Embodiment Construction

[0053] figure 1 and figure 2 Shown is a known nebulizer 1 for nebulizing a fluid 2, in particular a high potency pharmaceutical composition, medicament or the like, shown in an unstretched state ( figure 1 ) and stretched state ( figure 2 ). The nebulizer 1 is designed in particular as a portable inhaler and is preferably operated only mechanically and / or without propellant gas.

[0054] When atomizing a spray fluid 2 (preferably a liquid, more specifically a pharmaceutical composition), an aerosol 14 is formed or dispensed ( figure 1 ), the aerosol 14 can be inhaled or inhaled by the user. Usually, this inhalation is performed at least once a day, more specifically several times a day, preferably at set intervals, depending on the patient's complaint or the disease being suffered.

[0055] The nebulizer 1 is provided with or comprises a replaceable or insertable container 3 containing a fluid 2 . The container 3 thus forms a reservoir for the fluid 2 to be atomized fo...

Abstract

A nebulizer (1) is proposed which receives a container (3) with a fluid (2) and an indicator device (25). The indicator device stops further use of the container in a locked state when a predetermined number of uses has been reached or exceeded. In the locked state, a locking device (26) locks the nebulizer against rotation in a partially tensioned state and, thus, against further use. After replacement of the container including the indicator device, the nebulizer can be used again.

Description

technical field [0001] The invention relates to a nebulizer according to the preamble of claim 1 , 2 or 16 . Background technique [0002] WO2012 / 162305A1 discloses a nebulizer. A container is insertable into the housing of the nebulizer. The housing is closed by a lower housing part. By rotating the housing piece, the drive spring can be placed under tension and fluid can be drawn into the compression chamber of the pressure generator. Simultaneously, the container moves into the lower housing part during the stroke movement in the sprayer, and when stretched for the first time, the container can be pierced through its bottom by the piercing element in the lower housing part, allowing the Vent the container. After manual pressing of a button, the drive spring is released and the delivery tube is moved into the pressure chamber so that the fluid is under pressure due to the drive spring and is delivered or atomized as an aerosol through the nozzle to the oral piece with...
