Abstract

A graphical user interface for a medical instruments for a Renal Replacement Therapy is disclosed that includes a pictogram representation of the fluid path of an extracorporeal blood circuit that represents fluid lines, pumps and sensors. To assist the user in responding to alarms and rectifying faults in the system the source of a potential trouble is animated. The location of a trouble spot is easily identified by flashing of the corresponding element of the pictogram, change of color or thickness of a corresponding line.

Claims

1. A method to assist an operator in identifying a fault in a fluid path of a renal replacement therapy device comprising the steps of:

a. drawing blood from a patient into the fluid path, passing the blood through the path in the device, and returning the blood from the fluid path into the patient;

b. detecting a fault in the fluid path;

c. displaying a pictorial diagram of the fluid path on the machine graphic display, wherein said diagram further comprises a plurality of fluid path diagram segments, and

d. accentuating one segment of said plurality of fluid path diagram segments, wherein said one segment accentuated corresponds to a segment of the fluid path where said fault is detected, and wherein at least one other segment of said plurality of fluid path diagram segments is not accentuated.

2. A method as in claim 1 wherein the fault in the fluid path is an air bubble in the fluid path, in step (b) a location of the air bubble is detected, and in step (d) the one segment accentuated corresponds to the detected location of the air bubble in the fluid path.

3. A method as in claim 1 wherein the fault in the fluid path is a blood leak in the fluid path, in step (b) a location of the blood leak is detected, and in step (d) the one segment accentuated corresponds to the detected location of the blood leak in the fluid path.

4. A method as in claim 1 wherein the fault in the fluid path is an occlusion in the fluid path, in step (b) a location of the occlusion is detected, and in step (d) the one segment accentuated corresponds to the detected location of the occlusion in the fluid path.

5. A method as in claim 1 wherein the fault in the fluid path is in a filter in the fluid path, and in step (d) the one segment accentuated corresponds to the filter.

6. A method as in claim 1 wherein the pictorial diagram of the fluid path includes a line drawing showing the fluid path from the patient through the device and back to the patient, and the one segment accentuated is a section of the line drawing of the fluid path corresponding to a location in the fluid path where the fault is located.

7. A method as in claim 1 further comprising displaying a text message regarding the fault adjacent the pictorial diagram.

8. A method as in claim 1 further comprising displaying a text message of a procedure to cure the fault and said text message is displayed adjacent the pictorial digram.

9. A method as in claim 1 further comprising monitoring sensors coupled to the device to detect the fault in the fluid path.

10. A method as in claim 1 further comprising sensing a pressure in the fluid path and detecting a fault in the fluid path if the sensed pressure varies from a predetermined level of pressure.

11. A method as in claim 1 further comprising optically sensing the blood through the path to detect bubble faults in the fluid path.

12. A method as in claim 1 wherein the fluid path includes a filtrate path extending from a blood filter and accentuating the filtrate path of the pictorial diagram when a fault is detected in the filtrate path.

13. A method to assist an operator in identifying a fault in a fluid path of a renal replacement therapy device comprising:

a. drawing blood from a patient into the fluid path, passing the blood through the path in the device, and returning the blood from the fluid path into the patient;

b. detecting a fault in the fluid path;

c. displaying a pictorial diagram of the fluid path on the machine graphic display, and

d. accentuating an element of the diagram of the fluid path where the fault has been detected,

wherein the pictorial diagram includes a first view of the fluid path and a second view of the fluid path, and further comprising selecting the first view or second view to be displayed in step (c) depending on the detected fault.

14. A method to assist an operator in identifying a fault in a fluid path of a renal replacement therapy device comprising the steps of:

a. drawing blood from a patient into the fluid path, passing the blood through the path in the device, and returning the blood from the fluid path into the patient;

b. detecting a fault in the fluid path;

c. displaying a pictorial diagram of the fluid path on the machine graphic display, and

d. accentuating an element of the diagram of the fluid path where the fault has been detected.

wherein the pictorial diagram includes a front view of the fluid path and a side view of the fluid path, and further comprising selecting the front view or side view to be displayed in step (c) depending on the detected fault.

15. A method to assist an operator in identifying a fault in a fluid path of a renal replacement therapy device comprising the steps of:

a. drawing blood from a patient into the fluid path, passing the blood through the path in the device, and returning the blood from the fluid path into the patient;

b. detecting a fault in the fluid path;

c. displaying a pictorial diagram of the fluid path on the machine graphic display, and

d. accentuating an element of the diagram of the fluid path where the fault has been detected,

further comprising the step of displaying a pictorial diagram of a pump adjacent the diagram of the fluid path, and rotating the diagram of the pump while blood flows through the fluid path.
