Dialysointikalvo

Dialysointikalvo, commonly referred to as a dialysis membrane, is a semipermeable barrier essential for the process of dialysis. This membrane allows for the selective passage of molecules based on their size and concentration gradient. During hemodialysis, the dialysointikalvo acts as the interface between the patient's blood and the dialysate fluid. Small waste products such as urea, creatinine, and excess electrolytes from the blood diffuse across the membrane into the dialysate, which contains a carefully balanced concentration of these substances to prevent their removal from the blood. Conversely, essential components like red blood cells and large proteins are too large to pass through the pores of the membrane and remain in the blood.

The material composition and pore size of the dialysointikalvo are critical factors determining its efficiency and biocompatibility. Modern dialysis membranes are typically made from synthetic polymers such as polysulfone, polyethersulfone, or cellulose derivatives. These synthetic membranes offer consistent performance and reduced risk of allergic reactions compared to earlier artificial kidney membranes. The structure of the membrane, often a hollow fiber configuration, maximizes the surface area available for diffusion and ultrafiltration, thereby enhancing the effectiveness of waste removal and fluid balance management. The integrity of the dialysointikalvo is paramount to prevent blood leakage and ensure safe operation of the dialysis procedure.
