[0023] As Figure 1 And Figure 2 As shown in a kind of peritoneal cavity drainage tube, including outer sleeve 1 and the liquid suction tube 2 of being set in outer sleeve 1, flushing cavity 3 is formed between outer sleeve 1 and liquid suction tube 2, the both ends of flushing cavity 3 are closed structure, flushing pipe 4 is connected on outer sleeve 1, flushing pipe 4 is communicated with flushing cavity 3, a plurality of flushing holes 5 are arranged in the side wall of outer sleeve 1, flushing hole 5 is communicated with flushing cavity 3, a plurality of connecting pipes 6 are arranged between outer sleeve 1 and liquid suction tube 2, the both ends of connecting pipe 6 are connected with outer sleeve 1 and liquid suction tube 2 respectively, one end of connecting pipe 6 is communicated with the outside of outer sleeve 1, the other end is communicated with the inside of liquid suction tube 2, in the utility model, when the patient is drained, the drainage tube is inserted into patient's body, flushing equipment is connected with flushing pipe 4, drainage equipment is connected with liquid suction tube 2, flushing equipment injects flushing fluid into flushing cavity 3 through flushing pipe 4, because liquid suction tube 2 is located in outer sleeve 1, therefore flushing fluid in flushing cavity 3 will not enter the inside of liquid suction tube 2, flushing fluid can be discharged from flushing hole 5 in the side wall of outer sleeve 1, flushing is carried out to patient's body, after flushing is completed, drainage equipment is started to make negative pressure in liquid suction tube 2, the effusion in patient's abdominal cavity can be sucked into liquid suction tube 2 from connecting pipe 6 and discharged from liquid suction tube 2, in the process of washing and drainage, flushing fluid is discharged from flushing cavity 3, will not enter liquid suction tube 2, and the abdominal cavity effusion enters liquid suction tube 2 from connecting pipe 6, will not enter flushing cavity 3, therefore flushing fluid and effusion are separated from each other, avoid mixing, and flushing can also be carried out simultaneously when draining, so that the effusion into flushing cavity 3 can also be avoided.

[0024] Further, one end of the suction tube 2 is provided with a blocking plate 7, which is in a circular arc structure, and can avoid causing damage to the patient when the drainage tube is inserted into the patient's body.

[0025] Further, a through hole 8 is formed in the blocking plate 7, which is in communication with the inside of the suction tube 2, and the accumulated fluid in the abdominal cavity can also enter the suction tube 2 from the through hole 8 for drainage.

[0026] Further, a plurality of the connecting tubes 6 and the flushing holes 5 are spirally distributed on the outer sleeve tube 1, the connecting tubes 6 and the flushing holes 5 are arranged alternately, and the flushing holes 5 and the connecting tubes 6 are spirally distributed on the outer sleeve tube 1, which can flush and drain the abdominal cavity in a larger range, so that the abdominal cavity can be cleaned in all directions.

[0027] Further, a spiral flushing groove 9 is arranged on the outer wall of the outer sleeve tube 1, the flushing hole 5 and the connecting tube 6 are arranged in the flushing groove 9, after the drainage tube is inserted into the patient's body, the tissues in the patient's body are easy to block the flushing hole 5 and the connecting tube 6, which reduces the flushing and drainage effect, while the flushing groove 9 is arranged on the outer wall of the outer sleeve tube 1, the flushing hole 5 is located at the bottom of the flushing groove 9, and one end of the connecting tube 6 is also located at the bottom of the flushing groove 9, so that the tissues in the patient's body cannot block the flushing hole 5 and the connecting tube 6, and the flushing liquid and the abdominal cavity fluid can flow along the flushing groove 9, thereby improving the flushing and drainage effect.

[0028] Further, a catheter 10 is arranged in the suction tube 2, the catheter 10 is a bendable hollow tube, which can keep the shape unchanged without external force, a water passing hole 11 is formed in the tube wall of the catheter 10, the catheter 10 is made of metal material, and in this embodiment, it is made of stainless steel material, since the drainage tube is generally made of silicone rubber or polyurethane material, the drainage tube is relatively soft and easy to bend, and after being inserted into the patient's body, the position of the drainage tube is not easy to determine and adjust, therefore, in this embodiment, after the drainage tube is inserted into the patient's body, the catheter 10 is bent to a certain angle and shape by artificial bending, and then the catheter 10 is inserted into the suction tube 2 of the drainage tube, the drainage tube in the patient's body can be deformed by the insertion of the catheter 10, so as to move to a suitable position, and the medical staff can rotate one end of the catheter 10 located outside to adjust the drainage tube in the patient's body; at the same time, since the catheter 10 is supported by metal material, the position of the catheter 10 can be displayed under B-ultrasound scanning, so as to adjust the position of the drainage tube in the body and make the drainage tube in a suitable position.
