Title
(EN) OCCLUSION DETECTION SYSTEM FOR AN INFUSION PUMP
(FR) SYSTEME DE DETECTION D'OCCLUSION DESTINE A UNE POMPE A TRANSFUSION
Abstract
(EN)
The invention relates to a method and system for monitoring pressure conditions in the fluid pressure upstream and downstream of an intravenous fluid administration system and to detect upstream and/or downstream occlusions. In addition, the invention incorporates a method for detecting pressure conditions at an upstream or downstream detector across the wall of the tubing to identify upstream or downstream occlusions, respectively. The present invention also relates to a process for determining the fluid pressure in a fluid tube across the tube wall where the normal tube force changes over time, and more particularly, using a normalization process to eliminate changes in the tubing resilience.
(FR)
La présente invention concerne un procédé et un système de surveillance des conditions de pression d'un fluide en amont et en aval d'un système d'administration intraveineuse de fluide, et permettant de détecter des occlusions en amont et/ou en aval. L'invention concerne en outre un procédé de détection des conditions de pression au niveau d'un détecteur amont ou aval au travers de la paroi d'un tubage, repérant si l'occlusion s'est produite en amont ou en aval. L'invention concerne également un procédé de détermination de la pression de fluide dans un tube à fluide au travers de la paroi du tube dans le cas où les forces s'exerçant normalement contre le tube se modifient avec le temps, ce procédé mettant en ÷uvre en l'occurrence une procédure de normalisation destinée à éliminer les modifications de résilience du tubage.
