  • Patent number: 10016539
    Abstract: A manually-actuated pump for applying reduced-pressure therapy includes a charging chamber and a regulated chamber. The charging chamber has a closed end. A regulator passage extends between the charging chamber and the regulated chamber, and a valve body is adapted to control fluid communication through the regulator passage. A regulator spring is engaged with the valve body to bias the valve body against a differential between a pressure in the regulated chamber and an ambient pressure. The manually-actuated pump also includes an outlet port coupled to the regulated chamber; and a valve assembly coupled to the charging chamber to permit fluid flow through the closed end of the charging chamber.

  • Patent number: 9975091
    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.

  • Patent number: 9974694
    Abstract: Systems, apparatuses, and methods for closing an opening through a surface of a tissue site are described. The system includes a sealing member adapted to cover the opening to form a sealed space and a negative-pressure source adapted to be fluidly coupled to the sealed space to provide negative pressure to the sealed space. The system also includes a contracting layer adapted to be positioned adjacent the opening and formed from a material having a firmness factor and a plurality of holes extending through the contracting layer to form a void space. The holes have a perforation shape factor and a strut angle causing the plurality of holes to collapse in a direction substantially perpendicular to the opening. The contracting layer generates a closing force substantially parallel to the surface of the tissue site to close the opening in response to application of the negative pressure.

  • Patent number: 9974891
    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.
