Description

Technical Field

[0001] The invention relates to the technical field of blood purification kidney dialysis, in particular to a multi-stage filtering device for blood purification kidney dialysis. Background Art

[0002] Hemodialysis refers to an artificial kidney treatment method that uses special instruments to replace the function of the kidneys. Through hemodialysis, excessive toxic urea nitrogen, creatinine and other toxic substances in the blood are excreted from the body through the machine, replacing the function of the human kidneys. Many patients with chronic uremia rely on hemodialysis to achieve long-term survival.

[0003] In order to effectively avoid blood coagulation during the filtration process, a multi-stage filtration device for blood purification renal dialysis has emerged (see patent number: 202123127444.6 for details), which specifically relates to the field of blood purification technology, including a liquid storage tank and a top cover, a liquid storage cylinder is provided inside the liquid storage tank, a filter disc is fixedly installed inside the liquid storage cylinder, and the filter disc includes an alkaline filter layer, an acidic filter layer, a neutral filter layer and a semipermeable membrane from top to bottom, a hollow connecting column is fixedly connected to the middle position of the lower surface of the liquid storage cylinder, a first pulley is provided on the hollow connecting column, and a plurality of balls are movably installed on the upper surface of the inner part of the liquid storage tank, a drive motor is provided on the right side of the liquid storage tank, and a second pulley is sleeved on the output end of the drive motor, and a transmission belt is provided on the outer sides of the first pulley and the second pulley.
