User interface for blood treatment device
View Patent ↗A graphical user interface for a medical instruments for a Renal Replacement Therapy includes a pictogram representation of cthe 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.
1. A graphical user interface for a blood treatment device having a blood path, said user interface comprising:
a display further comprising a pictogram of the blood treatment device illustrating a first section of the blood path and a second section of the blood path;
a controller for the device configured for generating the pictogram of the blood treatment device and blood path to be displayed;
the pictogram on the display accentuates alternatively the first section and the second section depending on a location of an element of the blood path identified by the controller that requires user attention.
2. A graphical user interface as in claim 1 wherein the pictogram flashes in alternating colors just one of said first or second sections to designate a leakage of blood in the blood path detected by the controller sensing a pressure in the path.
3. A graphical user interface as in claim 1 wherein the pictogram flashes in alternating colors just one of said first or second sections to designate a location of an occlusion of the blood path detected by the controller.
4. A graphical user interface as in claim 1 wherein the pictogram flashes in alternating colors just one of said first or second sections to designate a location of a leakage of blood in the blood path detected by the controller.
5. A graphical user interface as in claim 1 wherein the pictogram flashes in alternating colors the first section represents the blood path between a withdrawal catheter and a blood filter and the said first section to designate a leakage of blood detected by the controller analyzing a pressure between the patient blood withdrawal catheter and the blood filter.
6. A graphical user interface as in claim 1 wherein the second section represents the blood path between a blood filter and an infusion catheter and the pictogram flashes in alternating colors the second section to designate a leakage of blood detected by an analysis by the controller of a pressure between the infusion catheter and the blood filter.
7. A graphical user interface as in claim 1 wherein the first section represents the blood path between a withdrawal catheter and a blood filter and the pictogram flashes in alternating colors the first section an occlusion is detected by the controller based on a pressure between the withdrawal catheter and the blood filter.
8. A graphical user interface as in claim 1 wherein the second section represents the blood path between a blood filter and an infusion catheter and the pictogram flashes in alternating colors when an occlusion is detected by the controller based on a pressure between the blood filter and the infusion catheter.
9. A graphical user interface as in claim 1 wherein the pictogram flashes a symbol of a blood roller pump of the device when a pump jam is detected by the controller.
10. A graphical user interface as in claim 1 wherein the pictogram flashes a symbol of a blood roller pump if an occlusion of a blood filter is detected by the controller analyzing an electric current through a pump motor of the roller pump.
11. A graphical user interface as in claim 1 wherein the device is an ultrafiltration device.
12. A graphical user interface as in claim 1 wherein the first section is a front of the device and the second section is a side of the device.
13. A graphical user interface as in claim 1 wherein the first section shows a portion of a blood path upstream of a blood filter and the second section shows a second portion of the blood path downstream of the blood filter.
14. A graphical user interface as in claim 1 wherein the pictogram displays the first section to indicate a leakage of blood is detected in the first portion of the blood path, and alternatively the pictogram displays the second section to path indicate a leakage of blood detected in the second section of the blood path.
