It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the present application is not limited to the specific embodiments of the following disclosure.

[0031] Embodiment 1, as Figure 1-4 As shown, the present application provides a sterile hemodialysis catheter fixing sleeve, the fixing sleeve comprising:

[0032] A first fixing sleeve 1 and a second fixing sleeve 2;

[0034] The fixing mechanism 3 includes a first slide plate 301, a second slide plate 302, a first set of rods 303, a second set of rods 304 and a pressing plate 305. The first slide plate 301 is slidably arranged inside the second slide plate 302. The second slide plate 302 is connected to the first set of rods 303. The second set of rods 304 is movably embedded in the inner wall of the first set of rods 303. The pressing plate 305 is connected to a side of the second set of rods 304 away from the first set of rods 303. The second slide plate 302 can slide outside the first slide plate 301. By sliding the second slide plate 302 The position of the squeezing component 309 can be changed by changing the position of the squeezing component 309. When facing different arm lengths, the catheter can be fixed in a suitable position for easy use. The second slide plate 302 and the first set of rods 303 are fixedly connected together. The second slide plate 302 moves through the first set of rods 303 to move the pressing plate 305, and further moves the elastic component 308. The second set of rods 304 can slide inside the first set of rods 303. The pressing plate 305 has a supporting and connecting function for the elastic component 308, and the pressing plate 305 is in a circular ring shape.

[0035] The screw pin 307 is disposed on the first slide plate 301 and can limit the movement of the second slide plate 302. After the second slide plate 302 moves to a suitable position, the position of the second slide plate 302 can be limited by the screw pin 307;

[0036] A plurality of threaded holes 306 are arranged in sequence on one side of the first slide plate 301, and a threaded nail 307 can be threadedly embedded in any threaded hole 306. When the second slide plate 302 is moved to a suitable position, the threaded nail 307 can be rotated and inserted into any threaded hole 306 to fix the second slide plate 302.

[0037] The extrusion component 309 is arranged on one side of the pressure plate 305. The extrusion component 309 can be a rubber gasket or a foam plate. There is no limitation here. Both have good elasticity and softness. When the extrusion component 309 is close to the catheter, the elastic force can prevent the catheter from sliding out of the pressure plate 305, and the softness protects the catheter.

The transverse axis 403 is movably embedded in the inner walls of the two convex plates 401 for flipping the first fixing sleeve 1. The two convex plates 401 can rotate around the transverse axis 403, so that the first fixing sleeve 1 can rotate. The two support plates 402 connect the transverse axis 403 and the second fixing sleeve 2 together, and further connect the first fixing sleeve 1 and the second fixing sleeve 2 together.

[0040] like Figure 1-4 As shown, the limiting mechanism 5 is arranged on the opposite side of the first fixing sleeve 1 and the second fixing sleeve 2, and the limiting mechanism 5 includes a first positioning plate 501 and a second positioning plate 502, wherein a threaded rod 503 is fixedly arranged on one side of the first positioning plate 501, and a positioning hole 505 is opened on one side of the second positioning plate 502. After the first fixing sleeve 1 is flipped over, the position of the first fixing sleeve 1 is fixed by the limiting mechanism 5, and the positioning hole 505 facilitates the insertion of the threaded rod 503.

[0041] like Figure 1-4 As shown, the outer surface of the threaded rod 503 is threadedly provided with a sleeve 504 for limiting the movement of the first positioning plate 501, and the threaded rod 503 is movably embedded in the positioning hole 505. When the threaded rod 503 is inserted into the positioning hole 505, the positions of the first positioning plate 501 and the second positioning plate 502 are fixed by rotating the sleeve 504.

[0042] like Figure 1-4 As shown, sponges 506 are provided on the inner walls of the first fixing sleeve 1 and the second fixing sleeve 2. When the arm is inside the first fixing sleeve 1 and the second fixing sleeve 2, the softness of the sponge 506 protects the arm to prevent the arm from being damaged due to prolonged squeezing.

[0043] like Figure 1-4As shown, the connecting plate 310 is arranged on one side of the second fixing sleeve 2, and fixing parts 311 for fixing the dialysis catheter are arranged on both sides of the connecting plate 310. The connecting plate 310 has a supporting function for the fixing part 311. The fixing part 311 can be a bandage or a Velcro, which is not limited here, and the catheter is fixed for the second time.

[0044] like Figure 1-4 As shown, an elastic component 308 is arranged inside the first set of rods 303 to push the second set of rods 304 to move. The elastic component 308 can be a spring or a metal spring, and there is no limitation here. The elastic component 308 is inside the first set of rods 303 and its position can be moved to push the second set of rods 304 by elastic force.

[0045] Working principle: When in use, the fixed sleeve is in Figure 4 As shown in the shape, the arm is placed between the first fixing sleeve 1 and the second fixing sleeve 2, and the two convex plates 401 can rotate with the horizontal axis 403 as the axis, and the first fixing sleeve 1 is rotated so that the first positioning plate 501 and the second positioning plate 502 are closely attached together. Figure 1 As shown, the threaded rod 503 passes through the positioning hole 505. At this time, the second slide plate 302 is slid to make the pressing plate 305 in a suitable position of the arm, and the catheter is placed under the squeezing component 309 and passes through the middle of the first fixing sleeve 1 and the second fixing sleeve 2. The elastic force generated by the elastic component 308 pushes the second sleeve rod 304, and further through the pressing plate 305, the squeezing component 309 makes the catheter close to the arm. At this time, one end of the catheter is on one side of the connecting plate 310, and the position of the other end of the catheter is fixed by the fixing component 311, so that the position of the catheter is fixed by the squeezing component 309 and the fixing component 311, which is convenient for use. At the same time, the position of the catheter is not easy to shift. At this time, the first fixing sleeve 1 and the second fixing sleeve 2 are fixed on the arm by rotating the sleeve 504, and the fixation of the fixer sleeve is completed. The method is simple, the fixation is firm and not easy to fall off.
