Title: NEEDLELESS SYRINGE OPERATING WITH AN IMPACT WAVE GENERATOR THROUGH A WALL
Abstract:
The technical field of the invention is that of needleless syringes used for intradermal, subcutaneous or intramuscular injections of active principle for therapeutic purposes. More particularly, the invention concerns a needleless syringe (10) comprising a propelling system, the active principle and an application guide (8), mainly characterised in that the propelling system consists of an impact wave generating device (3) and the active principle is arranged in at least a blind cavity (7) of the downstream surface (6) of a barrier (4) extended by the application guide (8). Thus, the active principle is expelled in the form of streamlined jets, driven at very high speed.
