[0035] Specifically, the clamping assembly includes a slide groove 7, which is opened on both sides of the interior of the mounting block 2. The interior of the slide groove 7 extends to the interior of the sleeve hole and is slidably connected to a slide rod 8. The clamping block 3 is fixedly connected to one end of the slide rod 8 in the sleeve hole. The end of the slide rod 8 located in the slide groove 7 is fixedly connected to a disc 9. A first spring 10 is arranged outside the slide rod 8 and between the disc 9 and the inner wall of the mounting block 2. The top of the disc 9 extends to the top of the mounting block 2 and is fixedly connected to a push rod 11. The push rod 11 is connected to the slide groove 7. The sliding connection and the adjustment component include an insert block 13, which is slidably connected to one side of the inner part of the side block 4.

The protection of the protective spring 22 can effectively prevent the part of the tube body 1 outside the patient's body from bending due to arm movement or bedding squeezing at night, thereby further improving the safety of the device.

[0037] Specifically, one end of the two elastic bands 6 extending to the outside of the side block 4 is fixedly connected to a connecting plate 17, and the two connecting plates 17 are respectively symmetrically provided with clamping holes 19 on the inside and symmetrically fixedly connected with clamping blocks 18 on the outside, and the clamping holes 19 and the clamping blocks 18 cooperate with each other.

[0038] Through the above technical solution, the two elastic bands 6 can be connected by cooperating between the provided clamping hole 19 and the clamping block 18, so as to be tied tightly outside the patient's body. The clamping of the clamping block 3 can effectively prevent the tube body 1 from moving freely in the patient's body, thereby improving the patient's comfort.

[0039] Specifically, a torsion spring is provided at the rotation connection between the winding roller 5 and the side block 4, the top of the push rod 11 extends to the top of the mounting block 2 and is fixedly connected with a push block, and the outside of the insert block 13 extends to the outside of the side block 4 and is fixedly connected with a pull block.

[0040] Through the above technical solution, the torsion spring can automatically retract the elastic bands 6 when the two elastic bands 6 are loosened, thereby improving practicality.

[0041] Specifically, the outside of the clamping block 3 is an arc-shaped structure, and the inner sides of the two clamping blocks 3 are fixedly connected with anti-slip pads made of rubber material. Two groups of drainage holes 20 are equidistantly opened on the side of the outside of the tube body 1 away from the mounting block 2. The top of the tube body 1 is fixedly connected with a connecting head 23, and the outer side of the connecting head 23 is fixedly connected with a connecting tube 24.

[0042] Through the above technical solution, the arc-shaped clamping block 3 can better fit the outer wall of the tube body 1 when clamping the tube body 1, thereby improving the clamping stability.

[0043] When in use, before using the tube body 1, first pass the tube body 1 through the two collars 21 and the protection spring 22, then push the two push rods 11 to both sides, pull the clamping block 3 to both sides through the disc 9 and the slide rod 8, and stretch the first spring 10 at the same time, then pass the tube body 1 through the mounting block 2, and then release the push rod 11. Under the rebound force of the first spring 10, the two clamping blocks 3 can be pushed to clamp the tube body 1, and the friction force of the anti-slip pad inside the clamping block 3 can prevent the mounting block 2 from sliding freely outside the tube body 1, and then pull the plug block 13 to drive the slider 14 on the limit rod 1. 5, and squeeze the second spring 16, so that the plug block 13 is separated from the limit of the insertion hole 12, and then the two connecting plates 17 on the outside of the side block 4 are pulled out to pull the elastic band 6 out, and the plug block 13 is loosened after the elastic bands 6 on both sides are pulled out to a suitable length. The rebound force of the second spring 16 can drive the plug block 13 to rebound, so that the plug block 13 is inserted into the corresponding insertion hole 12 to achieve the limit of the elastic band 6. The plug block 13 and the insertion hole 12 cooperate with each other to adapt to patients of different body shapes, thereby improving the flexibility and adaptability of the device. Then, the elastic band 6 is stretched around both sides of the patient's body until the two connecting plates 17 are close to each other, and then the clamping block 18 is inserted into the corresponding clamping hole 19, so that the elastic band 6 can cooperate with the two clamping blocks 3 to limit the tube body 1 to the outside of the patient's body, thereby preventing the patient from unconsciously pulling out the catheter during sleep, causing severe pain in the body, and requiring the catheter to be reinserted into the patient's body, which reduces the patient's medical experience. The protection of the protective spring 22 can effectively prevent the part of the tube body 1 outside the patient's body from bending due to arm movement or bedding squeezing at night. The safety of the device is further improved. The two elastic bands 6 can be connected by cooperating with the clamping hole 19 and the clamping block 18, so as to be tied to the outside of the patient's body. The clamping of the clamping block 3 can effectively prevent the tube body 1 from moving freely in the patient's body, thereby improving the patient's comfort. The torsion spring can automatically retract the elastic band 6 when the two elastic bands 6 are loosened, thereby improving the practicality. The arc-shaped clamping block 3 can better fit the outer wall of the tube body 1 when clamping the tube body 1, thereby improving the clamping stability.
