[0002] The main applications of negative pressure drainage devices are as follows:

[0003] 1. Wound drainage: By generating negative pressure, the accumulated fluid, blood and other exudates in the wound can be effectively sucked out of the body. This method can accelerate wound healing and reduce the risk of infection.

[0004] 2. Expectorant effect: When there are elderly people at home who cannot cough up phlegm effectively or when sputum suction is needed during clinical emergency, a negative pressure drainage device can be used to assist in sputum suction to keep the airway open.

[0005] 3. Surgical assistance: During surgery, the negative pressure drain can be used to absorb blood and other fluids in the surgical area, making the surgical field clearer and helping the surgery go smoothly. It can also be used to extract fluids from the chest and abdominal cavities.

[0006] 4. Postoperative recovery: The use of a negative pressure drain after surgery can prevent the formation of subcutaneous fluid accumulation and hematoma and promote wound healing. Especially in minor surgeries, it can reduce tissue damage and prevent complications caused by large amounts of fluid accumulation.

[0007] 5. Gastrointestinal decompression: During gastrointestinal decompression surgery, the gastric tube is connected to a negative pressure drain, and the negative pressure principle is used to draw gastric or intestinal fluid out of the patient's body, thereby reducing gastrointestinal pressure, improving blood circulation, and promoting wound healing and functional recovery.

[0008] The negative pressure drainage device is provided with an expansion structure inside to expand the flattened negative pressure drainage device. During the expansion process, a negative pressure environment is formed inside the device, and the liquid in the drainage tube is introduced into the negative pressure drainage device.

At present, the existing types of negative pressure drainage products include simple low negative pressure drainage products and pre-set high negative pressure drainage products, which have the following disadvantages:

[0009] (1) The former is limited to the product material itself, which has little elasticity and generates very low negative pressure, and cannot provide higher drainage power;

[0010] (2) The latter has too high negative pressure, which poses a drainage safety risk, and the negative pressure cannot be compensated. The sealing operation requirements are high, and once a leak occurs, the product will be directly scrapped. Summary of the invention

[0013] Furthermore, the liquid inlet pipe is divided into an inner bag section, a transition section and a joint section in the direction away from the main bag. The inner bag section is fixedly connected to the upper part of the main bag, the stopcock and the anti-backflow valve are arranged in the transition section of the liquid inlet pipe, and the end of the joint section is a threaded structure.

[0014] In a possible implementation, a coagulation-promoting material is pre-installed in the main bag to promote the conversion of the drainage fluid into a solid state for easy disposal of medical waste.
