Embodiment Construction

[0024] In the drawings, the same reference numerals are used to designate equivalent or similar components even if repeated description is omitted. Specifically, equivalent or corresponding advantages and characteristics can also be obtained or realized.

[0025] figure 1 and figure 2 shows schematically in a non-stretched state according to the present invention ( figure 1 ) and stretched state ( figure 2 ) shows the inhaler 1, the inhaler 1 is used to spray the inhalation preparation 2 into an aerosol 14, specifically a high-efficiency pharmaceutical composition and the like.

[0026] The term "aerosol" here is not limited to inhalation preparations in liquid form, but may also include powder preparations.

[0027] The inhaler 1 is specifically configured as a portable inhaler and preferably operates without a gas propellant. Preferably, the inhaler 1 is portable, works only mechanically and / or is hand-held. However, the invention can also be applied to inhalers 1 us...

Abstract

A nozzle (12), an inhaler (Fig. 1) with a nozzle (12) and a method of producing the nozzle are presented. The nozzle comprises two holes (21) formed in a plate (22). The plate (21) is then deformed so that the axes of the holes intersect so that the fluid jets generated through the holes collide with each other.

Description

technical field [0001] The invention relates to a nozzle according to the preamble of claim 1 , an inhaler according to the preamble of claim 11 and a method of manufacturing the nozzle. [0002] In particular, the invention relates to the delivery of inhalation formulations through a nozzle or inhaler, preferably through a gas-free metered dose inhaler. Background technique [0003] US 2003 / 0075623 A1 describes a nozzle with one or more nozzle outlets for spraying a fluid into a mist. The nozzle consists of at least two plates which can be connected by an intermediate layer. At least the base plate has a groove structure connecting the inlet to the nozzle outlet(s). In one embodiment, two or more nozzle outlets are provided, which are oriented in such a way that the jets resulting from them collide with each other. Typically, the nozzle is made of silicon and glass plates welded together to form the channel. Filters can be built in. [0004] The invention relates in pa...
