Description

Technical Field

[0001] The present application relates to a stably assembled drainage tube. Background Art

[0002] The drainage tube, that is, the built-in tear duct, is placed in the tear duct to drain after the tear duct is diseased or damaged. In order to ensure the stability of the drainage tube, a circular protrusion is generally provided on the top of the drainage tube, and it is hung in the assembly to ensure the overall stability. However, it is precisely because of the setting of the circular protrusion that the following problems are brought about: first, the assembly process is difficult and requires strong pulling; second, due to the difficulty of assembly, the drainage tube causes damage to the tissue; third, it is easy to cause discomfort to the patient. In fact, it is because the structural design of the circular protrusion of the drainage tube is somewhat unreasonable. Utility Model Content

[0003] In order to solve the above problems, the present application proposes a drainage tube with stable assembly, including a tube body, a frustum section arranged on the upper part of the tube body, and a hanging section arranged on the upper part of the frustum section; the cross-sectional area of ​​the hanging section gradually increases from bottom to top, an oblique section is arranged on the top of the hanging section, and an arc-shaped reinforcement block is arranged on the top of the oblique section. The present application adopts a tube body, a frustum section and a hanging section arranged in sections to form a drainage tube, and the gradually arranged hanging section is used as a hanging ear for positioning. During assembly, it will not cause jamming, and it is easier to squeeze into the installation position, and it will not cause discomfort to the patient after installation.

[0004] Preferably, the outer edge of the oblique cut surface is provided with a chamfer edge.

[0005] Preferably, an annular protrusion is provided at the lower part of the chamfer edge, and the arc-shaped reinforcement block is provided on the arc-shaped reinforcement block. The annular protrusion used in the present application can strengthen the top structure, ensuring that after installation, the annular protrusion strengthens the hanging section and does not deform.

[0006] Preferably, the outer edge of the arc-shaped reinforcement block is arranged flush with the outermost end of the oblique section.

[0007] Preferably, the tube body comprises an upper outlet section connected to a middle accumulation section, and a lower contraction section is arranged at the lower part of the middle accumulation section.

[0008] Preferably, the inner diameter of the upper lead-out section is gradually increased from top to bottom to form a middle accumulation section at the bottom of the upper lead-out section, and then the inner diameter of the lower contraction section is gradually reduced from top to bottom to form a lower contraction section.

[0009] Preferably, a plurality of vertical outlet grooves are provided inside the lower contraction section.

[0010] Preferably, the inner walls of the upper outlet section and the lower contraction section are in a frustum shape; the inner wall of the middle accumulation section is in a cylindrical shape. The upper outlet section of the tube body of the present application can guide the tears as quickly as possible, then slow down after reaching the middle accumulation section, and finally slowly flow out of the tube body through the lower contraction section, thereby ensuring faster and continuous completion of tear drainage, and avoiding tear overflow when there are more tears as much as possible.

[0011] This application can bring the following beneficial effects:

[0012] 1. The present application adopts a segmented tube body, a frustum segment and a hanging segment to form a drainage tube, and the gradually arranged hanging segment is used as a hanging ear for positioning. During assembly, it will not cause jamming and is easier to squeeze into the installation position. It will not cause discomfort to the patient after installation.

[0013] 2. The present application adopts an annular protrusion to strengthen the top structure, ensuring that after installation, the annular protrusion reinforces the hanging section and does not deform.

[0014] 3. The upper outlet section of the tube body of the present application can outlet the tears as quickly as possible, then slow down after reaching the middle accumulation section, and finally slowly flow out of the tube body through the lower contraction section, thereby ensuring faster and continuous tear outlet, and avoiding tear overflow when there are too many tears as much as possible.

The outer edge of the oblique section 4 is provided with a chamfer 6. An annular protrusion 7 is arranged at the lower part of the chamfer 6, and the arc-shaped reinforcement block 5 is arranged on the arc-shaped reinforcement block 5.
