Dialysate-free-artificial-kidney (DIFAK)

Abstract

We have been working on the development of portable and handy artificial kidney which does not need a special room to install it. For this purpose, we tried to reduce the dialysate volume necessary for a dialysis by adding adsorbents into dialysate. Theoretically, substances with more than middle molecular weights can be removed by recirculating 30L of dialysate and adsorbents are necessary for the improvement of dialysis efficiency. We have examined some adsorbents suitable for the purpose and studied the bacterial growth expected during the recirculation of dialysate.
It can be concluded that our present system of 30L dialysate with 500g of activated charcoal and 200g of alumina is capable of short time dialysis without causing any disequilibrium syndrome.
