Description

TECHNICAL FIELD The present invention relates to a handpiece for cosmetic and medical devices, and more particularly to a handpiece for cosmetic and medical devices for spraying liquid cosmetics or liquid medicines onto the skin of the human body.

WO2009/047173A2 discloses an atomizer for atomizing fluids. As shown in FIG. 1, a prior art nebulizer comprises an insertable cartridge for storing fluid, a housing for containing the cartridge, and a pressure generator having a drive spring for pressurizing the dose of fluid to be nebulized. including. The nebulizer further includes a carrying tube insertable within the cartridge to withdraw a dose of fluid from the cartridge when the drive spring is pulled.

WO2009/103510A1 discloses a sprayer comprising a pre-inserted cartridge storing the fluid to be sprayed. The cartridge includes a flexible carrying tube for carrying fluid out of the cartridge.

WO2010/094305A1 discloses a liquid dispensing nebulizer comprising a cartridge having a reservoir containing a liquid and a pressurized gas that forces the liquid out of the reservoir through a valve to dispense the liquid. .

WO2012/130757A1 relates to a portable device, in particular a nebulizer, for dispensing a liquid pharmaceutical formulation from a container having a container cap. Pharmaceutical formulations may, for example, be based on alcoholic solvents. An atomizer with an inserted container includes a sealing system consisting of two seals at the junction between the device and the container that prevents liquid loss, diffusion leakage, and gas exchange at this site.

Depending on the spatial orientation of such a nebulizer/cartridge, fluid collection can be affected. In particular, a residual amount of fluid may remain in the cartridge after final delivery of a dose, because a sufficient amount of fluid may not be recovered from the cartridge and/or gas or air may be inhaled and/or the entire volume may not be used. There are remaining problems.

To solve such problems, WO98/46522A1 discloses a cartridge having a storage medium and fluid such as a sponge. A rigid or flexible tube for collecting fluid is either rigidly attached to the wall of the cartridge or ends in a storage medium that can swing freely with the collection tube. The storage medium maintains a constant amount of fluid even when the end of the tube is above the fluid level in the cartridge. In such a manner, fluid can be retrieved from the cartridge essentially independently of its spatial orientation. Nonetheless, there is the problem that a certain residual amount of fluid remains in the cartridge or storage medium that cannot be recovered.

Therefore, there is a need for a technique that can solve the problems of the prior art described above.
