Powerhead control in a power injection system
First Claim
1. A contrast media injector system comprising:
- a powerhead including a display screen;
the powerhead configured to control injection of a fluid within a fluid container coupled thereto; and
a graphical element within the display screen corresponding to the fluid container and the fluid, wherein a color of the graphical element is selected based on an identity of the fluid.

Abstract
A dual head contrast media injection system performs a patency check or test injection, determining flow rate and/or flow volume from the programmed protocol. The tubing that connects syringes to a patient shares only a short common section near to the patient. Appropriate injection steps are taken to compensate for tubing elasticity. A wireless remote control and a touch screen control are provided, improving functionality and information delivery. The display brightness is controlled based on the ambient light, and the display panel includes a double swivel permitting re-orientation. The orientation of the display may also be controlled based on, e.g., the current step, the tilt angle of the powerhead, or a manual control. Furthermore, the display is customizable to identify the type of fluid (contrast, saline, etc.) on either side of the injector, to provide matched color coding, and to provide a folder/tab analogy for retrieving injection protocol parameters.
