Abstract
A two-piece ostomy appliance is disclosed having a faceplate component and a pouch component, the faceplate component including a flexible attachment ring having an annular outer flange portion and an inner collar portion for insertion into the side opening of the pouch component when the two are releasably joined together. The flushable pouch has a pair of side walls joined together along their outer margins with each wall comprising a primary layer of strong but water-soluble material and a protective inner layer of relatively weak but water-insoluble material. When the components are adhesively joined together, the protective collar of the faceplate attachment ring extends into the side opening of the pouch to shield the edge (or edges) of the water-soluble layer (or layers) from exposure to fluids and other matter discharged through the stoma-receiving opening of the faceplate into the pouch, thereby protecting the water-soluble layer(s) from premature disintegration.
