Abstract
APARELHO DE DETERMINAÇÃO DA TAXA DE HEMOGLOBINA OU DE HEMATÓCRITO DE UM LÍQUIDO EM CIRCULAÇÃO. A presente invenção refere-se a um aparelho de determinação de uma taxa de hematócrito e/ou da taxa de hemoglobina de um líquido em circulação em uma porção tubular (2), compreendendo dois conjuntos emissor-receptor (10, 20), cada conjunto emissor-receptor (10, 20) compreendendo uma fon-te luminosa (11,21) e um sensor luminoso (12, 22) previstos para estarem dispostos de cada lado da porção tubular (2) no nível de uma zona de circulação do líquido para uma medição em transmissão; a fonte luminosa (11 21) de cada um dos dois conjuntos emissor-receptor (10, 20) estando configurada para emitir feixes luminosos de acordo com um comprimento de onda de emissão escolhido para corresponder a um ponto isobéstico da hemoglobina; cada conjunto emissor-receptor (10, 20) compreendendo ainda um sistema de colimação (13, 23) do feixe luminoso emitido da fonte luminosa (11, 21) na direção do sensor luminoso (12, 22) correspondente.
