Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a drainage tube anti-falling structure. Background Art

[0002] Drainage tubes are used for clinical surgical drainage. They are a kind of medical device that guides pus, blood, and liquid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. The drainage tube is a hollow tube as a whole. When in use, the insertion end of the drainage tube is inserted into the patient's abdominal cavity or chest cavity. The tube wall near the insertion end has multiple drainage holes distributed along the tube axis. The drainage material enters the inner cavity of the drainage tube from the drainage holes and is discharged from the patient's body through the drainage end.

[0003] After the existing drainage tube is inserted into the human body, it is often fixed externally with medical tape to play a certain role in preventing pulling and slipping. However, this fixing method will form a colloidal layer on the skin surface after the tape sticks for a long time, which is difficult to clean. In addition, during the long drainage process, the tape will be affected by human sweating and human activities, causing its viscosity to decrease. Therefore, the fixing effect is poor and the drainage tube cannot be effectively limited. When pulled, the drainage tube is easily caused to fall off, affecting its use, or even requiring a second catheterization, causing harm to the patient.

[0004] In summary, there is an urgent need to design a drainage tube anti-dropout structure that overcomes the above-mentioned problems. Utility Model Content
