    • The present invention provides a number of pumping systems and injection systems particularly useful for injecting a liquid medium into a patient. In general, the pumping systems comprise a removable pumping unit. The removable pumping unit includes means for pressurizing the liquid medium via the rotational displacement of the liquid medium. The present invention also provides a pumping system comprising a pumping unit for pressurizing the liquid medium and a feedback-controlled drive means in connection with the pumping unit for providing a controlled powered drive to the pumping unit. The pumping system further comprises a flow meter for measuring the flow rate of the pressurized liquid medium exiting the pumping system and control means in communicative connection with the drive means for providing a control signal to control the powered drive provided to the pumping unit. The control means is suitable to receive a feedback signal from the flow meter corresponding to the flow rate of the pressurized liquid medium exiting the pumping unit. The control signal provided to the drive means is a function of the feedback signal.
    • 本发明提供了一些特别可用于将液体介质注射到患者体内的泵送系统和注射系统。 通常,泵送系统包括可拆卸的泵送单元。 可移除泵送单元包括用于通过液体介质的旋转位移对液体介质进行加压的装置。 本发明还提供了一种泵送系统,其包括用于对液体介质进行加压的泵送单元和与泵送单元相连的反馈控制的驱动装置,用于向泵送单元提供受控的动力驱动。 泵送系统还包括用于测量离开泵送系统的加压液体介质的流量的流量计和与驱动装置通信连接的控制装置,用于提供控制信号以控制提供给泵送单元的动力驱动。 控制装置适于从流量计接收对应于离开泵送单元的加压液体介质的流量的反馈信号。 提供给驱动装置的控制信号是反馈信号的函数。

    • An injection apparatus for use with a syringe is provided. The injection apparatus includes an injector and a pressure jacket assembly. The injector preferably includes a housing defining a front opening and a drive piston extendible through the front opening for imparting motive force to a plunger disposed within the syringe. The pressure jacket assembly preferably includes a jacket cylinder having a rear end coupled to the injector housing and an open front end for receiving the syringe therethrough, a support member having a rear end pivotally coupled to the injector housing and a front end, and a front member pivotally coupled to the front end of the support member. Preferably, the front member is pivotable between a closed position for retaining the syringe within the jacket cylinder and an open position for allowing the syringe to be inserted into and removed from the front end of the jacket cylinder.
    • 提供了一种用于注射器的注射装置。 注射装置包括注射器和压力套组合件。 喷射器优选地包括限定前开口的壳体和可延伸穿过前开口的驱动活塞,用于向设置在注射器内的柱塞赋予动力。 压力套组件优选地包括护套筒,其具有联接到注射器壳体的后端和用于接收穿过其的注射器的敞开的前端,具有可枢转地联接到注射器壳体的后端和前端的支撑构件,以及前端 构件枢转地联接到支撑构件的前端。 优选地,前部构件可以在用于将注射器保持在套筒内的关闭位置和用于允许注射器插入到护套筒的前端中并从套筒筒的前端移除的打开位置之间枢转。
