[0026] Embodiment

[0027] Please refer to Figures 1 - 3 , this embodiment provides an internal fistula puncture tourniquet and blood line tube fixing device, which includes an arm ring 1 having two free ends and a blood line tube fixing assembly arranged on the arm ring 1. The number of blood line tube fixing assemblies is at least two. Since generally only the arterial end blood line tube and the venous end blood line tube need to be fixed, the number of blood line tube fixing assemblies is preferably two. The arm ring 1 is provided with a limiting clamping rod 2, and a plurality of limiting clamping holes 3 are arranged at intervals along the extending direction of the arm ring 1; the arm ring 1 of this embodiment can be made of rubber material. When in use, the arm ring 1 is wound into a ring shape, and the limiting clamping rod 2 passes through a limiting clamping hole 3.

[0028] During actual use, as Figure 1 and Figure 2 shown, according to the thickness and size of the arms of different patients, wind the arm ring 1 around the patient's arm, and pass the limiting clamping rod 2 through a limiting clamping hole 3 at the corresponding position to complete the wearing. Since the arm ring 1 can adjust the tightness of the arm ring 1 according to the different positions where the limiting clamping rod 2 is clamped in the limiting clamping hole 3, when used as an internal fistula puncture tourniquet, only need to tighten the arm ring 1 during internal fistula puncture, and bind the arm ring 1 to the patient's arm to achieve the function of the tourniquet.

[0029] After successful puncture, adjust the tightness of the arm ring 1 according to the size of the patient's arm, and then fix the arterial end blood line tube and the venous end blood line tube connected to the hemodialysis machine through two blood line tube fixing assemblies respectively.

[0030] In this way, through the function of the adjustable tightness of the arm ring 1, it has both the function of a tourniquet and the function of fixing the blood line tube, and can be used according to the individual differences of patients, improving the comfort and safety of patients during dialysis. Nurses are simple and easy to use during the operation. Only need to adjust the tightness of the arm ring 1 to perform puncture. When separating the blood return during machine collection, only need to loosen the arm ring 1 to loosen the arm, saving time and improving work efficiency. The blood line tube fixing assemblies on the arm ring 1 respectively place the static and dynamic ends of the blood line tube. When the patient moves the internal fistula arm, the blood line tube will not fall to the ground due to gravity, reducing the incidence of infection and preventing the occurrence of major bleeding events caused by the puncture needle falling out of the internal fistula blood vessel due to unstable fixation.

[0031] As Figures 1 - 2 shown, in some embodiments of the present utility model, the shape of the limiting clamping rod 2 along its axial cross-section is T-shaped, so that it is convenient for the limiting clamping rod 2 to pass through the limiting clamping hole 3 and be clamped on the arm ring 1, reducing the risk of the limiting clamping rod 2 falling off from the limiting clamping hole 3 and improving the stability of the arm ring 1 after wearing.

[0032] As Figures 1 - 2 shown, in some embodiments of the present utility model, a first magnetic attraction block 4 is provided at the outer end of the arm ring 1. The first magnetic attraction block 4 in this embodiment can be a magnet. A magnetic strip 5 is provided along the extending direction of the arm ring 1 at the inner end of the arm ring 1. The first magnetic attraction block 4 is magnetically connected to the magnetic strip 5. When the patient's arm is relatively thin, there is a relatively long position between the free end of the outer end of the arm ring 1 and the limiting clamping rod 2, and this part is prone to warping, increasing the risk of accidental touch during the use of the arm ring 1. By providing the first magnetic attraction block 4 and the magnetic strip 5, as Figure 1 and Figure 2 , after the arm ring 1 is worn well, the first magnetic attraction block 4 is magnetically connected to the magnetic strip 5, and the free end of the outer end of the arm ring 1 is adsorbed on the arm ring 1, which can prevent the free end of the outer end of the arm ring 1 from warping, thereby reducing the risk of accidental touch during the use of the arm ring 1.

[0033] As Figures 1 - 3 shown, in some embodiments of the present utility model, the blood conduit fixing assembly includes two semi-circular fixing buckles 6. One end of the two fixing buckles 6 is rotatably connected through a rotating shaft 7, and the other end of the two fixing buckles 6 is a free end; one fixing buckle 6 is provided on the outer side wall of the arm ring 1. A torsion spring 8 is sleeved on the rotating shaft 7. One end of the torsion spring 8 is connected to one fixing buckle 6, and the other end of the torsion spring 8 is connected to the other fixing buckle 6.

[0034] In the present utility model, by providing two semi-circular fixing buckles 6, when fixing the blood conduit, the fixing buckle 6 above can be rotated along the rotating shaft 7 to make the two fixing buckles 6 rotate and open, which is convenient for moving the blood conduit into the space between the two fixing buckles 6. Under the torsion force of the torsion spring 8, the two fixing buckles 6 can be rotated and clamped together, so that it is convenient to clamp and fix the blood conduit through the two fixing buckles 6, and it is also convenient to take out the blood conduit from between the two fixing buckles 6 after use.

[0035] As Figures 1 - 3 shown, in some embodiments of the present utility model, second magnetic attraction blocks 9 are provided at the free ends of the two fixing buckles 6, and the second magnetic attraction blocks 9 on both sides are magnetically connected to each other. The second magnetic attraction blocks 9 in this embodiment can be magnets. In the present utility model, by providing the second magnetic attraction blocks 9, after the blood conduit is clamped and fixed, the second magnetic attraction blocks 9 on both sides are magnetically connected to each other, so that the stability of the connection between the free ends of the two fixing buckles 6 can be improved, and the risk of the blood conduit falling off from between the two fixing buckles 6 can be reduced.

[0036] As Figures 1 - 3 shown, in some embodiments of the present utility model, the free ends of both fixing buckles 6 are provided with guiding arc-shaped pieces 10 facing outward. By providing the guiding arc-shaped pieces 10, as Figure 3 shown, the two guiding arc-shaped pieces 10 form an outward-facing V-shaped groove. When fixing the blood circuit tube to the two fixing buckles 6, the blood circuit tube can be moved to the position of the V-shaped groove, and then the blood circuit tube is pushed towards the side of the rotating shaft 7. Under the thrust, it is convenient to make the two fixing buckles 6 rotate and open, so that it is convenient to push the blood circuit tube between the two fixing buckles 6 for snap-fitting and fixing.

[0037] As Figures 1 - 3 shown, in some embodiments of the present utility model, the fixing buckle 6 near the arm ring 1 is provided with a mounting seat 11, and further includes a fixing bolt 12. The fixing bolt 12 passes through the arm ring 1 and is threadedly connected to the mounting seat 11. By providing the fixing bolt 12, the present utility model facilitates the installation of the blood circuit tube fixing assembly on the arm ring 1 through the fixing bolt 12, and also facilitates the disassembly of the blood circuit tube fixing assembly from the arm ring 1 for replacement.
