System and method for dispensing product to a washing machine. A chemical dispensing system includes a system controller, machine interface, and pump controller that communicate through serial data buses. The system controller provides a user interface, retrieves washing machine status information from the machine interface, and issues product dispensing commands to the pump controller. The pump controller monitors pump status and dispenses product in response to commands from the system controller. The pump controller: (1) determines pump activation periods based on calibration data stored in a pump controller memory; (2) tracks pump usage and adjusts the activation period to compensate for pump wear as the pump ages; (3) disables the pump if conditions exists that preclude operating the pump; (4) monitors product levels, and (5) reports pump status to the system controller. Integral channels are included in the pump housing to provide stress relief to a squeeze tube.

Intelligent network for chemical dispensing system

A status messaging protocol () for a power injector () is disclosed. A setup screen () may be displayed on a graphical user interface () associated with the power injector (). A status message () is displayed in a status message zone () on the setup screen (). As the status of the power injector () changes, the status message () in the status message zone () on the setup screen () is updated.

A flow rate assessment protocol () that may be utilized by a power injector () is disclosed. This flow rate assessment protocol () monitors a flow rate () during execution of a medical fluid delivery protocol (). This monitored flow rate is compared with a target flow rate (). A comparative output of this monitored flow rate and target flow rate is displayed (), for instance on a graphical user interface ().

Power injector with flow rate assessment

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.
