[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] In this embodiment, Figure 1-5 The utility model includes an elastic band 1 for wrapping around the patient's body. The elastic band 1 can be made of elastic nylon material. Velcro 2 is sewn and fixed on both sides of the elastic band 1. The arrangement of the Velcro 2 allows the elastic band 1 to be wrapped around the body of a patient of any size. The two ends of the elastic band 1 can then be fixed with the Velcro 2. The entire installation method is simple and convenient, and the subsequent disassembly is flexible.

[0028] A sliding belt 3 is fixedly mounted on the surface of the elastic belt 1, a support frame 4 is movably mounted on the outside of the sliding belt 3, and an elastic component 5 is provided on the outside of the support frame 4 for fixing on the sliding belt 3;

[0029] The tensioning assembly 5 includes a sliding groove 501 formed inside the support frame 4. A sliding rod 502 is fixedly installed in the inner cavity of the sliding groove 501. A clamping plate 503 for clamping the sliding belt 3 is movably installed at one end of the sliding rod 502. An adjusting rod 504 with a threaded surface is threadedly connected to the bottom of the clamping plate 503. A control groove 505 is formed at the bottom of the support frame 4. A control rod 506 is movably installed in the inner cavity of the control groove 505, and one end of the control rod 506 is fixed to one end of the adjusting rod 504.

[0030] The support frame 4 is manually pushed to move on the sliding belt 3. The specific moving position depends on the position of the hemodialysis catheter inserted into the patient's body. When the support frame 4 moves to the appropriate position, the control rod 506 inside the control slot 505 is rotated. The control slot 505 is used to isolate the control rod 506 to prevent the control rod 506 from being accidentally touched, thereby ensuring the stability of the control rod 506. When the control rod 506 rotates, it can drive the adjustment rod 504 to rotate synchronously, and then the adjustment rod 504 will cooperate with the sliding rod 502 to drive the clamping plate 503 to move. In this way, the clamping plate 503 can be used to cooperate with the support frame 4 to fix its position on the sliding belt 3. The whole operation process is simple and convenient.

[0031] The outside of the elastic component 5 is provided with a retaining component 6 for fixing the hemodialysis catheter;

[0032] The retaining assembly 6 includes a placement plate 601 fixed to the elastic assembly 5. The placement plate 601 has a retention groove 602 for placing the hemodialysis catheter. The middle of the retention groove 602 has a lifting groove 603 with a threaded inner wall. The inner cavity of the lifting groove 603 is threadedly connected to a positioning rod 604. A circular protective plate 605 is fixedly mounted on one end of the positioning rod 604.

[0033] After the hemodialysis catheter is placed in the retaining groove 602, it can be threadedly connected to the lifting groove 603 inside the placement plate 601 through the positioning rod 604 on the protective plate 605, and then the hemodialysis catheter can be squeezed and fixed by the back of the protective plate 605. Since the position of the protective plate 605 is adjustable, it can be fixed even when facing hemodialysis catheters of different sizes, thus ensuring the stability of the installation of the hemodialysis catheter. In addition, the protective plate 605 can block external objects, thereby preventing objects from squeezing the hemodialysis catheter, thereby improving the safety of the hemodialysis catheter.

[0034] The front surface of the protective plate 605 is fixedly mounted with a number of semicircular pressure-resistant blocks 7 for pressure resistance. The pressure-resistant blocks 7 are made of elastic rubber material. The back surface of the protective plate 605 is provided with a pressure-resistant member 8.

[0035] The pressure-resistant member 8 includes a plurality of protective sleeves 801 fixed to the outside of the pressure-resistant block 7 in an annular arrangement. The interior of the protective sleeves 801 is filled with foam particles 802, and a cotton body-fitting layer 803 is fixed to the outside of the protective sleeves 801.

[0036] The plurality of anti-compression blocks 7 can enhance the external protective force of the protective plate 605 and further improve the compressive strength of the protective plate 605. The provision of the anti-compression member 8 allows the anti-compression block 7 to be cushioned by the foam particles 802 inside the protective cover 801 after being squeezed, while the body-fitting layer 803 is in direct contact with the patient's body surface. In this way, the use of multiple anti-compression members 8 can form a buffer space between the protective plate 605 and the patient's body surface, greatly improving the protection strength of the hemodialysis catheter.

[0037] The bottom of the placement plate 601 is provided with two receiving slots 9. A retaining spring 10 is fixedly installed in the inner cavity of each receiving slot 9. A strap 11 with a surface having multiple colors is fixedly installed at one end of each retaining spring 10. The multiple color segments on the surface of the strap 11 are arranged at equal intervals. A button 12 is fixedly installed at one end of the strap 11.

[0038] When the installation of the hemodialysis catheter is completed, the belt 11 can be wrapped around one end of the hemodialysis catheter, and then the button 12 can be used to fix the belt 11 on one end of the hemodialysis catheter. Subsequently, when the position of the hemodialysis catheter changes, the belt 11 will be moved synchronously, and one end of the belt 11 will pull the retaining spring 10 inside the storage slot 9. In this way, the position of the hemodialysis catheter can be reinforced again by using the retaining spring 10 in conjunction with the belt 11, and the staff can directly observe the position of the belt 11 when it is pulled out of the storage slot 9, and then confirm whether the hemodialysis catheter has position deviation according to the color on the belt 11, thereby realizing a warning function.
