System for atomizing and ejecting liquid for transdermal delivery

Abstract

The present invention relates to a system () for atomizing and ejecting a liquid (L) for a transdermal delivery. The system () comprises: a tank () for holding the liquid (L); a Venturi tube () comprising a longitudinal central axis (X) and an internal passage () extending along the axis (X), wherein the internal passage () is fluidly connected to the tank () via an orifice () defined in the Venturi tube (), wherein the internal passage () comprises a converging section (), a diverging section () and a throat section () located between the converging and diverging sections (); a cylinder () comprising a longitudinal central axis (X), an end wall () orthogonal to the axis (X), a circumferential wall () extending from the end wall () along the axis (X) and an outlet hole () formed on the end wall (), wherein the outlet hole () is fluidly connected to an inlet () of the converging section (); a piston () arranged in the cylinder () so as to be displaceable in the cylinder () along the axis (X), wherein the piston () defines an air intake space (V) in the cylinder () in cooperation therewith, wherein the air intake space (V) fluidly communicates with the inlet () of the converging section () via the outlet hole (); a driving unit () for displacing the piston () in a direction in which a volume of the air intake space (V) increases; and an elastic member () that is deformed according to the displacement of the piston () and stores an elastic energy therein while the piston () is being displaced in the direction in which the volume of the air intake space (V) increases. The driving unit () comprises an elastic energy release mechanism (M) that releases the elastic energy stored in the elastic member (), thereby causing the piston () to rush in a direction in which the volume of the air intake space (V) decreases.
