Abstract

Système d’atomisation et d’éjection de liquide pour une administration transdermique Système (10) d’atomisation et d’éjection d’un liquide (L) pour une administration transdermique comprenant : un réservoir (100) ; un tube de Venturi (200) ; un cylindre (300) ; un piston (400) agencé dans le cylindre (300) ; une unité d’entraînement (500) pour déplacer le piston (400) dans une direction dans laquelle un volume de l’espace d’admission d’air (V) augmente ; et un organe élastique (600) qui est déformé en fonction du déplacement du piston (400) et stocke une énergie élastique en lui tandis que le piston (400) est déplacé dans la direction dans laquelle le volume de l’espace d’admission d’air (V) augmente, dans lequel l’unité d’entraînement (500) comprend un mécanisme de libération d’énergie élastique (M) qui libère l’énergie élastique stockée dans l’organe élastique (600), amenant ainsi le piston (400) à se précipiter dans une direction dans laquelle le volume de l’espace d’admission d’air (V) diminue. Figure pour l'abrégé : Fig. 2Atomization and liquid ejection system for transdermal administration Atomization and liquid ejection system (10) for transdermal administration comprising: a reservoir (100); a Venturi tube (200); a cylinder (300); a piston (400) arranged in the cylinder (300); a drive unit (500) for moving the piston (400) in a direction in which a volume of the air intake space (V) increases; and an elastic member (600) which is deformed according to the movement of the piston (400) and stores elastic energy therein while the piston (400) is moved in the direction in which the volume of the intake space d air (V) increases, in which the drive unit (500) includes an elastic energy release mechanism (M) which releases the elastic energy stored in the elastic member (600), thereby driving the piston (400) to rush in a direction in which the volume of the air intake space (V) decreases.
