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.

First claim

The invention claimed is:

1. A peritoneal dialysis device, comprising:
a drainage conduit configured to receive used dialysate from a patient; and
a display, wherein
a portion of the drainage conduit is positionable at a location adjacent a region of the display, and
the peritoneal dialysis device is configured to display a plurality of colors in a designated window on the region of the display, the plurality of colors corresponding to a plurality of turbidity levels of dialysate,
wherein the peritoneal dialysis device is configured such that a color currently displayed in the designated window on the display can be selected for input into the peritoneal dialysis device as a color that most closely corresponds to a color of the used dialysate in the portion of the drainage conduit, and
wherein the peritoneal dialysis device is configured to operate according to at least one of: a) at least first and second colors of the plurality of colors are simultaneously displayed in the designated window on the display for selection and b) a first color of the plurality of colors is displayed in the designated window on the display for selection and can be changed to at least a second color of the plurality of colors.

2. The device of claim 1 , wherein the peritoneal dialysis device is configured to store a color selected by a user.

3. The device of claim 2 , wherein the peritoneal dialysis device comprises memory for storing the color selected by the user.

4. The device of claim 2 , wherein the peritoneal dialysis device comprises a removable storage medium on which the color selected by the user is stored together with alphanumeric data.

5. The device of claim 4 , wherein the removable storage medium comprises a memory chip, and the alphanumeric data comprises patient data.

6. The device of claim 1 , wherein the display is in the form of a touch screen.

7. The device of claim 1 , wherein the display comprises an illumination field configured to illuminate the used dialysate in the drainage conduit.

8. The device of claim 1 , 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.

9. The device of claim 8 , wherein the alarm is a visual alarm displayed in an alarm field of the display.

10. The device of claim 1 , wherein the peritoneal dialysis device is configured to simultaneously display in a second designated window on the display a plurality of colors previously selected by a user of the peritoneal dialysis device and stored on a storage medium.

11. A peritoneal dialysis method, comprising:
displaying a plurality of colors in a designated window on a region of a display of a peritoneal dialysis device, the plurality of colors corresponding to a plurality of turbidity levels of dialysate, wherein a) at least first and second colors of the plurality of colors are simultaneously displayed in the designated window on the display for selection by a user or b) a first color of the plurality of colors is displayed in the designated window on the display for selection by a user and can be changed to at least a second color of the plurality of colors;
positioning a drainage conduit at a location adjacent to the region of the display, the drainage conduit being configured to receive used dialysate from a patient;
comparing a color of used dialysate within the drainage conduit to the plurality of colors displayed on the region of the display;
selecting, by input into the peritoneal device, a color from the plurality of colors displayed on the region of the display that most closely corresponds to a color of the used dialysate within the drainage conduit; and
storing the selected color in the peritoneal dialysis device.

12. The method of claim 11 , wherein the selected color is stored in memory of the peritoneal dialysis device.

13. The method of claim 11 , wherein the selected color is stored on a removable storage medium of the peritoneal dialysis device.

14. The method of claim 11 , wherein the selected color is stored together with alphanumeric values.

15. The method of claim 14 , wherein the alphanumeric values comprise patient data.

16. The method of claim 11 , further comprising displaying a color spectrum on the display, wherein the selected color is one of multiple colors on the color spectrum.

17. The method of claim 11 , further comprising illuminating the used dialysate in the drainage conduit in order to allow the user to select the displayed color that most closely corresponds to the color of the used dialysate.

18. The method of claim 11 , further comprising emitting an alarm when the color selected by the user differs from a theoretical color by a certain degree.

19. The method of claim 11 , further comprising displaying a plurality of previously selected colors on the display.

20. The method of claim 11 , 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.

21. The device of claim 1 , wherein the display comprises an illumination field configured to illuminate the used dialysate in the drainage conduit, the illumination field being disposed at a location adjacent the region of the display used to display the plurality of colors.

22. The method of claim 11 , further comprising
positioning the drainage conduit over an illumination field on the display, the illumination field configured to illuminate the used dialysate in the drainage conduit; and
illuminating the used dialysate in the drainage conduit via the illumination field in order to allow the user to select the displayed color that most closely corresponds to the color of the used dialysate.

23. The device of claim 1 , wherein the color currently displayed in the designated window can be selected for input by at least one of pressing a button, touching an area of the display operating as a touch screen, using a keyboard, and using a mouse.

24. The device of claim 1 , wherein the at least first and second colors are simultaneously displayed in the designated window and can be input for selection by at least one of pressing a button, touching an area of the display operating as a touch screen, using a keyboard, or using a mouse.

25. The device of claim 1 , wherein the first color is displayed in the designated window on the display and can be input for selection by at least one of pressing a button, touching an area of the display operating as a touch screen, using a keyboard, and using a mouse, wherein the first color can be changed to at least a second color of the plurality of colors of a color spectrum by at least one of pressing a button, touching an area of the display operating as a touch screen, using a keyboard, and using a mouse.

26. The device of claim 1 , wherein the display is in the form of a touch screen, and the at least first and second colors are simultaneously displayed at first and second positions in the designated window on the touch screen, and selectable by a user by touching the touch screen in the first and second positions, respectively.
