The function of the kidneys is to clean out any impurities and waste products from the blood. If our kidneys do not work properly we might die. But people suffering from kidney disease can receive dialysis treatment, a medical technology for purifying blood. Doctor Nils Alwall in Lund designed a dialysis machine in the mid-1940s which was the first in the world to be used in hospitals. In Sweden nearly 3,000 people are treated with dialysis every year and throughout the entire world about a million people need dialysis to survive.

Blood is pumped into the dialysis machine which has a membrane, a filter with microscopic pores.
On the other side of the membrane there is dialysis fluid. The fluid attracts waste products from the blood. The purified blood is then pumped back into the patient.
