A flexible membrane is situated within a rigid or semi-rigid cap. The edge of the cap wall is adhesively fined to the tissue surrounding the stoma. The interior of the cap is pressurized to press the membrane to seal the stoma against the discharge of solid and semi-solid waste. Gas escapes through a vent with a filter element. pressurized by an external pump or an integral pump member situated on top of the cap. A relief valve prevents over pressurization. A collection pouch can be provided as part of a device. The device can be removably mounted on a standard two-piece faceplate.

Une membrane flexible est située à l'intérieur d'un capuchon rigide ou semi-rigide. La bordure de la paroi du capuchon est fixée par adhésion au tissu entourant la stomie. L'intérieur du capuchon est pressurisé afin de comprimer la membrane contre la stomie, ce qui scelle cette dernière et empêche l'évacuation des déchets solides et semi-solides. Les gaz s'échappent par un évent muni d'un élément filtrant pressurisé par une pompe externe ou une pompe intégrale située sur le dessus du capuchon. Une soupape de surpression empêche la surpressurisation. Une poche destinée à la collecte peut être fournie avec le dispositif. Le dispositif peut être retiré et installé sur une plaque de recouvrement standard à deux pièces.
