[0002] Hemodialysis (HD) is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body and passes it through a dialyzer composed of countless hollow fibers. The blood and an electrolyte solution (dialysate) containing electrolytes at concentrations similar to those in the body are exchanged inside and outside the hollow fibers through the principles of diffusion, ultrafiltration, adsorption and convection, thereby removing metabolic waste from the body, maintaining electrolyte and acid-base balance, and removing excess water from the body. The entire process of returning the purified blood is called hemodialysis.

[0003] The existing hemodialysis positioner can adjust the distance between the two inner plates according to the body shape of the person through structures such as threaded rods, vertical plates, gears, limit rods, racks, and horizontal plates, thereby improving the applicable scope of use and ensuring the stability after fixation.

[0030] Hemodialysis (HD) is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body and passes it through a dialyzer composed of countless hollow fibers. The blood and an electrolyte solution (dialysate) containing electrolytes at concentrations similar to those in the body are exchanged inside and outside the hollow fibers through the principles of diffusion, ultrafiltration, adsorption and convection, thereby removing metabolic waste from the body, maintaining electrolyte and acid-base balance, and removing excess water from the body. The entire process of returning the purified blood is called hemodialysis.

[0031] In the related art, the existing hemodialysis positioner has a complex structure, is inconvenient to use, and is not easy to fix the device on the patient, which affects the working efficiency.

[0035] Specifically, the Velcro 1 18 and the Velcro 2 181 are respectively bonded to the binding belt 17 .

[0036] When in use, the convex block 14 is pulled up. Since the rod body 12 is connected to the inner bearing of the groove 111, the convex block 14 is rotated to the other side. When the convex block 14 is pulled up, the insertion rod 13 slides and rises on the inner side of the rod body 12, and then the dialysis tube 19 is placed on the inner side of the arc groove 15 at the bottom. After the placement is completed, the convex block 14 is turned back, and then the convex block 14 is pressed down to squeeze and rub the dialysis tube 19 placed on the inner side of the arc groove 15 at the top of the lower shell 11 to fix it. After completion, the screw 16 is screwed to It is inserted into the interior of the lower shell 11 and is threadedly connected with the convex block 14 to limit and fix the convex block 14. After fixation, it is put on the patient through the restraint belt 17, and then the Velcro 18 is connected with the Velcro 2 181 to complete the fixation. The device has a simple structure and is easy to fix, making it more convenient for operators to use and increasing work efficiency. It avoids the situation where the dialysis tube falls off due to insufficient stability caused by fixing it to the patient's body by tape like the original hemodialysis locator.

[0037] In some embodiments, an auxiliary component 2 is disposed on the lower shell 11 , and a concave groove 21 is opened at the top of the lower shell 11 .

[0038] A concave groove 21 is provided on the top of the lower shell 11 so that when the convex block 14 is lowered, it can be inserted into the inner side of the convex block 14 to prevent the convex block 14 from protruding, thereby increasing the aesthetics of the device and the structural stability of the convex block 14.

[0039] In some embodiments, the auxiliary component 2 further includes an inclined groove 22 opened at the bottom of the convex block 14 .

[0040] An oblique groove 22 is provided at the bottom of the convex block 14 , which makes it more convenient to connect the concave groove 21 with the convex block 14 , thereby increasing the efficiency of installation.

[0041] In some embodiments, the auxiliary component 2 further includes a placement groove 23 opened at the bottom of the lower shell 11.

[0042] A placement groove 23 is provided at the bottom of the lower shell 11 so that the placement groove 23 is in contact with the human body. The curvature of the placement groove 23 can make the lower shell 11 fit the skin better, thereby reducing the patient's discomfort.

[0043] In some embodiments, the auxiliary component 2 further includes a protective pad 24 disposed on the inner side of the placement groove 23 .

[0044] Specifically, the protection pad 24 is bonded to the inner side of the placement groove 23 .

[0045] A protective pad 24 is arranged on the inner side of the placement groove 23, so as to prevent the inner edge of the placement groove 23 from scratching the patient's skin, thereby increasing safety.

[0046] In some embodiments, the auxiliary component 2 further includes a sponge pad 25 disposed on the inner wall of the arc-shaped groove 15 .

[0047] Specifically, the sponge pad 25 is bonded to the inner wall of the arc-shaped groove 15 .

[0048] A sponge pad 25 is disposed on the inner wall of the arc-shaped groove 15 , so that the fixing effect of the dialysis tube 19 can be increased by increasing the friction force.

[0049] In some embodiments, the insertion rod 13 is rectangular in shape.

[0050] The insertion rod 13 is set to be rectangular, so that the inner side of the rod body 12 is also rectangular, which can prevent the insertion rod 13 from rotating on the inner side of the rod body 12 when the convex block 14 is rotated, resulting in the rod body 12 being unable to rotate, causing the insertion rod 13 and the inner wall of the rod body 12 to be damaged by friction, which is easy to affect the service life of the insertion rod 13 after long-term use.

[0051] In some embodiments, the convex block 14 is connected to the insertion rod 13 by bolts.

[0052] The convex block 14 is connected to the insertion rod 13 by bolts, so that when the convex block 14 is damaged or deformed later, it is convenient to replace or maintain it.
