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. Thus semi-liquid waste material cannot contact the deodorizing filter since it cannot bypass the protection filter to reach the deodorizing filter.
