A medical dressing comprising a backing layer and a self-supporting substrate. The backing layers form a perimeter around the self supporting substrate and holds the self supporting substrate in place on a wound. The self supporting substrate comprises a valve. The adhesive article forms a sealed environment between the medical article and the surface surrounding the wound such that a negative pressure can be maintained in the sealed environment through the valve.
