Abstract

L'invention concerne un dispositif de transfusion facilement utilisable par un utilisateur, présentant notamment une interface utilisateur pouvant déclencher une alarme nécessaire à l'utilisateur (personne suivant des soins médicaux) lors de troubles apparaissant lorsqu'une quantité de transfusion et un débit de transfusion sont définis avant la transfusion. Le dispositif de transfusion comprend une partie réglage permettant de régler la quantité de transfusion et le débit de transfusion, ainsi qu'une partie affichage permettant d'afficher la quantité de transfusion et le débit de transfusion et est caractérisé en ce que lorsqu'un débit de transfusion (mL/h) est entré au niveau de la partie réglage, le débit augmente ou diminue unité par unité en synchronisme avec le son du vibreur chaque fois qu'un clavier numérique 100 est pressé. Ainsi, le dispositif de transfusion comprend la partie réglage permettant de régler la quantité de transfusion et le débit de transfusion et une partie affichage permettant d'afficher la quantité de transfusion et le débit de transfusion, et est caractérisé en ce que les seuils des longueurs détectées de bulles d'air sont classées en deux groupes spécifiés de sorte que l'un ou l'autre puisse être sélectionné.
