Abstract

This invention relates to a device for peritoneal dialysis with a means for the regular discharge and reuptake of dialysate, wherein the means includes an agent by which the color and turbidity of the dialysate can be determined.

Claims

1-14. -14. (canceled)

15. A peritoneal dialysis device, comprising:

a display, wherein the peritoneal dialysis device is configured to display a plurality of colors on the display in a manner such that a user of the peritoneal dialysis device can select the displayed color that most closely corresponds to a color of used dialysate exiting the peritoneal dialysis device.

16. The device of claim 15, wherein the peritoneal dialysis device is configured to individually display the colors.

17. The device of claim 15, wherein the peritoneal dialysis device is configured to display the plurality of colors as a color spectrum in a manner such that the user of the peritoneal dialysis device can select the displayed color that most closely corresponds to the color of the used dialysate exiting the peritoneal dialysis device.

18. The device of claim 15, wherein the peritoneal dialysis device is configured to store the color selected by the user.

19. The device of claim 18, wherein the peritoneal dialysis device comprises memory for storing the color selected by the user.

20. The device of claim 18, wherein the peritoneal dialysis device comprises a removable storage medium on which the color selected by the user is stored together with alphanumeric data.

21. The device of claim 20, wherein the removable storage medium comprises a memory chip, and the alphanumeric data comprises patient data.

22. The device of claim 15, wherein the display is in the form of a touch screen.

23. The device of claim 15, wherein the plurality of colors are displayed in a designated window on the display.

24. The device of claim 15, wherein the display comprises an illumination field configured to illuminate the used dialysate in a conduit.

25. The device of claim 15, wherein the peritoneal dialysis device is configured to emit an alarm when the color selected by the user differs from a theoretical color by a certain degree.

26. The device of claim 25, wherein the alarm is a visual alarm displayed in an alarm field of the display.

27. The device of claim 15, wherein, in addition to the plurality of colors on the display that the user of the peritoneal dialysis device can select, the peritoneal dialysis device is configured to display on the display a plurality of colors previously selected by a user of the peritoneal dialysis device.

28. The device of claim 15, wherein the peritoneal dialysis device is configured to display a plurality of turbidity levels on the display in a manner such that a user of the peritoneal dialysis device can select the displayed turbidity level that most closely corresponds to a turbidity of the used dialysate exiting the peritoneal dialysis device.

29. The device of claim 28, wherein the peritoneal dialysis device is configured to display the plurality of turbidity levels as a turbidity level spectrum in a manner such that the user of the peritoneal dialysis device can select the displayed turbidity level that most closely corresponds to the turbidity of the used dialysate exiting the peritoneal dialysis device.

30. A peritoneal dialysis method, comprising:

selecting a color displayed on a display of a peritoneal dialysis device that most closely corresponds to a color of used dialysate exiting the peritoneal dialysis device; and

storing the selected color in the peritoneal dialysis device.

31. The method of claim 30, wherein the selected color is stored in memory of the peritoneal dialysis device.

32. The method of claim 30, wherein the selected color is stored on a removable storage medium of the peritoneal dialysis device.

33. The method of claim 30, wherein the selected color is stored together with alphanumeric values.

34. The method of claim 33, wherein the alphanumeric values comprise patient data.

35. The method of claim 30, further comprising displaying a color spectrum on the display, wherein the selected color is one of multiple colors on the color spectrum.

36. The method of claim 30, further comprising illuminating the used dialysate in a conduit in order to allow the user to select the displayed color that most closely corresponds to the color of the used dialysate.

37. The method of claim 30, further comprising emitting an alarm when the color selected by the user differs from a theoretical color by a certain degree.

38. The method of claim 30, further comprising displaying a plurality of previously selected colors on the display.

39. The method of claim 30, further comprising:

selecting a turbidity level displayed on the display of the peritoneal dialysis device that most closely corresponds to a turbidity of the used dialysate exiting the peritoneal dialysis device; and

storing the selected turbidity level in the peritoneal dialysis device.
