Abstract
A negative pressure tissue treatment system useful for negative pressure therapy includes a drape, a gasket material, a reactor housing, a reactor, and any fluid connection(s). The drape covers the skin of a patient and maintains negative pressure under the drape. The gasket material cooperates with the drape to define an enclosed volume that is scaled by the gasket material. The reactor housing defines a closed chamber in fluid communication with the enclosed volume, and the reactor is disposed in the reactor housing. The reactor consumes oxygen from a system volume defined by the enclosed volume, closed chamber, and/or any fluid connection(s). As a result of the oxygen consumption, the system volume is reduced to between about 95% to about 80% of the initial system volume.
