Technical Field

[0001] The utility model relates to the field of hemodialysis nursing brackets, in particular to a hemodialysis nursing bracket. Background Art

[0002] Hemodialysis (HD) is a renal replacement therapy for patients with acute and chronic renal failure. It drains blood from the body and passes it through a dialyzer composed of countless hollow fibers. Blood and a solution containing electrolytes similar to those in the body (dialysate) exchange substances within and outside the fibers through diffusion, ultrafiltration, adsorption, and convection. This process removes metabolic waste, maintains electrolyte and acid-base balance, and removes excess water. The purified blood is then returned to the body. This process requires long-term, fixed treatment, typically requiring three sessions per week, each lasting approximately four hours.

[0003] During hemodialysis, the patient's fistula-side limb needs to be relatively fixed to ensure the stability of the dialysis circuit. However, traditional chairs or hospital beds often do not have upper limb fixation devices specifically designed for hemodialysis, which makes it easy for patients to move their arms during dialysis, affecting the dialysis effect. Leaving the arm hanging in the air for a long time or improperly fixed may also cause numbness, pain, or increased fatigue in the patient's arm. Traditional fixation methods may not be able to be personalized according to the patient's arm size and shape, resulting in unstable fixation or reduced comfort.

[0004] In this regard, in response to this technical problem, the present application proposes a hemodialysis care bracket. Utility Model Content
