Dialyzer For Hemodialysis machine
A hemodialyzer is a key device used in hemodialysis treatment, whose main role is to purify the blood by removing waste and excess water from the blood through an artificial semi-permeable membrane. The working principle of the hemodialyzer is based on the action of solute diffusion, osmotic pressure difference and transmembrane pressure. The dialyzer consists of 8,000-12,000 hollow fibers with an inner diameter of about 200 microns.
