Reduced-pressure dressing connection pads, systems, and methods
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.
1. A connector for fluidly coupling a reduced pressure system to a tissue site, the connector comprising:
a connector body comprising a venting port and a body conduit; and
a flexible member coupled to the connector body, the flexible member having at least one venting aperture and a filter disposed in the at least one venting aperture;
wherein in response to reduced pressure supplied through the body conduit, the flexible member is adapted to move from a biased position to an unbiased position and seal the venting port.
2. The connector of claim 1 , wherein the flexible member is coupled adjacent the venting port.
3. The connector of claim 1 , wherein the flexible member is actuated by the reduced pressure supplied to the tissue site through the body conduit.
4. The connector of claim 1 , wherein the flexible member is electronically actuated.
5. The connector of claim 1 , wherein the flexible member further comprises a lip disposed proximate to the venting port, the lip sealing to a periphery of the venting port when the flexible member is in the unbiased position.
6. The connector of claim 1 , wherein the at least one aperture comprises four venting apertures equidistantly disposed about the flexible member.
7. The connector of claim 1 , wherein the flexible member has a plurality of venting apertures.
