Abstract

Dispositif permettant d'évacuer d'une seringue le liquide qu'elle contient, d'une façon régulière et suivant un débit souhaité, sans faire appel au courant électrique comme énergie. Il comporte en amont de la seringue un ressort permettant de pousser son piston et en aval, adapté au cône de seringue, un robinet constitué par un bouton gradué en millilitres/heure afin de déterminer le débit choisi et un obturateur différentiel régulant automatiquement son ouverture en fonction de la pression décroissante du liquide, au cours de l'injection, du fait de l'affaiblissement du ressort poussant le piston. Un réglage du ressort de poussée permet l'adaptation de n'importe quelle marque de seringue ; le réarmement du ressort est effectué à la main par l'opérateur; l'ensemble de poussée est coulissant afin de permettre un encombrement minimum lorsque l'appareil n'est pas utilisé. L'invention peut être utilisée principalement dans le domaine médical pour injecter un produit d'une façon prolongée, régulière et précise.
