Background

The dialyzer is composed of hollow fibers made of chemical materials, numerous small holes are distributed on each hollow fiber, blood flows through the inside of the hollow fibers during dialysis, dialysate flows through the outside of idle fibers in a reverse direction, solutes and water in small molecules in the blood/dialysate are exchanged through the small holes on the hollow fibers, the final result of the exchange is that toxins, electrolytes and redundant water in the blood enter the dialysate to be removed, and bicarbonate radicals and electrolytes in the dialysate enter the blood, so that the aims of removing toxins and water, maintaining acid-base balance and stabilizing internal environment are fulfilled. The total area of the entire hollow fiber, the exchange area, determines the capacity of small molecule species to pass through, while the size of the membrane pore size determines the capacity of medium and large molecules to pass through. High-flux dialysis is hemodialysis performed by using a dialyzer with high permeability to solutes, moisture and other substances, the ultrafiltration coefficient of the high-flux hemodialysis is high, and the removal of large and medium molecular toxins is good, but the currently used dialysis membrane has large aperture and high ultrafiltration coefficient, and the high-flux dialysis also has some disadvantages in practical use, such as excessively high dialysis speed, which easily causes the physical function of a patient to be reduced, causes discomfort of the patient, and even affects the safety of the patient.
