    • A cartridge or injector for holding and mixing a medical product is provided herein including a tubular body having a cylindrical wall having first and second opposing ends. The wall includes inner and outer surfaces with the inner surface having a generally constant cross-section along at least a drug mixing area. A first stopper is slidably disposed within the wall between the first and second ends, the first stopper defining a liquid-tight seal with the inner surface. A second stopper is slidably disposed within the wall between the first stopper and the first end, the second stopper defining a liquid-tight seal with the inner surface. A flexible insert is disposed at or in proximity to the second end, the insert forming a liquid-tight seal with the wall, the insert being pierceable by a medical needle or other piercing instrument. A rigid retainer is fixed to the wall having an opening therein for providing access to the insert for piercing by a medical needle. The insert extends into the retainer and forms a liquid-tight seal across the opening. Advantageously, with the subject invention, a reconstitution assembly may be provided which has a sufficiently large distal opening during assembly which allows a dry component to be introduced into the device in a dry state.
    • 本文提供了用于保持和混合医疗产品的药筒或注射器,其包括具有圆柱形壁的管状体,其具有第一和第二相对端。 该壁包括内表面和外表面,其中内表面至少沿着药物混合区域具有大致恒定的横截面。 第一止动件可滑动地设置在第一和第二端之间的壁内,第一止动件限定与内表面的液密密封。 第二止动件可滑动地设置在第一止挡件和第一端之间的壁内,第二止动件限定与内表面的液密密封。 柔性插入件设置在第二端处或附近,插入件与壁形成液密密封,插入件可被医用针或其它穿刺器械刺穿。 刚性保持器固定到其上具有开口的壁上,用于提供通过医用针穿刺插入物的通路。 插入件延伸到保持器中并且跨越开口形成液密密封。 有利地,对于本发明,可以提供在组装期间具有足够大的远端开口的重构组件,其允许在干燥状态下将干燥部件引入装置。
