Abstract

PROCESSO, EQUIPAMENTO PORTáTIL E DISPOSITIVO PARA A DETERMINAçãO FOTOMéTRICA IN VITRO DA CONCENTRAçãO DE HEMOGLOBINA EM UMA AMOSTRA DE SANGUE DILUìDA EM UMA Só ETAPA. A presente invenção se refere a um processo, equipamento portátil e dispositivo para a determinação fotométrica in vitro da concentração de hemoglobina em sangue diluído. A presente invenção viabiliza sua utilização em programas de prospecção de anemias a campo. A presente invenção compreende uma fonte de luz (1) com comprimento de onda entre 500 e 550 nm, um suporte de amostras (3) cilíndrico, com diâmetro entre 8 e 20 mm, um foto-sensor (2) para realizar a fotometria da amostra e um microprocessador para acionamento automático da fonte de luz, aquisição do sinal obtido pelo foto-sensor (2), realização dos cálculos da concentração de hemoglobina e exibição dos resultados em um display de cristal líquido. O dispositivo compreende um frasco cilíndrico lacrado que é concomitantemente utilizado como embalagem para o reagente e como componente óptico do processo, permitindo a leitura fotométrica através de suas paredes.
