A power injector () is disclosed that includes a number of features to address leakage of contrast media from a syringe that may occur while operating the power injector (), for instance when loading fluid into a syringe after being installed on a powerhead () of the injector () and/or when purging air from such a syringe. One or more drainage channels () may be incorporated on a faceplate mounting () which in turn receives a faceplate (), which in turn receives a syringe. A cover assembly () may utilize a form-in-place gasket () between its top cover () and its bottom cover (). A bezel () includes an overlay () that is disposed over a touch screen display () that is aligned with a display aperture () through the top cover (), and the bezel () may include a gasket () to seal against the top cover ().

Single-head power injector with contrast media leakage management

A medical fluid injector system () is disclosed that may utilize one or more of flow rate determination logic (), injection volume determination logic (), display control logic (), drive ram motion control logic (), and pressure monitoring logic (). The flow rate determination logic (), injection volume determination logic (), and display control logic () each may utilize a concentration input () to calculate flow rates, injection volumes, and generate multi-color graphics, respectively, for a simultaneous injection configuration. The drive ram motion control logic () may utilize both a target pressure and a monitored pressure to derive a velocity for advancing a drive ram. The pressure monitoring logic () may provide a monitored pressure value for the drive ram control logic (), where this monitored pressure value may be derived from the input power being used to advance a drive ram and the drive ram velocity.

Medical fluid injector system

A contrast media injection system includes detects the absolute position of the syringe ram using a non-contact sensor. A series of magnets and Hall-Effect sensors may be used or an opto-reflective system. Illuminated knobs that are connected to the drive mechanism for the syringe ram rotate with the drive and provide visual feedback on operation through the illumination. Analog Hall-Effect sensors are used to determine the presence or absence of magnets that identify the type of faceplate being used. The faceplates include control electronics, connected to the powerhead through connectors, which may be interchangeably used by the two faceplates. The faceplate electronics include detectors for automatically detecting the capacity of pre-filled syringes. Additional features include using historical data to provide optimum pressure limit values during an injection protocol, a removable memory device for storing and transferring information such as injection protocols and injector statistics, and password protection of such protocols.

Powerhead of a power injection system

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.

Powerhead control in a power injection system

The present invention relates to management of information relating to medical fluids, containers therefore, and medical fluid administration devices for administering such medical fluids to patients. Data tags (e.g., RFID tags) are generally associated with containers of the invention and may be electromagnetically read from and/or written to using an electromagnetic device, for example, that may be associated with a medical fluid administration device of the invention.

Systems and methods for managing information relating to medical fluids and containers therefor

A contrast medium injector for injecting a patient with contrast medium for a CT scan is programmed to provide an injection protocol that is a representation of an ideally defined exponential curve with an initial injection rate decaying at an exponential rate. This has been found to produce a uniform vascular enhancement for the scanning of a patient's blood vessels. The particular exponential decay coefficient which has been found to be optimal is directly proportional to the cardiac output divided by the patient's weight and is approximated at 0.01 for a typical human.

Contrast injector for injecting a contrast medium to generate prolonged uniform vascular enhancement

A system to provide a specified volume of a medical fluid from a bulk source to a dose and/or delivery container for injection into a patient. The fluid path between the bulk container and the delivery container is physically separated at a connecting site before fluid is injected from the delivery container into the patient. The bulk container may be a bag or bottle, and the delivery container may be a syringe or bag. A bag delivery container may be contained in a pressurizeable chamber and fluid may be delivered by providing pressure to a membrane in the chamber contacting a wall of the bag. The system may be automated.
