Abstract

A peritoneal dialysis machine includes an enclosure; dialysate pump located within the enclosure; a graphical user interface connected to the enclosure and configured to display a parameter associated with the dialysate pump; and a projector configured to project the parameter onto a surface external from the enclosure so as to allow a patient to readily view the parameter.

Claims

1. A dialysis machine comprising:

an enclosure;

a graphical user interface (“

GUI”

) connected to the enclosure and configured to display a parameter associated with the dialysate pump; and

a projector configured to project the parameter onto a surface external from the enclosure so as to allow a patient to readily view the parameter.

2. The dialysis machine of claim 1, wherein the parameter is selected from the group consisting of (i) total pump fill;

(ii) total pump dwell time;

(iii) total pump drain;

(iv) pump fill remaining;

(v) pump dwell remaining;

(vi) pump drain remaining;

(vii) total number of fill/dwell/drain cycles; and

(viii) current fill/dwell/drain cycle.

3. The dialysis machine of claim 1, the graphical user interface and projector further operable to display at least one of:

(i) the current time, (ii) ambient temperature, (iii) total ultrafiltration removed, and (iv) a time remaining for treatment.

4. The dialysis machine of claim 1, which includes a switch configured so that the patient can selectively project the parameter onto the surface.

5. The dialysis machine of claim 1, which includes a remote device configured to operate with the GUI, so as to navigate to and modify the displayed and projected parameter.

6. The dialysis machine of claim 5, the GUI and projector further configured to display and project, respectively, the modified parameter.

7. The dialysis machine of claim 5, the remote device communicating with the GUI via wired or wireless communication.

8. A dialysis machine comprising:

an enclosure;

a dialysate pump located within the enclosure;

a user interface connected to the enclosure and configured to display a parameter associated with the dialysate pump; and

at least one control feature for controlling the dialysate pump parameter, the control feature selected from the group consisting of;

(i) a keyboard projected from the enclosure and displayed on a surface separate from the enclosure;

(ii) a touch screen with tactile feedback;

(iii) a Braille interface; and

(iv) a telecommunications device for the deaf (“

TDD”

) interface.

9. The dialysate machine of claim 8, wherein the enclosure includes at least one feature selected from the group consisting of:

(i) a grip for a twist cap;

(ii) fingers for a pull cap;

(iii) an apparatus configured to break a frangible seal;

(iv) a drawer for supplies;

(v) a clamp configured to enable a patient to disconnect temporally from the machine;

(vi) a night/reading light; and

(vii) a utensil holder.

10. The dialysis machine of claim 8, wherein the user interface includes at least one feature selected from the group consisting of:

(i) a timer;

(ii) an alarm clock;

(iii) a music player;

(iv) patient selectable screen saver;

(v) a patient selectable bezel; and

(vi) a patient calendar.

11. The dialysis machine of claim 8, wherein the projected keyboard is provided via a laser, the keyboard operating with an infrared plane of light that is interrupted to provide at least a portion of the control feature for controlling the dialysate pump parameter.

12. The dialysis machine of claim 8, wherein the tactile feedback touch screen includes one of:

(i) tactile bumps molded into an overlay of the touch screen;

(ii) a sheet including tactile bumps laminated to the touch screen; and

(iii) epoxy spots adhered to the touch screen.

13. The dialysis machine of claim 8, wherein the Braille interface includes characters formed in a touch screen overlay.

14. The dialysis machine of claim 8, wherein the TDD includes a telephone connection, a keyboard and a video monitor.

15. A dialysis machine comprising:

a dialysate pump; and

a graphical user interface (“

GUI”

) allowing a patient to program a treatment including at least one patient fill using the dialysate pump, at least one dwell, and at least one patient drain using the dialysate pump,

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.

16. The dialysate machine of claim 15, the alert a tactile, audio, visual or audio-visual alert.

17. The dialysis machine of claim 15, 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.

18. The dialysis machine of claim 15, the GUI alert providing an amount of time for setting up the treatment.

19. A dialysis machine comprising:

a dialysate pump; and

a graphical user interface (“

GUI”

) allowing a patient to program a treatment including at least one patient fill using the dialysate pump, at least one patient dwell, and at least one patient drain using the dialysate pump,

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

20. The dialysis machine of claim 19, 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.
