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.

Claims

1-14. -14. (canceled)

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:

a connection to connect the disposable fluid connector to an external medical device.

17. The disposable fluid connector of claim 15, wherein the connector is configured to be loaded into a portion of an injection head in the powered injector.

18. The disposable fluid connector of claim 15, wherein:

the proximal end of the first tubing component, when connected to the powered injector, is coupled to an output of a first syringe; and

the proximal end of the second tubing component, when connected to the powered injector, is coupled to an output of a second syringe.

19. The disposable fluid connector of claim 18, wherein:

the distal end of the first tubing component is coupled to a first input port of a fluid valve;

the distal end of the second tubing component is coupled to a second input port of the fluid valve; and

an output port of the fluid valve is coupled to the patient line.

20. The disposable fluid connector of claim 19, wherein the fluid valve is an elastomeric valve.
