The dialyzer is mainly composed of a support structure and a dialyzer membrane, in which the dialyzer membrane is a semipermeable membrane that allows molecules smaller than the membrane pore size to pass through.
This structure allows blood and dialysate to exchange substances during the dialysis process, mainly through diffusion, convection and ultrafiltration. During hemodialysis, blood flows through the inside of the hollow fiber, while the dialysate flows outside the fiber, exchanging substances through the semipermeable membrane to remove waste and excess water from the blood. This structure not only simulates the natural filtration function of the kidney, but also effectively helps treat acute and chronic renal failure and toxic diseases, etc.
