Abstract

The present application discloses a portable dialysis system for conducting a dialysis treatment. The portable dialysis system has a controller unit that includes a display, a scale, a bar code reader, and a memory storing a plurality of programmatic instructions. Upon execution, the instructions generate a first graphical user interface, a second graphical user interface, and a third graphical user interface for presentation on the display. The first graphical user interface displays each additive required for use in the dialysis treatment. The second graphical user interface prompts a user to submit additives to scanning using the bar code scanner. The third graphical user interface prompts a user to submit additives to measurement using the scale.

Claims

1. A portable dialysis system for conducting a dialysis treatment, wherein said portable dialysis system comprises:

a. first housing having a display and having a dialyzer, plurality of pumps and fluid flow paths for conducting said dialysis treatment;

b. a second housing having water reservoir, a scale and a bar code reader, wherein the first housing is adapted to physically attach to, and sit on top of, the second housing and wherein a fluid flow path places water in said water reservoir in fluid communication with at least one of the fluid flow paths in the first housing; and

c. a memory, located in the first housing, for storing a plurality of programmatic instructions wherein, upon execution, said instructions generate;

i. a first graphical user interface for presentation on said display, wherein said first graphical user interface displays each additive required for use in the dialysis treatment;

ii. a second graphical user interface for presentation on said display, wherein said second graphical user interface prompts a user of said system to submit a plurality of additives to scanning using said bar code scanner; and

iii. a third graphical user interface for presentation on said display, wherein said third graphical user interface prompts a user of said system to submit a plurality of additives to measurement using said scale.

2. The dialysis system of claim 1 wherein said scale is a digital scale.

3. The dialysis system of claim 2 wherein said digital scale further comprises a plurality of hall sensors.

4. The dialysis system of claim 2 wherein said second housing a reservoir and said digital scale.

5. The dialysis system of claim 1 wherein the bar code scanner provides a visual indication of a successful read.

6. The dialysis system of claim 1 wherein the memory further comprises a table associating a plurality of additive names with a plurality of bar codes.

7. The dialysis system of claim 1 wherein the memory further comprises a table associating a plurality of additives with a plurality of weight values.

8. The dialysis system of claim 1 wherein the first graphical user interface displays a visual representation of the additive packaging.

9. The dialysis system of claim 1 wherein said third graphical user interface only prompts the user of said system to submit a plurality of additives to measurement using said scale if a bar code of an additive is not recognized.

10. The dialysis system of claim 1 wherein said third graphical user interface only prompts the user of said system to submit a plurality of additives to measurement using said scale if a bar code for an additive is not available.

11. A portable dialysis system for conducting a dialysis treatment, wherein said portable dialysis system comprises:

a. first housing having a display and having a dialyzer, a plurality of pumps and fluid flow paths for conducting said dialysis treatment;

b. a second housing having a scale comprising a water reservoir, a plurality of magnets and a bar code reader, wherein the first housing is adapted to physically attach to the second housing and wherein a fluid flow path places water in said water reservoir in fluid communication with at least one of the fluid flow paths in the first housing; and

c. a memory, located in the first housing, for storing a plurality of programmatic instructions wherein, upon execution, said instructions generate;

i. a first graphical user interface for presentation on said display, wherein said first graphical user interface prompts a user of said system to submit a plurality of additives to scanning using said bar code scanner; and

ii. a second graphical user interface for presentation on said display, wherein said second graphical user interface prompts a user of said system to submit a plurality of additives to measurement using said scale.

12. The portable dialysis system of claim 11 wherein, upon execution, said instructions further generate a third graphical user interface for presentation on said display, wherein said third graphical user interface displays each additive required for use in the dialysis treatment.

13. The dialysis system of claim 11 wherein said scale is a digital scale and wherein said digital scale generates data representative of a weight of an object placed on said digital scale.

14. The dialysis system of claim 13 wherein said digital scale further comprises at least three flexures.

15. The dialysis system of claim 14 wherein each of said flexures comprises a magnet and a corresponding hall sensor.

16. The dialysis system of claim 13 wherein said second housing a reservoir and said digital scale.

17. The dialysis system of claim 11 wherein the memory further comprises a table associating a plurality of additive names with a plurality of bar codes.

18. The dialysis system of claim 11 wherein the memory further comprises a table associating a plurality of additives with a plurality of weight values.

19. The dialysis system of claim 11 wherein said second graphical user interface only prompts the user of said system to submit a plurality of additives to measurement using said scale if a bar code of an additive is not recognized.

20. The dialysis system of claim 11 wherein said second graphical user interface only prompts the user of said system to submit a plurality of additives to measurement using said scale if a bar code for an additive is not available.
