AN OSTOMY APPLIANCE

摘要

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 optionally has one or more vents through which gas may escape from the bag and having a filter covering said vent wherein gas inlet and outlet openings are provided in communication with a filter body, wherein at least an area of the wall immediate opposite the inlet opening is provided with a coating reducing the friction and the cohesion between the walls wherein also a part of the inner surface of the wall comprising the inlet opening is provided with a coating reducing the surface friction coefficient. Thus the adhesion between the walls is reduced and they will then be easier to separate for the material entering a fresh bag and gravitation will then force the material against the bottom of the bag and reduce the risk of blocking of the entrance of the bag and or a filter.
