The present invention is that the flow control of exhaust air on passive ventilation with all possible and is to be automatically enabled to control the oxygen concentration of the intake air. To this end, the present invention is by As the oxygen gas supplied from the oxygen cylinder is filled bladder, the bladder is compressed, the oxygen in the air pocket in the ventilation device consisting of a manual, including the oxygen supply line is supplied to the patients airway, one side of the oxygen supply pipe is provided with a mouth configured to allow the connector to be in close contact with the patients airway, the other side is doedoe branching pipe, the first branch leading to the mechanism equipped with a discharge pipe the exhaust valve, the connecting pipe leading to the bladder 2Q port and branch, the branch point of the first branch and the second branch mechanism control valve mechanism, intake and exhaust conduits are installed in the intake and exhaust conduit control valve, by the pressure of the intake air when the air bag is compressed according As oxygen gas, is characterized in that the mechanism for closing the first branch and the second branch opening mechanism. Further, one end portion in the manual ventilation of the invention is the bladder, and the connector connected to the oxygen cylinder, the bottom valve is a bladder, the bladder bottom valve, the intake when the air bag is compressed oxygen gas of As by pressure, is closed, the oxygen gas in the bladder is made to be discharged into the oxygen supply line.본 발명은 수동식 인공 호흡장치에 관한 것으로, 배기 공기의 유량 조절이 가능하고 흡기 공기의 산소 농도를 조절할 수 있으면서도 자동으로 작동 가능하도록 하기 위한 것이다.이를 위하여 본 발명은, 산소용기로부터 공급되는 산소가스가 채워지는 공기주머니, 공기주머니가 압축됨에 의해, 공기주머니 내의 산소가 환자의 기도에 공급되는 산소 공급관을 포함하여 이루어진 수동식 인공호흡장치에 있어서, 산소 공급관의 일측은 환자의 기도에 밀착될 수 있도록 구성된 구강연결 관을 구비하고, 다른 일측은 관로가 분지되되, 배기 밸브가 장착된 배출관으로 이어지는 제1분기구와, 공기주머니 연결관으로 이어지는 제2분기구로 분기되며, 제1분기구와 제2분기구의 분기 지점에는 흡배기 관로조절밸브가 설치되어 있으며, 흡배기 관로조절밸브는, 흡기시, 공기주머니가 압축됨에 따른 산소가스의 압력에 의해, 제2
