividing at least one of the modes corresponding to at least one of the mode selection icons into a plurality of selectable sub-categories.

16. A method for operating a peritoneal dialysis machine, the machine including a touch screen display that includes a mode-indicating portion and an operation-descriptive portion, the mode-indicating portion having a plurality of touch sensitive indicia each indicating one of a plurality of modes in which the machine can operate, the display being used to keep a patient continually informed of which one mode of at least three operating modes the machine is operating in, as the operation-descriptive portion changes to display details of a specific operation being carried out within the one mode, the indicia for each of the three operating modes always being visible to the patient while the machine is operating, the operating mode being selected by the patient touching one of the indicia on the screen, the method including:

(i) touching one of the indicia to select a current operating mode in which the machine is operating, the indicia for the selected mode being highlighted in response to that mode being selected;

(ii) displaying, in the operation descriptive portion of the display, information is concerning the operation of the machine within the selected operating mode without changing either the display of the indicia for each of the three operating modes or changing the highlighting of the indicia for the selected mode; and

(iii) selecting a different indicia to change the mode of operation of the machine, which causes a different indicia to be highlighted and at the same time, causes the previously selected indicia for the prior mode of operation to be unhighlighted.

17. The peritoneal dialysis method of claim 16, which includes displaying on the touch screen display the mode-indicating portion above the operation description portion.

18. The peritoneal dialysis method of claim 16, which includes enabling a membrane pump to be programmed for operation using one of the modes.

19. The peritoneal dialysis method of claim 18, which includes setting, in the pump programming mode, a number pneumatic and mechanical actuations of a membrane of the pump that is needed to pump a desired amount of dialysis fluid to the patient.

20. The peritoneal dialysis method of claim 18, which includes setting, in the pump programming mode, a number pneumatic and mechanical actuations of a membrane of the pump that is needed to pump a desired amount of dialysis fluid from the patient.

21. The peritoneal dialysis method of claim 18, which includes setting, in the pump programming mode, an amount of time that a membrane of the pump is idle during a dwell phase.

22. The peritoneal dialysis method of claim 18, which includes displaying a status of the membrane pump in an ongoing therapy mode.

23. The peritoneal dialysis method of claim 16, which includes setting the plurality of modes in which the machine can operate to include a therapy setting made, an ongoing therapy mode and a therapy logs mode.

24. The peritoneal dialysis method of claim 16, which includes electronically isolating the touch screen display from all electrically alive components of the machine.

25. The peritoneal dialysis method of claim 24, wherein the electronic isolation includes allowing an ungrounded remote power supply to power the machine.

26. The peritoneal dialysis method of claim 16, which includes displaying only the three modes to the patient.
