After the strap 11 is adjusted, the elastic limiting pressure plate 16 is used to squeeze the strap 11 and limit the strap 11, thereby achieving the purpose of fixing the drainage tube body 1. The drainage tube body 1 can be used to achieve daily drainage of peritoneal effusion. When the drainage tube body 1 is blocked, a certain negative pressure can be squeezed into the lumen by pressing the airbag ball 7 to prevent lumen blockage. When the tube is blocked or the abdominal cavity needs to be flushed, During washing, the flushing liquid is introduced through the flushing port 5. When the flow needs to be adjusted, the motor 36 is used to drive the adjustment disk to rotate. During the rotation, the pressure block 38 can be used to squeeze the drainage tube body 1 to adjust the flow. In addition, the electric heating rod 43 heats the water in the upper cover body 21 and detects the water temperature through the temperature sensor 42. The heated water enters the lower cover body 22 through the drain pipe 30. The spiral infusion tube 40 drains the heated water and conducts heat to the double-layer heat-conducting pipe 39. The temperature of the flushing liquid in the drainage tube body 1 is adjusted through the double-layer heat-conducting pipe 39. The heat-conducted water enters the water inlet pipe 31 through the reflux pipe 41 and flows back to the upper cover body 21 through the micro pump 33 for recycling.
