摘要： The illustrative systems, methods, and dressings for applying reduced pressure to a tissue site are presented that involve quickly removing fluids from the tissue site to reduce or avoid maceration of the epidermis. One dressing includes a dressing material for transferring the reduced pressure to the tissue site and a drape covering at least a portion of the dressing material. The dressing material includes a hydrophobic tissue-interface layer adapted to contact the tissue site. The dressing material also includes a manifold adapted to distribute reduced pressure. The manifold may be a hydrophobic layer. The dressing material also includes one or more absorbent layers adapted to absorb liquid from the tissue site via the tissue-interface layer and the manifold. Other aspects are disclosed.

摘要： A system for applying a reduced pressure at a tissue site includes a reduced pressure source, a porous pad in fluid communication with the reduced pressure source, and a drape positionable over the porous pad to seal the porous pad at the tissue site. The porous pad includes a plurality of channel walls to form a plurality of channels between the channel walls. The channel walls are substantially liquid impermeable to prevent movement of a liquid through the channel walls but are gas permeable to allow movement of a gas through the channel walls as reduced pressure is applied at the tissue site. The liquid impermeability of the channel walls and the application of reduced pressure causes flow of the liquid to occur through the plurality of channels.

摘要： A dynamic, reduced-pressure treatment system generates reduced pressure and a wave experienced at a tissue site where the wave may have a frequency in the range of from 0.5 Hertz to 20 Hertz. The system includes a manifold for delivering reduced pressure to the tissue site, a sealing member forming a fluid seal over the tissue site, a reduced-pressure source for providing reduced pressure, a reduced-pressure delivery member for delivering reduced pressure from the reduced-pressure source to the manifold, and a wave generator associated with the reduced-pressure delivery member for imparting a wave to the reduced pressure developed by the reduced-pressure source. A reduced-pressure delivery member with liquid-impermeable-and-gas-permeable element may be applied to help reduce blockages and to facilitate ease of treatment. Other systems, apparatuses, and methods are disclosed.
