  • Publication number: 20180140814
    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.

  • Publication number: 20170333605
    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.

  • Publication number: 20170224891
    Abstract: Dressings, systems, and methods are disclosed that, in some embodiments, relate to treating a tissue site. In one embodiment, a dressing may include a manifold, a retention pouch, a sealing member, and a conduit interface. The manifold may be adapted to distribute reduced pressure to the tissue site, and the retention pouch may be adapted to retain and manage fluid extracted from the tissue site. The sealing member may cover the retention pouch and the manifold to provide a sealed space with the tissue site. The conduit interface may be in fluid communication with the sealed space and an exterior surface of the sealing member. The dressing may be utilized with a therapy device operable to control reduced pressure in the dressing and fluid flow over the sealing member.

  • Publication number: 20160067392
    Abstract: In one example embodiment, an apparatus may include a panel with integrated fluid channels, wherein the panel and the fluid channel consist only of surfaces that can be manufactured with a straight-pull mold. A port may also be integrated into the panel to facilitate coupling the fluid channel to pneumatic components in an assembly. A seal may be secured to the panel over the fluid channel to form an integrated fluid conductor. The seal is preferably an adhesive label that can also be used for product labeling. Such an apparatus may be used in a control unit of a therapy system, employing several integrated fluid conductors. A method of manufacturing may include molding a panel, wherein the mold forms a channel integral to the panel. The panel and the channel preferably consist of surfaces that can be molded with a straight-pull mold.

  • Publication number: 20160058986
    Abstract: A reduced pressure treatment system includes a liquid-collection canister for collecting liquid from a tissue site to which reduced pressure treatment is applied. The canister includes a first space configured to collect the liquid from the tissue site and a filter having a frame and a non-planar filter element. The filter defines a second space within the canister separated from the first space by the filter element. The filter element substantially prevents liquid from passing from the first space into the second space. The filter element substantially allows gaseous communication between the first space and the second space when the second space is exposed to a reduced pressure.
