Abstract

See full text

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.
