[0002] The function of the dialysis tube fixation device for nephrology is to ensure that the dialysis tube remains in the correct position during treatment, reduce accidental movement and skin damage, and improve the patient's treatment effect and comfort.

[0003] Although current technology has many advantages, its disadvantage is that, because the body shape and blood vessel size of patients are slightly different, it is difficult for the dialysis tube to be tightly combined with the fixing device, which makes the dialysis tube loose and limits the scope of use of the fixing device. At the same time, using a single tape to position the dialysis tube may require applying greater pressure, resulting in local skin pressure, which may cause discomfort, skin damage or even ulcers. In addition, if the position of the line needs to be adjusted or the line needs to be inspected or replaced, the single fixing tape may need to be completely removed and then re-fixed, which increases the complexity and time cost of the operation.

The tights can be connected to the adhesive layer instead of the skin, thereby avoiding the adhesive layer from pulling the skin when removing.

[0009] As a preferred embodiment, two springs are fixedly connected to the top of the positioning block 1, and the tops of the two springs are fixedly connected to the positioning block 2. The springs provide power for the reverse movement of the positioning block 2, so that the positioning block 2 moves in the reverse direction.

[0010] As a preferred embodiment, the adhesive layer is composed of an acrylic adhesive, which can connect the fixing block to the tights.

[0011] As a preferred embodiment, the two springs are movably sleeved on the outer surfaces of the two limit rods, and a pull rod is fixedly connected to the top of the second positioning block, and the pull rod provides power to the second positioning block.

[0015] 2. In the utility model, when in use, the doctor manually pulls the pull rod, so that the pull rod drives the positioning block 2 to move, and the positioning block 2 pulls the two limit rods and the two springs on the positioning block 1, so that the two springs obtain elastic potential energy. However, although the limit rod moves, it still remains embedded in the positioning block 1. Then the doctor passes the medical tube through the middle gap between the positioning block 1 and the positioning block 2. The doctor then releases the pull rod, and the two springs release the elastic potential energy, so that the positioning block 2 moves in the opposite direction and clamps the medical tube to fix one end of the medical tube. The positioning block 2 also clamps one end of the medical tube, avoiding the use of one tape to fix, resulting in applying greater pressure, causing local skin pressure, causing patient discomfort, skin damage or even ulcers, and no need to re-fix when checking or replacing the pipeline, reducing the complexity and time cost of the operation.

[0024] like Figure 1-4 As shown, the outer surface of the tights 1 is fixedly connected with a positioning block 14, and the inner surfaces of the plurality of positioning blocks 14 are movably embedded with two limit rods 15, thereby avoiding the use of a single tape for fixing, resulting in a large pressure, causing local skin compression, causing patient discomfort, skin damage or even ulcers, and when checking or replacing the pipeline, there is no need to re-fix, thereby reducing the complexity and time cost of the operation.

[0025] like Figure 1-4 As shown, the outer surfaces of the multiple clamping blocks 11 are provided with medical tubes 19, and the multiple slide bars 12 are movably embedded in the inner surfaces of the multiple limit grooves 13. The limit grooves 13 can limit the movement trajectory of the slide bars 12, thereby avoiding the slide bars 12 from derailing and affecting the use of the equipment.

[0026] like Figure 1-4As shown, the fixing block 3 is arranged on the outer surface of the tights 1, and an adhesive layer 4 is arranged on the bottom of the fixing block 3. The tights 1 can replace the skin and connect with the adhesive layer 4, so as to avoid the adhesive layer 4 pulling the skin when removing it, which causes discomfort to the patient.

[0027] like Figure 1-4 As shown, two springs 16 are fixedly connected to the top of the positioning block 14, and the tops of the two springs 16 are fixedly connected to the positioning block 2 17. The spring 16 provides power for the reverse movement of the positioning block 2 17, so that the positioning block 2 17 moves in the reverse direction and clamps the medical tube 19.

[0028] like Figure 1-4 As shown, the adhesive layer 4 is made of an acrylic adhesive, which can connect the fixing block 3 to the tights 1 so that the fixing block 3 is fixed on the tights 1 .

[0029] like Figure 1-4 As shown, two springs 16 are movably sleeved on the outer surfaces of the two limit rods 15, and a pull rod 18 is fixedly connected to the top of the second positioning block 17. The pull rod 18 provides power for the second positioning block 17 to move the second positioning block 17.

[0030] like Figure 1-4 As shown, the two limit rods 15 are fixedly connected to the bottom of the second positioning block 17, and the pull rod 18 is in a U-shape, which is more convenient to operate, can provide better gripping force, and reduce labor intensity during use.

[0031] Working principle: This device is a dialysis tube fixing device for nephrology. When in use, the doctor manually pulls the pull rod 18, so that the pull rod 18 drives the positioning block 17 to move, and the positioning block 17 pulls the two limit rods 15 and the two springs 16 on the positioning block 1 14, so that the two springs 16 obtain elastic potential energy. However, although the limit rod 15 moves, it still remains embedded in the positioning block 1 14. Then the doctor passes the medical tube 19 through the gap between the positioning block 14 and the positioning block 2 17. The doctor then releases the pull rod 18, and the two springs 16 release the elastic potential energy, causing the positioning block 2 17 to move in the opposite direction and clamp the medical tube 19 to fix one end of the medical tube 19. The patient then puts on the tights 1, and the doctor selects the position where the medical tube 19 is placed, and cuts a notch 2 at the position where the medical tube 19 passes through the tights 1. Then, the fixing block 3 is attached to the tights 1 using the adhesive layer 4, and then the medical tube 19 passes through the fixing block 3 and the tights 1 and is connected to the patient's body. Manually rotate the operating rod 7 to move the operating rod 7 on the inner surface of the operating groove 8 on the fixed block 3, and drive the rotating block 6 to rotate in the working groove 5. The rotating block 6 drives multiple sliders 10 to rotate through the slide groove 9, and the multiple sliders 10 drive multiple clamping blocks 11 to rotate. The multiple clamping blocks 11 drive multiple slide bars 12 to move on the inner surfaces of multiple limit grooves 13. Finally, the multiple clamping blocks 11 fit tightly with the medical tube 19 by making circular motions and fix the other end of the medical tube 19, thereby fixing medical tubes 19 of different sizes, avoiding the loosening of the medical tube 19 caused by the incompatibility between the medical tube 19 and the fixing device, and ensuring the health of the patient. The positioning block 2 17 also clamps one end of the medical tube 19, avoiding the use of a single tape to fix, resulting in a large pressure, resulting in local skin pressure, causing patient discomfort, skin damage or even ulcers. When checking or replacing the pipeline, there is no need to re-fix it, reducing the complexity and time cost of the operation.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
