1. A stoma valve appliance, comprising:
an annular support member configured to surround a patient stoma and having an inner, skin facing side, outer side and a central opening;
a base member removably attachable over a center of the annular support member, said base member defining a first solids and liquids flow path and a second gas vent flow path through the base member, each of the first and second flow paths having at least one opening on an inner side of the base member;
a valve disposed in the base member configured to control flow through said first flow path, the valve having an open position permitting flow and a closed position preventing flow and being manipulable between the open and closed positions by the patient;
a stem with an inlet and an outlet, the stem projecting inwardly from the base member through the central opening of the annular support member, the stem having sufficient length to extend from the central opening of the annular support member to position the inlet in the stoma when the base member is mounted on the annular support member whereby the outlet at an opposite end of the stem is configured for communicating with the first flow path opening in the base member; and
a gas permeable filter seal positioned around the stem and extending to and covering the at least one second gas vent flow path opening, whereby gasses from the stoma can be vented from the stoma through said gas permeable filter seal and said second flow path, while liquids and solids from the stoma are prevented from entering said second flow path.
