Ostomy appliance with extrudable gasket

An ostomy appliance comprising a collection pouch and faceplate assembly;

• said faceplate assembly including a flexible patch having a stoma-receiving opening, a first layer of skinfriendly hydrocolloid-containing adhesive material along one side of said patch about said opening for securing said faceplate assembly to peristomal skin surfaces, and a second layer of relatively soft, easily-deformable and extrudable, adhesive sealant material of a composition that is resistant to being dissolved or disintegrated by stomal fluids and that immediately surrounds said opening;
• said second layer being displacable inwardly and axially into said opening for forming a stoma-engaging annular gasket to prevent stomal fluids from contacting said first adhesive layer;
• said first and second layers being in direct planar contact with each other;
• said faceplate assembly being contoured and having a relatively thick annular inner portion of adhesive material and a relatively thin annular outer flange portion of adhesive material;
• said relatively thick annular inner portion and said annular outer flange portion being composed of both of said first adhesive layer and said second adhesive layer.

• said appliance being a two-piece appliance with said pouch and faceplate being detachably connected together;
• said second adhesive layer having opposite faces covered by first and second films of thin, flexible material;
• said films each having concentric inner and outer portions with said inner portion of one of said films being secured to said patch adjacent said opening;
• said one film having its outer portion unsecured to said patch to permit the outer portions of said films to be squeezed together between a user's fingers for extruding said sealant material of said second adhesive layer into said stoma opening.
