How does the new artificial kidney developed in Japan work?

The research and development of artificial kidney is very fast, and all countries are studying artificial kidney which is closer to human physiological state. For example, in 1973, Japan manufactured an artificial kidney consisting of 10,000 thin hollow fibers with a diameter of 200 nanometers; 1985, the Japanese Medical Department in osaka city university developed a new type of artificial kidney, which can be driven only by the patient's own blood pressure. During the period of 1986, the liquid filtered by blood filter entered the intestine in Japan, and the reabsorption of glomerulus was replaced by live intestine. In the same year, Japan reported a portable artificial kidney that patients can carry with them, which is a dialysate regeneration artificial kidney with urea adsorbent. Combined with activated carbon and ion exchange resin, dialysis effect is good.

A small artificial kidney developed by Ablas, a famous Egyptian nephrologist, is the same size as a human kidney. Patients do not need hospitalization, wires and catheters, and can carry them with them without affecting their activities. Many patients are satisfied with the results after the experiment.

Now, scientists are strengthening the application and development of artificial kidney technology, strengthening the research of new artificial kidney materials, strengthening the purification of dialysis water, establishing a large artificial kidney center with computer data acquisition and automatic control, and designing and using new implantable artificial kidneys.
