    • A hemodialysis port (10) comprising a flexible housing member (25) defining one or more ports (3a,3b,3c). Each port (3a,3b,3c) has a selectively-permeable septum member (20a,20b,20c) disposed thereon to permit medical devices, for example, Huber needles (35), sheath and/or dilators to be inserted therein. At the interface between the housing (25) and the septum (20a,20b,20c), a spring member (21a,21b,21c) is provided to provide an axial force on the septum (20a,20b,20c) which seals the puncture created by the aforementioned medical devices. In one exemplary embodiment, the hemodialysis access port (10) of the present invention is comprised of a plurality of ports (3a,3b,3c) designed for multiple hemodialysis treatments over the life of the port. In other exemplary embodiments, the bottom (16a,16b,16c) of each port may comprise a needle stop insert formed of, for example, metal, titanium, stainless steel or ceramic.
    • 血液透析口(10)包括限定一个或多个端口(3a,3b,3c)的柔性外壳构件(25)。 每个端口(3a,3b,3c)具有设置在其上的选择性渗透的隔膜构件(20a,20b,20c),以允许例如Huber针(35),护套和/或扩张器插入其中的医疗装置。 在壳体(25)和隔膜(20a,20b,20c)之间的界面处设有弹簧构件(21a,21b,21c),以在隔膜(20a,20b,20c)上提供轴向力, 由上述医疗装置产生的穿刺。 在一个示例性实施例中,本发明的血液透析入口(10)由多个端口(3a,3b,3c)组成,其设计用于端口寿命期间的多次血液透析治疗。 在其他示例性实施例中,每个端口的底部(16a,16b,16c)可以包括由例如金属,钛,不锈钢或陶瓷形成的针止动插入件。
