Abstract: A system for producing an image of a patient preferably includes a source of contrast medium, a pressurizing unit operably associated with the source of contrast medium for injecting the contrast medium into the patient, an imaging unit providing an internal image of the patient based upon a condition of the contrast medium in the patient, a control unit adapted to adjust the condition of the contrast medium injected into the patient, an electronic interface in communication with at least one of the pressurizing unit and the imaging unit, and a fluid path disposed between the pressurizing unit and the patient.

Abstract: An apparatus and method enabling the injection of fluid media into a plurality of patients is provided, including a fluid supply source providing multiple doses, a metering device for measuring the doses, a pressurizing device to effect injection, a contamination prevention device disposed between the fluid source and the patient and, when desired, an electronic control device to integrate operation of the apparatus and process.

Abstract: A disposable unit for delivering fluid medium to one of a plurality of patients includes a sterile patient supply tube, and structure for receiving pressurized fluid medium into the patient supply tube. One or more devices is provided for precluding backflow of material from the patient to the fluid medium receiving structure, for preventing contamination of the fluid medium receiving structure and/or for preventing cross-contamination between patients.

Abstract: An apparatus and method enabling the injection of fluid media into a plurality of patients in which there is provided a fluid supply source providing multiple doses, metering means for measuring the doses, pressurizing means to effect injection, contamination preventing means between fluid source and patient and, when desired, electronic control means to integrate operation of the apparatus and process.
