The present invention relates to a drainage prevention drainage pipe, comprising: a main pipe having one end inserted into a diseased part of a patient and the other end connected to an aspiration drainage device to form a hollow cylinder for discharging blood and body fluid generated in the affected part to the aspiration drainage device； And a pair of fixing device protrusions protruding from an outer circumferential surface of the main pipe and having coupling holes into which the fixing devices are coupled. And the pair of fixing device connection portions are symmetrically positioned on both sides of the outer peripheral surface of the main pipe. Here, the fixing unit connection part is made of a material having a higher ductility than the main pipe, and when the external force is applied from the fixing device, the shape of the fixing device connection part is easily deformed to prevent the diameter change of the main pipe. In addition, the fixing device connecting portion may have one or more protrusions on the surface thereof to prevent the detachment of the fixing device from the fixing device connecting portion by increasing the fixing force of the coupling portion when the fixing device is coupled to the fixing device connecting portion. Through this, the drain tube for escape prevention is extended from the main pipe so that the fixing device connecting portion having the fitting hole and the fixing device are combined with each other, so that the diameter of the drain tube can be changed by the fixing device and the installation position of the drain tube can be easily fixed without damaging the skin tissue have.본 고안은 이탈방지용 배액관에 관한 것으로, 일단이 환자의 환부에 삽입되고 타단이 흡인 배액 장치에 연결되어 상기 환부에서 발생된 혈액 및 체액을 상기 흡입 배액 장치로 배출하도록 중공의 원통을 형성하는 본관； 및 상기 본관의 외주면에 돌출 형성되며, 고정장치가 결합되는 결합구멍을 가지는 한 쌍의 고정장치 연결부；를 포함하며. 상기 한 쌍의 고정장치 연결부는 본관의 외주면에 양쪽으로 대칭되어 위치하는 것을 특징으로 한다.여기서, 상기 고정장치 연결부는 상기 본관과 비교하여 연성이 큰 재질로 마련되어, 상기 고정장치로부터 외력이 작용하면 상기 고정장치 연결부의 형태가 용이하게 변형됨으로써 상기 본관의 직경 변화를
