Abstract

L'invention concerne un appareil d'inhalation de médicament formé de préférence d'une seule feuille unitaire de matière, comprenant un boîtier externe, mobile entre des états écrasé et déployé, comprenant un premier volume. Un boîtier interne à l'intérieur du boîtier externe comprend un volume interne ou second volume. Une ouverture d'inhalateur menant au premier volume est ménagée à l'intérieur d'une paroi du boîtier externe à un premier emplacement. Une ouverture d'embouchure menant au volume interne est ménagée à l'intérieur d'une paroi du boîtier externe et du boîtier interne à un deuxième emplacement. Une soupape d'inhalation unidirectionnelle reliant le premier volume et le volume interne se trouve à l'intérieur d'une paroi du boîtier interne. Une soupape d'expiration unidirectionnelle reliant le volume interne et l'extérieur du boîtier externe se trouve à l'intérieur d'une paroi du boîtier externe et du boîtier interne à un troisième emplacement. La soupape comprend de préférence un corps élastique allongé formé d'un matériau semi-déformable ayant une résistance et une rigidité fournissant une flexibilité limitée. Une première séparation est perpendiculaire à l'axe allongé du corps élastique, et s'étend à partir d'un premier bord du corps élastique sur au moins une partie d'une largeur du corps élastique. Une seconde séparation perpendiculaire à l'axe allongé du corps élastique s'étend à partir d'un second bord du corps élastique sur au moins une partie de la largeur du corps élastique.
