  • Publication number: 20220347408
    Abstract: The present invention relates to dose counting mechanisms for medicament inhaler devices, for example metered-dose inhaler (MDI) devices. In particular, the invention relates to a counter comprising a counting component (20,620), a locking element (46,646) for resisting movement of the counting component (20,620), and a distinct driving element (70,670) for driving movement of the counting component (20,620). The locking and driving elements are actuated by movement of a common element to move the locking element (46,646) out of engagement with the counting component (20,620) and to move the driving element (70,670). The driving element (70,670) applies a motive force to the counting component (20,620) before the locking element (46,646) fully disengages from the counting component (20,620).

  • Publication number: 20210386945
    Abstract: The present invention relates to inhaler devices (701), and in particular to devices provided with medicament carriers containing individual pockets or blisters of powdered medicament covered by a lidding sheet such as a lidding foil. A common actuator (710) is provided for controlling movement of an indexing system (712,714) for advancing/indexing a dose and an opening system (790,791) for opening a dose such that progression of the opening system (790,791) is disproportional to progression of the indexing system (712,714) during movement of the common actuator (710).

  • Publication number: 20210271955
    Abstract: A counting device for counting mechanical inputs comprising: a rotatably mounted first counting wheel arranged to rotate by a predetermined amount for every input that is to be counted; and, a second counting wheel in mechanical communication with the first counting wheel, and at least in part overlapping the first counting wheel, wherein the second counting wheel and/or the first counting wheel are at least in part transparent; whereby the mechanical communication between the first counting wheel and the second counting wheel comprises a rotation mechanism configured to drive the second counting wheel a predetermined amount when a predetermined number of inputs has been reached.
