Abstract (en)
[origin: WO2011147425A1] Method and device for monitoring removal of hardly or easily diffusible uremic retention solutes during dialysis and for measuring concentration of said substances in a biological fluid, and more specifically in the spent dialysate, for estimation of dialysis dose on dialysis patients. Measurements are performed optically utilizing spectrum of the biological fluid and a concentration calculation algorithm containing the transforming function, including a unique set of optical spectral components at certain wavelengths, to determine the concentration of the substances in specimens in-vitro or flowing fluids on-line. Method and device determines the concentration of the substances in-vitro or on-line utilizing a measuring cuvette suitable for specified measurements. This enables monitoring quantitatively concentrations of substances in a biological fluid and calculation of the dialysis dose for hardly or easily diffusible uremic retention solutes, suitable for automatic and time-efficient way to review the dialysis quality delivered to the end stage renal disease patients.
