The invention relates to a negative pressure suction auxiliary tube, which can effectively solve problems that an existing infusion device is incomplete in suction and poor in using effect due to thefact that negative pressure is unstable and double cannulas are easily blocked by pus or excrement or necrotic tissue when the existing infusion device is combined with the double cannulas to conductabdominal cavity flushing and negative pressure suction at the same time. One end of a hose is connected with a needle seat and the other end is an open end; the outer side of the hose is connected with a drainage tube; through holes communicated inside and outside are uniformly distributed in the tube wall of the drainage tube; the through holes in the drainage tube are composed of multiple columns of through holes which are distributed in a staggered mode; the distance between every two adjacent columns is 5 mm; each column of through holes are composed of multiple round holes which are evenly distributed in the drai
