Abstract: Systems, methods, and apparatuses are presented that facilitate the provision of reduced pressure to a tissue site by using a delivery-and-fluid-storage bridge, which separates liquids and gases and provides a flow path for reduced pressure. In one instance, a delivery-and-fluid-storage bridge includes a delivery manifold for delivering reduced pressure to a treatment manifold at the tissue site and an absorbent layer proximate the delivery manifold adapted to receive and absorb liquids. The delivery manifold and the absorbent layer are encapsulated in an encapsulating pouch. A first aperture is formed proximate a first longitudinal end of the delivery-and-fluid-storage bridge for fluidly communicating reduced pressure to the delivery manifold from a reduced-pressure source, and a second aperture is formed on a patient-facing side of the delivery-and-fluid-storage bridge. Reduced pressure is transferred to the tissue site via the second aperture. Other systems, apparatuses, and methods are disclosed.

The contact layer may be configurable such that at least a portion of the apertures include a first plurality of orifices having a diameter in a first diameter range and such that at least a portion of the apertures include a second plurality of orifices having a diameter in a second diameter range. The first diameter range may be from about 2 mm to about 6 mm. The second diameter range may be from about 8 mm to about 15 mm. The apparatus may include a cover configured to form a sealed space including the contact layer and the tissue site.

Abstract: 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.

Abstract: A method of treating a tissue site is provided. The method includes applying a reduced pressure to a tissue site with a reduced pressure source. A source pressure is monitored at the reduced pressure source, and a differential pressure is determined between the source pressure and the desired tissue site pressure. If a blockage is present between the reduced pressure source and the tissue site, the differential pressure is limited to a first maximum differential pressure. If no blockage is present between the reduced pressure source and the tissue site, the differential pressure is limited to a second maximum differential pressure.

Abstract: A method and apparatus for disrupting material at a tissue site is described. A contact layer may be selected for use on the tissue site and positioned adjacent to the tissue site. The contact layer may include walls defining a plurality of through-holes. A sealing member may be positioned over the contact layer and sealed to tissue surrounding the tissue site to form a sealed space enclosing the contact layer. A negative-pressure source may be fluidly coupled to the sealed space. The negative-pressure source may supply negative pressure to the sealed space and the contact layer to draw tissue into the through-holes to form nodules. The negative pressure may be vented from the sealed space to release the nodules.

Abstract: In one example embodiment, a system for treating a tissue site is disclosed comprising a dressing adapted to contact the tissue site and provide a fluid seal between a therapeutic environment and a local external environment, and a solution source fluidly coupled to the dressing and adapted to deliver an antimicrobial solution comprising a peroxy ?-keto carboxylic acid, such as peroxy pyruvic acid, to the tissue interface. The system may further comprise a negative-pressure source fluidly coupled to the dressing and adapted to provide negative pressure to the therapeutic environment after delivery of the antimicrobial fluid to the therapeutic environment.
