[0002] A drain is a medical device that is used during surgery or treatment to remove fluid, gas, or other material that has built up in the body to help the patient recover. Drains are usually made of soft medical materials, such as silicone or polyurethane, to adapt to the bending and movement of the body. They can be inserted into the body through a small incision in the skin or into a natural cavity, such as the nose, urethra, etc.

[0003] At present, the protection of drainage tube incision mainly focuses on ensuring the safety, effectiveness and cleanliness of the drainage tube, avoiding potential risks such as falling off, blockage, infection, etc., mainly using adhesive tape or fixing stickers to properly fix the drainage tube to prevent it from falling off or shifting. During specific operations, it is necessary to avoid folding, excessive bending or pressure on the drainage tube to ensure that the drainage fluid can flow out smoothly.
