    • A mixing device comprises a first cylinder (10) containing a particulate or powdered component (11) and having a closed first end (13, 14) and an opposite second end which is closed by a piston-like venting and filtering assembly (12, 15). The device also comprises a second cylinder (18) containing the liquid component (19) and having a closed end (20, 22) and an opposite open end sealingly receiving the closed end of the first cylinder (10) therein in a piston-like manner. Means (14) are provided for communicating the inner space of the first and second cylinders (10, 18) through the closed end (13, 14) of the first cylinder (10), when the first cylinder is forced into the second cylinder, whereby liquid from the first cylinder is injected into interstices defined between the particulate component contained in the first cylinder for providing a paste-like material. The communicating means is preferably formed by a breakable membrane (14). The venting and filtering assembly (12, 15) may be used as a piston for discharging the paste-like mixture made from the first cylinder (10). The mixing device is preferably used for mixing components so as to form a bone cement.
    • 混合装置包括含有颗粒或粉末状组分(11)并具有封闭的第一端(13,14)的第一气缸(10)和由活塞式排气和过滤组件(12)闭合的相对的第二端, 15)。 该装置还包括容纳液体部件(19)并具有闭合端(20,22)的第二气缸(18),并且相对的开口端以活塞状密封地容纳第一气缸(10)的封闭端 方式。 提供装置(14),当第一气缸被迫进入第二气缸时,通过第一气缸(10)的封闭端(13,14)将第一和第二气缸(10,18)的内部空间连通, 从而将来自第一气缸的液体注入到包含在第一气缸中的颗粒组分之间限定的间隙中,以提供糊状材料。 连通装置优选由可破坏膜(14)形成。 排气和过滤组件(12,15)可以用作用于排出由第一气缸(10)制成的糊状混合物的活塞。 混合装置优选用于混合组分以形成骨粘固剂。
