The present invention provides a drainage connecting apparatus which can simultaneously perform a drainage function and an electrocauterization function as needed. According to the present invention, the drainage connecting apparatus comprises: a first drainage tube connected to a first device including an electrocautery to heat-treat a portion of a human body undergoing surgery and a first suction unit to suck a body fluid produced during surgery and discharge the body fluid； a second drainage tube connected to a second device including a second suction unit to suck the body fluid of the human body and to discharge the body fluid； a drainage connection vessel to temporarily store the body fluid discharged from the first and second suction unit； and a third drainage tube connected to the drainage connection vessel to discharge the body fluid temporarily stored in the drainage connection vessel to the outside. One end of the first drainage tube is connected to the first suction unit, and the other end of the first drainage tube is connected to one side of the drainage connection vessel. One end of the second drainage tube is connected to the second suction unit, and the other end of the second drainage tube is connected to the other side of the drainage connection vessel. The drainage connection vessel includes a communication control unit of a plate shape to control whether to communicate with the drainage connection vessel for any one among the first and second drainage tubes while moving along an area separated from a boundary of the outer circumferential surface of an upper portion of the drainage connection vessel by a prescribed distance.COPYRIGHT KIPO 2018본 발명은 배액 연결 장치를 개시한다. 본 발명에 따른 배액 연결 장치는 상기 인체의 수술 부분을 열 처리하는 전기 소작기 및 수술에 따라 발생하는 체액을 흡입하는 제1 석션기를 포함하는 제1 디바이스에 연결되어 상기 체액을 배출시키는 제1 배액관； 상기 인체의 상기 체액을 흡입하는 제2 석션기를 포함하는 제2 디바이스에 연결되어 상기 체액을 배출시키는 제2 배액관； 상기 제1 석션기 및 상기 제2 석션기로부터 배출되는 상기 체액을 임시 저장하는 배액 연결 용기； 및 상기 배액 연결 용기에 연결되어 상기 배액 연결 용기에 임시 저장된 상기 체액을 외
