摘要:
A device, cartridge and method for dispensing a liquid, preferably a drug, are proposed. The liquid is pressurized in a cartridge to a first lower pressure and, then, pressurized in doses by a pump to a second higher pressure. A valve arranged between the cartridge and the pump is normally closed and/or opened only temporarily. Thus, evaporation and dripping of liquid can be avoided or minimized.

A nebulizer is proposed which comprises an insertable container and a securing means for holding the container in the nebulizer such that the container can move back and forth but can not be separated. The securing means is formed by a metal unitary part. The securing means forms a transportation lock for holding the container unmovable in the housing in a delivery state of the nebulizer. The securing means forms a cage which encompasses the container.

A nebulizer is proposed which comprises an insertable container and a counter device for counting operations of the nebulizer. The nebulizer can be opened for replacing the container. The counter devices blocks opening of the nebulizer until a predetermined number for operations has been reached.
摘要:
A nebulizer for a fluid having a pressure generator for conveying and nebulizing the fluid, particularly in the form of an inhaler, is proposed. To improve the user guidance it is envisaged that the nebulizer should have a signal device for generating at least one acoustic and/or vibratory signal, particularly during a nebulizing process.

For meteredly dispensing a liquid over a period of several months from a container which can be stored over a long period of time, the need is for a container which is practically diffusion-tight and in which the liquid does not come into contact with the ambient atmosphere. The cartridge according to the invention is a three-shell container comprising a collapsible bag which contains the liquid, a container which is stable in respect of shape and a stiff metal casing. The cartridge can be releasably connected to a dispensing device. The cartridge can be provided with a micro-opening with which the time for pressure equalisation between the cartridge and the ambient atmosphere can be adjusted. The cartridge is suitable for aqueous and for alcoholic liquids which contain a pharmaceutically active substance. The liquid in the cartridge is protected from external influences. The cartridge can be used in an atomiser for producing an inhalable aerosol for the treatment of illnesses.
摘要:
A locking tensioning mechanism for a miniaturised high pressure generator is disclosed, which mechanism will allow delivery of a set volume of a liquid, and the volume to be delivered by a high pressure generator can be altered subsequently by adjusting one of the stops of the spring component, which locking tensioning mechanism may be used in a high pressure generator for producing an inhalable aerosol or in a needleless injector for injecting a volume of a liquid into animal or plant tissue.

摘要:
An inhaler (1) is proposed (see FIG. 1), for the inhalation of a formulation (2) from capsules (3) that each contain one dose of the formulation. The capsules are preferably each emptied in a capsule chamber (4) by being set in motion by a stream of air flowing through the capsule chamber. The stream of air can be generated by the inhalation of a user or patient and/or can be generated actively generated by the inhaler. For simple handling, the inhaler has a means for, in particular, automatic filling, emptying and/or cleaning of the capsule chamber, if the latter is used more than once. Alternatively, the inhaler has a large number of capsule chambers that each preferably already contain a capsule and re preferably used just once.
摘要:
A nebulizer having an insertable container and a monitoring device for counting actuations of the nebulizer is proposed. The monitoring device is mounted in a detachable housing part and directly detects movements of container during a nebulizing process, an air supply current in the region of a mouthpiece, and/or the production of aerosol, in order to detect this as the actual dispensing of fluid and actuation of the nebulizer, while preferably the time of actuation of the nebulizer is additionally detected and stored. This allows better monitoring and guidance for the user.
摘要:
The present invention relates to a propellant-gas-free apparatus for the dispensing of liquids, a container cartridge suitable for this for storing the liquid and the ensemble comprising both. The invention comprises a device for the exertion of pressure and for accommodating a container cartridge and a container cartridge in which the dispensing facility is integrated.
