Haemodialysis During dialysis, the blood drained from a convenient artery is pumped into a dialysing unit after adding anticoagulant like heparin. The unit contains a coiled cell phone tube surrounded by a fluid (dialysing fluid) having the same composition as that of plasma except the nitrogenous wastes.
The porous cell phone membrane of the tube allows the passage of molecules based on concentration gradient. As nitrogenous wastes are absent in dialysing fluid these substances freely move out, there by clearing the blood. The cleared blood is pumped back to the body through a vein after adding antiheparin to it. This method is a boon for thousands of uremia patient all over the world
