CA 2423447

An ostomy appliance is described in the form of a controlled discharge device for controlling discharge from the stoma and/or an ostomy pouch for collecting discharged waste. The appliance may include one or more of: an elastomeric stoma seal for providing a seal around or directly against the stoma; a stoma occluder for occluding the stoma without passing internally into the stoma; a peristomal foam wall; a confinement seat for confining at least solid excreta to a confinement region adjacent to the stoma; a stowable collector bag; and interchangeable controlled discharge devices and ostomy pouches. The foam wall may provide a barrier to stool; but allow escape of flatus. The foam wall and/or the stoma occluder and/or the confinement seal may apply a force in a direction to increase the sealing force on the stoma seal.

Cette invention décrit un appareillage de stomie se présentant sous la forme d'un dispositif permettant de contrôler l'évacuation des selles sortant de la stomie et/ou une poche collectrice. L'appareillage peut comprendre un ou plusieurs des éléments suivants : un joint en élastomère assurant une étanchéité autour de la stomie ou directement à son endroit, un dispositif d'occlusion fermant la stomie sans la traverser, une paroi péristomiale en mousse, un joint assurant le confinement d'au moins l'excréta solide à une zone de confinement adjacente à la stomie, un sac collecteur repliable, des dispositifs interchangeables permettant de contrôler l'évacuation des selles ainsi que des poches. La paroi en mousse peut agir comme une barrière arrêtant les selles, mais permet l'évacuation des gaz intestinaux. La paroi en mousse et/ou le dispositif d'occlusion et/ou le joint assurant le confinement peuvent appliquer une force dans une direction donnée pour augmenter la force du joint d'étanchéité fermant la stomie.
