Dialüüsimembraanidel

Dialüüsimembraanidel is the plural form of dialüüsimembraan, meaning dialysis membrane in Estonian. Dialysis membranes are semi-permeable barriers used in medical procedures, most notably hemodialysis and peritoneal dialysis, to remove waste products and excess fluid from the blood or peritoneal cavity. These membranes are typically made from synthetic polymers like polysulfone, polyethersulfone, or cellulose derivatives. They possess pores of specific sizes that allow small molecules such as urea, creatinine, and electrolytes to pass through while retaining larger molecules like proteins and blood cells. The process relies on diffusion and convection, where solutes move from an area of high concentration to low concentration, and fluid is dragged across the membrane by a pressure gradient. The efficiency of dialysis is largely determined by the membrane's surface area, pore size distribution, and permeability. Different types of membranes are chosen based on patient needs and the desired level of solute and fluid removal. The development of biocompatible and highly efficient dialysis membranes has been crucial in improving the treatment outcomes for patients with kidney failure.
