Abstract
A concept of no-dialysate micro hemodialysis system is presented and water permeability of the dialysis membrane is discussed in this paper. No-dialysate micro hemodialysis system makes it possible to miniaturize the hemodialysis system, which is mandatory for our ultimate goal of implantable dialysis systems. Water permeability of the dialysis membrane is a crucial parameter to determine the system performance. We highlighted nano-porous poly-ether-sulfone (PES) membrane and developed water-permeable dialysis membrane. We successfully conducted proof of concept experiments of no-dialysis micro hemodialysis system and experimentally found that the thickness of nano porous structure affected water permeability.
