  • Publication number: 20150335821
    Abstract: A fluid path set for a fluid delivery system includes a tube coil that is designed to optimally position one or more volumes of a pharmaceutical within an ionization chamber to optimally measure and prepare a pharmaceutical dose for administration to a patient. The tube coil may be maintained in a desired dimensional geometry by means of a core structure around which the tube coil is positioned.

  • Patent number: 7079886
    Abstract: A fluid injection arrangement in the context of patient imaging systems, in which phases of contrast medium injection and flushing medium injection can be freely and selectably ordered as to make available to the operator and patient a vast array of possible protocols that has hitherto been essentially unattainable. The arrangement provides a programmable KVO phase and the ability to program a first phase of injection procedure as a flushing medium phase.

  • Publication number: 20040143185
    Abstract: A fluid injection system includes an injector comprising a drive mechanism and an illumination device, a fluid container operably associated with the drive mechanism, and a control device operably associated with the drive mechanism. The control device comprises a computer screen having at least one element affiliated with the illumination device. The illumination device and the at least one element emit light of the same color. Further, a method of operating an injector system providing visual stimuli corresponding to a programmed injection protocol includes perceiving visual stimuli provided by an injector or a control device of the injector system, recognizing a pattern provided by the visual stimuli, correlating the recognized pattern to the programmed injection protocol, determining whether the programmed injection protocol is a desired injection protocol, and initiating the programmed injection protocol, if it is determined that the programmed injection protocol is the desired injection protocol.

  • Publication number: 20040133161
    Abstract: A syringe for use with an injector includes a body having a rear end and a front end, a plunger movably disposed within the body, an attachment member associated with the body and adapted to releasably engage a syringe retaining mechanism of the injector regardless of the orientation of the syringe with respect to the injector, and an encoding device operable to provide syringe information to the injector.

  • Publication number: 20040133162
    Abstract: An injector for injecting fluid from a syringe mounted thereon includes a housing, a drive member at least partially disposed within the housing and operable to engage a plunger of the syringe, and a syringe retaining mechanism associated with the housing. The syringe retaining mechanism is adapted to releasably engage the syringe regardless of the orientation of the syringe with respect to the injector. Further, the retaining mechanism is preferably movable upon rotation of the syringe between a relaxed state, where the syringe is engaged by the retaining mechanism, and a tensioned state, where the syringe is released from the retaining mechanism.

  • Publication number: 20040133153
    Abstract: A syringe adapter for an injector and a method of adapting an injector to accept a syringe are provided. The syringe adapter preferably includes a rear mounting member adapted to engage a syringe retaining mechanism associated with the injector and a front mounting member adapted to engage a corresponding mounting member associated with a syringe to install the syringe on the injector.

  • Publication number: 20040133183
    Abstract: A method of preparing for an injection procedure preferably includes: mounting a syringe comprising a distal end and a plunger on an injector comprising a piston; sensing that the syringe is mounted on the injector; advancing the piston of the injector to engage the plunger of the syringe and to advance the plunger to the distal end thereof; and retracting the piston to retract the plunger and aspirate fluid into the syringe. Preferably, the method includes determining whether the syringe is an empty syringe, a preloaded syringe or a prefilled syringe.

  • Publication number: 20040116861
    Abstract: An injector system includes an injector and a syringe. The syringe preferably includes a body having a forward end and a rearward end, and a plunger movably disposed in the body. The injector preferably includes a housing and a piston movably disposed at least partially within the housing. The piston is adapted to drive the plunger of the syringe in a forward direction without a connective engagement therebetween to dispense fluid from the forward end of the body during an injection procedure, and to connectively engages the plunger to retract the plunger within the syringe.

  • Patent number: 6652489
    Abstract: Embodiments of an injector, syringe, syringe interface, and piston/plunger assembly for an injector (of contrast medium, for example) are described. Preferably, the syringe is adapted to engage a syringe interface mechanism such that the syringe may be connected to an injector without regard to any particular orientation of the syringe to the injector or to the piston/plunger assembly.

  • Publication number: 20030216643
    Abstract: A fluid injection arrangement, particularly involving a systematic fluid injection programming capability, in the context of patient imaging systems, in which phases of contrast medium injection and flushing medium injection can be freely and selectably ordered so as to make available to the operator and patient a vast array of possible protocols than has hitherto been essentially unattainable. Also contemplated is the use of a “hold” phase, involving an indefinite pause between phases of a protocol, in connection with such imaging systems. Further contemplated is the use of a “pause” phase in which a pause of fixed duration is pre-programmed into the protocols of MRI injector systems. Additionally contemplated is an internal stopwatch function operable to measure the duration of contrast medium propagation towards determining a scan delay, or for other purposes where such a function may be of benefit.
