  • Patent number: 9005098
    Abstract: Containers and methods for disposing unused pharmaceutical product are disclosed. Each container (100, 200, 300) may include a container body (104, 204, 304) with an internal chamber (116, 216, 316) for storing pharmaceutical product, along with a cover (124, 224, 324) for selectively limiting access to the chamber (116, 216, 316). An encapsulation component (128, 228, 328) may be selectively disposable within the chamber (116, 216, 316), and may be operable to encapsulate the pharmaceutical product within the container (100, 200, 300). For instance, the encapsulation component (128, 228, 328) may melt and/or flow into contact with the pharmaceutical product and thereafter solidify to encapsulate the pharmaceutical product. The encapsulation component (128, 228, 328) may melt and thereafter solidify between the cover (124, 224, 324) and shell (104, 204, 304) to limit removal of the cover (124, 224, 324) from the shell (104, 204, 304).

  • Patent number: 8993764
    Abstract: There is provided a method for the synthesis of norbuprenorphine, and ultimately buprenorphine, utilizing oripavine as the starting material. Conventional methods of producing buprenorphine utilize thebaine as the starting material, requiring an O-demethylation step, typically a low to moderate yield transformation. The present use of oripavine as a starting material does not require an O-demethylation step, since the oripavine molecule lacks an O-3 methyl group.

  • Patent number: 8983579
    Abstract: Systems and methods are presented for the visual indication of whether a power injector has discharged fluid from a power injector syringe in a previous medical procedure. In this regard, the systems and methods generally provide for a power injector and a syringe for use with the power injector. The syringe includes a visual indicator that moves between a first state and a second state at approximately the same time that the power injector discharges fluid from the syringe such that an operator may view the change in state.

  • Publication number: 20150025374
    Abstract: 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.

  • Patent number: 8932255
    Abstract: 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.

  • Patent number: 8926555
    Abstract: 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).

  • Patent number: 8925727
    Abstract: A transdermal patch container (10) that includes a container body (16), a first compartment (24), and a second compartment (28) is disclosed. One or more first transdermal patches (34) may be stored in the first compartment (24). One or more second transdermal patches (36) may be stored in the second compartment (28). The first transdermal patches (34) differ from the second transdermal patches (36) in at least one respect. A number of features may be incorporated to reduce the potential of being able to withdraw second transdermal patches (36) out of the second compartment (28). For instance, second transdermal patches (36) may be required to be directed through a slot (44) to enter a second compartment (28i). A flap (66) may be positioned below such a slot (58) within a second storage compartment (28ii). A plurality of vertically spaced or staggered flaps (96) may be positioned within a second storage compartment (28iv).

  • Publication number: 20150001102
    Abstract: Various embodiments of pharmaceutical product containers are disclosed. Each pharmaceutical product container includes a cap, a container body, and a locking mechanism. The locking mechanism is disposable from a locked state to an unlocked state at least when the cap is in a closed position relative to the container body (e.g., to define an enclosed space for pharmaceutical product). Once in the locked state and with the cap being in a closed position, the locking mechanism is unable to return to its unlocked state. Pharmaceutical product enclosed within the container with the locking mechanism being in its locked state may then be disposed of in any appropriate manner (e.g., discarded in the trash).
