A wide variety of injection devices are known for cosmetic and medical applications, but a truly needle-free dermal layer drug delivery system is rare. Most commonly used liquid injectors have a gun-type body with a chamber or housing for loading. The drug is connected to a high-pressure gas, and the syringe is pressed against the patient's skin by using the high-pressure principle. When the trigger is pushed, the liquid medicine is sprayed from the muzzle in a column shape and injected into the skin to achieve a delivery effect, which may cause skin wounds and pain. If the drug needs to be replaced, it must be fully sterilized and disinfected. Another type is to spray the drug directly under pressure. This method of delivery still cannot meet the requirements of the speed and accurate quantification of the dermal layer.

In the early days, the applicant had developed a special drug delivery device for the needle-free syringe because of its convenience and practicability. The drug delivery structure used in the technology was discovered after implementation.
