Embodiment Construction

[0031] In the drawings, the same reference numerals are used for the same or similar components that lead to corresponding or comparable characteristics and advantages, even if the related description is not repeated.

[0032] FIGS. 1 and 2 show a known atomizer 1 that atomizes a fluid 2, specifically a high-efficiency pharmaceutical ingredient, etc., schematically showing a non-compressed state (FIG. 1) and a compressed state (FIG. 2). The nebulizer 1 is constructed, in particular, a portable inhaler and preferably operates without gas propellant.

[0033] When the fluid 2, preferably a liquid, more specifically a medicinal ingredient is atomized, it forms an aerosol that can be breathed or inhaled by a user (not shown). It is usually inhaled at least once a day, more specifically several times a day, and the interval is preferably set according to the pain suffered by the patient.

[0034] The known atomizer 1 has a container 3 containing a fluid 2 which can be inserted and pref...

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.

Description

Technical field [0001] The invention relates to an atomizer according to the preamble of the claims and a method of producing thick-walled capillaries. Background technique [0002] Nebulizers available under the trade name "Respimat" in the form of inhalers are known. The basic principle is shown in WO 91 / 14468A1, and the specific structure is described in WO 97 / 12687A1 (Figures 6a, 6b) and attached The graph is shown in Figures 1 and 2. The atomizer has a conveying device with a conveying tube for conveying and atomizing fluid. The transfer tube is specifically configured as a thick-walled large capillary tube, as shown in Figure 3b of WO 97 / 12687A1. Therefore, the manufacture of the transfer tube is very difficult and complicated. [0003] Capillaries with small inner diameters and thin walls are usually available. However, thick-walled capillaries with thick walls and small manufacturing tolerances are very difficult to manufacture and often have undesirable rough inner walls...
