[0003] When patients use catheters for drainage, such as peritoneal drainage catheters and urinary catheters, one end of the catheter is left in the body and the other end is placed outside the body. When patients are transported or engaged in daily activities, they need to store the catheter to prevent it from falling off or even tearing the body. For example, the patent with publication number CN218652698U relates to a fixing device for preventing epidural catheters from falling off. In order to fix the catheter, a fixing belt is provided. The catheter is placed in a fixing block and tied to the waist and abdomen with the fixing belt. The above patent can effectively solve the problem of catheter fixation. However, due to different patient populations and different body shapes, the fixing belt used cannot provide stable fixation for every patient. The difference in body shape can easily cause the fixing belt to slip, which ultimately affects the fixation. Utility Model Content

[0023] The interior of the accommodating cavity 12 is evenly distributed with winding discs 13, and the winding discs 13 are staggered up and down. The winding discs 13 are used to surround the catheter. The outer cover 11 and the bottom of the shell 1 are both provided with pipe holes 14. A part of the catheter is wound on the winding discs 13. One end of the catheter is placed inside the accommodating cavity 12, and the other end of the catheter is placed inside the body.
[0024] The ends of the two groups of elastic bands 21 are respectively fixedly connected with the first magic band 22 and the second magic band 23. The elastic band 21 is wrapped around the waist, and then the first magic band 22 and the second magic band 23 are adhered to each other to complete the fixation.
[0025] The adjustment component 5 includes a fixed plate 51 fixedly connected to the upper and lower parts of the shell 1, and the fixed shaft 3 is rotatably connected between the two groups of fixed plates 51. The adjustment component 5 also includes a sliding plate 52 slidably connected to the inside of the shell 1. Two groups of sliding plates 52 are arranged up and down, and the movable shaft 4 is rotatably connected between the sliding plates 52.
[0026] A slider 521 is installed on the top of the sliding plate 52, and the sliding plate 52 is slidably connected to the inside of the shell 1 through the slider 521. A guide shaft 53 is fixedly connected to the inside of the shell 1, and a first spring 522 is mounted on the outside of the guide shaft 53. Both ends of the first spring 522 are located between the sliding plate 52 and the inner wall of the shell 1. The first spring 522 can always keep the fixed shaft 3 and the movable shaft 4 in a state of being separated, so that the belt 2 is always in a taut state.
