Abstract: A dressing for treating a tissue site may include a base layer, a sealing member, a first and a second wicking layer, and an absorbent layer. The base layer may have a periphery surrounding a central portion and a plurality of apertures disposed through the periphery and the central portion. The apertures in the periphery may be larger than the apertures in the central portion. The sealing member and the base layer may define an enclosure. The first and the second wicking layer may each be disposed in the enclosure with the absorbent layer positioned between the first and the second wicking layer. Other dressings, systems, and methods are disclosed.

Abstract: A system is described herein that can irrigate a tissue site using negative-pressure. The system may include a tissue interface configured to be placed adjacent to the tissue site, and a sealing member configured to be placed over the tissue interface to form a sealed space. The system may also include a negative-pressure source configured to be fluidly coupled to the sealed space and a fluid source. The system may further include an irrigation valve. The irrigation valve can have a fluid inlet configured to be fluidly coupled to the fluid source. The irrigation valve can also have a fluid outlet configured to be fluidly coupled to the sealed space. The irrigation valve may also include a clamp configured to be actuated by the negative-pressure source to regulate fluid flow from the fluid source through the fluid outlet.

Abstract: A canister for use in administering reduced pressure to a tissue site includes a center body, a first end cap, and a second end cap. The center body includes a first end, second end, and a number of fluidly separate body conduits. The first end cap is connected to the first end of the center body and includes a number of return conduits fluidly connecting one body conduit to another. The first end has a port for receiving a conduit in fluid communication with the tissue site. The second end cap is connected to the second end of the center body and includes a number of return conduits fluidly connecting one body conduit to another. The second end cap has a port for receiving a conduit in fluid communication with a reduced pressure source. The fluid connection between the body conduits and the return conduits creates a continuous, tortuous pathway.

Abstract: A low-profile reduced pressure treatment apparatus and system are provided. The apparatus includes a moldable conduit holder, a conduit through the conduit holder, and a flexible base. The conduit holder has first and second bulkhead surfaces, a convex top surface, and a bottom surface adapted to conform to a tissue contact region adjacent to a tissue site. An end of the conduit is substantially flush with the first bulkhead surface and a longitudinal axis of the conduit is substantially perpendicular to the first and second bulkhead surfaces. The base is connected on a first side to the bottom surface of the conduit holder, and extends beyond the first bulkhead surface to form an overlay zone adjacent the first bulkhead surface. An adhesive is disposed on a second side of the flexible base to secure the flexible base to the tissue contact region.

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 system and method for providing fluid to a tissue site is described. The method fluidly couples an instillation therapy system to the tissue site and monitors a pressure supplied to the tissue site by a reduced-pressure source with the instillation therapy system for a time period. The method provides fluid to the tissue site with the instillation therapy system in response to the pressure at the tissue site during the time period. The system includes a pressure sensor fluidly coupled to the tissue site to measure a pressure proximate the tissue site. A valve and a flow meter are fluidly between a fluid reservoir and the tissue site. A controller is communicatively coupled to the pressure sensor and the valve and configured to monitor the pressure at the tissue site and a volume of fluid flow to the tissue and, in response, operate the valve.

Abstract: Systems, methods, and devices related to removing fluids from a patient are provided. In one instance, fluid is removed from the patient and delivered to a canister using reduced pressure. Reduced pressure is supplied to the canister via a reduced-pressure delivery conduit that includes a moisture processing device and a hydrophobic filter. The moisture processing device condenses moisture from the air to prevent condensation from occluding the hydrophobic filter. The moisture processing devices includes an expanded volume and one or more liquid-impermeable, vapor-permeable membranes. The liquid-impermeable, vapor-permeable membrane allows vapor to egress the moisture processing device. Other systems, methods, and devices are presented.

Abstract: 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.

Abstract: Systems, methods, and dressings for treating a linear wound, such as an incision, on a patient are presented. The systems, dressings, and methods involve a sealed wound dressing assembly that helps form a fluid seal around the linear wound while simultaneously encompassing a subcutaneous delivery conduit to deliver fluid to or from a subcutaneous tissue site. In one instance, a reduced-pressure interface is used to allow the subcutaneous delivery conduit to pass through tissue at or near the linear wound and through a wound dressing assembly to a drainage receptacle.
