Abstract

An ostomy bag with a wall of a flexible material and a first coupling member for detachably coupling the ostomy bag with an implant, for example an implant surrounding the stoma, with the first coupling member being and designed with a circumferential groove. The first coupling member is a spring ring composed of a spring wire having end parts extending a distance past each other. Along the opening of the ostomy bag, an edge reinforcement is made by joining of at least a part of the spring ring and an area of the wall of the ostomy bag, and on each end part of the spring wire is a handle for opening the spring ring on overcoming the spring power in the spring ring so that the edge reinforcement can pass over the circumferential groove of the implant at mounting and decoupling of the ostomy bag. In a simple manner and without causing the stomi-operated patient any inconvenience, the ostomy bag can be coupled on for example an implant to form a tight-fitting connection between the implant and the ostomy bag, and can be quickly and easily decoupled the implant in a similarly simple manner when the ostomy bag is to be changed.

Claims11

Dependent claims

An ostomy bag comprising a flexible wall with an opening for receiving a stoma, and a coupling to couple the ostomy bag together with a substantially annular implant fitted around the stoma, the implant having an outer part that includes a circumferential groove therealong, the coupling comprising spring wire in ring form, and the spring ring having overlapping end parts shaped as handles and arranged to provide the spring ring, in a rest position, with a diameter that is smaller than that of the circumferential groove of the implant,

wherein
the ostomy bag includes an opening that is provided with edge reinforcement formed by joining at least a part of the spring ring and a portion of the flexible wall of the ostomy bag,
the edge reinforcement, upon coupling of the ostomy bag and the implant in a mounted state, is received in the circumferential groove of the implant, and
the handles are arranged such that, when pressed towards each other, the spring ring is opened sufficiently so that the spring ring and edge reinforcement each have a diameter that is larger than that of the circumferential groove of the implant to facilitate connection of the ostomy bag to the stoma or removal of the ostomy bag from the stoma.
