    摘要： A frangible seal for a fluid path including a frangible seal member secured within a tube defining the fluid path. The frangible seal member having a tubular seal member and a stem extending from the tubular seal member which, upon bending back and forth, breaks away from the seal member thereby to rupture the tubular seal in the fluid path. The tubular seal member and stem are integrally formed of a non-PVC material. The tubular seal member will bond to PVC tubing during steam heating thereof. The tubular seal member and stem are constructed to provide uniform non-reclosable rupturing. The stem includes vanes with spurs that frictionally engage the inner walls of the tube to maintain separation of the stem and ruptured tubular seal member.

    摘要： A breakable seal is located within a housing. The housing includes a ribbed region of restricted diameter protruding from the wall into the bore. A breakable juncture in the seal joins the tip of a cannula member to the base of the cannula member. The leading portion of the tip is free of any projection that frictionally engages either the wall or the ribbed region. Thus, neither the wall nor the ribbed region contacts or constrains movement of the leading portion in the bore when the tip is broken from the base. The trailing portion of the tip carries at least one projection constructed to frictionally engage the ribbed region. The ribbed region constrains movement of the trailing portion through the bore when the tip is broken from the base. By rocking the cannula tip, the juncture can be broken and the cannula tip advanced to a secure position in the housing.

    摘要翻译： 可拆卸的密封件位于外壳内。 壳体包括从壁向孔中突出的有限直径的肋状区域。 密封件中的可断裂接合部将套管构件的尖端连接到套管构件的基部。 尖端的前导部分没有任何与壁或肋肋区域摩擦接合的凸起。 因此，当尖端从基部断开时，壁和肋肋区域都不接触或约束孔中的引导部分的运动。 尖端的尾部带有构造成摩擦接合肋状区域的至少一个突出部。 当尖端从基部断开时，肋状区域约束尾部穿过孔的运动。 通过摇动套管尖端，接合部可以被破坏并且套管尖端前进到壳体中的安全位置。
