Abstract: A nebulizer is proposed as depicted in exemplary FIG. 7 which comprises a replaceable container, a counting device and a lock for locking the nebulizer against further use. The container is provided with an electronic storage which is electrically connected to the counting device. The nebulizer comprises an electric drive for actuating the lock. This allows secure operation and/or simple handling of the nebulizer.

Abstract: The invention relates to a method for coating a surface (44), in particular a microstructured surface, of a component (55) comprising different materials, in particular glass and silicon, wherein the surface (44) is first activated and then coated, wherein an oxidising solution, a basic solution or an acid-oxidising solution is used to activate the surface (44).

Abstract: A nebulizer is proposed which comprises a replaceable container containing fluid, a housing part detachable from the nebulizer for replacing the container, and an operation counter inseparable from the housing part as depicted in exemplary FIG. 10. The operation counter comprises a lead screw and an associated rider both supported by the housing part.

Abstract: A medical hand-held device, in particular an atomizer, for dispensing a liquid pharmaceutical preparation from a container with a discharge nozzle for the pharmaceutical preparation and located upstream from the discharge nozzle there is a multiple-stage filter system.

Abstract: A nebulizer for a fluid, particularly for medical aerosol treatment is proposed. To allow easier operation and confer improved operational reliability a sealed container holding the fluid is already arranged in the nebulizer when it is supplied and the nebulizer is constructed so that the container is opened inside the nebulizer before or during the first use of the nebulizer. For this purpose, a transportation lock is provided for the sealed container which, in the delivery state, is in engagement with the sealed container in a manner preventing the sealed container from moving axially in the nebulizer.

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 medical hand-held device, in particular an atomizer (1), for dispensing a liquid pharmaceutical preparation from a container with a discharge nozzle for the pharmaceutical preparation and located upstream from the discharge nozzle there is a multiple-stage filter system.

Abstract: A nebulizer which has an insertable container and a counter device for counting operations of the nebulizer, and is opened for replacing the container. A securing device having locking portions which are forced apart is provided to prevent reconnection of an already used container. The nebulizer has an indicator for showing the current container number and/or symbols indicating the need container replacement. The indicator is driven by the force of an internal spring. The indicator member also controls a lock of the container for locking the container against further actuation. The lock is reset after container replacement.

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 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.
