Abstract: A hand-held remote for a medical fluid injector includes a syringe and a conduit which may be coupled to a pressure transducer on a control circuit of the injector. Movement of a plunger within a syringe body on the syringe creates a pressure which is sensed by the pressure transducer and the control circuit responds to the sensed pressure by causing fluid to be ejected from, or drawn into, a syringe mounted to the injector. The pressure developed by the remote provides tactile feedback to an operator for improved control over injections.

Abstract: An injector that may be used to deliver radiographic contrast media and/or flushing solution into a patient's vascular system for the purposes such as obtaining enhanced diagnostic x-ray images. The injector includes a drive ram movable along its longitudinal axis, and a control system that controls operation of the injector. The control system has an enabled state that allows an injection procedure to be performed, and a disabled state that does not allow an injection procedure to be performed. The control system transitions from the disabled state to the enabled state in response to movement of the drive ram along its longitudinal axis.

Abstract: A contrast media injection system 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.
