Abstract

Patente de Invenção: <B>"PROCESSO PARA A DETERMINAçãO DA DIALISANCE E DISPOSITIVO PARA A EXECUçãO DO PROCESSO"<D>. De acordo com o método segundo a presente invenção para a determinação da dialisance de uma máquina de dialise durante um tratamento extracorporal de sangue, a concentração de uma determinada substância no líquido de diálise é alterada no canal do líquido de diálise, a montante da máquina de diálise. A concentração de tal substância é alterada na base de um valor inicial predeterminado e depois, reajustada para o valor inicial. A concentração da substância no líquido de diálise é medida com um dispositivo de medição (17, 18), disposto a montante ou a jusante da máquina de diálise. O quociente do integral da diferença entre a concentração do líquido de diálise de saída cdo(t) e o valor inicial predeterminado cdo1 sobre o tempo e o integral da diferença entre a concentração do líquido de diálise de entrada cdi(t) e o valor inicial cdi1 sobre o tempo é calculado numa unidade de avaliação e aritmética (23) e a dialisance depois é determinada na base do quociente calculado e da taxa de fluxo Qd do líquido de diálise no canal do líquido de diálise.Invention Patent: <B> "PROCESS FOR DETERMINING THE DIALISANCE AND DEVICE FOR THE EXECUTION OF THE PROCESS" <D>. According to the method according to the present invention for determining the dialysis of a dialysis machine during an extracorporeal treatment of blood, the concentration of a certain substance in the dialysis fluid is changed in the dialysis fluid channel, upstream of the dialysis machine. dialysis. The concentration of such a substance is changed on the basis of a predetermined initial value and then readjusted to the initial value. The concentration of the substance in the dialysis liquid is measured with a measuring device (17, 18), arranged upstream or downstream of the dialysis machine. The quotient of the integral of the difference between the concentration of the dialysis liquid cdo (t) and the predetermined initial value cdo1 over time and the integral of the difference between the concentration of the dialysis liquid cdi (t) and the initial value cdi1 over time is calculated in an evaluation and arithmetic unit (23) and the dialisance is then determined on the basis of the calculated quotient and flow rate Qd of the dialysis liquid in the dialysis liquid channel.
