<p>An ostomy appliance comprising a front wall and a rear wall of flexible material forming a bag, the rear wall having an inlet opening into the bag by which waste material can enter the bag and one of the walls having one or more vents through which gas may escape from the bag and optionally having a filter covering said vent and having an outlet opening, wherein the appliance is provided with a flap being sealable to the wall in a manner in which the flap is covering the outlet opening of the filter and furthermore to be a sealed to the wall in a manner wherein the flap is shifted to the side so that outlet opening of the filter is partially or fully open which device is characterised in that one end of the flap is sealed to the wall in a manner allowing a pivoting of the flap in the plane of the wall and that the flap has a surface which may be releasably sealed to the wall reduces the risk of adhesion between the walls of the receiving bag due to very low production of flatus causing vacuum-like condition in the bag and thus reduces the risk that visceral contents reaching the opening of the stoma will not inmediately be able to separate the walls and 'fall' into the bottom of the receiving bag but will rather stay and block the entrance to the bag and, at the same time, gives the option of allowing a minor amount of gas to pass out of the ostomy appliance according to need to avoid ballooning.</p> |
