在药剂分配器中使用的计数器
摘要：
本发明提供一种用于药剂分配器的剂量计数器(1)。该计数器包括第一计数轮(20)，其被配置为环绕第一旋转轴旋转，该第一计数轮包括一组环状配置于其上的主驱动齿(24)，用以驱动第一计数轮环绕第一旋转轴旋转；第二计数轮(30)，其被配置为环绕第一旋转轴旋转，该第二计数轮包括一组环状配置于其上的二级驱动齿(34)；以及传动轮(40)，其被配置为环绕偏离于第一旋转轴的第二旋转轴旋转，该传动轮包括一组环状配置于其上的传动齿(44)，该传动齿组与第二计数轮的二级驱动齿组相啮合，从而使得传动轮的旋转运动引发第二计数轮的旋转运动。第一计数轮进一步包括一个固定的分度齿(28)，其被配置为间歇性的与传动轮的传动齿相啮合，从而使得只有在间歇性啮合发生时，第一计数轮的旋转运动才引发传动轮的旋转运动。
摘要（英）：

There is provided a dose counter (1) for use with a medicament dispenser. The dose counter comprises a first count wheel (20) arranged to rotate about a first axis of rotation, the first count wheel including a set of primary drive teeth (24) arranged annularly thereon for drivable rotation of the first count wheel about the first axis of rotation; a second count wheel (30) arranged to rotate about the first axis of rotation, the second count wheel including a set of secondary drive teeth (34) arranged annularly thereon; and a kick wheel (40) arranged to rotate about a second axis of rotationoffset from the first axis of rotation, the kick wheel including a set of kick teeth (44) arranged annularly thereon and in meshed relationship with the set of secondary drive teeth of the second count wheel such that rotary motion of the kick wheel results in rotary motion of the second count wheel. The first count wheel further includes a fixed index tooth (28) arranged for intermittent meshingwith the kick teeth of the kick wheel such that rotary motion of the kick wheel results from rotary motion of the first count wheel only when the intermittent meshing occurs.
