Abstract
A reservoir for a nebulizer includes: a tank or bag containing multiple doses of a fluid to be nebulized, and an indicator device for counting or indicating a number of uses performed or still possible with the reservoir, where at least one of: the reservoir includes a connector for fluidically connecting the tank or bag with the nebulizer, the indicator device is actuated by moving the connector relative to the tank or bag, and the reservoir includes or forms an eccentrical linear guidance for a driving part for driving the indicator device.
