CA 2223100
A method and apparatus is disclosed for determining a erythrocyte sedimentation rate and hematrocrit simultaneously with the centrifugation of whole blood. A centrifuge separates the whole blood into its erythrocytes and its fluid portion. A video camera measures the levels of whole blood, erythrocytes, and the fluid portion of the blood and records the time of the formation of an interface between the erythrocytes and fluid portion. A monitor displays the results of the recording. Also disclosed are the method steps performed.
L'invention concerne un procédé et un dispositif servant à déterminer la vitesse de sédimentation des érythrocytes, ainsi que l'hématocrite simultanément à la centrifugation du sang entier. Une centrifugeuse sépare le sang entier en érythrocytes et en partie liquide. Une caméra vidéo mesure les niveaux du sang entier, des érythrocytes et de la partie liquide du sang et enregistre le temps de formation d'une face de contact entre les érythrocytes et la partie liquide Un moniteur affiche les résultats de l'enregistrement. L'invention concerne également la réalisation des étapes du procédé.
