    • An integrated catheter placement system for accurately placing a catheter within a patient's vasculature is disclosed. In one embodiment, the integrated system comprises a system console, a tip location sensor unit for temporary placement on the patient's chest, and an ultrasound probe. The tip location sensor senses a field produced by a stylet disposed in a lumen of the catheter when the catheter is disposed in the vasculature. The ultrasound probe ultrasonically images a portion of the vasculature prior to introduction of the catheter. ECG signal-based catheter tip guidance is included to enable guidance of the catheter tip to a desired position with respect to a node of the patient's heart. The stylet includes an electromagnetic coil that can be operably connected to the sensor unit and/or console through a sterile barrier without compromising the barrier. The stylet can also be wirelessly connected to the sensor unit and/or console.
    • 公开了一种用于将导管准确地放置在患者脉管系统内的集成导管放置系统。 在一个实施例中,集成系统包括系统控制台,用于临时放置在患者胸部上的尖端位置传感器单元和超声波探头。 当导管设置在脉管系统中时,尖端位置传感器感测由设置在导管的内腔中的探针产生的场。 在引入导管之前,超声探头超声波地对一部分脉管系统进行成像。 包括基于ECG信号的导管尖端引导以使导管尖端相对于患者心脏的节点能够引导到期望位置。 探针包括电磁线圈,其可以通过无菌屏障可操作地连接到传感器单元和/或控制台,而不会影响屏障。 探针也可以无线连接到传感器单元和/或控制台。

    • A safety needle device and positive flush mechanism for use with a vascular access port. In one embodiment, the combination needle assembly includes a needle, a body and a base, the body being collapsible to expunge fluid therefrom as the needle is withdrawn from a vascular access port. In another embodiment, the combination needle assembly includes a needle, a housing and a reservoir, the housing squeezing the reservoir to expunge fluid therefrom as the needle is withdrawn from the port. In another embodiment, the needle assembly includes a compression plate and balloon extension, the compression plate forcing fluid out of the balloon extension as the needle is withdrawn from the port. In all embodiments, the needle assembly is configured to provide a positive flush to overcome negative pressures in the vascular access port, while also providing a locking mechanism to prevent accidental needle sticks.
    • 用于血管通路口的安全针装置和正冲洗机构。 在一个实施例中,组合针组件包括针,主体和基部,当针从血管进入端口中取出时,身体可折叠以从其中清除流体。 在另一个实施例中,组合针组件包括针,壳体和容器,当针从口中取出时,壳体挤压容器以从其中清除流体。 在另一个实施例中,针组件包括压缩板和气囊延伸部,当针从端口中取出时,压缩板迫使流体从气囊延伸部分流出。 在所有实施例中,针组件被配置为提供正冲洗以克服血管进入口中的负压,同时还提供锁定机构以防止意外的针刺。
