Abstract
A device for removing fluids from a wound. The device includes a housing having therein an expandable and collapsible passive member which divides the interior of the housing into a first and a second chamber. A vacuum is applied to the second chamber to draw the passive member so as to increase the volume of the first chamber and create a negative pressure therein. Conventional wound tubing connected to the first chamber permits fluids to be drawn from the wound into the first chamber. In one exemplary embodiment a bellows is placed in communication with the second chamber.
