Abstract

Extracorporeal blood treatment systems and methods to display graphical user interfaces displaying a plurality of fluids areas, each including a flow rate, and displaying adjustment notifications proximate one or more fluid areas. For example, when a user adjusts a flow rate to a limit, one or more notifications may be displayed proximate other flow rates that may be adjusted to modify the limit.

First claim

What is claimed is:

1. An extracorporeal blood treatment system comprising:
extracorporeal blood treatment apparatus for use in performing an extracorporeal blood treatment comprising:
a treatment set comprising tubing operably coupled to a patient to at least take blood from and return blood to the patient,
a plurality of pumps operably coupled to the treatment set to move blood and a treatment solution through the treatment set during extracorporeal blood treatment,
a plurality of reservoirs operably coupled to the treatment set and the plurality of pumps to store fluids during extracorporeal blood treatment, and
a plurality of reservoir scales to hold and weigh the plurality of reservoirs;

a display apparatus comprising a graphical user interface, wherein the graphical user interface is configured to depict a fluid region; and
a computing apparatus operatively coupled to the extracorporeal blood treatment apparatus and the display apparatus, wherein the computing apparatus is configured to:
provide a plurality of extracorporeal blood treatments;
configure a selected extracorporeal blood treatment from the plurality of extracorporeal blood treatments;
display on the graphical user interface a fluid region diagrammatically representative of the selected extracorporeal treatment comprising:
a plurality of pump elements representative of and corresponding to the plurality of pumps, wherein each pump element of the plurality of pump elements defines a flow rate during performance of the selected extracorporeal blood treatment, and
a fluid circuit comprising one or more fluid connections extending between the plurality of pump elements to diagrammatically represent the configuration of the treatment set for the selected extracorporeal treatment; and

perform the selected extracorporeal blood treatment.

2. The system of claim 1 , wherein the fluid region further comprises a plurality of reservoir elements representative of and corresponding to the plurality of reservoirs storing the fluid to diagrammatically represent the configuration of the plurality of reservoirs for the selected extracorporeal treatment, wherein each reservoir element of the plurality of reservoir elements comprises a fluid level representative of an amount of the fluid within the reservoir storing the fluid during performance of the extracorporeal blood treatment.

3. The system of claim 1 , wherein the treatment set further comprises a deaeration apparatus, and wherein the fluid circuit of the fluid region further comprises a deaeration apparatus element representative of and corresponding to the deaeration apparatus to diagrammatically represent the configuration of the deaeration apparatus within the treatment set for the selected extracorporeal treatment.

4. The system of claim 1 , wherein the treatment set further comprises a blood warmer, and wherein the fluid circuit of the fluid region further comprises a blood warmer element representative of and corresponding to the blood warmer to diagrammatically represent the configuration of the blood warmer within the treatment set for the selected extracorporeal treatment.

5. The system of claim 1 , wherein the treatment set further comprises one or more pressure sensors, and wherein the fluid circuit of the fluid region further comprises one or more pressure sensor elements representative of and corresponding to the one or more pressure sensors to diagrammatically represent the configuration of the one or more pressure sensors within the treatment set for the selected extracorporeal treatment.

6. The system of claim 1 , wherein the treatment set further comprises a filter, and wherein the fluid circuit of the fluid region further comprises a filter element representative of and corresponding to the filter to diagrammatically represent the configuration of the filter within the treatment set for the selected extracorporeal treatment.

7. The system of claim 1 , wherein the plurality of extracorporeal blood treatments comprises continuous ultrafiltration (SCUF), continuous veno-venous hemofiltration, (CVVH), continuous veno-venous hemodialysis (CVVHD), therapeutic plasma exchange (TPE), hemofiltration HP, hemoperfusion, continuous renal replacement therapy (CRRT), and molecular adsorbent recirculating system (MARS).

8. The system of claim 1 , wherein at least one of the plurality of extracorporeal blood treatments results a first number of the plurality of pump elements displayed in the fluid region and at least one of the plurality of extracorporeal blood treatments results a second number of the plurality of pump elements displayed in the fluid region, wherein the first number is different than the second number.

9. The system of claim 1 , wherein each of the plurality of pump elements comprises a pump icon that is graphical depiction of the type of pump used for the corresponding fluid.

10. The system of claim 9 , wherein the pump icon is graphical depiction of a peristaltic pump or a syringe.

11. A method for an extracorporeal blood treatment system comprising:
providing a plurality of extracorporeal blood treatments using extracorporeal blood treatment apparatus, wherein the extracorporeal blood treatment apparatus comprises:
a treatment set comprising tubing operably coupled to a patient to at least take blood from and return blood to the patient,
a plurality of pumps operably coupled to the treatment set to move blood and a treatment solution through the treatment set during extracorporeal blood treatment,
a plurality of reservoirs operably coupled to the treatment set and the plurality of pumps to store fluids during extracorporeal blood treatment, and
a plurality of reservoir scales to hold and weigh the plurality of reservoirs;

configuring a selected extracorporeal blood treatment from the plurality of extracorporeal blood treatments;
displaying on a graphical user interface a fluid region diagrammatically representative of the selected extracorporeal treatment comprising:
a plurality of pump elements representative of and corresponding to the plurality of pumps, wherein each pump element of the plurality of pump elements defines a flow rate during performance of the selected extracorporeal blood treatment, and
a fluid circuit comprising one or more fluid connections extending between the plurality of pump elements to diagrammatically represent the configuration of the treatment set for the selected extracorporeal treatment; and

performing the selected extracorporeal blood treatment.

12. The system of claim 11 , wherein the fluid region further comprises a plurality of reservoir elements representative of and corresponding to the plurality of reservoirs storing the fluid to diagrammatically represent the configuration of the plurality of reservoirs for the selected extracorporeal treatment, wherein each reservoir element of the plurality of reservoir elements comprises a fluid level representative of an amount of the fluid within the reservoir storing the fluid during performance of the extracorporeal blood treatment.

13. The system of claim 11 , wherein the treatment set further comprises a deaeration apparatus, and wherein the fluid circuit of the fluid region further comprises a deaeration apparatus element representative of and corresponding to the deaeration apparatus to diagrammatically represent the configuration of the deaeration apparatus within the treatment set for the selected extracorporeal treatment.

14. The system of claim 11 , wherein the treatment set further comprises a blood warmer, and wherein the fluid circuit of the fluid region further comprises a blood warmer element re
