Abstract

Système de seringue à commande électronique (14a) se raccordant à un cathéter de type ballon ou à un autre élément de type ballon et servant à contrôler, à afficher et à enregistrer automatiquement les données de gonflage quand on utilise le système de seringue pour gonfler le ballon du cathéter ou un autre élément de type ballon. Une seringue (16) comportant un cylindre (22) et un piston (24) fonctionne sélectivement pour augmenter la pression fluidique appliquée au cathéter ballon ou autre élément de type ballon au moyen de l'enfoncement du piston (24) dans le cylindre (22). On relâche la pression positive appliquée au cathéter ballon ou autre élément du même type en tirant le piston (24) vers l'arrière du cylindre (22). Un transducteur piézorésistif à semiconducteurs placé sur le cylindre (22) de la seringue (16) détecte la pression du fluide appliquée par la seringue. Le signal électrique émis par le transducteur est transmis dans un dispositif de contrôle (20a) dans lequel ledit signal est traité numériquement, afin de calculer et d'enregistrer les données électroniques représentant l'intensité de la pression fluidique appliquée et, également, afin de calculer la durée d'application de ladite pression. Les données électroniques représentant ladite information sont affichées et enregistrées automatiquement. Dans un mode de réalisation de l'invention, le dispositif de contrôle (20a) est également monté sur le cylindre de la seringue (22), afin de constituer un système de seringue de gonflage à commande numérique, totalement autonome et jetable.
