Abstract

Un infuseur comprend une pompe à perfusion (16) pour distribuer un liquide par l'entremise d'un conduit de perfusion (12) à partir de 8 sources distinctes de liquide vers un patient, un détecteur de bulles (17) permet de déceler la présence de bulles d'air dans le conduit de perfusion et des circuits de commande (22) reliés au détecteur de bulles permettent de déterminer si la dimension de la bulle d'air est inacceptable. Les circuits de commande sont configurés pour déterminer si la bulle d'air, une fois détectée, parcourt une distance pouvant indiquer qu'elle est de dimension inacceptable; une version de l'invention totalise les étapes d'une pompe péristaltique à perfusion linéaire, à cette fin.
