Abstract

"SISTEMA PARA MONITORAR CONTINUAMENTE UMA CARACTERìSTICA DE UM FLUIDO BIOLóGICO EXTRAìDO DE UM ORGANISMO E PROCESSO PARA EXTRAIR UM FLUIDO BIOLóGICO DE UMA MEMBRANA BIOLóGICA DE UM ORGANISMO E MONITORAR CONTINUAMENTE UMA CARACTERìSTICA DO MESMO". Um sistema e processo para extrair um fluido biológico a partir de um organismo e monitorar suas características continuamente. O sistema compreende um dispositivo de interface de tecido 100, adequado para posicionamento sobre ou próximo à superfície da membrana biológica do organismo e uma unidade de monitoração e controle 200 acoplada ao dispositivo de interface de tecido 100. O dispositivo de interface de tecido 100 compreende um sensor 115 posicionado em um trajeto de escoamento do fluido para sensorear continuamente uma característica do fluido biológico quando ele escoa para fora de uma ou mais aberturas artificiais formadas na membrana biológica. O sensor 115 gera um sinal de sensor representativo dele. A unidade de monitoração e controle 200 lê eletricamente ou opticamente o sensor 115 para obter uma medição de uma característica, tal como concentração de um analito específico do fluido biológico em uma base contínua.
