The cost for each home treatment is only 60 yuan (£6), which is 12 per cent of the hospital charge for dialysis,' Hu said.
two of his friends had died after building and using similar machines.
Hu's kidney disease means he has dangerously high levels of the minerals potassium and sodium in his blood. So he
created a dialysis solution that has similar levels of potassium and sodium to healthy human blood.
