FIELD: medicine.
SUBSTANCE: group of inventions relates to medical equipment. Device contains dialysis unit, divided into first and second chambers by semipermeable membrane. First chamber is located in the way of dialysis solution, second is made with possibility of connection to blood circulation system. In addition, dialysis unit includes line of fresh dialysis solution supply, discharge line for spent dialysis solution and measuring device, located in discharge line for assessment of absorption by spent dialysis solution. Measuring device contains radiation source for emission of monochromatic electromagnetic radiation, and detecting system for determination of electromagnetic radiation intensity. Provided are means for compensation of changes which emerge in intensity of electromagnetic radiation of radiation source and/or detector system sensitivity. Temperature regulator is provided as means for regulation of radiation source temperature to preliminarily specified working temperature T1 and/or temperature of detector system to preliminarily specified working temperature T2. Disclosed is method of compensating changes in intensity of electromagnetic radiation source and/or detector system sensitivity.
EFFECT: reliable and accurate determination of substance concentration in discharge line, which serves as indicator of renal replacement therapy.
