Abstract

Cette invention concerne un système de mesure automatique de perfusion cutanée, lequel système comprend un instrument conçu pour analyser automatiquement les mesures de perfusion afin d'identifier des artefacts dus aux mouvements et des valeurs SPP (pression de perfusion cutanée), et un dispositif de pose de capteur. L'instrument est conçu pour ignorer les artefacts dus aux mouvements. Les mesures de perfusion sont désignées en tant que valeurs SPP si plusieurs critères sont satisfaits. Les critères de valeurs SPP se rapportent à des facteurs parmi lesquels la pression au poignet, la perfusion, les pourcentages de modification de perfusion par rapport aux mesures de perfusion préalables et ultérieures. Le dispositif de pose de capteur permet de garantir l'obtention de données fiables lorsque plusieurs mesures sont souhaitées.
