Embodiment Construction

[0025] of the sprayer figure 1 The embodiment shown in firstly has an outer housing 10 . The compressed air supply line 1 leads from above into the interior of the housing 10 . The compressed air supply line 1 terminates in the interior of the housing in a Venturi nozzle 3 , which is followed by an atomizing nozzle 4 . An impingement plate 5 is arranged opposite to the outlet of the atomizing nozzle 4 . Out of the impingement plate 5 , the nebulized medicine is output through the output pipeline 2 as an aerosol. In the end of the housing 10 opposite the compressed air supply line 1 there is a liquid collection area 7 . The liquid collecting area 7 is connected to a line 9 . In this exemplary embodiment, the line 9 is formed by the gap between the inner housing part 8 and the outer housing part 10 . The line 9 between the two housing parts runs from the liquid collecting area 7 laterally on the inner wall of the housing 10 upwards into the upper end region of the housing a...

Abstract

The invention relates to a nebulizer for nebulizing liquid active ingredient in form of aerosol, which has a housing with a lower liquid collection region for the liquid active substance; a compressed air supply line, on which a venturi nozzle and an atomizing nozzle are connected in the housing area; a pipeline connecting with the liquid collection region and being introduced to the part between the venturi nozzle and the atomizing nozzle; an impact plate opposite to the outlet of the atomizing nozzle; and a discharge line being introduced from the housing to conveniently discharging the aerosol in a floating manner. The nebulizer is arranged above the T-shaped member in a breathing hose for laid down patients. The compressed air supply line introduces in an end area of the housing, where the end area of the housing is provided opposite to the liquid collection region. The venturi nozzle and the atomizing nozzle are directed in a direction on the liquid collection region. the discharge line is passed through the lower liquid collection region.

Description

technical field [0001] The invention relates to a nebulizer for atomizing liquid active ingredients, which has: a housing with a lower liquid collection area for the liquid active ingredient; a compressed air feed line, a Venturi nozzle and an atomizing nozzle in the The interior of the housing is connected to it; the pipeline connected to the liquid collection area, which leads into the transition area between the Venturi nozzle and the atomizing nozzle; the impingement plate arranged opposite the outlet of the atomizing nozzle ( Prallplatte); and an output pipeline, which leads out from the housing in order to output the atomized liquid active ingredient in the form of aerosol. Background technique [0002] Such a nebulizer is known, for example, from DE 601 20 181 T2. In known nebulizers, a compressed air supply line runs from below into the housing of the nebulizer, which ends in a Venturi nozzle, to which the atomizing nozzle is coupled. An impingement plate is arrang...
