Abstract

"OXìMETRO DIGITAL E MéTODO DE CáLCULO DE NìVEIS DE OXIGENAçãO". A presente invenção revela um oxímetro para medir não invasivamente a saturação de oxigênio no sangue com aumentada velocidade e acurácia. O oxímetro inclui um número de características que aumentam a funcionalidade do dispositivo incluindo: um controlador dinâmico de faixa ( 62 ) para monitorar uma faixa de entradas desde sinais de nível baixo encontrados em fetos e outras aplicações até sinais de nível normal ou alto; dispositivos emissores de luz ( 70, 80, 100 ) de diferentes comprimentos de onda para filtrar ruído e fornecer funções adicionais de monitoramento médico; e um método aperfeiçoado para calcular os níveis de oxigenação sem haver necessidade de realizar medidas de pico e vale. O dispositivo inclui uma unidade de sensor ( 20 ) que pode ser conectada a um paciente e a um oxímetro que determina a saturação de oxigênio no sangue baseado nos sinais recebidos a partir do sensor ( 20 ). O sensor ( 20 ) pode incluir dispositivos emissores de luz ( 70, 80, 100 ) em três ou mais comprimentos de onda para fornecer funções adicionais. Na presente invenção, o sinal detectado é imediatamente convertido em um valor digital.
