Abstract: The ostomy bag includes a multi-stage filter system that provides contamination protection for a deodorizing filter in the system. The multi-stage filter system also includes a gas transmissible protection filter that is impassible to semi-liquid waste material. The protection filter is located in the ostomy bag to precede the deodorizing filter such that gaseous waste must pass through the protection filter before it passes through the deodorizing filter. In one embodiment of the invention wherein the ostomy bag has a single chamber, the protection filter is a two layer structure with different pore counts that overlay the deodorizing filter. In another embodiment of the invention wherein the ostomy bag has dual chambers, the protection filter, without overlaying the deodorizing filter, is disposed across the flow path of gaseous waste to the deodorizing filter such that any gaseous waste that reaches the deodorizing filter must flow through the protection filter.

The second member has a projection or wall 21 dimensioned and positioned to fit between and resiliently bear against at least one of the walls when the members are connected in such a way as to make sealing engagement with at least the said one wall. The first member is of channel formation seen in cross section and has an upstanding tapering rib 24 extending from the base of the channel and between its walls. The second member has a tapering groove, of substantially complementary shape to the rib, in that surface of the rib projection or wall 21 which faces towards the first member in the mutually coupled condition of the first and second members.

Abstract: In the first embodiment, the faceplate coupling ring is of conventional design and includes an axially extending rib with a radially outwardly extending rim and a radially inwardly extending deflectable sealing strip. The pouch coupling ring includes inner and outer spaced walls, forming a channel for receiving the rib.

The protective shield is positioned onto the collection pouch with the shell portion covering the outfacing external surface of that portion of the collection pouch surrounding the neck piece. The peripheral edge contacts the collection pouch surface and straddles the neck piece.
