    • A check valve in particular for medical applications has a first hose connecting casing and a second hose connecting casing and a membrane disk configured between the two hose connecting casings. The membrane disk is made of a resilient material and cooperates with an annular valve seat. The membrane disk is fitted radially outside the valves seat with apertures leading to a discharge space. The wall of the second hose connecting casing is opposite the apertures and fitted with a surface curved away from the membrane toward the discharge channel. The discharge channel is fitted with an intake mouth in the wall, and conically tapers within a transition segment toward the intake mouth. Recesses communicating with the discharge space are fitted into the transition segment and are dimensioned in a way to substantially compensate the different flow cross-sections between the intake mouth and the discharge channel.
    • 特别是用于医疗应用的止回阀具有第一软管连接壳体和第二软管连接壳体以及配置在两个软管连接壳体之间的膜盘。 膜盘由弹性材料制成,并与环形阀座配合。 膜片径向地安装在阀座之外,孔径通向放电空间。 第二软管连接壳体的壁与孔相对,并且装配有远离膜朝向排出通道弯曲的表面。 排放通道在壁上装有进气口,并且锥形在过渡段内朝向进气口锥形。 与放电空间连通的凹部装配到过渡段中,并且其尺寸设置为基本上补偿进气口和排出通道之间的不同流动横截面。

    • A device for removing a filter element from a retrieval catheter is provided. The device includes a core member which has a diameter corresponding to a filter element; a handle at a proximal end of the core member; and an engagement portion, formed at a distal end of the core member, for engaging the filter element. Alternatively, the device includes a first member including a core wire, a core wire handle; and an engagement portion, and a second member including a hypotube; and a hypotube handle, wherein the core wire is moveably disposed coaxially inside of the hypotube, such that when a distal end of the core wire handle is pressed against a proximal end of the hypotube handle, the engagement portion of the first member extends beyond a distal end of the hypotube. Alternatively, the device includes a partially cylindrical member, a handle; and at least one blade.
