Abstract
A valve device which permits an ostomate to selectively filter and vent gas from an ostomy appliance. The appliance comprises as a first coupling member a surgical dressing having an adhesive layer and a flange having an upstanding annular wall or projection. The annular wall has one or more openings leading to a filter compartment. The openings are controlled by valves operated by means of a push button at the outer edge of the filter compartment. The adhesive layer and the flange have an aperture so that the dressing can be attached to the body around the stoma. This first coupling member is employed in conjunction with a second coupling member which is an ostomy bag having a channel surrounding the stomal bag opening which sealingly engages the upstanding annular wall of the first coupling member.
