Abstract
A nebulizer for nebulizing a fluid is proposed. The nebulizer includes an indicator device with a rotatable indicator element for counting or indicating a number of actuations performed or still possible with the nebulizer and a rotatable shaft which rotatably drives the indicator element. The indicator device is non-detachably attached to the shaft and/or to an inner part of the nebulizer. The nebulizer may further include a positioning device that keeps the shaft in a defined rotational position and/or blocks the shaft from rotating backwards.
Claims18
A nebulizer for nebulizing a fluid, comprising:
- a container with a container housing containing the fluid,
- an inner part in which the container is received,
- a holder moveably positioned within the inner part for holding the container,
- a detachable housing part which is detachable from the inner part,
- an indicator device with a rotatable indicator element for counting or indicating a number of actuations performed or still possible with the nebulizer, and a rotatable shaft which is configured to rotatably drive the indicator element,
- wherein the indicator device comprises an indicator housing,
- wherein the indicator device is separate from the container and wherein the indicator housing is non-detachably attached to an end of the inner part, and
- wherein the detachable housing part is configured to receive the end of the inner part and the indicator device such that the detachable housing part, the holder, and the inner part cooperate to enclose the container during use and the detachable housing part encircles the indicator device.
A nebulizer for nebulizing a fluid, comprising:
- a container with a container housing containing the fluid,
- an inner part in which the container is received,

- wherein the detachable housing part is configured to receive the end of the inner part and the indicator device such that detachable housing part, the holder, and the inner part cooperate to enclose the container during use and the detachable housing part encircles the indicator device.
A nebulizer for nebulizing a fluid, comprising:
- a container with a container housing containing the fluid,
- the container being configured to execute a stroke movement relative to an indicator device when the nebulizer is actuated,
- an inner part in which the container is received,
- a holder moveably positioned within the inner part for holding the container,
- a detachable housing part which is detachable from the inner part,
- the indicator device having a rotatable indicator element for counting or indicating a number of actuations performed or still possible with the nebulizer, and
- a rotatable shaft which is configured to rotatably drive the indicator element,
- wherein the indicator device comprises an indicator housing,
- wherein the indicator device is separate from the container and wherein the indicator housing is non-detachably attached to an end of the inner part,
- wherein the detachable housing part is configured to receive the free end of the inner part and the indicator device such that detachable housing part, the holder, and the inner part cooperate to enclose the container during use and the detachable housing part encircles the indicator device, and
- wherein a height of the indicator device or the indicator housing of the indicator device corresponds at least essentially to the length of the stroke movement.
