    • A dose counter (30) for a medicament delivery device comprises a rotatable indicator dial (7), and an index mechanism for incrementally rotating the indicator dial (7) when the medicament is dispensed. The index mechanism comprises an index element (8, 13) that selectively engages the indicator dial (7) to incrementally rotate the indicator dial (7), and further comprises a locking element (19, 14) that is moveable from a first position in which it locks rotation of the indicator dial (7) to a second unlocked position in which it allows rotation of the indicator dial (7) when the index element (8) engages the indicator dial (7). The dose counter (30) is preferably of an odometer type and comprises a further indicator dial (6) that rotate the other indicator dial (7) once a predetermined number of doses have been dispensed. In other aspects, the dose counter (30) includes a blanking element (23) to blank the indicator dial (6, 7) and/or a viewing window (24) when all of the doses have been dispensed. Yet another aspects relates to the use of a modified escapement mechanism (17, 10a, 10b) to convert the linear actuation of the device in rotary motion fo the dose counter dial (6).
    • 用于药物输送装置的剂量计数器(30)包括可旋转的指示盘(7)和用于在分配药剂时递增地旋转指示盘(7)的指示机构。 所述分度机构包括选择性地接合所述指示盘(7)以逐渐旋转所述指示盘(7)的指标元件(8,13),并且还包括锁定元件(19,14),所述锁定元件可从第一位置移动 其将指示盘(7)的旋转锁定到第二解锁位置,在第二解锁位置允许指示盘(7)接合指示盘(7)时,指示盘(7)旋转。 剂量计数器(30)优选为里程表型,并且包括另外的指示盘(6),其在分配了预定数量的剂量后旋转另一个指示盘(7)。 在其他方面,剂量计数器(30)包括当已经分配所有剂量时消隐指示盘(6,7)和/或观察窗(24)的消隐元件(23)。 另一方面涉及使用改进的擒纵机构(17,10a,10b)来在剂量计数器拨盘(6)的旋转运动中转换装置的线性致动。

    • A dose counter (20) for a medicament delivery device, in particular an inhaler, comprises two interengaged gears (5, 27) having different numbers of teeth (8, 9). One of the gears (27) is rotationally fixed and the gears (27, 5) are mounted so that actuation of medicament delivery device gyrates the engagement of one of the gears (5) around the other gear (27), and causes one of the gears (5) to rotate about its own axis with such rotation rotating a dose indicator (7). The gears may be crown gears (27, 5) with one mounted at an angle to the other, or an external gear (115/104) mounted eccentrically within an internal gear (102).
    • 用于药物输送装置,特别是吸入器的剂量计数器(20)包括具有不同齿数(8,9)的两个相互啮合的齿轮(5,27)。 齿轮(27)中的一个被旋转地固定,并且齿轮(27,5)被安装成使得药物输送装置的致动使得齿轮(5)中的一个齿轮(5)的啮合转动到另一个齿轮(27)周围,并使得 齿轮(5)围绕其自身的轴线旋转,旋转剂量指示器(7)。 齿轮可以是冠状齿轮(27,5),其一个以一个角度安装在另一个上,或者是偏心地安装在内齿轮(102)内的外齿轮(115/104)。
