An elastic rubber pad 29 is located inside the sleeve groove 28. The elastic rubber pad 29 ensures that the retaining buckle 2 can rotate to a certain angle and maintains a stable position after rotation, ensuring that the retaining buckle 2 can stably secure the catheter.

[0030] Working principle: When in use, stick the fixing patch to the corresponding position on the patient's body, then open the opening 22 of the fixing buckle 2, and place the catheter inside the fixing buckle 2. Then, snap the clamping rod 23 into the clamping slot 25 to complete the fixation of the catheter. The cooperation of the air holes 111 and the breathable cotton layer 12 ensures that the fixing patch has a good breathable effect. Compared with the existing technology, the bottom adhesive layer 11 of the fixing patch of this application is evenly provided with air holes 111, and a breathable cotton layer 12 is provided above the adhesive layer 11. The cooperation of the air holes 111 and the breathable cotton can effectively improve the breathability of the fixing patch, and can effectively prevent the patient from having skin pressure sores at the position where the fixing patch is pasted. At the same time, a waterproof layer 13 is provided on the top of the fixing patch, and the waterproof layer 13 can improve the waterproof effect of the fixing patch.
