Abstract

One embodiment provides a method of using contextual lighting to assist a user of a medical fluid injection system. In this embodiment, the method includes providing a lighted display in proximity to a component of the injection system during setup of the medical fluid injection system. If the user has properly performed a setup function that is associated with the component of the injection system, the method further comprises providing a first visual indication on the lighted display. If the user has not properly performed the setup function that is associated with the component of the injection system, the method further comprises providing a second visual indication on the lighted display.

a first air detector to detect air in the first tubing component; and

a second air detector to detect air the in the second tubing component.

7. The system of claim 6, wherein:

the syringe includes an inlet port and an outlet port;

the first tubing component is configured to carry fluid from the first fluid reservoir to the inlet port of the syringe; and

the second tubing component is configured to carry fluid from the outlet port of the syringe to the patient line.

8. The system of claim 6, further comprising:

a first valve to control fluid flow through the first tubing component; and

a second valve to control fluid flow through the second tubing component.

9. The system of claim 8, wherein the first and second valves comprise pinch valves.

10. The system of claim 6, further comprising:

a peristaltic pump to pump fluid from a second fluid reservoir to the patient line.

11. The system of claim 6, further comprising:

a second syringe;

a third tubing component to carry fluid from a second fluid reservoir to the second syringe;

a fourth tubing component to carry fluid from the second syringe to the patient line;

a third air detector to detect air in the third tubing component; and

a fourth air detector to detect air the in the fourth tubing component.

12. The system of claim 11, wherein:

the second syringe includes an inlet port and an outlet port;

the third tubing component is configured to carry fluid from the second fluid reservoir to the inlet port of the second syringe; and

the fourth tubing component is configured to carry fluid from the outlet port of the second syringe to the patient line.

13. The system of claim 6, further comprising:

a second console to receive input from the user, wherein both the console and the second console are coupled to an injector head of the system.

14. The system of claim 6, further comprising:

a portable console remotely coupled to the injector head, the portable console capable of receiving input from the user and also capable of displaying information to the user.

15. A disposable fluid connector to be used with a powered injector that injects medical fluid into a patient, the disposable fluid connector comprising:

a first tubing component having proximal and distal ends, the proximal end to be operatively coupled to an output of a first pressurizing unit of the powered injector, and the distal end to be operatively coupled to a patient line;

a second tubing component having proximal and distal ends, the proximal end of the second tubing component to be operatively coupled to an output of a second pressurizing unit of the powered injector, and the distal end of the second tubing component to be operatively coupled to the patient line; and

a member that is non-removably attached to both the first tubing component and the second tubing component,

wherein the disposable fluid connector is a single-use connector that is coupled as one assembly to the powered injector before a patient injection procedure and is discarded upon completion of the procedure.

16. The disposable fluid connector of claim 15, further comprising:
