!!Chinese man_dialysis machine_self made
Chinese man keeps himself alive for 13 years with HOMEMADE dialysis machine (bet you'll never complain about the NHS again!)

· Hu Songwen built his machine after he could ** longer afford hospital bills
· He said two of his friends had died after building and using similar machines
· Offered Government medical aid after story went national, but says nearest hospital is too far away and too crowded

Three times a week, Hu Songwen sits on a small toilet in his home in a rural east China town and fires up his homemade dialysis machine.
Hu, who suffers from kidney disease, made it from kitchen utensils and old medical instruments after he could ** long afford hospital fees.
He was a college student when he was diag**sed in 1993 with kidney disease, which means waste products can**t be ******* from his blood.
He underwent dialysis treatment in hospital but ran out of savings after six years. His solution was to create his own machine to slash his costs.

Hu Songwen uses his dialysis machine three times a week. He says it has kept him alive for 13 years
'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 **t deterred despite the fact two of his friends had died after building and using similar machines.
The machine works like an external kidney. It is made up of two compartments that are connected by a membrane (a film-like structure that allows only some particles to pass through it).
Blood is pumped through one half of the machine, while the dialysis fluid is pumped through the other half.
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.
This spontaneous movement of particles from a high to a low concentration through a membrane is k**wn as diffusion.
The 'clean' blood is then pumped back into his body.

Hu's condition also means he has high levels of acid in his bodily fluids.losha - www.losha.net
This can be dealt with by putting bicarbonate back into his body. In this case, particles from the fluid pass the other way through the membrane from the fluid into the blood, ready to go back into his body.
Doctors warn that Hu runs the risk of serious infection as well as long-term complications by **t using sterile water to make the fluid.
But Hu, who lives with his 81-year-old mother in Qutang township of Jiangsu Province, says he has limited options.
Hu was offered medical aid by the Government when his story sparked national interest thanks to report in the Southern Weekly.
The funds would would bring the cost of hospital treatment down to the same level as his home treatment. However, Hu said he was reluctant to switch as the nearest hospital is far away and very crowded.
Although a Communist country, China does **t have a cradle-to-grave free-at-the-point of use healthcare system.
Instead around half of the population buy basic medical insurance which covers for half the costs of their healthcare. The remainder is paid either by patients or their health insurer.
However, this leaves the poorest in China struggling to meet medical bills for serious conditions.
