[0021] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0022] Example

[0023] The intra-aortic balloon counterpulsation catheter fixing band described in this embodiment is as follows: Figure 1 , Figure 2 and Figure 5As shown, it includes a fixing belt body 1 for fixing on a human body. The fixing belt body 1 is a prior art. An adhesive layer 5 for sticking on a human body is provided on the lower surface of the fixing belt body 1. When in use, the fixing belt body 1 is fixed to the surface of human skin through the adhesive layer 5. In addition, the fixing belt body 1 can also be tied to the patient's limbs for fixing by a strap;

[0024] The upper surface of the fixing belt body 1 is connected with a first bandage 4, and a through slot communicating with each other from top to bottom is provided on the first bandage 4. The movable end of the first bandage 4 is connected with a second bandage 2 which can pass through the through slot; the second bandage 2 and the first bandage 4 are integrally arranged, and the second bandage 2 and the first bandage 4 are made of elastic material, such as elastic cloth, non-woven cloth, etc.; the first bandage 4 can be fixed to the fixing belt body 1 by sewing, or the two are integrally arranged;

[0025] The width of the second bandage 2 is smaller than the width of the through slot. Figure 2 As shown, the width of the through slots distributed along the width direction of the first bandage 4 is;

[0026] An anti-skid pad is fixed on the upper surface of the connection between the second bandage 2 and the first bandage 4. The width of the anti-skid pad is smaller than the width of the through groove. The anti-skid pad includes a silicone pad 3. The silicone pad 3 is fixed at the connection between the second bandage 2 and the first bandage 4. The silicone pad 3 is made of silicone material. The silicone is medical silicone, which has good elasticity and softness. The silicone pad 3 is fixed on the second bandage 2 and the first bandage 4 by adhesive bonding.

[0027] like Figure 2 and Figure 5 As shown, the anti-skid pad is provided with a number of anti-skid grooves distributed from left to right, all of which are equally spaced and serrated. The cross-section of the latch 6 is a triangular structure, and the lower surface of the first bandage 4 is provided with a latch 6 that locks with the anti-skid grooves. When in use, firstly, since the catheter is generally made of materials such as polyethylene or polyurethane, which have good friction with silicone, when the silicone pad 3 wraps the catheter, the friction increases, and the ability to fix the pipeline is enhanced. Secondly, the anti-skid grooves can further increase the friction between the catheter and the silicone pad 3. Thirdly, the anti-skid grooves are provided on the upper surface of the silicone pad 3, which is equivalent to creases, and can further improve its bending ability and better wrap the catheter. Finally, the latch 6 on the lower surface of the first bandage 4 cooperates with the anti-skid latch and locks with each other to tightly wrap the catheter, thereby improving the ability to resist catheter loosening.

[0028] A double-sided adhesive cloth is provided between the second bandage 2 and the upper surface of the fixing belt body 1 to connect the two together, and the double-sided adhesive cloth is connected between the lower surface of the second bandage 2 and the upper surface of the fixing belt body 1; in addition, Velcro can also be used to adhere the second bandage 2 and the fixing belt body 1 together; the double-sided adhesive cloth and Velcro are both connecting components.

[0029] In actual use:

[0030] like Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the catheter is placed on the upper surface of the silicone pad 3, the movable end of the second bandage 2 is passed around the catheter and through the through groove from top to bottom, the catheter is wrapped with the silicone pad 3, and then the movable end of the second bandage 2 is pulled to the left to tighten, and after the latch 6 and the anti-slip tooth groove are locked with each other, the second bandage 2 is adhered to the upper surface of the fixing belt body 1 to complete the fixation of the catheter; the friction between the first bandage 4 and the second bandage 2 is increased by the silicone pad 3, thereby improving the fixing ability of the catheter to prevent it from loosening.

[0031] The catheter mentioned above is an intra-aortic balloon counterpulsation catheter. In addition to fixing the intra-aortic balloon counterpulsation catheter, this embodiment can also fix other medical catheters.
