摘要:
A practically diffusion-tight container which is capable of being stored over long periods of time and with which the liquid does not come into contact with the ambient air is required for withdrawing a liquid in a dosed manner out of the same over a duration of several months. The inventive cartridge is a container which is comprised of three shells and which can consist of a collapsible bag containing the liquid, of a dimensionally stabile container, and of a stiff metal shell. The cartridge can be detachably connected to a withdrawing device. The cartridge can be provided with a micro-opening with which the time for the pressure compensation between the cartridge and the surroundings can be adjusted. The cartridge is suited for aqueous and alcoholic liquids which contain a pharmacologically active ingredient. The liquid in the cartridge is protected against external influences. The cartridge can be used in an atomizer for generating an aerosol which can be inhaled and which is provided for treating illnesses.

The invention relates to a locking-tensioning mechanism for a miniaturised high-pressure generator, the construction of said mechanism being configured only for the volume of liquid that is to be delivered. The volume that is to be delivered by said high-pressure generator can be retroactively modified by adjusting the stop of the elastic part. The basic components of the locking-tensioning mechanism and the high-pressure generator remain unchanged. At least one additional component is provided as a spacer in the form of intermediate rings, stepped pulleys, adjusting screws or adjusting nuts. A continuous helical-sliding gear or a helical-sliding gear that can be adjusted in steps can also be used to adjust a stop of the elastic part. The volume to be delivered can be modified either discontinuously or continuously during the assembly of the locking-tensioning mechanism, or prior to the use of the high-pressure generator, or during the use of said high-pressure generator. The locking-tensioning mechanism for a miniaturised high-pressure generator with a reproducibly adjustable volume, lying in the microlitre range, of liquid to be delivered can be used, for example, in a high-pressure atomiser for producing an aerosol that can be inhaled, or in a needle-free injector for injecting a volume of liquid into animal or vegetable tissue.
摘要:
A nebuliser (1) for a fluid, particularly for medical aerosol treatment is proposed. To allow easier operation and confer improved operational reliability a sealed container (3) holding the fluid is already arranged in the nebuliser when it is supplied and the nebuliser is constructed so that the container is opened inside the nebuliser before or during the first use of the nebuliser. Alternatively, or in addition, the nebuliser is constructed so that the container cannot be replaced and in particular cannot be removed.

The invention relates to an atomizer (1) comprising an insertable container (3) and a monitoring device (20) for counting actuations of the atomizer. The monitoring device is arranged in a detachable housing part (15) and directly records movements of the container during an atomizing step, an air flow in the region of a mouth piece and/or the production of an aerosol, in order to detect an actual discharge of fluid and to count the number of actuations of the atomizer. Preferably, the respective moment in time when the atomizer is actuated is detected and stored in order to improve monitoring and user guidance.

The invention relates to an atomiser (1) for a fluid and a container (3) which can be inserted into the atomiser with the fluid. In order to improve safety during use, the atomiser comprises a first coding means (24), and a second coding means (25) is associated with the container, such that the container can only be used with a suitable code in the atomiser or can be used therewith. Preferably, the code associated with the container comprises a specific identification for the fluid disposed in the container.
摘要:
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 indi¬ cates 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 ap¬ proaching a predetermined number of uses with the container. Further, the indicator device can show markings in braille.
