Abstract
A reduced pressure treatment appliance is provided for treating a wound on the body of a patient. In some embodiments, the appliance comprises an overlay, which is further comprised of cup members that may be detached or cut away from the overlay so that the overlay can be adjusted in size and shape. Also, in some embodiments, the overlay is further comprised of a pressure venting valve to maintain a predetermined level of reduced pressure at the site of the wound. 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 overlay. In yet other embodiments, the treatment appliance also includes wound packing means to prevent overgrowth of the wound or to encourage growth of wound tissue into an absorbable matrix comprising the wound packing means. In still other embodiments, a suction bulb may be used to provide a source of reduced pressure to an overlay that covers the wound. Finally, methods are provided for using various embodiments of the treatment appliance.
