Title
(EN) AN INFUSION DEVICE FOR MEDICAL USE.
(FR) DISPOSITIF DE PERFUSION A USAGE MEDICAL
Abstract
(EN)
A description is given of an infusion device for medical use, comprising a container (4) designed to hold a specified quantity of a liquid to be infused into a patient, a weighing device (7) associated for operation with the container to measure the weight of the container and emit a corresponding control signal, a transport line (2) connected to the container, a pump (9) and a control unit (8) associated with the weighing device and with the pump. The control unit is capable of detecting the end of infusion condition and of commanding the pump to stop the transport of fluid. A separator (10) for continuously separating fluid into a gaseous portion and a liquid portion operates in the infusion line downstream of the pump and prevents the infusion of gas during the stopping transient of the pump at the end of infusion.
(FR)
L'invention a trait à un dispositif de perfusion à usage médical, qui comprend un récipient (4) conçu pour contenir une quantité donnée d'un liquide devant être administré à un patient par perfusion, un dispositif de pesée (7) qui, associé de manière fonctionnelle au récipient, est destiné à mesurer le poids du récipient et à émettre un signal de commande correspondant, une ligne d'acheminement (2) reliée au récipient, une pompe (9), et une unité de commande (8) associée au dispositif de pesée et à la pompe. L'unité de commande peut détecter la fin d'un état de perfusion, et commander la pompe pour que celle-ci interrompe l'acheminement du fluide. Un séparateur (10), conçu pour séparer de manière continue le fluide en une partie gazeuse et en une partie liquide, est placé dans la ligne de perfusion en aval de la pompe, et empêche la perfusion de gaz lors de l'état transitoire d'interruption de la pompe à la fin de la perfusion.
