    • Disclosed herein is a dose counter (18) for counting doses of medicament dispensed by or remaining in a metered-dose inhaler. The dose counter comprises a rotatably mounted first gear wheel (30) having a circular arrangement of ratchet teeth and a display (44) coupled to the first gear wheel, the display having a visible array of dose counting indicia indexable in response to rotary motion of the first gear wheel. The dose counter further comprises an actuator mechanism (20,22,24,26) having a first ratchet drive pawl for engaging the ratchet teeth of the first gear wheel in response to the dispensation of a medicament dose, and a second ratchet drive pawl for engaging the ratchet teeth of a gear wheel coupled to the display. The actuator mechanism is configured such that, in use of the dose counter for counting a dispensed dose, a first ratchet tooth of the first gear wheel is engaged and rotatably driven by the first ratchet drive pawl and then a second ratchet tooth of the gear wheel coupled to the display is engaged and rotatably driven by the second ratchet drive pawl. The gear wheel arranged for engagement by the second ratchet drive pawl is a different gear wheel to the first gear wheel.
    • 本文公开了一种剂量计数器(18),用于对由计量吸入器分配或保留在其中的药剂的剂量进行计数。 剂量计数器包括可旋转地安装的具有棘轮齿的圆形布置的第一齿轮(30)和联接到第一齿轮的显示器(44),显示器具有响应于旋转运动而可索引的剂量计数标记的可见阵列 第一个齿轮。 所述剂量计数器还包括致动器机构(20,22,24,26),所述致动器机构具有第一棘轮驱动棘爪和第二棘轮驱动棘爪,所述第一棘轮驱动棘爪用于响应于药剂剂量的分配而接合所述第一齿轮的所述棘轮齿, 接合连接到显示器的齿轮的棘齿。 致动器机构被构造成使得在使用剂量计数器来计数分配剂量时,第一齿轮的第一棘齿被第一棘轮驱动爪接合并被第一棘轮驱动爪旋转驱动,然后齿轮的第二棘齿 与显示器耦合的第二棘轮驱动棘爪被接合并由第二棘轮驱动棘爪可旋转地驱动。 布置成由第二棘轮驱动爪接合的齿轮是与第一齿轮不同的齿轮。

    • A bi-directional snap-action register mechanism for an odometer-type mechanical register display. The mechanism includes at lease one register display wheel (61) and a bi-directional cam (17) mounted coaxially along a common shaft (1) with the register display wheel. The bi-directional cam (17) engages a helical groove (15) formed along the shaft to allow lateral displacement of the bi-directional cam in a direction parallel to a rotational axis of the shaft (1). A pin (i4) is biased by a spring into contact with the bi-directional cam. Rotation of the shaft causes the bi-directional cam to be moved with respect to the pin. The cam abruptly rotates through a predetermined angular distance when the point of contact of the biased pin with the cam moved from a smooth portion to a step transition portion of the cam. The abrupt rotation of the cam is communicated to the register display wheel to cause a new display position to be moved into view.
    • 一种用于里程表型机械寄存器显示的双向快动记录机构。 该机构包括至少一个寄存器显示轮(61)和双向凸轮(17),该凸轮同轴地沿着具有对位显示轮的公共轴(1)安装。 双向凸轮(17)接合沿着轴形成的螺旋槽(15),以允许双向凸轮在平行于轴(1)的旋转轴线的方向上的横向位移。 销(i4)被弹簧偏压以与双向凸轮接触。 轴的旋转导致双向凸轮相对于销移动。 当偏置销与凸轮的接触点从平滑部分移动到凸轮的台阶过渡部分时,凸轮突然旋转预定的角距离。 凸轮的突然旋转传递到定位显示轮,以使新的显示位置移动到视野中。
