Abstract
An ostomy appliance with a front wall and a rear wall of flexible material forming a bag, the rear wall having an opening into the bag by which waste material can enter the bag. The bag has two or more vents through which gas may escape from the bag and a filter device covering each vent. Each filter device has gas inlet and outlet openings in communication with a respective filter body so that in use gas flows through the filter device from the inlet opening through the filter body to the outlet opening. The inlet openings communicate with the inner space of the bag and are located near the border of the bag, being spaced at an angle of at least 45 degrees along radii of a circle of reference having a perimeter concentric with the waste opening of the bag.
