Patent ID: 7722586

Claim:
An ostomy appliance comprising: a base plate, said base plate having a first hole for receiving a stoma, ureter, or catheter and an adhesive wafer having a first surface to be attached to the wearer's abdomen, back, or chest; a receiving bag releasably and reattachably attached to the base plate, said receiving bag having a second hole for receiving wastes exiting the stoma, ureter or catheter and a receiving bag bottom portion which defines a distal-most part of said receiving bag relative to said second hole; and a disposable inner bag liner forming a second bag inside the receiving bag and being releasably attachable and reattachable to the base plate in a first coupling area by a first coupling component, said disposable inner bag liner having a third hole for receiving wastes exiting the stoma, ureter or catheter and the receiving bag being releasably and reattachably attachable to the base plate by a second coupling component, the first coupling component being in the form of an adhesive flange projecting from the rim of the third hole and having a surface for releasable sealing against a second surface of the base plate facing away from the user, said inner bag liner having folds along a plurality of folding lines such that said inner bag liner is compacted lengthwise prior to use, said folds being provided between the third hole and an inner bag liner bottom portion which defines a distal-most part of the inner bag liner relative to the third hole both when the inner bag liner is folded and when the inner bag liner is fully unfolded inside the receiving bag to reach a distal-most position relative to said third hole so that, when the bag is empty and in said compacted condition, said inner bag liner bottom portion is in a folded position adjacent said third hole such that initial wastes exiting the stoma, ureter or catheter will push against said inner bag liner bottom portion thus causing said folds to unfold so that said inner bag liner bottom portion moves away from said folded position adjacent the third hole to said distal-most position relative to said third hole as the inner bag liner is filled, a closed end of the compacted inner bag liner being provided with a cover to retain said inner bag liner in said compacted condition prior to use.
