  • Publication number: 20220379002
    Abstract: Embodiments of negative pressure wound therapy systems, apparatuses, and methods for operating the systems and apparatuses are disclosed. In some embodiments, the apparatus includes a negative pressure source, a connector port, at least one switch, and a controller. The negative pressure source is connected through the connector port to either (i) a wound dressing having a canister configured to store fluid aspirated from the wound or (ii) a wound dressing without a canister between the connector port and the wound dressing. The controller determines, based on a signal received from the at least one switch, whether the canister is positioned in the fluid flow path and adjusts one or more operational parameters of negative pressure wound therapy based on the determination. The switch is activated by the connection of either the canister or canisterless wound dressing to the apparatus.

  • Publication number: 20220218528
    Abstract: Disclosed embodiments relate to apparatuses and methods for wound treatment. In some embodiments, a negative pressure source is incorporated into a wound dressing apparatus so that the wound dressing and the negative pressure source are part of an integral or integrated wound dressing structure that applies the wound dressing and the negative pressure source simultaneously to a patient's wound. The negative pressure source and/or electronic components may be positioned between a wound contact layer and a cover layer of the wound dressing. A component may be used to prevent wound exudate from contacting the inlet of the negative pressure source.

  • Publication number: 20220211933
    Abstract: A negative pressure wound therapy system can include a source of negative pressure negative pressure configured to aspirate fluid from a wound covered by a wound dressing and electronic circuitry with a power source, boost converter circuitry configured to receive power at a first level from the power source and supply power at a second level to the source of negative pressure, the second level being higher than the first level, and a controller configured to, in response to a determination that a capacity of the power source is being depleted, cause the boost converter circuitry to supply power to the source of negative pressure at a third level lower than the second level. The controller can further lower a target negative pressure level associated with negative pressure provided by the source of negative pressure.

  • Publication number: 20220133978
    Abstract: Embodiments of negative pressure wound therapy systems and methods are disclosed. In one embodiment, an apparatus includes a driving circuit that supplies a driving signal to a negative pressure source to cause the negative pressure source to provide negative pressure via a fluid flow path to a wound dressing. The apparatus furthers include a controller that adjusts a frequency of the driving signal supplied by the driving circuit according to a comparison of a previous magnitude and a subsequent magnitude of the driving signal while the negative pressure source provides negative pressure. The transfer of power to the negative pressure source can thereby be tuned to maximize an amount of power transferred to the negative pressure source.

  • Patent number: 11305047
    Abstract: Embodiments of negative pressure wound therapy systems and methods are disclosed. In one embodiment, an apparatus includes a source of negative pressure, a coupling circuit, a driving circuit, and a controller. The driving circuit supplies a driving signal to the source of negative pressure via the coupling circuit to cause the source of negative pressure to provide negative pressure to a wound dressing. The coupling circuit includes an inductive reactance that limits a rate of change over time of the driving signal. The controller controls the driving signal supplied by the driving circuit.

  • Publication number: 20220072212
    Abstract: Embodiments of negative pressure wound therapy systems and methods are disclosed. In one embodiment, an apparatus includes a wound dressing, negative pressure source, switch, interface element, and control circuitry. The negative pressure source, switch, and interface element can be disposed on or within the wound dressing. The control circuitry can be in a first or second mode. In the first mode, the control circuitry can cause supply of negative pressure in response to a first user input via the switch when the negative pressure source is not supplying negative pressure and prevent supply of negative pressure in response to the first user input while the negative pressure source is supplying negative pressure, and the control circuitry can change from the first mode to a second mode in response to a second user input via the interface element. In the second mode, the control circuitry can disable supply of negative pressure.
