Abstract
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 he used lo provide a source of reduced pressure to the cover. Additionally, methods are provided for using various embodiments of the treatment appliance.

16. A method of treating a wound, comprising:
-
positioning a membrane into contact with the wound;
positioning a wound cover over the wound, the cover having a rigid or semi-rigid ring sized to contact skin surrounding the wound so as to create a relatively fluid-tight seal;
applying reduced pressure to the wound through a port on the wound cover to draw fluid from the wound through the membrane;
collecting fluid from the wound in a space between the cover and the membrane; and
preventing the collected fluid from flowing through the port. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A method for the treatment of a wound on a body, the method comprising:
-
positioning a flexible membrane in contact with the body, the flexible membrane forming a seal with the body;
placing a wound cover over the wound to enclose the wound, the wound cover forming a reversible seal with the flexible membrane; and
applying negative pressure to the wound through the wound cover and the flexible membrane;
wherein the wound cover is removable from the flexible membrane while the flexible membrane remains sealed with the body. - View Dependent Claims (30, 31, 32, 33)
