[0002] Gastrointestinal surgical catheters are medical devices used for gastrointestinal related treatment and surgery. They can be used for drainage, perfusion or as an inspection tool to help doctors operate during gastrointestinal surgery or treatment. Common gastrointestinal surgical catheters include gastric tubes, intestinal drainage tubes, gastroscope catheters, etc. After the patient undergoes intestinal surgery, the catheter is often fixed to prevent displacement in the patient's body. Traditional gastrointestinal surgical catheters are fixed by using medical tape to bond the catheter to the human skin. This method is easy to cause loose adhesion when the patient sweats, resulting in the catheter falling off or shifting.
[0003] In order to better fix the catheter, a fixing device is often set on the guardrail on one side of the bed or on the ground to fix the catheter. However, this method is only suitable for patients who are often bedridden. Patients who are in a good recovery state and can move on the ground often need to hold the fixing device to move. During the movement, holding the fixing device may cause the catheter to be pulled, increasing the risk of the pipeline falling off or shifting.
