the oxygen supply and carbon dioxide emissions are mixed in advance to prevent the anatomic dead space that is provided to patients Once supplied to the ventilation reduces the patient is reduced by reducing the pressure of the air applied to the lung of the patient, a pulmonary disease in the lung yusundo is to protect the lungs of the patient reduces the endotracheal tube to reduce the anatomical dead space The breathing circuit is disclosed having. Breathing circuit to the invention with an oxygen breathing apparatus, it is provided with an endotracheal tube top, and one expiratory breathing apparatus which is connected to the breathing tube breathing tube and air intake exposed to outside agencies, and the intake of breath breathing tube breathing tube The other end includes connection pipe, which is connected directly to the endotracheal tube. Endotracheal tube and a tube body, and the inner arc of the engine and the inlet pipe is connected is formed in the upper portion of the exhalation breathing tube and the intake tube body fixed to the other end as well as inside the tube body of the breathing tube, and formed in the interior of the tube body In addition, extending along the longitudinal direction of the tube body to obstruct partition for dividing the inside of the tube body and call engine to be provided with a intake pipe, and a. The endotracheal tube becomes swollen as a No. institutional side is divided obstruct the breathing circuit during the inspiratory breath while extending the intake duct having a closed institution and to the call, while extending the call to the agency side to the intake pipe becomes swollen during aerobic respiration prevent the carbon dioxide and oxygen are mixed to be supplied is discharged due to close the air intake pipe and able to reduce the anatomical dead space.배출되는 이산화탄소와 공급되는 산소가 혼합되어 환자에게 제공되는 것을 미연에 막아 해부학적 사강을 줄여 환자에게 공급되는 일회 환기량을 감소시켜 환자의 폐실질에 가해지는 공기의 압력을 감소하여, 폐질환으로 폐의 유순도가 감소된 환자의 폐를 보호할 수 있는 해부학적 사강을 감소하는 기관
