Patent number: 8288744Abstract: In one characterization, the present invention relates to a radiation-shielding assembly for holding a container having a radioactive material disposed therein. The assembly may, at least in one regard, be referred to as an elution shield and/or a dispensing shield. The assembly includes a body at least partially defining a cavity. There is at least one opening through the body into the cavity. The assembly may include a cap that at least generally hinders escape of radiation from the assembly through the opening. The cap may be releasably attached to the body in one orientation and may establish non-attached engagement with the body in another orientation. The assembly may include an adjustable spacer system for adapting the assembly for use with containers having different heights.Type: GrantFiled: May 13, 2011Date of Patent: October 16, 2012Assignee: Mallinckrodt LLCInventors: Frank M.

Patent number: 8282595Abstract: A contrast media injection system detects the absolute position of the syringe ram using a non-contact sensor. A series of magnets and Hall-Effect sensors may be used or an opto-reflective system. Illuminated knobs that are connected to the drive mechanism for the syringe ram rotate with the drive and provide visual feedback on operation through the illumination. Analog Hall-Effect sensors are used to determine the presence or absence of magnets that identify the type of faceplate being used. The faceplates include control electronics, connected to the powerhead through connectors, which may be interchangeably used by the two faceplates. The faceplate electronics include detectors for automatically detecting the capacity of pre-filled syringes.Type: GrantFiled: January 14, 2008Date of Patent: October 9, 2012Assignee: Mallinckrodt LLCInventor: Gary S. Wagner

Patent number: 8012124Abstract: Various sealing structures are used in a front-loading injector, for preventing leakage of spilled fluid from an external surface of a syringe into the vicinity of the drive ram. For example, a sealing gasket may be incorporated into the front face of the injector housing, for mating to the rearward circular edge of the cylindrical body of a syringe. Alternatively, sealing and locking functions may be performed by a single structure on the rearward end of the syringe. Further, leakage may be prevented by including a non-planar sealing flange on the syringe, positioned on the syringe forward of the locking structure, or by a two-piece structure, including a syringe and a separate leakage stopping washer for surrounding the syringe to halt the flow of fluid along the exterior of the syringe. As part of this aspect, or as an independent feature, the syringe may include an annularly discontinuous flange forward of the locking structure, for providing mechanical support for the syringe against the injector.Type: GrantFiled: February 21, 2008Date of Patent: September 6, 2011Assignee: Liebel-Flarsheim Company LLCInventors: Frank M. Fago, Robert Ziemba, Gary S. Wagner

Publication number: 20110201867Abstract: A radiopharmaceutical containment or pig, in certain embodiments, may include a plurality of cavities or chambers to accommodate a syringe and other medical devices. For example, a syringe may be housed in a first chamber of the radiopharmaceutical containment, and a tube coupled to the syringe may be housed in a second chamber and extractable via a passage in the radiopharmaceutical containment. In some embodiments, a user may extract a radiopharmaceutical from the radiopharmaceutical containment without having to remove the syringe from the containment. The radiopharmaceutical containment may include radiation shielding, an aperture to enable a ram of a power injector to engage or interact with a syringe inside the containment, a movable shutter over the aperture, various labels, and/or an integral storage compartment.Type: ApplicationFiled: September 24, 2009Publication date: August 18, 2011Inventor: Gary S.

Publication number: 20100274182Abstract: A flow rate assessment protocol (140) that may be utilized by a power injector (10) is disclosed. This flow rate assessment protocol (140) monitors a flow rate (156) during execution of a medical fluid delivery protocol (154). This monitored flow rate is compared with a target flow rate (158). A comparative output of this monitored flow rate and target flow rate is displayed (160), for instance on a graphical user interface (11).Type: ApplicationFiled: November 19, 2008Publication date: October 28, 2010Inventors: Sean B.
