Detailed Description

As shown in figures 1-4, the anti-clogging drainage tube of the utility model comprises a drainage tube body 1, the front part of the drainage tube body 1 is provided with a plurality of drainage cracks 2, the drainage cracks 2 are arranged along the axial direction of the drainage tube body 1, an inner sleeve 3 is arranged in the front part of the drainage tube body 1, the inner sleeve 3 is supported with the front inner wall of the drainage tube body 1 through a plurality of support rods 4, the front end and the rear end of the inner sleeve 3 are both connected with the inner wall of the drainage tube body 1, a drainage cavity 5 is formed between the front tube wall of the drainage tube body 1 and the inner sleeve 3, the periphery of the tube wall of the inner sleeve 3 is provided with a plurality of drainage holes 6, the rear end part of the drainage tube body 1 is provided with a gas injection joint 7 and a flushing joint 8, the inner wall of the drainage tube body 1 is provided with a gas injection channel and a flushing channel 9, the gas injection joint 7 is, the irrigation channel 9 communicates with the drainage cavity 5.

The diameter of the drainage holes 6 arranged on the inner sleeve 3 is larger than the width of the drainage crack 2, so that drainage of drainage liquid is smoother, and the blockage of the drainage tube body 1 is further prevented.

The periphery of the tube wall of the drainage tube body 1 is provided with a depth scale mark 10.

The periphery of the front pipe wall of the drainage pipe body 1 is provided with a thread supporting edge 11.

When the utility model is used, medical staff inserts the anti-clogging drainage tube into the focus of a patient to perform drainage operation, and can judge the insertion depth of the drainage tube body 1 by observing the depth scale mark 10 on the outer wall of the drainage tube body 1; the drainage liquid enters the drainage cavity 5 through the drainage crack 2, then enters the inner sleeve 3 through the drainage hole 6, and finally is drained out of the patient body through the drainage tube body 1; because the drainage tube body 1 needs to be inserted into a patient for a long time, drainage liquid in the patient continuously seeps outwards, when negative pressure drainage is carried out, air needs to be continuously injected into the air injection joint 7, and the situation that the inner wall of the tissue in the patient is attached to the outer wall of the drainage tube body 1 to block a drainage crack 2 due to overhigh negative pressure in the drainage cavity 5 is avoided; if the drainage tube body 1 is blocked, the drainage cavity 5 can be flushed by injecting flushing fluid into the flushing connector 8, and blood clots coagulated in the drainage cavity 5 can be flushed away; the thread supporting arris 11 arranged on the periphery of the front tube wall of the drainage tube body 1 can also prevent the inner wall of the tissue of the patient from being attached to the outer wall of the drainage tube body 1.

The present embodiment is not intended to limit the shape, material, structure, etc. of the present invention in any form, and all of the technical matters of the present invention belong to the protection scope of the present invention to any simple modification, equivalent change and modification made by the above embodiments.
