Stable adhesive ostomy appliance
First Claim
1. An ostomy collecting system comprising a collecting bag having an inlet opening formed in a bag wall and connecting elements surrounding said inlet opening for connection with a stoma in a user, and a carrier device for the collecting bag, said carrier device comprising a base plate for fastening on the user and a substantially annular first flange firmly connected with the base plate via a substantially annular first connecting section, said connecting elements comprising a substantially annular second flange firmly connected with the collecting bag via a substantially annular second connecting section and adapted for removable and adhesive connection with said first flange, said first and second flanges being connected with the base plate and the collecting bag, respectively, such that the outer radius of said second connecting section exceeds the outer radius of said first connecting section by a value which at least equals the total thickness of the first and the second flanges, the adhesive connection between the collecting bag and the carrier device being provided by a layer of adhesive on said second flange capable of repeated adhesion with said first flange, said first and second flanges being both made from a flexible and resilient material capable of deformation both in the plane of the flanges and at right angles thereto, thereby providing a cantilever area to secure adsorption of load forces from the bag by the resilient first and second flanges.

Abstract
An ostomy collecting system has a collecting bag having an inlet opening in a bag wall and surrounding connecting elements for connection with a stoma, and a carrier device for the collecting bag. Which is a base plate and a substantially annular first flange connected to the base plate via a first connecting section. The connecting elements comprise a substantially annular second flange, fixedly connected to the collecting bag via a substantially annular second connecting section. The two flanges are connected with the base plate and the collecting bag, respectively, in such a manner that the outer radius of said second connecting section exceeds the outer radius of said first connecting section by a value which at least equals the total thickness of the two flanges. The collecting bag, carrier device connections is provided by adhesive on said second flange capable of repeated adhesion with the first flange, and the two flanges are made from a flexible and resilient material and can be as discs of cellular plastic material.
