剂量指示器的改进或与其相关的改进
摘要：
本发明涉及用于压力致动的计量剂量吸入器(pMDI)装置的剂量指示器。在一个实施例中，所述剂量指示器包括：具有观察部分的底座元件；位于所述底座元件内的显示元件；可弹性变形的元件；和具有轴线的分度元件，所述分度元件沿其轴线从第一位置到第二位置的平移导致所述可弹性变形的元件在与所述分度元件的平移相同的方向上的变形，从而导致所述可弹性变形的元件的离所述轴线较近的部分相对于其离所述轴线较远的部分具有总体上更大的位移，所述可弹性变形的元件的所述部分在与所述分度元件的平移相同的方向上的所述位移引起所述显示元件相对于所述底座元件的所述观察部分从当前位置到随后位置的所述分度。
摘要（英）：

The present disclosure relates to a dose indicator for a pressure-actuated metered dose inhaler (pMDI) device. In an embodiment, the dose indicator comprises a chassis element having a viewing portion, a display element located within the chassis element, a resilient deformable element, and an indexing element having an axis, translation of the indexing element along its axis from a first position to a second position causing deformation of the resilient deformable element in the same direction as translation of the indexing element resulting in generally greater displacement of portions of the resilient deformable element nearer to the axis relative to portions thereof further from the axis, the displacement of the portions of the resilient deformable element in the same direction as translation of the indexing element inducing indexing of the display element from a current position to a subsequent position relative to the viewing portion of the chassis element.
