    • The invention relates to a radiation shielded syringe assembly that includes a radiopharmaceutical syringe and a radiation shield (101) disposed about at least a portion of the syringe. The radiation shield may include a needle cap ejector (155) to assist a user in removing a needle cap (125) from a needle of the syringe (e.g., to perform an injection). For instance, in some embodiments, the user may press/push the needle cap ejector to detach the needle cap from the needle of the syringe. The radiation shield and needle cap ejector may be designed such that the needle cap may be removed from the needle of the syringe while the user is shielded from undesired exposure to radiation emitted from the radiopharmaceutical within the syringe.
    • 本发明涉及一种辐射屏蔽注射器组件,其包括放射性药物注射器和围绕注射器的至少一部分设置的辐射屏蔽(101)。 辐射屏蔽可以包括针帽喷射器(155),以帮助使用者从注射器的针头移除针帽(125)(例如进行注射)。 例如,在一些实施例中,用户可以按压/推动针帽喷射器以将针帽从注射器的针脱离。 辐射屏蔽和针帽喷射器可以被设计成使得当使用者被屏蔽以避免从注射器内的放射性药物发射的辐射的不期望的暴露时,针帽可以从针筒的针上移除。

    • An injector 20 that may be used to deliver radiographic contrast media and/or flushing solution into a patient's vascular system for the purposes such as obtaining enhanced diagnostic x-ray images. The injector includes the following features: (1) a syringe mount 26 for attachment of a syringe 28 to the injector 20; (2) display 34 and controls 90 for volume and flow rates; (3) automatic limiting of the operating pressure of the injector 20 as determined by the selection of a flow rate; (4) a syringe cradle 48 having a warming capability; (5) a purge/retract trigger 36 for control of the injection procedure having intuitive direction (i.e., forward for injecting, reverse for filing), non-contact control transmission through the housing of an injector 20 for an improved seal integrity, a speed lock, and/or the ability to change the concentration and/or flow rate of media or other fluid during an injection procedure; (6) a switch to determine when the drive ram 46 is in a “home” position; (7) a “soft” on/off power switch separate from the injector; and (8) a structure to prevent rotation of the drive ram 46 about its axis of symmetry 76. Additionally, the injector system includes software for the control of various components.
    • 注射器20,其可以用于将放射照相造影剂和/或冲洗溶液递送到患者的血管系统中,用于获得增强的诊断X射线图像。 注射器包括以下特征:(1)用于将注射器28附接到注射器20的注射器安装件26; (2)显示器34和控制器90的体积和流速; (3)通过选择流量来确定喷射器20的操作压力的自动限制; (4)具有加温能力的注射器支架48; (5)用于控制具有直观方向的注射程序(即,向前进行注射,反转以进行填充)的吹扫/收回扳机36,通过喷射器20的壳体的非接触式控制传动,以提高密封完整性,速度 锁定和/或在注射过程期间改变介质或其它流体的浓度和/或流速的能力; (6)用于确定驱动柱塞46何时处于“主”位置的开关; (7)与注射器分开的“软”开/关电源开关; 和(8)防止驱动压头46绕其对称轴线76旋转的结构。另外,喷射器系统包括用于控制各种部件的软件。
