SYSTEM FOR ATOMIZING AND EJECTING LIQUID FOR TRANSDERMAL DELIVERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240033757 titled 'SYSTEM FOR ATOMIZING AND EJECTING LIQUID FOR TRANSDERMAL DELIVERY

Simplified Explanation

The present invention is a system for atomizing and ejecting a liquid for transdermal delivery. The system includes a tank for holding the liquid, a venturi tube with an internal passage fluidly connected to the tank, a cylinder with an outlet hole connected to the venturi tube, a piston arranged in the cylinder, a driving unit for displacing the piston, and an elastic member that stores elastic energy while the piston is being displaced.

  • The system includes a tank for holding the liquid.
  • A venturi tube is connected to the tank and has an internal passage.
  • The venturi tube includes a converging section, a diverging section, and a throat section.
  • A cylinder is connected to the venturi tube and has an outlet hole.
  • The outlet hole is connected to the converging section of the venturi tube.
  • A piston is arranged in the cylinder and can be displaced along its axis.
  • The piston defines an air intake space in cooperation with the cylinder.
  • The air intake space communicates with the converging section of the venturi tube.
  • A driving unit is provided to displace the piston and increase the volume of the air intake space.
  • An elastic member is deformed by the displacement of the piston and stores elastic energy.
  • The driving unit includes an elastic energy release mechanism that releases the stored elastic energy, causing the piston to rush in the opposite direction and decrease the volume of the air intake space.

Potential applications of this technology:

  • Transdermal drug delivery systems
  • Inhalers or nebulizers for respiratory medications
  • Cosmetic sprays or mists for skincare products

Problems solved by this technology:

  • Efficient atomization and ejection of liquid for transdermal delivery
  • Controlled and precise delivery of medications or cosmetic products
  • Reduction of waste and improved dosage accuracy

Benefits of this technology:

  • Enhanced absorption and effectiveness of transdermal medications
  • Improved convenience and ease of use for patients
  • Reduced environmental impact through efficient liquid delivery


Original Abstract Submitted

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.
