  • Publication number: 20210232785
    Abstract: A reader system for reading information on at least one identification tag associated with a syringe connected to a fluid injector has a detector and a background screen spaced apart from the detector such that at least one of the at least one identification tags is positioned in an optical path between the detector and the background screen when the syringe is connected to the fluid injector. The reader system further has an illumination system configured for illuminating at least a portion of the background screen. The detector is configured for detecting and decoding the at least one identification tag. Methods for reading information on at least one identification tag associated with a syringe are also described.

  • Patent number: 10835680
    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.

  • Publication number: 20200139043
    Abstract: A plunger for use with a syringe has a plunger body with a proximal end, a distal end, and a circumferential sidewall extending between the proximal end and the distal end along a plunger longitudinal axis. The plunger further has at least one resiliently deflectable retaining member having a first segment attached to the plunger body and a second segment protruding toward the distal end of the plunger body and deflectable relative to the first segment. The plunger further has at least one actuation member associated with the at least one resiliently deflectable retaining member. The at least one actuation member interacts with a piston to deflect the at least one resiliently deflectable retaining member upon rotation of the plunger relative to the piston. The plunger is engageable with the piston regardless of a rotational orientation of the piston relative to the plunger.

  • Publication number: 20190231975
    Abstract: A fluid injector including an injector housing with at least one syringe port for receiving a syringe, and a locking mechanism associated with the at least one syringe port for securing the syringe within the at least one syringe port. The locking mechanism is configured for engaging at least one syringe retaining member of the syringe to releasably lock the syringe within the at least one syringe port. The at least one syringe retaining member rotationally guides the syringe into self-orienting alignment with the locking mechanism and is rotated by the locking mechanism into fully locked position after axial installation of the syringe into the at least one syringe port. The locking mechanism also axially ejects the syringe from the locking mechanism upon rotation of the syringe during removal.

  • Patent number: 9814871
    Abstract: A connector assembly for a fluid delivery system includes a conical body defining an interior cavity and a discharge outlet, the discharge outlet defining an internal passage in fluid communication with the interior cavity; and a connector removably attached to the discharge outlet. The connector includes a central body configured to be at least partially positioned within the internal passage of the discharge outlet, and an annular connector portion connected to the central body and configured to releasably engage an exterior of the discharge outlet, the central body defining an internal channel within the central body that is in fluid communication with the interior cavity of the conical body when the connector is attached to the discharge outlet.

  • Patent number: 7911209
    Abstract: A head coil for use with a parallel-imaging compatible MR system is disclosed, as is a method of making, and a neurovascular array (NVA) equipped with, same. The head coil includes conductive rings and rods configured to produce a plurality of electrically-adjacent primary resonant substructures about a birdcage-like structure, with each such primary resonant substructure including two rods neighboring each other and the short segment of each of the first and second rings interconnecting them. The primary resonant substructures are isolated from each other via a preamplifier decoupling scheme and an offset tuning scheme thereby enabling each primary resonant substructure (i) to receive an MR signal from tissue within its field of view and (ii) to be operatively couplable to one processing channel of the MR system for conveyance of the MR signal received thereby (iii) while being simultaneously decoupled from the other primary resonant substructures.
