[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 As shown, an anti-falling fixing device for a tracheotomy tube comprises a fixing belt 1, a through hole 1 is provided at the center of the front end of the fixing belt 1, a plurality of evenly distributed limiting holes are provided on the left side of the front end of the fixing belt 1, and the limiting holes match the size of the positioning stud 3, a fixing block 2 is fixedly connected to the right side of the front end of the fixing belt 1, the positioning stud 3 is threadedly connected to the front end of the fixing block 2, a limiting groove 4 matching the fixing belt 1 is provided at the right end of the fixing block 2, and the limiting groove 4 runs through the left end of the fixing block 2;

[0026] During the actual operation, it is necessary to wrap the fixing belt 1 around the patient's neck so that the center position of the fixing belt 1 is aligned with the patient's tracheotomy site, and then pass the end of the fixing belt 1 with the limiting hole through the limiting groove 4. When the surrounding range of the fixing belt 1 meets the requirements, rotate the positioning stud 3 so that the positioning stud 3 passes through the limiting hole on the fixing belt 1 for fixation.

[0027] like Figure 2 , Figure 4 and Figure 5As shown, a fixing component 5 is fixedly connected to the center position of the front end of the fixing belt 1, and the fixing component 5 includes a threaded column 51, and the rear end of the threaded column 51 is fixedly connected to the front end of the fixing belt 1, and a guide tube 52 is fixedly connected to the center position of the rear end of the inner surface of the threaded column 51, and the left and right parts of the outer surface of the guide tube 52 are fixedly connected to the second fixing block 53, and the rear end of the inner surface of the threaded column 51 is fixedly connected to two symmetrically distributed tracks 54, and the inner surface of the track 54 is slidably connected to the sliding block 55, and the side of the sliding block 55 away from the guide tube 52 is an inclined surface, and a spring 56 is fixedly connected between the second fixing block 53 and the sliding block 55, and a silicone card block 57 is fixedly connected to the front end of the sliding block 55, and a rotating cover 58 is threadedly connected to the outer surface of the threaded column 51. The rotating cover 58 includes a main body 581, and the inner surface of the main body 581 is threadedly connected to the outer surface of the threaded column 51, and a retaining ring 582 is fixedly connected to the inner surface of the main body 581;

[0028] When the main body 581 is rotated, the retaining ring 582 inside the main body 581 will move downward along the inclined surface of the sliding block 55, and the sliding block 55 will be squeezed during the movement. The side of the sliding block 55 away from the guide tube 52 is an inclined surface. At this time, the sliding block 55 will squeeze the spring 56. At this time, the silicone block 57 on the top of the sliding block 55 will move toward the middle of the inner cavity of the guide tube 52, thereby fixing the catheter.

[0029] like Figure 2 and Figure 3 As shown, the center position of the rear end of the fixing belt 1 is movably connected with a leak-proof component 6, and the leak-proof component 6 includes a Velcro hook surface 61. The front ends of the two Velcro hook surfaces 61 are fixedly connected to the rear end of the fixing belt 1. The rear end of the Velcro hook surface 61 is movably connected with a Velcro fur surface 62. The rear ends of the two Velcro fur surfaces 62 are commonly fixedly connected with a sponge pad 63. The front end of the sponge pad 63 is provided with a through hole 2 which is the same size as the through hole 1. When the sponge pad 63 needs to be replaced, it is only necessary to remove the fixing belt 1, tear off the sponge pad 63, and replace it.

[0030] The Velcro hook surface 61 and Velcro hair surface 62 used in this solution are conventional designs of the prior art. The Velcro hook surface 61 is a surface with tiny hook-like components, and the Velcro hair surface 62 is a surface with tiny hair-like components. When the two materials come into contact, the hook-like components will grab the hair-like components to achieve a tight combination.

[0031] The working principle of the utility model is as follows: first, the fixing belt 1 is wrapped around the patient's neck so that the center position of the fixing belt 1 is aligned with the patient's tracheotomy site, and then the end of the fixing belt 1 with the limiting hole is passed through the limiting groove 4. When the surrounding range of the fixing belt 1 meets the requirements, the positioning stud 3 is rotated to make the positioning stud 3 pass through the limiting hole on the fixing belt 1 for fixation, and then the catheter is inserted into the guide tube 52. Then, when the main body 581 is rotated, the retaining ring 582 inside the main body 581 will move downward along the inclined surface of the sliding block 55, and the sliding block 55 will be squeezed during the movement. The side of the sliding block 55 away from the guide tube 52 is an inclined surface. At this time, the sliding block 55 will squeeze the spring 56, and the silicone block 57 on the top of the sliding block 55 will move toward the middle of the inner cavity of the guide tube 52, thereby fixing the catheter. When the sponge pad 63 needs to be replaced, only the fixing belt 1 needs to be removed, and the sponge pad 63 can be torn off and replaced.

[0032] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model.
