A limiting groove 201 corresponding to the catheter body 102 is provided on the inner side of the limiting clamp 2. A breathable grid 101 is provided on the bonding plate 1.

[0028] The limiting groove 201 can conveniently limit the catheter body 102. During use, the outer wall of the catheter body 102 is squeezed against the limiting block 202, causing the first spring 204 to retract inward into the movable groove 203. When the catheter body 102 is installed inside the limiting groove 201, the first spring 204 rebounds and the limiting block 202 limits the catheter body 102, making installation convenient and the operation quick and easy during use.

[0029] Reference Figure 2 The limiting clamp 2 and the limiting block 202 are movably connected by the first spring 204. The inner side of the limiting clamp 2 is provided with a movable groove 203 corresponding to the limiting block 202. The inner side of the clamping ring 303 is fixedly installed with protective cotton 307. The clamping ring 303 and the elastic band 305 are movably installed through the rotating sleeve 304.

[0030] By pulling the movable rod 401, the movable rod 401 can slide along the inside of the storage sleeve 4, and the sliding block 406 can move along the inside of the sliding groove 405. At the same time, by rotating the rotating disk 402, the connecting plate 3 can be rotated synchronously under the transmission action of the sliding block 406 and the sliding groove 405. Through the mutual cooperation between the threaded sleeve 302 and the connecting plate 3, the clamping rings 303 can be brought closer to each other.

[0031] Reference Figure 2 The movable rod 401 is movably connected to the inner side of the storage sleeve 4 by a second spring 404. The connecting plate 3 is provided with a storage groove 403 corresponding to the rotating disk 402. A sliding block 406 is fixedly installed on the outer side of the movable rod 401.

[0032] Under the transmission action of the sliding block 406 and the sliding groove 405, the connecting plate 3 can rotate synchronously. Through the mutual cooperation between the threaded sleeve 302 and the connecting plate 3, the clamping rings 303 can be brought closer to each other. The clamping rings 303 are used for limiting the position. Through the mutual docking of the male and female buckles 306, the device can be easily worn.

[0033] In operation, this invention allows for convenient positioning of the catheter body 102 via the limiting groove 201. During use, the outer wall of the catheter body 102 is compressed against the limiting block 202, causing the first spring 204 to retract inwards towards the movable groove 203. When the catheter body 102 is installed inside the limiting groove 201, the rebound of the first spring 204 allows for positioning by the limiting block 202, facilitating installation. Operation is convenient and quick. By pulling the movable rod 401, the movable rod 40... 1. It can slide along the inside of the storage sleeve 4, so that the sliding block 406 can move along the inside of the sliding groove 405. At the same time, the rotating disk 402 can rotate, and under the transmission action of the sliding block 406 and the sliding groove 405, the connecting plate 3 can rotate synchronously. Through the mutual cooperation between the threaded sleeve 302 and the connecting plate 3, the clamping rings 303 can be brought closer to each other. The clamping rings 303 are used for limiting, and the male and female buckles 306 are connected to each other, so that the device can be easily worn on the patient's waist or legs, making the fixation process more convenient.

[0034] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model.
