The present invention relates to an artificial respirator. The present invention comprises: a housing which is provided with a supply port connected to an oxygen tank and a discharge port which connects to the oral cavity or the nasal cavity of a patient a depressurizing valve, which is provided inside the housing, for reducing the pressure of oxygen in the oxygen tank that is supplied through the supply port of the housing to supply air an air supply control valve for providing a passage for the oxygen provided by the depressurizing valve and controlling air supply by opening or closing the passage a flow control valve for controlling the flow of oxygen provided by opening the air supply control valve and an air supply flow path for receiving supplied air from the flow control valve and guiding same toward the discharge port of the housing. The present invention enables smooth artificial respiration by guiding oxygen which has been depressurized by the depressurization valve to the air supply flow path.本發明涉及人工呼吸裝置,包括:外殼,具備連接到氧氣槽的供應口,具備連接到患者的口腔或鼻腔的排出口;減壓閥,內置於所述外殼,對通過所述外殼的供應口供應的所述氧氣槽的氧氣壓進行減壓而供氣;供氣控制閥,提供由所述減壓閥提供的氧氣的移動路徑,通過開放或關閉所述移動路徑而控制供氣;流量控制閥,控制根據所述供氣控制閥的開放運轉而提供的氧氣的流量;及供氣流路,從所述流量控制閥接收氧氣而將其引導到所述外殼的排出口。本發明因將減壓閥中減壓的氧氣引導到供氣流路,能夠順暢地實施人工呼吸。42‧‧‧流量調整閥部件43‧‧‧旋鈕44‧‧‧連接器48‧‧‧旋轉環50‧‧‧嵌入突起51‧‧‧突起夾座52‧‧‧切割部53、53a‧‧‧隔離突起54‧‧‧螺栓55‧‧‧結合孔56‧‧‧第一邊翼57‧‧‧第二邊翼58‧‧‧螺栓58a‧‧‧螺栓孔60‧‧‧供氣流路61‧‧‧供氣管90‧‧‧溢出單元L‧‧‧隔離距離
