Abstract: New and useful systems, apparatuses, and methods for providing negative-pressure therapy with instillation of topical treatment solutions are described. An apparatus may comprise an exudate container, a solution source, and a pneumatically-actuated instillation regulator. The instillation regulator may be coupled to the exudate container and to the solution source, and negative pressure from a negative-pressure source can actuate the instillation regulator. In some embodiments, a negative-pressure source may be configured for a negative-pressure interval and a venting interval, and the instillation regulator can be configured to draw instillation solution from the solution source during a negative-pressure interval and to instill the solution to a dressing during a venting interval.

Abstract: In some illustrative embodiments, a system suitable for treating a tissue site may include a dressing, a low-profile conduit, a conduit interface, and a reduced-pressure source. The dressing may be adapted for positioning at the tissue site. The low-profile conduit may be adapted for fluidly coupling to the dressing. The low-profile conduit may include a manifold and a sealing member encapsulating the manifold. The conduit interface may be adapted for fluidly coupling to the low-profile conduit. The conduit interface may be in fluid communication with the dressing through the low-profile conduit. The reduced-pressure source may be adapted for fluid communication with the conduit interface. Other systems, devices, and methods are disclosed.

Abstract: Systems, methods, and apparatuses for irrigating a tissue site are described. The system can include a tissue interface and a sealing member configured to be placed over the tissue site to form a sealed space, and a negative-pressure source fluidly coupled to the sealed space. The system includes an irrigation valve having a housing, a piston disposed in the housing, a fluid inlet to fluidly couple a fluid inlet chamber to a fluid source, and a fluid outlet to fluidly couple a fluid outlet chamber to the sealed space. A piston passage extends through the piston and fluidly couples the fluid inlet chamber and the fluid outlet chamber, and a biasing member is coupled to the piston to bias the irrigation valve to a closed position. The negative-pressure source is configured to move the piston between the closed position and an open position to draw fluid to the sealed space.

Abstract: A wound therapy system and method for clearing fluids from a conduit includes a wound dressing apparatus, a pneumatic pump, a valve, and a controller. The wound dressing apparatus is fluidly coupled to a wound, the pump, and the valve. The controller is configured to determine a volume of instillation fluid that has been delivered to the wound, to operate the pneumatic pump and the valve to apply a negative pressure to the wound dressing apparatus to purge a first portion of the instillation fluid, and to operate the pneumatic pump and the valve during a purge operation to deliver a volume of air through the wound dressing apparatus that is approximately equal to or greater than the volume of instillation fluid to purge a second portion of the instillation fluid from the wound dressing apparatus.

Abstract: This disclosure includes wound dressings (18) and systems (10) with therapeutic gas and negative pressure sources for incision management. The dressing, which are configured to be coupled to tissue to facilitate delivery of oxygen to the tissue, comprise a manifold configured to permit communication of oxygen to the tissue the manifold (46) defining: a plurality of gas passageways (50); and a plurality of openings (62), one or more of which comprises a length (66) and a width (70) that is at least 50 percent less than the length; and a gas-occlusive layer (86) configured to be disposed over the manifold and coupled to the tissue such that an interior volume containing the manifold is defined between the gas-occlusive layer and the tissue and the gas-occlusive layer limits escape of oxygen from the interior volume.

Abstract: A cover for protecting a tissue site may comprise a shell layer, an adhesive disposed on the shell layer, and a contact layer disposed adjacent to the adhesive. The contact layer may have a first pattern of apertures and bridges, and the shell layer may have a second pattern of apertures overlaying the bridges. In some examples, the adhesive may have a bond strength that is greater than the tensile modulus of the shell layer. The contact layer may have an open area of about 40 percent to about 50 percent of the total area of the contact layer. A release liner may be disposed adjacent to the contact layer. Perforations through the shell layer and the contact layer can define a sacrificial segment configured to be separated from the shell layer and the contact layer. A handling bar may be coupled to the sacrificial segment.
