Abstract

um sistema para detectar uma posição de uma cânula pode incluir uma cânula, que pode incluir uma extremidade distal e um lúmen interno. também, o sistema pode incluir uma fibra ótica, que pode estar disposta dentro do lúmen interno da cânula e pode incluir uma primeira extremidade, uma segunda extremidade, e uma porção em forma de u dispostas entre a primeira extremidade e a segunda extremidade. a porção em forma de u pode ser pelo menos próxima a extremidade distal. além disso, o sistema pode incluir um emissor de luz, que pode ser acoplado à primeira extremidade da fibra ótica, e um receptor de luz, que pode ser acoplado à segunda extremidade da fibra ótica. além disso, o sistema pode incluir um processador eletrônico. o processador eletrônico pode ser acoplado ao receptor de luz e configurado para detectar uma diminuição em uma intensidade de luz recebida no receptor de luz.
