  • Publication number: 20240407954
    Abstract: Apparatuses, systems, and methods for providing negative pressure therapy are described. The system includes a dressing configured to be positioned adjacent to a tissue site, and a therapy unit. The therapy unit includes a pump module and a forced air module. The pump module includes a piezoelectric pump sealed between a pump casing, and a lid. The forced air module includes a forced air device configured to generate a fluid flow and a pathway enclosure configured to form a fluid path across the lid. The system further includes a canister with a pathway connection and an airflow pathway extending through the canister. The airflow pathway is lined with an evaporative membrane configured to allow evaporated fluids in the canister to escape to ambient air. The forced air module directs the fluid flow into the canister through the pathway connection and over the evaporative membrane to maximize fluid evaporation.

  • Publication number: 20240350167
    Abstract: A wound debridement system includes a wound dressing having an active layer and a wound interface layer. The active layer is formed from one or more drive elements arranged about a film layer, by which the drive elements are attached to the wound interface layer. Activation of the drive elements is configured to cause the movement of the wound interface layer relative to a tissue site to which the wound dressing is applied. The drive elements may include one or more drive members formed of a material having a shape memory effect configured to transition the drive members between expanded and collapsed configurations and/or one or more motors configured to translate or oscillate the active layer. The wound interface layer may be formed having an abrasive wound-facing surface, such that the movement of the wound interface layer causes a mechanical disruption and debridement of debris at the tissue site.
