A system with a nebulizer as well as a container with a fluid and an indicator device for such a nebulizer are proposed. A check scheme is used for indicating the number of containers already used with the nebulizer or which still can be used with the nebulizer. The indicator device indicates the number of uses performed or still possible with the current container. The indicator device is adapted to let stepwise appear a color sequence and/or replacement symbol when approaching a predetermined number of uses with the container. Further, the indicator device can show markings in braille.
