Figure 1 : (a) Photograph of the portable hemodialysis device prototype showing ports on either end of
the cartridge, which allow flow to be generated in countercurrent directions within the respective blood
and dialysate chambers. (b) MDCT image depicting the internal structure, which consists of adjacent
thin sheet-like chambers. In the superior half of the cartridge, a layer of filtration membranes
separates neighboring blood and dialysate chambers. In the inferior half of the cartridge, neighboring
blood and dialysate chambers are instead separated by a solid plate, which does not permit diffusion,
thus establishing an internal control.
