✔Artificial kidney/ dialyser , is a machine that is used to filter the blood

of a person whose kidneys are damaged. This process is called Hemodialysis.

✔ In process blood is taken out from the main artery, mixed with an anticoagulant, such as heparin , and then pumped into the apparatus called Dialyser.

✔ In this apparatus blood flows through channels, or tubes made of Cellophane.

✔The membrane is impermeable to macromolecules, such as Plasma proteins, but permeable to small solutes such as urea, uric acid, creatinine and mineral ions.

✔ The membrane separates the blood flowing inside the tube and the dialyzing fluid (dialysate) , which has the same composition as that of plasma except the nitrogenous wastes.

✔ The cellophane membrane allows passage of molecules based on concentration gradient.

✔ As nitrogenous wastes are absent in the dialyzing fluid,these substances from the blood freely move out ,there by clearing the blood of its wastes. This process is called Dialysis.

✔The cleared blood is pumped back into the body through a vein after adding anti heparin to it.

✔Each dialysis session lasts 2 to 6 hours.

✔ This method is boon for thousands of Uremic /kidney failure patients all over the world.
