Technical Field

[0001] The utility model relates to the technical field of auxiliary medical equipment, in particular to an adjustable upper limb fixing frame. Background Art

[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 through a dialyzer composed of countless hollow fibers. The blood and the electrolyte solution (dialysate) containing a concentration similar to that of the body are exchanged inside and outside the hollow fibers through diffusion, ultrafiltration, adsorption and convection principles to remove metabolic waste from the body, maintain electrolyte and acid-base balance, remove excess water from the body, and return the purified blood. The whole process is called hemodialysis.

[0003] Its main function is to fix the patient's upper limbs to ensure safety and comfort during dialysis. This type of fixation frame can usually be adjusted according to the patient's needs to adapt to different body sizes and postures. It can help patients maintain upper limb stability, reduce discomfort and movement, and also facilitate medical staff to perform puncture and monitoring. The use of an adjustable upper limb fixation frame can improve the efficiency and quality of hemodialysis and provide patients with a better treatment experience.
