More precisely — on the unit for hemodialysis, assembled from discarded pieces in a small bathroom farm house in the eastern part of China. Three times a week a man named Hu Sonven comes to sit on the toilet for an artificial kidney, which he built 13 years ago, independently of kitchen utensils and old medical instruments.
In 1993, when Hu Sonven was a student, he developed kidney failure. For regular cleaning of blood had to resort to dialysis in hospital. During the six years of visiting the office with dialysis Chinese impoverished and decided not to pay more than the doctors.
Each routine dialysis blood drawn at home in the closet, a resident of the Chinese hinterland costs 60 yuan, which is 8 times cheaper than the same procedure in the clinic. Whenever Sonven Hu puts itself at risk — two of his colleagues were killed by misfortune after the construction and use of such home artificial kidney.
Dialysis fluid Hu prepares himself, using purified water, sodium and potassium, and sodium bicarbonate (baking soda). Being connected to the machine, craftsman introduces two tubes in catheters on hand veins. At one point, the blood is pumped into another — returns free of chemical waste.
Kidney disease in Chinese means that his blood potassium and sodium accumulate in life-threatening amounts. Therefore, the dialysis fluid Hu Sonven invented such that its ionic composition of sodium and potassium was similar to that of healthy human blood. When the blood and fluid run through the machine, the excess sodium and potassium pass through the membrane from the blood into the solution. Hu also have accumulated acid in the blood, so your solution adds Sonven soda.
Doctors periodically threaten all sorts of infections Homebrew — because the farmer is using non-sterile water. When the press did Hu Sonvenya famous and learned of his fate at the top, the government proposed to go to Hu hemodialysis in the hospital for the same money that he spends on cleaning blood at home. However, the patient is very awkward, because nearest hospital on dialysis is not around the corner and there's always a queue and crowd.
