  • NEGATIVE-PRESSURE THERAPY WITH OXYGEN
    Publication number: 20210085839
    Abstract: Systems, apparatuses, and methods for providing negative-pressure therapy with oxygen therapy are claimed. An apparatus for providing negative pressure therapy with normobaric or hypobaric oxygen therapy may include dressing having a tissue interface and a cover. Additionally, in some embodiments, the apparatus may include a negative-pressure source and an oxygen-concentrating or oxygen-generating source, each of which may be coupled to or configured to be coupled to the tissue interface. The tissue interface can enable fluid transport during negative-pressure therapy cycles, and disbursement of normobaric or hyperbaric oxygen during oxygen therapy cycles. For example, some embodiments of the tissue interface may comprise structures or foams constructed from polyurethane, silicone, or polyvinyl chloride.

  • Manually-actuated reduced pressure treatment system having regulated pressure capabilities
    Patent number: 10946122
    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.
