[0048] In this embodiment, the side pipe 6 is movably arranged on the side of the drainage tube body 1. When the first end 5 of the side pipe exposes the drainage channel 14, it is convenient for the side pipe 6 to drain the effusion in front of and below the patient's lungs, and the drainage tube body 1 simultaneously drains the effusion behind the patient's lungs. The drainage is comprehensive and thorough, and the drainage effect is good. When the first end 5 of the side pipe enters the drainage channel 14, it is convenient for the drainage tube body 1 and the side pipe 6 to be taken out simultaneously, and the patient's wound is small, which is beneficial to the patient's recovery.

[0049] Specifically, as Figure 1 、 Figure 2As shown, the drainage tube body 1 includes a first end 2 and a second end 3 of the drainage tube. The first end 2 of the drainage tube is placed inside the patient's body, and the second end 3 of the drainage tube is exposed outside the patient's body. The side channel 6 includes a first end 5 and a second end 7 of the side channel. The first end 5 of the side channel is placed inside the patient's body, and the second end 7 of the side channel is placed in the drainage channel 14 and is exposed outside the patient's body together with the second end 3 of the drainage tube.

The support sleeve 8 has an arc transition. The through hole 16 at the center of the support ring 9 and the angle of the support sleeve 8 are both consistent with the drainage angle 4. When the side channel 6 is placed at an angle according to the drainage angle 4, the side channel 6 is prevented from being bent, which affects the drainage effect.

[0054] In this embodiment, by providing the anti-bending device 10 at the side through hole 11, the side channel 6 is prevented from being bent during the drainage process, which affects the drainage effect. At the same time, when the second end 7 of the side channel is pulled, it is beneficial for the first end 5 of the side channel to enter the drainage channel 14, which is convenient for integrated tube extraction, with convenient operation, saving time and effort.

[0055] When the first end 5 of the side pipe enters the drainage channel 14, as Figure 2 shown, it is convenient to take out the drainage tube body 1 and the side pipe 6 at the same time. In this embodiment, through the cooperation of the pulling device 13 and the pulling through hole 12, the first end 5 of the side pipe enters the drainage channel 14. The pulling device 13 and the pulling through hole 12 can have various structures as long as the above functions are achieved. Specifically, as Figure 4 shown, a pulling through hole 12 is provided on the side wall of the second end 3 of the drainage tube, and a pulling device 13 is provided in the pulling through hole 12. The pulling device 13 is connected to the second end 7 of the side pipe, and the pulling device 13 pulls the first end 5 of the side pipe into the drainage channel 14. A sealing ring 25 is provided at the pulling through hole 12, and internal threads are provided on the inner cylindrical surface of the sealing ring 25. Specifically, as Figure 5 shown, the sealing ring 25 is a columnar disc. An annular groove 26 is provided in the middle of the side surface of the sealing ring 25.

The annular groove 26 is sleeved on the pulling through hole 12. One end surface of the sealing ring 25 is placed outside the drainage tube body 1, and the other end surface of the sealing ring 25 is placed inside the drainage tube body 1. The sealing through hole 27 and the pulling through hole 12 are coaxial.

[0056] As Figure 4 shown, the pulling device 13 includes a pulling cover. The pulling cover is a stepped cylinder. The pulling cover includes a baffle 23 and a sealing plate 22. The diameter of the baffle 23 is larger than the diameter of the pulling through hole 12. A pulling ring 24 is provided at one end of the baffle 23. The baffle 23 and the pulling ring 24 are placed outside the drainage tube body 1. The other end of the baffle 23 is connected to one end of the sealing plate 22.

After the first end 5 of the side pipe is pulled into the drainage channel 14 through the pulling device 13, the connecting piece 28 is bent to make the end of the second end 7 of the side pipe be hermetically connected to the sealing plug 29, preventing external gas from entering the patient's chest cavity and facilitating the integrated extraction of the side pipe 6 and the drainage tube body 1.

[0058] Due to the airtightness requirement of the chest cavity, when the second end 7 of the side pipe is pulled out of the drainage tube body 1, it is necessary to ensure that external air cannot enter the patient's body through the drainage tube body 1. In this embodiment, the airtightness between the pulling device 13 and the pulling through hole 12 is ensured by the sealing ring 25. The airtightness between the second end 7 of the side pipe and the outside is ensured by the sealing plug 29.
