Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a drainage tube anti-bending device. Background Technology

[0002] In medical practice, drainage tubes are an important medical device widely used for wound drainage after surgery, drainage of pleural and peritoneal effusions, and drainage of ducts such as the bile duct and urethra. These drainage tubes are usually made of soft materials such as medical-grade silicone, which have good biocompatibility and flexibility. They can effectively guide the patient's body fluids, pus, or blood to the outside, thereby preventing postoperative infection and promoting wound healing. However, during use, especially during the indwelling stage under the patient's skin, drainage tubes often face the risk of bending or compression. Because of their soft texture and the fact that they are usually placed along the patient's body curves, they are easily squeezed by external factors such as clothing and bedding, causing the drainage tube to bend. A bent drainage tube not only affects the drainage effect and causes poor drainage, but in severe cases, it may also lead to complete blockage of the drainage tube, endangering the patient's life. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a device to prevent the drainage tube from bending, thereby solving the problem that the drainage tube at the indwelling end is easily squeezed by external factors such as clothing and bedding, resulting in bending.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a drainage tube anti-bending device, comprising an anti-bending device body composed of a fixing patch, a guide seat, and an air bladder.
