REDUCED-PRESSURE SYSTEMS AND METHODS EMPLOYING A LEAK-DETECTION MEMBER

摘要

Systems, methods, and apparatus are provided for detecting leaks in systems for treating a patient with reduced pressure. In one instance, a system includes a distribution manifold for disposing proximate to the tissue site and a sealing member for disposing over the distribution manifold and at least a portion of intact epidermis of the patient. The sealing member has at least a portion that is substantially transparent. The system further includes a reduced-pressure source associated with the distribution manifold for providing reduced pressure to the distribution manifold and a leak-detection member sized and configured to substantially surround the distribution manifold. The leak-detection member includes a detection material that develops a color contrast when a portion is exposed to air and a portion is not exposed to air. The leak detection member works with even low flow systems. Other systems, methods, and apparatus are presented.
