Methods, apparatuses, and systems for promoting re-epithelialization and granulation as an aspect of wound healing are presented. A method and system for promoting granulation and re-epithelialization of a wound at the same time involves using a reduced-pressure treatment dressing and applying a moist, water-sensitive barrier to promote re-epithelialization and to inhibit granulation. Other systems, apparatuses, and methods are presented.

The illustrative embodiments described herein are directed to an apparatus, system, and method for storing liquid from a tissue site. The apparatus may include a drape having an aperture, and a fluid pouch coupled to the drape such that the fluid pouch is in fluid communication with the aperture. In one embodiment, the fluid pouch is operable to transfer reduced pressure to the aperture such that the liquid from the tissue site is drawn into the fluid pouch. The fluid pouch may have a cavity that stores the liquid that is drawn from the tissue site. In another embodiment, the fluid pouch may include at least one baffle. The fluid pouch may also include a fluid channel at least partially defined by the at least one baffle. The fluid channel may be operable to store liquid from the tissue site when reduced pressure is applied through the fluid channel.

A wound healing system for promoting healing of a wound of a patient includes a positive pressure source, a reduced pressure source, and a porous foam positioned in contact with the wound. The porous foam includes a plurality of flow channels in fluid communication with the reduced pressure source. The system further includes a filler member having a flexible wall defining an interior chamber. The interior chamber is in fluid communication with the positive pressure source, and a cover member is positioned over the filler member.

Adjustable covers, systems, and methods are presented that include an adjustable cover that may be adjusted to an appropriate size by hand without requiring cutting tools and without substantial leaks. In one instance, the adjustable covering includes a drape member with a plurality of non-leaking tear paths. Each non-leaking tear path includes a weakened path of the drape member that may be torn. The adjustable covering may further include a first plurality of tear starters formed on a first initiation edge of the drape member. Each tear starter of the first plurality of tear starters is aligned with one of the plurality of tear paths. Each of the first plurality of tear starters is adapted to facilitate the initiation of a tear along a tear path. The grains of the drape member, a backing layer, and support layer may also be in the same direction. Other adjustable covers, systems, and methods are presented.

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.

A reduced pressure treatment apparatus includes a charging chamber storing a first pressure less than an ambient pressure and a regulated chamber storing a second pressure less than the ambient pressure. The first pressure is less than the second pressure. A conduit provides fluid communication between the regulated chamber and the charging chamber. A regulator member is operably associated with the conduit to prevent fluid communication through the conduit when the second pressure is less than or equal to a desired therapy pressure and to allow fluid communication through the conduit when the second pressure exceeds the desired therapy pressure.

The illustrative embodiments described herein are directed to a system and method for administering reduced pressure at a tissue site. The apparatus includes a reduced pressure source. The reduced pressure source generates a reduced pressure. The apparatus includes a tube having a plurality of lumens. The plurality of lumens includes at least one collection lumen. The reduced pressure source applies the reduced pressure to the tissue site through the plurality of lumens such that the at least one collection lumen receives fluid from the tissue site. The at least one collection lumen stores the fluid received from the tissue site.

A reduced pressure treatment system includes a porous pad positioned at a tissue site and a canister having a collection chamber, an inlet, and an outlet. The inlet is fluidly connected to the porous pad. A reduced pressure source is fluidly connected to the outlet of the canister to such that fluid from the tissue site may be drawn into the collection chamber. A hydrophobic filter is positioned adjacent the outlet to prevent liquid from exiting the collection chamber through the outlet. A baffle is positioned within the canister to create a tortuous path between the inlet and the outlet to prevent premature blocking of the hydrophobic filter.
