System and method for interfacing with a reduced pressure dressing

Abstract

Systems, devices, and methods for treating a tissue site on a patient with reduced pressure are presented. In one instance, a reduced-pressure interface includes a conduit housing having a cavity divided by a dividing wall into a reduced-pressure-application region and a pressure-detection region. The reduced-pressure interface further includes a reduced-pressure port disposed within the reduced-pressure-application region, a pressure-detection port disposed within the pressure-detection region, and a base connected to the conduit housing, the base having a manifold-contacting surface. The dividing wall includes a surface substantially coplanar with the manifold-contacting surface.
