Ostomy appliance and filter assembly with bypass venting

An ostomy appliance comprising:

• a pouch wall defining at least a portion of a collection chamber configured to collect and store effluent from a stoma;
• an inlet formed in the pouch wall configured to be secured around the stoma;
• and
• a filter assembly comprising:
• a filter, a valve and a bypass venting chamber extending between the filter and the valve,
• wherein the valve comprises:
• a closed configuration in which gas flow from the collection chamber to the bypass venting chamber through the valve is restricted;
• and
• an open configuration in which the collection chamber and the bypass venting chamber are in fluid communication with one another such that gas is received in the bypass venting chamber from the collection chamber through the valve,
• wherein the filter comprises:
• an active gas inlet section configured to receive gas from the collection chamber;
• a bypass gas inlet section configured to receive gas from the bypass venting chamber, wherein gas enters the bypass venting chamber from the collection chamber through the valve in the open configuration, and wherein the active gas inlet section is at a different location on the filter from the bypass gas inlet section;
• and
• a filter outlet section for exiting gas to the atmosphere, and
• wherein, in an active venting state, the filter assembly is configured to allow gas from the collection chamber to flow toward the filter through the active gas inlet section and through the filter to exit the filter through the filter outlet section with the valve in the closed configuration, and wherein the filter extends from the bypass venting chamber to the filter outlet section.
