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.

First claim

What is claimed is:

1. A powered system to deliver medical fluid to a patient, the system comprising:
a console to receive input from a user;
first and second syringes that each include an inlet port and an outlet port that is different from the respective inlet port;
a first tubing component to carry fluid from a first fluid reservoir to the inlet port of the first syringe;
a second tubing component to carry fluid from the outlet port of the first syringe to a patient line;
a third tubing component to carry fluid from a second fluid reservoir to the inlet port of the second syringe;
a fourth tubing component to carry fluid from the outlet port of the second syringe to the patient line;
first, second, third, and fourth sensors to detect air in the respective first, second, third, and fourth tubing components;
first, second, third, and fourth valves to control fluid flow through the respective first, second, third, and fourth tubing components, wherein a portion of the first tubing component runs through the first sensor and the first valve, wherein a portion of the second tubing component runs through the second sensor and the second valve, wherein a portion of the third tubing component runs through the third sensor and the third valve, and wherein a portion of the fourth tubing component runs through the fourth sensor and the fourth valve; and
first, second, third, and fourth doors to cover the respective portion of the respective first, second, third, and fourth tubing components, wherein the first door is hinged to an edge of a first assembly that includes the first valve and the first sensor, wherein the second door is hinged to an edge of a second assembly that includes the second valve and the second sensor, wherein the third door is hinged to an edge of a third assembly that includes the third valve and the third sensor, and wherein the fourth door is hinged to an edge of a fourth assembly that includes the fourth valve and the fourth sensor.

2. The system of claim 1 , wherein the first, second, third, and fourth valves comprise pinch valves.

3. The system of claim 1 , 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.

4. The system of claim 1 , 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.

5. The system of claim 1 ,
wherein the first sensor is positioned to detect air in the first tubing component between the first valve and the inlet port of the first syringe,
wherein the second sensor is positioned to detect air in the second tubing component between the second valve and the patient line,
wherein the third sensor is positioned to detect air in the third tubing component between the third valve and the inlet port of the second syringe, and
wherein the fourth sensor is positioned to detect air in the fourth tubing component between the fourth valve and the patient line.

6. The system of claim 1 , wherein at least one of the first door, the second door, the third door, or the fourth door is transparent or translucent.
