Fabrication and experiment of the hemodialysis unit device

This study presents the hemodialysis unit device that can effectively separate waste urea from the human blood. This device is composed of donor and acceptor channels separated by a membrane. The mixture of albumin, urea, and glucose used to replace simple human blood is fractionated by different particle sizes and diffusion distances across the cross section of the channels. In this study, FEM simulation and experimental study are used to verify the proposed device and show good agreement. The experimental results illustrate the clearance of urea with respect to the flow rate, the length of the channel, and the depth of the channel. This work demonstrates around 50% of the urea clearance efficiency can be obtained.
