[0002] In the hospital clinic, the patient who got cirrhosis disease often appears liver ascites problem, and timely pumping out liver ascites outside the body is an effective treatment method, which can prevent the disease from further deterioration.

[0003] The current ascites pumping method is pumping ascites through an ascites pump or a syringe, and then the puncture needle is inserted into the abdominal cavity, and then the pump or the syringe is used for pumping. In order to avoid repeated puncture to bring pain to the patient, the puncture hole of the abdomen is retained for treatment, which is convenient for the next pumping.

[0004] In the prior art, for example, Chinese invention patent application publication number: CN 108096686 A discloses a thoracic and abdominal cavity drainage tube, which comprises a guide tube, the two ends of the guide tube are respectively a drainage input end for inserting into the thoracic and abdominal cavity and a drainage output end for remaining outside the thoracic and abdominal cavity, the drainage input end is provided with a plurality of drainage holes, the guide tube is externally sleeved with a flexible water bag sleeve which can be injected with water, the flexible water bag sleeve is connected with a water injection assembly, the flexible water bag sleeve has a wrapping part which tightly wraps the guide tube when the flexible water bag sleeve is not injected with water and expands to form an expanded inner cavity when the flexible water bag sleeve is injected with water, the drainage input end and all the drainage holes are located in the expanded inner cavity, and the wrapping part has a plurality of filter holes which communicate the expanded inner cavity with the external environment. The thoracic and abdominal cavity drainage tube has the advantages of simple structure, low cost, convenient operation and use, and complete drainage without adjustment.

[0005] In the above patent technical solution, first, the stopper part is expanded and expanded by injecting water into the flexible water bag sleeve, and the expanded stopper part abuts against the inner side of the chest wall and the abdominal wall to prevent the guide tube from being pulled out, which can ensure the reliable drainage. The disadvantage is that once the guide tube is pulled by external force, the pulling force will be transmitted to the inner side of the chest wall and the abdominal wall due to the expanded stopper part, which will cause compression injury to the chest wall and the abdominal wall in the wound area, causing great pain to the patient.

[0006] In addition, in the above patent technical solution, the annular water bag and the stopper part cooperate to clamp and fix the chest wall or the abdominal wall, which plays a role in fixing the guide tube. However, since the annular water bag and the stopper part clamp the chest wall or the abdominal wall where the wound is located, the patient does not have comfort when using, the fixing method is not convenient, the fixing effect is not good, and the patient will also feel pain, which is not conducive to precise clamping operation.

[0007] Finally, the flexible water bag sleeve between the retreat stop portion and the annular water bag in the above patent technical solution is inflated by water, which can only partially block the puncture channel of the chest wall or abdominal wall, but cannot completely block the body fluid overflow, which is a common sense problem. However, no further innovative design is made in the overflow prevention part, so that the patient cannot be properly treated when the tissue fluid or pus overflows, and the skin around the affected area is contaminated or dirty.

[0010] On the other hand, the tissue fluid in the wound can be prevented from overflowing outward. Even if the wound overflow prevention barrier fails, the annular absorption structure can well realize the absorption and barrier effect of the tissue fluid or pus overflowing from the wound, and greatly reduce the skin contamination area of the patient.

[0011] In addition, the water suction pipe can resist the strong pulling of the outside world, reduce the withdrawal amplitude to a certain extent, avoid that a large pulling force is transmitted to the inside of the wound, the inside of the chest wall and the abdominal wall of the region where the wound is located is damaged due to compression, and the problem of great pain is brought to the patient, and the arrangement and storage are convenient.

[0067] In the present embodiment, the cooperation between the air pipe, the air bag, the one-way air valve, the deflation valve and the airtight cavity in communication with one end of the air pipe enables the air bag on the outer periphery of the drainage tube to inflate and deflate freely, and when the air tube is inserted into the wound, the air bag has an inclined slope surface at the end away from the sticking limiting structure, which enables the air tube to have a guiding effect during the insertion process and does not cause pain to the patient's wound, and is more beneficial to the insertion of the drainage tube into the wound.

[0068] As shown in Figure 1 , Figures 5 to 7 The sticking limiting structure 2 further preferably comprises a support layer 21, a cold gel layer 22 connected to the side of the support layer 21 away from the tube limiting structure 6 and a release layer 23 connected to the side of the cold gel layer 22 away from the support layer 21, the cold gel layer 22 is provided with a half-cut annular notch 24 for accommodating the ring-shaped absorption structure 3;

[0107] It should be particularly noted that, with respect to step three, the opposite deflation process is as follows: the deflation valve 54 is manually adjusted so that the air bag 51 on the outer periphery of the suction tube 1 gradually moves away from the inner surface of the wound until it is not in contact with the inner surface of the wound.

[0108] Tube extraction process: after the air bag 51 on the outer periphery of the suction tube 1 is not in contact with the inner surface of the wound, the anti-lifting structure 4 and the adhesive limiting structure 2 are sequentially removed, so that the wound suction and overflow prevention device can be completely separated from the wound of the patient.
