Abstract

Des moyens et un dispositif nouveaux permettent de quantifier de manière non invasive d'importants constituants du sang. On peut déterminer rapidement et facilement le taux d'hémoglobine totale, d'oxygène artériel, l'hématocrite et autres paramètres sans qu'il soit nécessaire de ponctionner la peau ou de procéder à de longues analyses en laboratoire. L'invention permet de mesurer en même temps des changements de volume et de masse de l'oxyhémoglobine, de l'hémoglobine totale ou de l'hémoglobine réduite. Les données obtenues par ces mesures sont utilisées pour quantifier les paramètres d'intérêt.
