Disclosed is a medical suction device system for suctioning patients secretion with low vacuum pressure. According to the present invention, the medical suctioning system discharges body fluid inside a human body to the outside and collects the body fluid and comprises: a container unit which has an empty space unit in a vacuum condition therein and has an entrance formed on an upper end portion to communicate with the space unit； and an adjustment unit which presses and deforms a portion of a first tube to adjust an amount of body fluid passing through the first tube connected to the empty space unit of the container unit. The container unit comprises: a stopper unit which is installed on an upper end portion of the container to enclose the entrance of the container unit and has a through-hole formed on one side to communicate with the entrance； and a contraction and expansion means which is joined to one side of the stopper to communicate with the through-hole of the stopper and is contracted and expanded in accordance with a vacuum degree of the container. The adjustment unit comprises: an adjustment unit main body which has a penetration path penetrated by the first tube； a compression member which is installed on a lateral side of the adjustment unit main body and moves forwards and backwards to press and deform a diameter of the first tube； and a forward and backward transfer means which adjusts the amount of body fluid passing through the first tube by moving the first tube to compress the first tube or release the first tube by backward movement as the compression member moves forwards.저진공압력으로 환자의 분비물을 흡인하기 위한 의료용 흡인기 시스템이 개시된다. 본 발명에 의한 의료용 흡인기 시스템은, 인체 내부의 체액을 인체 외부로 배출시켜 수집하기 위한 의료용 흡인기 시스템에 있어서, 용기 내부에 진공상태의 공간부를 형성하고, 그 상단에는 상기 공간부와 연통하는 출입구가 형성된 용기부； 상기 용기부의 공간부와 연결된 제1튜브를 통과하는 체액의 양을 조절되도록 상기 제1튜브의 일부분을 눌러 변형시키는 조절부；를 포함하되, 상기 용기부는, 상기 용기부의 용기 출입구를 차폐하도록 상기 용기의 상단에 장착되고 일측에 상기 출입구와 연통하는 통공이 형성된 마개부； 상기 마개의 통공과 연통하도록 상기 마개부의 일측에 연결되어, 용기부의 진공 정도에 따라 신축
