IMPROVED DRESSINGS AND SYSTEMS FOR NEGATIVE-PRESSURE WOUND THERAPY AND INSTILLATION THERAPY HAVING LOW-VOLUME MANIFOLDS AND BYPASS INSTILLATION PASSAGES

Abstract: a system for treating a tissue site with negative-pressure therapy includes a dressing configured to be placed adjacent to the tissue site. the dressing includes a first film layer, a manifold, and a second film layer. a plurality of fenestrations is disposed through a first side and a second side of the first film layer and is configured to be exposed to the tissue site. the first side of the manifold is disposed adjacent to the second side of the first film layer, and a first side of the second film layer is disposed adjacent to the second side of the manifold. a negative-pressure passage is disposed through the second film layer, and a fluid-ingress passage is disposed through the second film layer, the manifold, and the first film layer. a negative-pressure source is fluidly coupled to the negative-pressure passage, and a fluid source coupled to the fluid-ingress passage.
