Abstract
A medical device is provided that encloses a wound and promotes wound drainage by suction. The device includes an enclosure to be placed over a wound, adhesively connected to the skin around the wound by a flange. Gauze type packing cylinders can be placed in the wound, and suction is provided either by a bulb type pump, or by a pair of regulators. When regulators are used, one alternates the suction that it provides, and the other is continuous, such that the level of suction is periodically varied. The suction facilitates the transfer of liquid from the wound to the packing cylinders and from the packing out of the enclosure. A leak detector is optionally provided.
