Abstract

The invention relates to the technical field of medical instruments, in particular to an upper limb fixing frame for hemodialysis. The upper limb fixing frame for hemodialysis comprises a base, wherein retractable rods are arranged on the upper side of the base transversely and symmetrically, a fixing plate is arranged at the upper end of each retractable rod, and a rotating base is arranged on the lower side of the fixing plate; a lifting device is arranged on the rotating base, a round hole is formed in the middle of the base, the lower end of the lifting device penetrates through the roundhole and is connected with a fixing device, and the fixing device comprises a fixing box; a connecting plate is arranged in the fixing box, a piston is arranged outside the connecting plate, and the lower end of the lifting device extends into the fixed box and is connected with the connecting plate; the lower end of the fixed box is provided with a sucker; a vent pipe is arranged in the box wallof the fixing box; one end of the vent pipe is communicated with the sucker, and the other end of the vent pipe is communicated with the upper portion of the fixing box. According to the structural arrangement of the upper limb fixing frame, not only can the height of the upper limb fixing frame be adjusted, the comfort degree is high, but also the placing stability, the safety and the practicability are high.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a hemodialysis upper limb fixation frame. Background technique [0002] Hemodialysis (HD) is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains the blood from the body to the outside of the body through a dialyzer composed of countless hollow fibers. The blood and the electrolyte solution (dialysate) with a similar concentration to the body are exchanged through diffusion / convection inside and outside the hollow fibers. , remove metabolic waste from the body, maintain electrolyte and acid-base balance; remove excess water from the body at the same time, and return the purified blood to the entire process called hemodialysis. [0003] The Chinese patent authorization announcement number is CN 206822889 U, which discloses a hemodialysis upper limb fixation frame. The design enables the patient to move to a certain extent du...
