Abstract

L'invention concerne le domaine du contrôle du degré d'hydratation du corps humain basé sur la mesure du temps nécessaire au sang pour remplir à nouveau un vaisseau sanguin occlus, notamment en mesurant le temps de remplissage veineux (TRV) et/ou le temps de remplissage capillaire (TRC). L'invention propose un procédé I dans lequel le tissu comprenant le vaisseau sanguin est exposé à un rayonnement lumineux à polarisation linéaire à au moins une longueur d'onde prédéfinie ; la partie de la lumière réfléchie qui est polarisée perpendiculairement au rayonnement lumineux appliqué est recueillie sous la forme d'une image ; le vaisseau sanguin est occlus afin d'empêcher le sang d'y circuler ; l'occlusion du vaisseau sanguin est supprimée afin de permettre au sang de remplir à nouveau le vaisseau sanguin ; l'image est analysée afin de déterminer l'écoulement des cellules sanguines ; et le temps nécessaire pour revenir à un débit prédéfini des cellules sanguines après la suppression de l'occlusion est mesuré. Ce procédé permet de contrôler aisément, de manière spécifique et précise, le degré d'hydratation du corps humain.
