Title (EN) PERISTALTIC INFUSION PUMP HAVING MECHANISM FOR RESHAPING THE FLEXIBLE TUBE
(FR) ACTIONNEURS DE POMPE A INFUSION, SYSTEME ET PROCEDE POUR REGULER LA VITESSE D'ECOULEMENT D'UN FLUIDE MEDICAL
Abstract:
(EN) An infusion pump includes an actuator having an output shaft; a pump actuator comprising a plurality of members (30a, 30b, 30c, 30d) in hinged communication with each other so as to form a parallelogram construction, the plurality of members being hinged to the output shaft, and having a length 1 actuator moved by the output shaft and in contact with tubing, such that the pump actuator at an output shaft actuated distance x creates flat contact areas with the tubing, and wherein remaining non-contact areas of the tubing are at least substantially circular in shape; and a logic implementer configured to use at least two relationships to solve for a same number of variables to calculate a cross-sectional area of the tubing at an output shaft actuated distance x.
(FR) L'invention concerne une pompe à infusion ayant un arbre de sortie; un actionneur de pompe dont la longueur lactuator est déplacée par l'arbre de sortie et est en contact avec un tubage, de sorte que l'actionneur de pompe à une distance x d'un arbre de sortie actionné crée des zones de contact plates avec le tubage, les zones de tubage restantes sans contact étant au moins sensiblement de forme circulaire; et un outil logique conçu pour utiliser au moins deux groupes pour résoudre un même nombre de variables pour calculer une zone transversale du tubage à une distance x d'un arbre actionné.
