    • A medicament delivery device (1) comprises a housing (15), a telescopic piston rod assembly (12) for driving a bung (20) of a medicament container (9), and a drive mechanism (17) for the telescopic piston rod assembly. The telescopic piston rod assembly (12) has an input drive (23) telescopically coupled to a plunger (55) for driving the bung (20) via an intermediate coupling. The intermediate coupling comprises first and second cylinders (45, 49) telescopically coupled to one another. The plunger (55) is telescopically coupled to one of the first and second cylinders (45, 49) and the input drive (23) is telescopically coupled to the other cylinder. A key (14) is provided for restraining rotation of the plunger (55) relative to the housing (15) so that as the drive mechanism (17) drives the input drive, the plunger, first and second members and input drive telescopically expand or retract with respect to one another.
    • 药物输送装置(1)包括壳体(15),用于驱动药物容器(9)的栓(20)的伸缩活塞杆组件(12)和用于伸缩活塞杆组件的驱动机构(17) 。 伸缩活塞杆组件(12)具有可伸缩地联接到柱塞(55)的输入驱动器(23),用于通过中间联接器驱动栓(20)。 中间联接器包括彼此伸缩联接的第一和第二气缸(45,49)。 柱塞(55)可伸缩地联接到第一和第二气缸(45,49)中的一个,并且输入驱动器(23)可伸缩地联接到另一个气缸。 提供了一种用于限制柱塞(55)相对于壳体(15)的旋转的键(14),使得当驱动机构(17)驱动输入驱动器时,柱塞,第一和第二构件和输入驱动器可伸缩地扩展或 相对于彼此缩回。
