  • Patent number: 11819445
    Abstract: An accessory separate from and attachable to an adhesive body side member of an ostomy appliance is disclosed. The accessory includes a proximal surface that is attachable to a distal side of the adhesive body side member and a distal surface opposite from and connected to the proximal surface. The accessory has a pocket formed between the proximal surface and the distal surface of the accessory, with an opening formed to communicate with the pocket, and manipulable material disposed in the pocket. The manipulable material is adapted to be displaced out of the pocket through the opening and is adapted to absorb stoma moisture to prevent the stoma moisture from reaching an adhesive of the adhesive body side member to effectively increase a wear time of the adhesive body side member.

  • Patent number: 11583431
    Abstract: Disclosed is a complementary-material element (22) attachable to a base plate (24) of an ostomy appliance (20) and including a first entity (30) and a second entity (32). The entities comprise different material compositions. The material composition of the second entity comprises a neutralizer which is released from the complementary-material element in response to moisture, thereby neutralizing the damaging effects of stomal output.
