A medical device such as a controlled discharge ostomy appliance comprises a fluid filled seal for sealing around a body orifice (stoma). The fluid filled seal comprises a fluid chamber including a fluid impermeable membrane that forms a movable wall of the fluid chamber, one or more ports communicating with the chamber; and resilient foam disposed within the fluid chamber. The foam tends to expand the chamber to seal against the body. The port controls the inlet and exhaust of fluid from the chamber, in response to movement of the body away from, or towards, the seal.

La présente concerne un dispositif médical tel qu'un appareil stomique à décharge contrôlée comportant un joint rempli de fluide pour constituer un joint autour d'un orifice corporel (stomie). Le joint rempli de fluide comporte une enceinte de fluide comprenant une membrane imperméable au fluide qui forme une paroi mobile de l'enceinte de fluide, un ou des orifices en communication avec l'enceinte ; et une mousse élastique disposée dans l'enceinte de fluide. La mousse tend à dilater l'enceinte pour être scellé contre le corps. L'orifice contrôle l'entrée et la sortie de fluide depuis l'enceinte, en réaction à un mouvement du corps en éloignement du joint ou vers celui-ci.
