  • 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: 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: 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: 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: 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.
