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 can have a top cup member and an interface member. The interface member can have flow control means, configured to 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 can have a lid member, a cup body member, and lid attachment means to removably attach the lid member to the cup body member. In some embodiments, the cover can be configured to facilitate access to the wound for monitoring, treatment and other purposes without removing the cover from the body. The wound treatment appliance can have a vacuum system to supply reduced pressure to the site of the wound in the volume under the cover. A suction bulb can be used to provide a source of reduced pressure to the cover. Additionally, methods are provided for using various embodiments of the treatment appliance.
