Abstract: A nebulizer for nebulizing a liquid from a container is proposed. The nebulizer comprises a liquid pump for withdrawing the liquid in doses from the container and pressurizing the respective doses for nebulization. The nebulizer comprises in addition an air pump for temporarily pressurizing the liquid in the container to help withdrawing the liquid from a collapsible bag in the container.

Abstract: A reservoir for a nebulizer, and a nebulizer with a reservoir in which, to avoid undesirable rises in pressure, a fluid chamber of the reservoir is pre-collapsed and filled with an initial amount of fluid which is less than the maximum volume of the fluid chamber. Preferably, before being filled, the fluid chamber is compressed and/or expanded by means of gas to a defined volume which is less than the maximum volume of the fluid chamber.

Abstract: The invention relates to a high-pressure chamber for preferably atomizing or injecting metered amounts of fluid, such as pharmaceutical preparations. The components of the high-pressure chamber determining the strength thereof are made of a sintered metal body having plastic regions directly attached thereto. The plastic regions allow corrosion resistance and material compatibility of the interior of the high-pressure chamber and fluids placed under pressure therein. The shape of the sintered metal body provides the entire system with the rigidity required for high-pressure operation and with directly molded connection elements prescribing the type of connection to other components. The components of the high-pressure chamber determining the strength thereof are thereby deformed or crimped to each other, so that inexpensive and quick overall assembly processes are available.

Abstract: A fluidic component is arranged in an elastomeric shaped part the contour of which is matched to the outer contour of the component and to the inner contour of a holder. The elastomeric shaped part is chamfered towards the fluidic component on its pressure side. When the holder is assembled the elastomeric shaped part is deformed by a projection provided on a mating part and is put under uniformly distributed internal tension, after which the elastomeric shaped part surrounds the fluidic component to its full height.

Abstract: A reservoir and a nebulizer having such a reservoir are proposed. The reservoir comprises a closure for a fluid chamber with a medicament formulation that is formed by two closure members welded together. The closure comprises a particle barrier for preventing the ingress into the fluid chamber of any weld particles that may potentially be formed during the welding of the two closure members. The fluid chamber is preferably broadened in the shape of a beaver tail and is sealed lengthways with an additional strip of material.

Abstract: The invention relates to a medical hand-held device, in particular an atomizer (1), for dispensing a liquid pharmaceutical preparation from a container. The pharmaceutical preparation can be based, for example, on an alcoholic solvent. The proposed atomizer has a discharge nozzle for the pharmaceutical preparation. Located upstream from the discharge nozzle (12d, 12e) there is a multiple-stage filter system, which is composed of at least three filtering components (27, 28, 12f). The filters differ from one another in terms of their filter threshold and their filter materials and/or filter effect. In particular, the use of a filter made of sintered metal is proposed in order to avoid penetration of particles into a microstructured component (12), which can also contain a very fine filter in front of the nozzle. Alternatively or in addition, it is also proposed to use an adsorption filter in the flow path between a coarse filter and the microstructured component.

Abstract: A nebulizer for a fluid which has a conveying tube for conveying fluid and a method for producing a thick-walled capillary. The conveying tube or the capillary is of multipart and/or double-walled construction, and in particular, is made up of a number of parts, such as an inner tube and an outer tube. This construction allows the device to be manufactured more easily and cheaply, in particular, when the inner diameters are very small.

Abstract: A process and a device for dosing a pharmaceutical agent, preferably a liquid, are proposed. To achieve an enhanced dosing accuracy, a first component that is produced in batches, such as a shaped seal, is combined with a second component, such as a guide pipe selected from a suitable group guide pipes, wherein the suitable group of second components is selected based on at least one decisively significant value of the respective batch first components and is distinguished by an essential value of the second component which will optimize the sealing between the first and second components.

Abstract: A nebuliser and a container in each case with an aeration device are proposed, the aeration device being designed for the direct aeration of a liquid space in the container. The container comprises a rigid, gas-tight outer case and a closure, which is opened by connecting or inserting a delivery element. A long storage life and long service life with low loss of fluid or solvent are thereby provided in the form of a simple and inexpensive construction.
