Abstract

"REGULADOR, DE MáSCARA DE DILUIçãO E DEMANDA E MéTODO DE REGULAGEM DE OXIGêNIO ADICIONAL NO REGULADOR, DE MáSCARA". Um regulador de máscara de demanda e diluição compreendendo um circuito de alimentação de oxigênio e um circuito de diluição para suprimento de ar. O circuito de alimentação de oxigênio e o circuito de diluição estão conectados a uma câmara de mistura (35) . No circuito de diluição, a taxa de escoamento de ar de inalação inalado é medida através de um duto capilar (43) conectado a uma construção Venturi (41). Um método de regulagem de taxa de escoamento de oxigênio adicional utiliza dados de taxa de escoamento medidos através do duto capilar .(43) para o controle da taxa de escoamento de oxigênio a ser suprida à câmara de mistura (35).
