摘要：
A dose counter (150) for a metered dose inhaler (100), the metered dose inhaler a housing of action and a cartridge (300) with an actuating valve at the end of the cartridge valve, the cartridge configured to be accommodated in the housing acting and move from a rest position to an activation position in which the valve is pressed against a bottom of the housing showing the dose counter comprising: a winder unit (500) having at least a first and second member actuator therein, the actuator unit being configured to interact with the cartridge when the cartridge moves in the longitudinal direction of the resting position to the activation position A circuit assembly (400) having a substrate with at least a first and second switch (406, 408) therein, the first and second circuits being configured to interact with the first and second drive member (518, 520) when the cartridge moves from the rest position to the actuated position so that the first actuator member actuates the first switch and the second actuator member actuates the second switch when the cartridge reaches the second longitudinal position which is different from the first longitudinal position during movement of the cartridge the rest position to the activation position Wherein the first and second drive member are configured to move from a first position to a second position 20 to activate the first and second switch when the cartridge moves in the longitudinal direction and the circuit assembly further comprises a counter circuit (404) that is configured to receive a signal from the first and second switch indicating at least one first time when the switch is activated by the first actuator member and a second time when the second switch is activated by the second actuator member, and to determine when the metered dose inhaler is activated in response to the first and second time, wherein the counter circuit (404) is designed to determine whether the metered dose inhaler is activated when there is a ti
