  • Patent number: 10806852
    Abstract: An injector system for injecting fluid includes a syringe and an injector. The syringe includes a body and a plunger movably disposed within the body. The plunger has at least one flexible leg extending toward the rearward end of the body. The injector has a housing with a front plate, a drive member at least partially disposed within the housing and operable to engage the plunger, and a syringe release assembly operable to release the syringe. The syringe assembly includes a syringe release gear that forms an enclosure for receiving the syringe when the syringe is fully seated within the housing and a plunger release tube surrounding at least a portion of the drive member. The plunger release tube has a first end rotationally engaged with the syringe release gear. Rotation of the syringe release assembly releases the at least one flexible leg from the drive member.

  • Publication number: 20130211248
    Abstract: A bladder syringe for a fluid delivery system includes a cylindrical body, a cap-bladder assembly, a plunger element disposed in the cylindrical body, and a mounting assembly to secure the cap-bladder assembly to the cylindrical body. The cylindrical body has a distal end and a proximal end and defines a throughbore. The cap-bladder assembly is adapted for connection to the distal end of the cylindrical body, and includes a cap body and a bladder. The cap body defines an interior cavity and a distal discharge conduit and is adapted to engage the distal end of the cylindrical body. A disc-shaped bladder is disposed within the interior cavity and typically includes a central membrane portion. The plunger element is disposed in the throughbore of the cylindrical body and is vented to enable evacuation of the space between the plunger element and the cap-bladder assembly in the cylindrical body.
