The fluid injector system includes a source of injection fluid, a pump device, and a fluid path set in fluid connection with the source of injection fluid and the pump device. The fluid path set includes a drip chamber including an elongated body having a raised projection from substantially a top end to substantially a bottom end, the elongated body configured to receive and contain the injection fluid. A fluid level sensing mechanism is operably associated with a fluid control device, and includes a support for the drip chamber body, wherein the support is adapted such that the raised projection is in operational contact with a fluid level sensor associated with the support. The fluid level sensing mechanism is operable to transmit ultrasonic or light energy through the raised projection to be sensed by the fluid level sensor for sensing the injection fluid level in the drip chamber.

Drip chamber and fluid level sensing mechanism for a fluid delivery system

A method of coordinating an imaging procedure and an injection procedure, the method comprising the steps of providing an injector system having first and second pressurizing units for pressurizing a contrast medium and a diluent for injection into a patient; providing an imaging system for producing an image of an internal region of the patient from a signal resulting from energy applied to the patient; and providing a data interface interconnecting the injector and imaging systems for enabling exchange of digital information therebetween such that the digital information transmitted between the systems is usable to enable closed loop control of at least one of the injection and the imaging procedures during which the contrast medium and the diluent injected into the patient is adjustable so as to achieve a desired level of enhancement within the internal region of the patient of which the images are acquired during the imaging procedure.

Methods of coordinating an imaging procedure and an injection procedure

An interface unit enables communication with an injector system that is used for pressurizing a fluid medium for injection into a patient during an injection procedure. The interface unit includes a processor and a storage unit. The processor controls operation of the interface unit and enables exchange of digital information between the interface unit and the injector system. The storage unit, under control of the processor, records the digital information gathered from the injector system during communication therewith. The digital information includes at least injection profile, history and dose data pertaining to the injection procedure. The processor enables at least the injection profile, history and dose data of the digital information recorded within the storage unit of the interface unit to be communicable to at least one of an imaging system linked thereto and an external device linked thereto.

Interface unit for use with injectors and imaging systems and related devices

A system for producing a contrast-enhanced medical image of a patient includes a source of a contrast or enhancement medium, a pressurizing unit in fluid connection with the source of contrast or enhancement medium, an energy source operable to apply energy to a region of the patient, an imaging unit providing a visual display of an internal view of the patient based upon a signal resulting from the energy applied to the region of the patient, and a control unit. In an embodiment, the signal is affected by a condition of the contrast or enhancement medium in the patient. To control the procedures, the control unit adjusts the condition of the contrast or enhancement medium in the patient based upon the signal. A communication interface preferably enables information between an injector subsystem and an imaging subsystem.
