要約(英語): For reducing the hemodialysis time of kidney disease patients, we are attempting to monitor hemodialysis quality in a real time based on dielectric constants of blood. Using a network analyzer with an open-ended coaxial-type dielectric probe, we measured complex relative permittivities ranging from 200 MHz to 6 GHz for blood of eighteen kidney disease patients before and after hemodialysis, and then derived from them admittance consisting of conductance G [S/m] and susceptance B [S/m] in order to make statistical correlation analyses between the G-B plots and blood biochemical components. As a result, we found that significant correlations are observed between the parameters of the linear approximations to the G-B plots at frequencies from 4 GHz to 6 GHz and blood urea nitrogen or creatinine before and after the hemodialysis. This finding suggests a possibility of real-time monitoring of the hemodialysis quality.
