Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a hemodialysis auxiliary device. Background Art

[0002] As we all know, 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 hollow fibers through diffusion, ultrafiltration, adsorption, and convection, clearing metabolic waste and maintaining electrolyte and acid-base balance.

[0003] In real life, when patients are sitting on a chair for hemodialysis, they often put their arms on auxiliary devices to support their arms. However, common auxiliary devices cannot adjust the posture of the patient's arms. The patient's fatigue will increase when maintaining a posture during hemodialysis, which may cause danger if they are not careful. Moreover, the auxiliary device cannot be adjusted according to the length of the patient's arm. For some patients with longer arms, the wrist and palm cannot be placed on the auxiliary device, causing the palm to hang down. The pulling force on the wrist when the palm hangs down for a long time is large, which can easily cause fatigue in the wrist. Therefore, the practicality is not good and there is room for improvement. Utility Model Content
