Detailed Description

To facilitate understanding of the present invention for those skilled in the art, embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, the utility model provides a drainage tube, which comprises a drainage cavity 100, an initial end 201, a drainage end 202 and a surrounding wall 200 extending from the initial end 201 to the drainage end 202 and wrapping the drainage cavity 100. The surrounding wall 200 is made of a material with a shore hardness of 40-60 HA. If the shore hardness is less than 40HA, the tube may be too soft and may kink, thereby resulting in blockage of drainage lumen 100 and ventilation lumen 300. When the drainage tube with the Shore hardness of more than 60HA is used, the drainage tube is not easy to bend, and the use is influenced.

The enclosure wall 200 is provided with at least one drainage segment adjacent the drainage end 202. The drainage section comprises a drainage section with at least 2 drainage holes 101 and a drainage connecting section without any drainage holes 101, the drainage holes 101 are communicated with the drainage cavity 100, and the axial length of the drainage connecting section is larger than the distance between any two adjacent drainage holes 101.

Preferably, the drain holes 101 are uniformly arranged in the drainage segment at an axial distance of 5mm to 20mm, the total length of the drainage segment is about 200mm to 350mm, and the total length of the drainage connecting segment is about 400mm to 650 mm.

At least one vent cavity 300 extending from the initial end 201 to the drainage end 202 and parallel to the axis of the drainage cavity 100 is disposed on the surrounding wall 200, the vent cavity 300 is isolated from the drainage cavity 100, and the cross-sectional area of the drainage cavity 100 is larger than that of the vent cavity 300. The ventilation cavities 300 are arranged on the end face of the surrounding wall 200 by taking the axis of the surrounding wall 200 as the center of a circle, the offset angle between any two adjacent ventilation cavities 300 is 360 degrees/n, and n is the number of the ventilation cavities 300. Preferably, the offset angle between any two adjacent venting lumens 300 ranges from: 60 to 180 degrees. The enclosure wall 200 is provided with at least one venting section near the drain end 202. The venting section comprises a venting arrangement section 301 with a plurality of venting holes 301 and a venting connection section not comprising any venting holes 301, the axial length of the venting connection section is larger than the distance between any two adjacent venting holes 301.

The material of leg 200 is silica gel, and the external diameter is 6mm to 10mm, and the thickness of leg 200 is 0.2 ~ 0.7mm, the cross section of flowing back chamber 100 is about 3mm to 4mm, the diameter of outage 101 is 0.5 ~ 1.5 mm.
