People with renal failure and need blood purification through hemodialysis, in the near future will be able to obtain the freedom of movement. The U.S. company Xcorporeal Inc. has developed a portable "artificial kidney", held successful preliminary tests on humans, the journal Lancet.

Currently, hospital patients to connect to stationary vehicles "artificial kidney": as a result, they are riveted to bed at 4-12 hours 2-3 times a week. New apparatus for hemodialysis is portable - although fairly cumbersome - a device with a battery food, and up to 4-8 hours of continuous work.

The head of research Andrew Davenport (Andrew Davenport) and his colleagues from University College London (University College London) experienced portable "artificial kidney" at 8 patients, whose average age was 52 years. All participants in the study procedures required in regular haemodialysis.

In the tests came from two patients thrombosis, caused by insufficient protivosvertyvayuschey therapy; another patient was briefly disconnected from the apparatus because of a shift needles. Nonetheless, scientists have recognized tests successful, and the members unanimously agreed to recommend such treatment to other patients with renal insufficiency.

According to scientists, the procedure for cleaning blood in a portable "artificial kidney" occurs several slower than in a stationary apparatus. However, this does not represent the special problems, since the device can be easily be for a long time. Currently, the creators of portable "artificial kidney" trying to increase the duration of the apparatus, making 24 - of watch regime of its operation.

Nearly 1.3 million people worldwide suffer from chronic renal failure and need for regular dialysis. Only a few lucky ones, to await a suitable donor organ, conducting kidney transplant. Today's portable "artificial kidney" probably will be the first step towards a more convenient and portable miniature (and possibly ACG) hemodialysis machines, scientists believe.
