Abstract
Clapet de retenue sensible à de très faibles différences de pression. Il comprend un corps creux ayant un orifice d'admission et un orifice de sortie reliés à une partie intermédiaire agrandie. Un diaphragme souple, fixé hermétiquement par sa périphérie à la partie agrandie, comprend un élément dont la partie externe est ajourée et la partie centrale est pleine. L'élément plein est espacé d'un siège de sorte que lorsqu'un liquide s'écoule de l'orifice d'admission vers l'orifice de sortie, il passe librement autour de la partie pleine par la partie ajourée En cas d'augmentation de la pression s'exerçant contre le diaphragme, sa partie pleine s'applique hermétiquement contre le siège de façon à interrompre l'écoulement du liquide. Application à l'administmtion successive de solutions parentérales primaire et secondaire à un patient par un conduit commun.
