Abstract
La présente invention a pour objet un procédé et un appareil de commande servant à déterminer des paramètres du sang. Elle est caractérisée en ce qu'on fait passer la suspension dans un capillaire, en ce qu'on produit un signal caractérisant le nombre et la dimension des particules passant dans le capillaire, en ce qu'on mémorise numériquement l'information se rapportant au nombre desdites panicules, auquel cas les impulsions des signaux caractérisant le nombre et la dimension des particules sont sélectionnées en fonction de leur amplitude et de leur durée et les valeurs des amplitudes des impulsions - qui correspondent aux conditions de sélection - sont déterminées numériquement et additionnées; ensuite, on définit un compartiment de mémorisation par la valeur numérique de l'amplitude en vue de déterminer la répartition des particules suivant leur volume et, en conséquence, on détermine la valeur du volume moyen des cellules et leur courbe de répartition. Elle se rapporte à des installations médicales.
