Dialysis drainage tube

The utility model discloses a dialysis drainage tube, which includes a dialysis feed tube and a drainage tube. The outlet of the dialysis feed tube and the drainage inlet of the drainage tube are connected together; the outer wall close to an inlet part of the dialysis feed tube is connected with the outer wall close to the outlet part of the drainage tube; the outlet of the dialysis feed tube and the drainage inlet of the drainage tube are shaped like a duck bill; a plurality of side holes are formed on the side wall of the dialysis feed tube; a plurality of side holes are formed on the side wall of the drainage tube, and have a feathery drainage structure extending to the drainage inlet direction on the side where the side holes face to the drainage outlet; and a ridge structure extends from the inner wall of the drainage tube. Therefore, the feathery drainage structure greatly enhances the earth drainage function of the drainage tube, and at the same time, the ridge structure on the inner wall of the drain
