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 ).
