Powerhead control in a power injection system

摘要

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.

主权项

1. A contrast media injector system comprising:
a powerhead including a display screen; the powerhead configured to control injection of a fluid from within a fluid container coupled thereto to a patient through tubing connected to the fluid container; a first iconic graphical element within the display screen representing the fluid container and the fluid therein, wherein a color of the graphical element is selected based on an identity of the fluid; and a second iconic graphical element within the display screen representing the tubing and the fluid therein, wherein a color of the second iconic graphical element is substantially identical to the color of the first iconic graphical element, and wherein the second iconic graphical element extends from the first iconic graphical element on the display screen.
