Ampoule and needleless syringe intradermal, intramuscular injection and subcutaneous

摘要

A SOLUTION: A needleless hypodermic injection device, impact and shock injection mechanism within the housing and manually operable elongated housing, a suction force generating means cooperating with the impact shock injection mechanism provided in the housing, the safety The cooperable with the interlock mechanism, a suction force generating means and the impact shock injection mechanism, at least one having a jet orifice to allow the injection surface of the skin and drugs according to the impact applied to the drug by the impact shock injection mechanism needleless syringe and a means for receiving and holding the syringe on the ampoule in a state of communication with the suction force generating means medicament containing ampule Tsu, and causes aligned with the impact shock injection mechanism. To release the ampoule drug jet flow rate sufficient to penetrate the skin tissue held pressed against the orifice by the suction force generating means, the needle-free injector based on the position and angle of the jet orifices and and is adapted to inject intramuscularly intradermal, or subcutaneous drug.
