Abstract

Graphical user interfaces for use with extracorporeal blood treatment systems may include a blood circuit pressure graphical element. The blood circuit pressure graphical element may include a venous portion and an arterial portion. The venous portion may depict, or include, a presently-monitored venous blood circuit pressure value and a graphical representation of previously-monitored venous blood circuit pressure values, and the arterial portion may depict, or include, a presently-monitored arterial blood circuit pressure value and a graphical representation of previously-monitored arterial blood circuit pressure values.

First claim

What is claimed is:

1. An extracorporeal blood treatment system comprising:
an extracorporeal blood treatment apparatus to perform an extracorporeal blood treatment, the extracorporeal blood treatment apparatus comprising:
one or more pumps,
a venous blood circuit,
an arterial blood circuit, and
two or more blood circuit pressure sensors to measure venous blood circuit pressure in the venous blood circuit and arterial blood circuit pressure in the arterial blood circuit;

a display comprising a graphical user interface configured to depict a blood circuit pressure graphical element corresponding to the measured venous blood circuit pressure and arterial blood circuit pressure and a blood flow rate area corresponding to blood flow rate of the extracorporeal blood treatment performable using the extracorporeal blood treatment apparatus; and
a processor operatively coupled to the display and the extracorporeal blood treatment apparatus, wherein the processor is configured to:
monitor blood flow rate of the extracorporeal blood treatment;
display the blood flow rate area on the graphical user interface depicting a present blood flow rate value of the extracorporeal blood treatment and comprising a blood flow rate adjustment graphical element,
allow a user to move the blood flow rate adjustment graphical element to adjust the blood flow rate of the extracorporeal blood treatment using the one or more pumps of the extracorporeal blood treatment apparatus,
monitor venous blood circuit pressure in the venous blood circuit and arterial blood circuit pressure in the arterial blood circuit of the extracorporeal blood treatment using the two or more blood circuit pressure sensors of the extracorporeal blood treatment apparatus, and
display the blood circuit pressure graphical element on the graphical user interface, wherein the blood circuit pressure graphical element is graphically emphasized in response to the blood flow rate adjustment graphical element being moved to adjust the blood flow rate of the extracorporeal blood treatment using the one or more pumps of the extracorporeal blood treatment apparatus, wherein the blood circuit pressure graphical element comprises:
a venous portion comprising:
a presently-monitored venous blood circuit pressure value of the extracorporeal blood treatment, and
a graphical representation of previously-monitored venous blood circuit pressure values of the extracorporeal blood treatment, and

an arterial portion comprising:
a presently-monitored arterial blood circuit pressure value of the extracorporeal blood treatment, and
a graphical representation of previously-monitored arterial blood circuit pressure values of the extracorporeal blood treatment.

2. A method for an extracorporeal blood treatment system comprising:
providing an extracorporeal blood treatment apparatus to perform an extracorporeal blood treatment, the extracorporeal blood treatment apparatus comprising:
one or more pumps,
a venous blood circuit,
an arterial blood circuit, and
two or more blood circuit pressure sensors to measure venous blood circuit pressure in the venous blood circuit and arterial blood circuit pressure in the arterial blood circuit;

monitoring blood flow rate of the extracorporeal blood treatment;
displaying a blood flow rate area on a graphical user interface depicting a present blood flow rate value of the extracorporeal blood treatment and comprising a blood flow rate adjustment graphical element;
allowing a user to move the blood flow rate adjustment graphical element to adjust the blood flow rate of the extracorporeal blood treatment using the one or more pumps of the extracorporeal blood treatment apparatus;
monitoring venous blood circuit pressure in the venous blood circuit of the extracorporeal blood treatment using the two or more blood circuit pressure sensors of the extracorporeal blood treatment apparatus and an arterial blood circuit pressure in the arterial blood circuit of the extracorporeal blood treatment using the two or more blood circuit pressure sensors of the extracorporeal blood treatment apparatus; and
displaying a blood circuit pressure graphical element on the graphical user interface, wherein the blood circuit pressure graphical element is graphically emphasized in response to the blood flow rate of the extracorporeal blood treatment being adjusted using the blood flow rate adjustment graphical element, wherein the blood circuit pressure graphical element comprises:
a venous portion comprising:
a presently-monitored venous blood circuit pressure value of the extracorporeal blood treatment, and
a graphical representation of previously-monitored venous blood circuit pressure values of the extracorporeal blood treatment, and

an arterial portion comprising:
a presently-monitored arterial blood circuit pressure value of the extracorporeal blood treatment, and
a graphical representation of previously-monitored arterial blood circuit pressure values of the extracorporeal blood treatment.

3. The system of claim 1 , wherein the blood circuit pressure graphical element is displayed in proximity to the blood flow rate adjustment graphical element and moves with the blood flow rate adjustment graphical element in response to the blood flow rate being adjusted using the blood flow rate adjustment graphical element.

4. The system of claim 1 , wherein a graphical size of at least a portion of the blood circuit pressure graphical element is expanded in response to the blood flow rate being adjusted using the blood flow rate adjustment graphical element.

5. The system of claim 1 , wherein the presently-monitored venous blood circuit pressure value comprises at least one of an alphanumeric representation of the presently-monitored venous blood circuit pressure value and a graphical representation of the presently-monitored venous blood circuit pressure value proximate the graphical representation of previously-monitored venous blood circuit pressure values, and wherein the presently-monitored arterial blood circuit pressure value comprises at least one of an alphanumeric representation of the presently-monitored arterial blood circuit pressure value and a graphical representation of the presently-monitored arterial blood circuit pressure value proximate the graphical representation of previously-monitored arterial blood circuit pressure values.

6. The system of claim 1 , wherein the venous portion of the blood circuit pressure graphical element further comprises a venous circuit pressure alarm limit graphical representation indicative of a venous circuit pressure alarm limit value for the monitored venous blood circuit pressure, wherein the venous circuit pressure alarm limit graphical representation is located in relation to the presently-monitored venous blood circuit pressure value to graphically indicate a quantitative difference between the presently-monitored venous blood circuit pressure value and the venous circuit pressure alarm limit value,
wherein the arterial portion of the blood circuit pressure graphical element further comprises an arterial circuit pressure alarm limit graphical representation indicative of a arterial circuit pressure alarm limit value for the monitored arterial blood circuit pressure, wherein the arterial circuit pressure alarm limit graphical representation is located in relation to the presently-monitored arterial blood circuit pressure value to graphically indicate a quantitative difference between the presently-monitored arterial blood circuit pressure value and the arterial circuit pressure alarm limit value,
wherein the processor is further configured to:
allow a user to select the venous circuit pressure alarm limit graphical representation to adjust the venous circuit pressure alarm limit v
