    • The invention provides a drive mechanism for an autoinjector, configured to be coupled to a drug containing portion to form a complete autoinjector, the drive mechanism comprising: a housing (20); a drive means coupled to the housing, the drive means comprising a resilient member (22); a retaining means coupled to the housing, the retaining means (60) engaging the drive means in a first position to retain the resilient member in a deformed condition, and releasing the drive means in a second position; and a coupling means (24) for coupling with a drug containing portion (10). The drug containing portion retains the drive means in a second deformed condition when the retaining means is in the second position, the drive means storing enough energy in the second deformed condition to drive needle insertion and/or drug delivery.
    • 本发明提供了一种用于自动注射器的驱动机构,其配置为联接到药物容纳部分以形成完整的自动注射器,所述驱动机构包括:壳体(20); 联接到所述壳体的驱动装置,所述驱动装置包括弹性构件(22); 保持装置,联接到壳体,保持装置(60)在第一位置接合驱动装置,以将弹性构件保持在变形状态,并将驱动装置释放在第二位置; 以及用于与药物容纳部分(10)联接的联接装置(24)。 当保持装置处于第二位置时,药物容纳部分将驱动装置保持在第二变形状态,驱动装置在第二变形状态下存储足够的能量以驱动针插入和/或药物递送。
