Chinese man keeps himself alive for 13 years with HOMEMADE dialysis machine

'The cost for each home treatment is only 60 yuan (£6), which is 12 per cent of the hospital charge for dialysis,' Hu said.

He said he was not deterred despite the fact two of his friends had died after building and using similar machines.

Hu makes the dialysis fluid by mixing potassium chloride, sodium chloride and sodium hydrogen carbonate (bicarbonate) into purified water.

For the treatment, he inserts two tubes into his arm, which are connected to his dialysis machine. The blood is pumped out of his arm through one of the tubes, is filtered and then returned to his body via the other tube.

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.

When the blood and dialysis fluid go through the machine, these excess minerals are encouraged to go from his blood and through the membrane to the fluid. This removes the waste products from his blood - and the fluid is later thrown away.
