This creation is a kind of Needleless dosing injection device,It is planted for needleless injector and injection medicament,Owner will by shell,Cock body and pedestal composition,Wherein in the accommodating space of cock body system installing what shell,And fill in the one projection what dosing mouth of System forming protrusion and one under the protrusion to the side wall for extending and being bonded with the outer casing inner wall,It is then cut on what side wall and is mutually perpendicular to staggered tear place by multiple and is constituted a tearing port,And multiple washers with array arrangement are then cut in each tear place,Needleless injector can be allowed when carrying out injection medicament using each washer,Effectively slow down the intensity and speed of medicament injection,Allow medical staff that can more control the intensity of medicament injection simultaneously,Patient, which will not experience, has uncomfortable Medical Quality because of too strong injection speed.本創作係一種無針加藥注射裝置，其供無針頭注射器插置並注射藥劑，係主要由外殼、塞體及基座組成，其中塞體係裝設於外殼的容置空間內，且塞體係形成一突伸於該加藥口之凸部及一由該凸部下向延伸且與該外殼內壁貼合之側壁，於側壁上則切割出由多個相互垂直交錯的撕裂處構成一撕裂口，並且在各撕裂處則被切割出多個以陣列排列之檔片，利用各檔片能夠讓無針頭注射器在進行注射藥劑時，有效減緩藥劑注射的強度以及速度，同時讓醫護人員更能夠控制藥劑注射的強度，讓患者不會感受到因過強的注射速度而有不舒服的醫療品質。
