DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Embodiment one:

[0025] Please refer to Figure 1 - Figure 4 As shown in the figure, an anti-falling hemodialysis catheter fixing device comprises:

[0026] Support rod 1;

[0027] One end of the support rod 1 is provided with a connecting rod 4, the top middle part of the connecting rod 4 is provided with a fixed rod 5, the top end of the fixed rod 5 is provided with a connecting pipe 6, the connecting pipe 6 is movably provided with an insert rod 7, one end of the insert rod 7 is provided with a support plate 11, four fixed structures 8 are equidistantly arranged on the upper part of one end of the support plate 11, a fixed seat 10 is arranged on the upper part of the other end of the support plate 11, and the outer surface of the fixed seat 10 is equidistantly provided with four limiting structures 9.

[0028] The limiting structure 9 comprises a mounting plate 91, a support frame 92, a limiting block 93, a connecting block 94 and a movable column 95, two support frames 92 are arranged on both sides of the outer surface of the mounting plate 91, two limiting blocks 93 are movably connected to the outer surface of one end of the two support frames 92, two connecting blocks 94 are movably connected in the two support frames 92, and the movable column 95 is movably arranged in the two connecting blocks 94; and the mounting plate 91 is arranged on the outer surface of the fixed seat 10.

[0029] The fixed structure 8 comprises a connecting plate 81, a reinforcing block 82, a limiting seat 83 and a limiting belt 84, two reinforcing blocks 82 are arranged at the bottom end of the connecting plate 81, the limiting seat 83 is arranged at the top end of the connecting plate 81, the limiting belt 84 is sleeved on the limiting seat 83, and the reinforcing blocks 82 are arranged at one end of the support plate 11.

[0030] As can be seen, the hemodialysis catheter is inserted between the mounting plate 91, the two support frames 92 and the movable column 95, and then the hemodialysis catheter is threaded between the two limiting blocks 93 and inserted into the limiting belt 84. The limiting belt 84 is pulled to tighten the limiting belt 84, so as to fix the hemodialysis catheter, thereby improving the fixing stability of the hemodialysis catheter. When the hemodialysis catheter is pulled, the hemodialysis catheter moves and the movable column 95 rotates in the two connecting blocks 94, thereby avoiding the friction of the pipeline.

[0031] Preferably, the bottom ends of the mounting plate 91 and the support frame 92 are provided in arc-shaped structures.

[0032] One end of the connecting plate 81 is fixedly connected to one end of the support plate 11.

[0033] The fixing structure 8 and the limiting structure 9 are installed one by one.

[0034] As can be seen, the bottom ends of the mounting plate 91 and the support frame 92 are provided in arc-shaped structures, so as to support the catheter and avoid the folding of the catheter.

[0035] Embodiment two:

[0036] Referring to Figure 4 As shown, the top end of the connecting pipe 6 is movably provided with the positioning rod 12 on both sides, the bottom end of the positioning rod 12 penetrates the top end of the connecting pipe 6 and is inserted into the penetrating rod 7, the bottom end of the support rod 1 is provided with two penetrating grooves 2, the top end of the support rod 1 is provided with a plurality of positioning holes 3 at equal intervals on both sides, and the fixing rod 5 and the support rod 1 are jointly provided with the reinforcing plate 13.

[0037] As can be seen, the support rod 1 is inserted into the hospital bed through the two penetrating grooves 2, and then fixed through the positioning hole 3. The penetrating rod 7 is pushed to slide in the connecting pipe 6. When the penetrating rod 7 moves, the support plate 11 fixedly connected with the penetrating rod 7 is displaced. The support plate 11 drives the fixed seat 10 fixedly connected thereto to displace. The fixed seat 10 drives the limiting structure 9 mounted thereon to move, so that the position of the limiting structure 9 is suitable for placing the hemodialysis catheter.

[0038] Further, the design application is applied in the process of fixing the hemodialysis catheter. First, the support rod 1 is inserted into the hospital bed through the two penetrating grooves 2, and then fixed through the positioning hole 3. Subsequently, the penetrating rod 7 is pushed to smoothly slide in the connecting pipe 6, thereby driving the support plate 11 fixedly connected with the penetrating rod 7 to displace. The movement of the support plate 11 further drives the fixed seat 10 to move together. The limiting structure 9 on the fixed seat 10 also adjusts the position, until the ideal state suitable for placing the hemodialysis catheter is reached.

[0039] Next, the hemodialysis catheter is carefully inserted into the frame formed by the mounting plate 91, the two support frames 92 and the movable column 95, while ensuring that the catheter passes through the gap between the two limiting blocks 93 and is finally placed in the limiting belt 84. At this time, gently pull the limiting belt 84, which will closely fit and fix the hemodialysis catheter, significantly enhancing the stability of the fixation;

[0040] When the hemodialysis catheter needs to be adjusted or moved, its smooth movement will make the movable column 95 flexibly rotate in the two connecting blocks 94, reducing the friction between the pipeline and the fixing device, protecting the catheter from damage and ensuring smooth use, improving the convenience and safety of the hemodialysis catheter fixation.

[0041] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
