A reduced pressure treatment appliance is provided for treating a wound on the body of a patient. In some embodiments, the appliance comprises a cover, which is further comprised of a top cup member and an interface member. The interface member comprises flow control means, which permit exudate from the wound to flow through the flow control means into the volume under the cover, but not in the opposite direction. Also, in some embodiments, the top cup member is further comprised of a lid member, a cup body member, and lid attachment means to removably attach the lid member to the cup body member. In some of these embodiments, it is possible to access the wound for monitoring, treatment and other purposes without removing the cover from the body. In other embodiments, the wound treatment appliance also includes a vacuum system to supply reduced pressure to the site of the wound in the volume under the cover. In yet other embodiments, a suction bulb may be used to provide a source of reduced pressure to a cover that covers the wound. Finally, methods are provided for using various embodiments of the treatment appliance.
