Abstract
On fait descendre de façon contrôlée deux sondes tubulaires 6a, 6b d'une hauteur donnée dans un récipient 1 contenant, à l'état séparé en deux couches superposées, les constituants plasmatique 2 et globulaire 3 d'un échantillon de sang. Des électrodes 4 aux extrémités inférieures des sondes détectent les surfaces des couches et délivrent des signaux à une unité de traitement 5. Des quantités prédéterminées des deux constituants 2, 3 sont aspirées hors du récipient 1, à travers l'une ou l'autre sonde, et sont injectées dans deux récipients d'échantillonnage 7 séparés. Des unités arithmétiques 10 et de détermination 11 calculent l'hématocrite d'après les hauteurs c, d auxquelles sont délivrées les signaux de détection, vérifient le résultat par comparaison avec des valeurs normales pour l'homme et la femme et déclenchent un marquage des récipients 1, 7 en cas d'anormalité.
