    摘要： 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assembly includes a needle, a body and a base, the body being collapsible to expunge fluid therefrom as the needle is withdrawn from a vascular access port.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a needle, a housing and a reservoir, the housing squeezing the reservoir to expunge fluid therefrom as the needle is withdrawn from the port.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plate and balloon extension, the compression plate forcing fluid out of the balloon extension as the needle is withdrawn from the port.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.

    摘要翻译： 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。

    摘要： An access port for subcutaneous implantation is disclosed. Such an access port may comprise a body for capturing a septum for repeatedly inserting a needle into a cavity defined within the body. Further, the access port may include at least one feature structured and configured for identification of the access port subsequent to subcutaneous implantation. Methods of identifying a subcutaneously implanted access port are also disclosed. For example, a subcutaneously implanted access port may be provided and at least one feature of the subcutaneously implanted access port may be perceived. Further, the subcutaneously implanted access port may be identified in response to perceiving the at least one feature. In one embodiment, an identification feature is engraved or otherwise defined by the access port, so as to be visible after implantation via x-ray imaging technology.

Methods of identifying a subcutaneously implanted access port are also disclosed. For example, a subcutaneously implanted access port may be provided and at least one feature of the subcutaneously implanted access port may be perceived.
