Disclosed herein is a medical micro-mesh nebulizer capable of effectively controlling the output of ultra-fine particles atomization, mainly characterized by disposing a filter in front of the atomization module of a drug container. When the atomization module sprays the liquid medicine to form atomization gas, the sprayed atomization gas will hit the filter again to generate finer atomization gas particles (approximately 5&mgrm or less), thus enabling the patient to absorb the medicine more easily. In addition, the nebulizer allows a circulation reflow system to be disposed in the drug container to thereby automatically suck back liquid medicine, which is collected and formed after the atomization gas particles have fallen, to the drug container for spraying output, so that patients can receive adequate treatment dose, thus significantly lessening medicine waste, reducing pharmaceutical pollution brought to the environment by the excess liquid medicine discarded into the outside world.一種有效控制超微細霧化顆粒輸出的醫療微網片霧化器,主要特徵是在盛藥容器之噴霧模組的前方設置一篩選器,當噴霧模組將藥液噴出形成霧化氣體時,使該噴出的霧化氣體再次撞擊該篩選器而產生更微細的霧化氣體顆粒(約5μm以下),讓病患更容易吸收藥劑;此外,本霧化器還可以在盛藥容器設置藥液循環回流系統,藉以可自動地將霧化氣體顆粒落下後集中形成的藥液吸回至盛藥容器內再噴霧輸出,使病患接受足夠藥量治療,大幅減低藥劑浪費,減少多餘藥液丟棄於外界時對環境所造成的藥害汙染。1‧‧‧盛藥容器10‧‧‧盛藥空間101‧‧‧底面11‧‧‧注藥口12‧‧‧藥液出口13‧‧‧藥液回流系統131‧‧‧收集容器132‧‧‧氣霧導出管133‧‧‧最低位置134‧‧‧第一開口135‧‧‧第二開口136‧‧‧導管2‧‧‧噴霧模組21‧‧‧微網片22‧‧‧超音波振盪器3‧‧‧篩選器31‧‧‧表面32‧‧‧凹孔33‧‧‧凸粒34‧‧‧腳架4‧‧‧電力源L‧‧‧藥液R‧‧‧大顆粒氣霧分子F‧‧‧微細顆粒氣霧分子
