ABSTRACT:
The invention relates to a filtering and deodorizing device for use with a colostomy pouch. The device of the invention comprises a housing having first and second chambers in gas flow communication with one another; gas inlet means adapted for connection to the colostomy pouch, for introducing into the first chamber gas flowing from the pouch; filtering means in the first chamber for filtering gas flowing through the inlet means; deodorizing means in the second chamber for deodorizing the filtered gas flowing from the first chamber; gas control means positioned downstream of the deodorizing means and operative between open and closed positions for regulating gas build-up in the pouch; and gas outlet means for discharging the gas flowing from the second chamber when the gas control means is in the open position. Gas build-up in the pouch is released when the gas control means is in the open position so that the gas flows from the pouch through the first chamber and then through the second chamber and is evacuated as a filtered and deodorized gas through the gas outlet means.
