Patent number: 7812322Abstract: The invention relates to the handling of radioactive material. For instance, a radiation shield of the invention may include a body having a cavity therein for receiving radioactive material. An opening to the cavity may be defined in the body. A base may be releasably attachable to the body (generally toward the opening) to at least partially enclose the radioactive material in the cavity. In the case that the radiation shield includes a plurality of interchangeable bases, one of the bases may have at least one of a shorter length and a lighter weight than another of the bases. The base(s) may be designed to enclose more than one size and/or shape of container in the cavity. The base(s) may include a hand grip to facilitate manual gripping of the radiation shield. The base(s) may include a guard to reduce exposure to radiation from manual handling of the radiation shield.Type: GrantFiled: July 26, 2006Date of Patent: October 12, 2010Assignee: Mallinckrodt Inc.Inventors: Gary S.

Publication number: 20100249704Abstract: A patency check protocol (150) for evaluating a patency check injection (156) is disclosed. The protocol (150) incorporates a pressure standard (152) (e.g., a pressure threshold; a target pressure curve). A pressure associated with the patency check injection is monitored (160) and compared against this pressure standard (164). If a first condition is identified (166) (e.g., if the pressure threshold is reached; if the monitored pressure deviates from the target pressure curve by more than a certain predetermined amount), one or more actions may be undertaken (168) (e.g., one or more notifications or alerts may be issued; the flow rate may be reduced for the patency check injection; the patency check injection may be suspended/terminated).Type: ApplicationFiled: November 19, 2008Publication date: September 30, 2010Inventor: Gary S.

Patent number: 7725168Abstract: A contrast media injection system includes 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: October 23, 2006Date of Patent: May 25, 2010Assignee: Mallinckrodt Inc.Inventors: Charles S.

Publication number: 20090149745Abstract: The present invention embodies a method and an injector adapted to incorporate this method, for keeping a patient's vein open during an intravenous contrast injector procedure without injecting a saline solution from a separate syringe. The injector includes a controller having a programmable software module to allow an operator to configure the injector to push some contrast media fluid through an injection site and then retract a plunger drive ram. A syringe is adapted to allow a patient's blood pressure to move the syringe plunger back towards its starting position, thus enabling a patient's blood to pass through the injection site. Alternatively, the syringe is adapted with an elastic plunger which as it enlarges and contracts facilitating fluid communication through the injection site. Additionally, the plunger drive ram can be adapted to gradually pull as well as push the plunger, thereby causing fluid to flow across the injection site.Type: ApplicationFiled: February 11, 2009Publication date: June 11, 2009Applicant: Liebel-Flarsheim CompanyInventors: Gary S.

Publication number: 20080210892Abstract: One or more aspects of the invention is directed to a radiation-shielding container for housing a radiopharmaceutical. A labeling system is attached to an exterior surface of the container. The labeling system is adapted to selectively convert from a first state to a second state. In the first state, the labeling system indicates a first condition of the radiopharmaceutical. For example, in the first state, the labeling system can show that the radiopharmaceutical is ready for administering. In the second state, the labeling system indicates a second condition of the radiopharmaceutical. For example, in the second state, the labeling system can show that the radiopharmaceutical has been administered, and/or that a syringe that was used to administer the radiopharmaceutical is now a biohazard.Type: ApplicationFiled: May 12, 2006Publication date: September 4, 2008Inventor: Gary S.
