Counter-current flow in artificial kidneys

ABSTRACT

The he parameters controlling the design and function of artificial 1 kidney systems, namely surface area of the transfer medium, [membrane], its permeability as well as operating conditions such as the rate of flow of both the blood and dialysate were correlated, The obtained correlation provides a means For calculating the artificial kidney performance [dialysance] in terms of blood flow rat blood to dialysate flow rate ratio, membrane surface area and membrane permeability D= Q B[1- [1-k] / [e[1-k] PA / Q[B-k]] < 1 Considering the equation commonly used for calculating membrane permeability i.e. Renkin formula it is worth noting that it can only be applied for specific cases where blood to dialysate flow rates are extremely low and it may be considered as a specific case of the predicted equation
