Abstract
Systems, methods, and connectors are provided that introduce a working gas at certain times into a reduced-pressure dressing into order to break or avoid vacuum locks in the conduits removing fluids. In one instance, a reduced-pressure connector includes a connector body for applying a reduced pressure to the tissue site. The connector body is formed with a venting port, a body conduit, and a receptacle to receive a reduced-pressure delivery conduit. The reduced-pressure connector includes a flexible member coupled to the connector body over the venting port. The flexible member is formed with at least one venting aperture. The flexible member is biased away from the venting port and is configured to collapse and seal the venting port under a reduced pressure greater than a threshold pressure. Other systems, apparatuses, and methods are disclosed.
