Ostomy system
First Claim
1. An ostomy system for receiving bodily waste, comprising:
- a drainage bag;
a coupling system configured to secure the drainage bag to a stoma of a user;
a filter comprising a foam positioned at least at a filter inlet to prevent liquid and solid particles from passing from the drainage bag to its surroundings, the foam defining a passageway for releasing flatus gasses from the drainage bag to the surroundings;
wherein the filter is pre-folded and has a folding line that intersects the filter inlet of the filter, and the filter is integrated with the coupling system such that the filter inlet of the filter is inside the drainage bag and folding/unfolding the filter about the folding line moves the foam to displace faeces away from the filter inlet of the filter.

Abstract
An ostomy system for receiving bodily waste comprises a drainage bag (200) and a filter (100) comprising an open-cell foam (102) for preventing liquid and solid particles from passing from the drainage bag to its surroundings. The foam defines a passageway for releasing flatus gasses from the drainage bag to its surroundings, and at least a portion of the foam is arranged at a folding line defined by the drainage bag during use thereof. The foam may be a open-cell foam (102) embedded in a closed-cell foam (128) in a filter flange 146. A gas permeable hydrophobic membrane (127) may be provided at an outlet of the open-cell foam (102). The surroundings of the drainage bag (200) may be constituted by the interior of an outer bag.

13. A kit of parts comprising:
-
an ostomy system for receiving bodily waste including; a drainage bag; a coupling system configured to secure the drainage bag to a stoma of a user; a filter comprising a foam positioned at least at a filter inlet of the filter to prevent liquid and solid particles from exiting the drainage bag, the foam defining a passageway for releasing flatus gasses from the drainage bag; wherein the filter is integrated with the coupling system such that the filter inlet of the filter is inside the drainage bag; and a set of instructions instructing a user how to provide the drainage bag with a folding line prior to attachment of the ostomy system to the body; wherein folding/unfolding of the filter about the folding line is adapted to move the foam to displace faeces away from the filter inlet of the filter.
