Abstract
Méthode de mesure de débit d'un liquide, de sérum physiologique ou de sang, dans un vaisseau sanguin destiné à être utilisé comme greffe sur un patient nécessitant cette greffe, cette méthode consistant à faire passer une certaine quantité de ce fluide à travers ce vaisseau, dans des conditions régulées, puis à déterminer si ce vaisseau est approprié à être utilisé en tant que greffe. L'invention concerne également un système destiné à effectuer une telle mesure et qui comprend essentiellement une grande seringue raccordée à une pompe, laquelle fait circuler le fluide à travers le vaisseau sanguin destiné à la greffe, dans des conditions exactement déterminées, ainsi qu'un moyen destiné au calcul du débit et permettant de savoir si le vaisseau convient au patient désigné.
