Abstract (en)
[origin: GB2311014A] The bag comprises first and second, peripherally sealed sheets 2,4 of waterproof material, the first sheet having an opening 8 for the stoma and one of the sheets having a vent 18 covered by a flatus filter 20, and a third sheet 22 interposed between the other two sheets and sealed to the first sheet, the third sheet serving to divide the bag interior into a first waste-receiving chamber 28 in which opening 18 is located and a second chamber 30 which has an area at least as great as that of the first chamber. The third sheet has perforations, particularly fibrillations or slits, defining a primary filter 34 which allows gas to pass between the chambers, the primary and flatus filters being laterally offset so that the lateral flow path therebetween is greater than the width of the flatus filter.
