Claims29
An ostomy appliance comprising
- a. a front panel and a rear panel, at least partly sealed to one another along their peripheries, said front and rear panels forming a pouch, the rear panel having a stomal opening for positioning around a stoma so that body waste excreted through the stoma is captured in said pouch;
- b. a filter for deodorization of odorous gas from the body waste, said filter located on the front panel and said filter comprising an opening for emitting said deodorized gas to the atmosphere;
- and
- c. a center panel between the front and rear panels which at least partly covers said filter, the center panel having a bottom edge that is positioned above the bottom edges of the front and rear panels and is attached to the front and rear panels along the periphery of the pouch;
- wherein the center panel comprises an area comprising one or more protrusions and an area that is substantially protrusion-free, wherein a portion of the center panel is exposed through the stomal opening, and wherein the portion of the center panel exposed through the stomal opening is within the area that is substantially protrusion-free.
