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.

72. A medical fluid injector system comprising:
-
a powerhead comprising a powerhead housing; a syringe mounted to said powerhead housing and having a movable plunger disposed within said syringe, wherein at least a portion of said syringe is located outside said powerhead housing; a motorized drive having a syringe ram designed both to move in and out of said powerhead housing to cause movement of said plunger within the syringe; and a touch screen display incorporated into said powerhead housing and configured to provide an interactive user interface for controlling the system, wherein a first screen presentable on said touch screen display comprises a button, and wherein pressing said button alters an orientation of an output on said first screen. - View Dependent Claims (73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98)
