The normal pressure low temperature microplasma fuel injection equipment for biomedical application is disclosed. The plasma fuel injection equipment of this invention, includes with the gas center runner and the porous insulating material and the protecting tube and the insulated case which are used as the positive electrode as the electrode and the cathode which are used. In the electrode, the plasma is injected. The gas center runner fills the gas from outside. The porous insulating material, with the electrode and the gas center runner, makes with the electrode and the gas center runner sever relations, possesses the plural passing holes which make the gas which was filled from the gas center runner the electrode pass. The protecting tube, making the gas center runner sever relations from outside, in order to protect, surrounds the gas center runner. The insulated case, inside the electrode, the porous insulating material, and the gas center runner, surrounds the part where the porous insulating material it is connected, with the electrode and the gas center runner, cuts off the fact that the discharge which happens in order to generate the plasma spreads outside. The plasma fuel injection equipment of this invention by the normal pressure is low temperature even in low voltage, it makes the plasma form whose current density is high and it is possible to inject.バイオメディカル応用のための常圧低温マイクロプラズマ噴射装置が開示される。本発明のプラズマ噴射装置は、正極として使われる電極と、負極として使われるガス注入管と、多孔性絶縁材と、保護管と、絶縁ケースとを含む。電極では、プラズマが噴射される。ガス注入管は、外部からガスを注入する。多孔性絶縁材は、電極とガス注入管との間で、電極とガス注入管とを絶縁させ、ガス注入管から注入されたガスを電極に通過させる複数の通過孔を有する。保護管は、ガス注入管を外部から絶縁させて保護するために、ガス注入管を取り囲む。絶縁ケースは、電極、多孔性絶縁材、及びガス注入管のうち、多孔性絶縁材と連結される部分を取り囲み、電極とガス注入管との間で、プラズマを発生させるために起こる放電が外部に拡散されることを遮断する。本発明のプラズマ噴射装置は、常圧で低い電圧にも低温であり、電流密度が高いプラズマを生成させ噴射することができる。
