step S2: the blood enters the box body (1), toxins and metabolic waste in the blood are removed under the action of the filtering component, electrolyte and acid-base balance are maintained, and the filtered blood enters the inner cavity of the reverse osmosis membrane (2);

step S3: the blood enters the inner cavity and then contacts with the dialysate, meanwhile, the connecting plate (5) is driven to rotate through the rotating shaft (4), the blood disturbing component is driven to move through the rotation of the connecting plate (5), the blood in the inner cavity is disturbed under the action of the blood disturbing component, the contact area of the blood and the dialysate is increased, and the dialysis quality is improved;

step S4: the anti-blocking component is driven to move in the moving process of the blood disturbing component, and the filtering component is driven to vibrate through the movement of the anti-blocking component, so that a blocking object blocked in the filtering component is vibrated out, the filtering component is prevented from being blocked, and the filtering efficiency of the filtering component and the falling speed of blood are ensured;

step S5: the filtered and dialyzed blood is discharged through a blood outlet tube (30) and is conveyed by external equipment to be returned to the body of a patient, so that hemodialysis and filtration work is completed.
