NEBULIZER FOR A AEROSOLTHERAPY
First Claim
1. An ampoule nebulizer for aerosol therapy devices, comprising:
- an ampoule body defining a chamber for containing a medicament liquid to be nebulized;
a conduit extending upwards from a bottom of said chamber for an input of a flow of compressed air, said conduit terminating with a top orifice and bearing a nebulizer nozzle;
a through conduit open both towards an external environment and towards the nebulizer nozzle for an additional flow of ambient air; and
a delivery conduit extending from said chamber to deliver nebulized medicament towards a mouthpiece or an inhalation mask or a nasal adapter for use on a part of a patient, wherein a selection push-button is provided on a level with an entry of said through conduit said selection push-button being movable between a first operating position obstructing at least partially the entry of said through conduit for a first minimal atomization speed and at least a second operating position opening the entry of said through conduit for the a second higher atomization speed of the liquid medicament, said first operating position and said second operating position being defined by blocking means, said ampoule body comprising a lower element and a top cover connected to each other by screwing or bayonet, said cover having an upper hollow portion and said through conduit extending from a bottom of said upper hollow portion downwards to a proximity of said nebulizer nozzle, said selection push-button being mounted and removable in said upper hollow portion above the entry of said through conduit and said selection push-button being accessible on a level with said cover.

Abstract
This invention concerns an ampoule nebulizer per aerosol therapy at different medicament delivery speeds. It comprises a body with a through conduit (30) for the delivery of ambient air from outside. The though conduit is associated with a selection push-button (31) which moves between a first blocking or partially blocking position of the entry of said conduit for the choice of a first low feed speed and at least a second opening position of the entry of said conduit in order to choose a second higher medicament feed speed. Said positions are defined by stop means (35, 36) and between one and the other, one or more additional intermediate positions can be provided. Furthermore, the selection push-button can be associated with an additional valve (132) in order to vary the flow of ambient air from outside during functioning at low speed.
