INHALATION DEVICE SYSTEM WITH A COUNTING AND BLOCKING ASSEMBLY

The present invention provides an inhalation device system for the inhalative administration of a medically active liquid in nebulized form, the system comprising an inhalation device (20) and an exchangeable reservoir (30) for holding a plurality of doses of the medically active liquid, wherein one dose of the medically active liquid is dispensed from the inhalation device per actuation of the inhalation device system,wherein the inhalation device (20) comprises- a housing (21) having a receiving unit (23), the receiving unit having a connection unit (24) adapted to releasably and fluidically connect to a connection port (31) of the exchangeable reservoir (30), the receiving unit (24) being adapted to receive and fluidically connect to the exchangeable reservoir (30);- a nozzle (25) for the nebulization of the medically active liquid; and- a pumping unit (40) arranged within the housing (21) and adapted to be fluidically connected to the exchangeable reservoir (30) and to the nozzle (25) and being adapted to convey the medically active liquid (in a downstream direction) from the exchangeable reservoir (30) to the nozzle (25) and being adapted to move the exchangeable reservoir from a resting position to a primed position upon priming of the pumping unit;wherein the inhalation device system comprises a combined counting and blocking assembly comprising a counting unit for counting the number of actuations of the inhalation device system (following the insertion of the exchangeable reservoir into the inhalation device) and a blocking unit for blocking the movement of the exchangeable reservoir from the resting position to the primed position when a defined number of actuations (following the insertion of the exchangeable reservoir into the inhalation device) is reached,wherein the counting unit and the blocking unit are physically separated from each other when the exchangeable reservoir is in the resting position and adapted to interact with each other upon each movement of the exchangeable reservoir from the resting position to the primed position.
