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.
