Abstract
Valve régulatrice de pression pour shunt chirurgical, et procédé de vénfication de l'étanchéité de son obturateur. Une cloison 14 divise le corps Il de la valve en deux compartiments d'entrée 15 et de sortie 16 qui communiquent par un trou rond 17 percé dans la cloison. Un ressort 20, 21 en epingle à cheveux, dont une branche entre tangentiellement en contact avec un clapet sphérique 19, tend à maintenir ce dernier en contact étanche avec le bord du trou 17 dans le compartiment 16. La pression ainsi exercée est déterminée de façon à réduire l'hystérérésis du clapet à l'ouverture et à empêcher son colmatage par des impuretés. La vérification de l'étanchéité se fait en illuminant le trou bouché par le clapet et en s'assurant que les rayons lumineux ne le traversent pas. Application aux appareillages chirurgicaux.
