Abstract

Automated injection system disclosed in this application advantageously provides physicians with a simplified interface for selecting fluid sources, such as saline, contrast, or a mixture of both, to inject at high pressures. The injector system may comprise a multi-use subassembly, a single-use subassembly, a fitting to fluidly connect the multi-use and single-use subassemblies, a hand held controller, a user interface, and an injector housing.

Claims

1. A method to provide injection system parameters, comprising:

providing a user interface having a touchscreen display;

displaying on a first screen of the touchscreen display a plurality of selectable options for controlling the injection system;

receiving a user selection for one of the selectable options;

changing a system parameter or setting as a result of the user selection.

2. The method of claim 1, further comprising notifying user with a visual notification after receiving the user selection.

3. The method of claim 1, wherein the user interface further includes a display unit that is attached to the injection system or a bed rail.

4. The method of claim 1, wherein the user selection for one of the selectable options further comprises of contrast ration option, flow rate option, volume option, pressure option, rise time option, or arm option.

5. The method of claim 1, wherein the user selection for one of the selectable options further consists of a cardiac procedure option, a peripheral procedure option, or a physician list option.

6. The method of claim 5, wherein changing a system parameter or setting includes a preset injection parameter being populated.

7. The method of claim 6, wherein the preset injection parameters further consists of at least two of the following:

contrast to saline ratio, flow rate, volume, pressure, or rise time.

8. The method of claim 6, further comprising:

displaying a second screen which is different from the first screen.

9. The method of claim 8, further comprising the step:

selecting to arm the injection system after all of the injection parameters have been set by the user.

10. The method of claim 9, further comprising the step:

displaying a third screen which is different from the second screen that allows the user to inject fluid into the patient.

11. The method of claim 2, wherein the visual indication may comprises of one of the following:

a disposable sub-assembly has been properly installed, the injection system has been armed, the injection system is performing an injection, or the injection system has been disarmed.

12. The method of claim 3, wherein the display unit is attached to the bed rail or injector system by a movable arm.

13. The method of claim 12, further comprising the steps of:

pulling the moveable arm closer to the user; and

folding the movable arm.

14. The method of claim 8, wherein the first screen comprises of a dashboard screen and the second screen consists of an armed dashboard screen.

15. The method of claim 8, further comprising the step of:

displaying on the dashboard screen a plurality of selectable options for controlling the injection parameters.

16. The method of claim 15, wherein the step of displaying on the dashboard screen a plurality of selectable options for controlling the injection parameters includes a contrast option for changing the contrast to saline ratio.

17. A method to provide injection system parameters, comprising:

providing a user interface having a touchscreen display;

displaying on a first screen of the touchscreen display a plurality of injection parameter options; and

receiving a user selection for one of the plurality of injection parameter options.

18. The method of claim 17, further comprising the step of:

displaying on a second screen a preset injection parameter based on the users selection.

19. The method of claim 18, wherein the second screen further comprises an option to arm the injection system.

20. The method of claim 19, further comprising the step of:

receiving the user input to arm the injection system; and

displaying an option to inject fluid into the patient.
