    Abstract: One implementation of the present disclosure is a negative pressure wound therapy (NPWT) device. The NPWT device is configured to perform NPWT and includes a battery configured to supply the NPWT device with power, a pump configured to receive power from the battery and to produce a vacuum at a setpoint pressure to perform the NPWT, a user interface configured to provide alerts to a user, and a controller configured to receive power from the battery and to adjust the setpoint pressure of the pump. The controller is configured to operate the NPWT device in a standard therapy mode, a seal assist therapy mode, a pressure optimization mode, and a preservation mode of operation.

    Abstract: A wound debridement system includes a wound dressing having an active layer (40) and a wound interface layer (10). The active layer is formed from one or more pneumatic members (45). The pneumatic members are arranged about a film layer (60), by which the pneumatic members are attached to the wound interface layer. A control unit (80) controls a drive unit (70) to intermittently apply pressure to the pneumatic members of the active layer. The pressure applied by the drive unit causes the pneumatic members to expand and contract. This movement of the pneumatic members is transferred to the wound interface layer, causing the wound interface layer to move relative to a tissue site to which the wound dressing is applied. 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.

    Abstract: One implementation of the present disclosure is a method for dynamically controlling an alarm of a negative pressure wound therapy (NPWT) device, according to some embodiments. In some embodiments, the method includes initiating NPWT, comparing an initial pump duty to a threshold value to determine a dressing application quality, monitoring a leakage rate of the NPWT, setting a leak threshold value based on the dressing application quality, determining leakage event occurrences in response to the leakage rate exceeding the leak threshold value at multiple times, adjusting the leak threshold value based on at least one of a number of the leakage events over the time period, a time duration between sequentially occurring leakage events of the leakage events, and the dressing application quality, and causing a user interface device to display a leak alert in response to the leakage rate exceeding the adjusted leak threshold value.

    Abstract: A releasable connector for a negative pressure wound therapy system having a drape and a tube includes a base and a tube fitting. The base is configured to be coupled to the drape such that a substantially air-tight seal is formed between the base and the drape. The base includes a base locking member. The tube fitting is configured to be coupled to the tube such that a substantially air-tight seal is formed between the tube fitting and the tube. The tube fitting includes a tube locking member. The tube fitting is further configured to be selectively coupled to the base through an interaction between the tube locking member and the base locking member such that a substantially air-tight seal is formed between the tube fitting and the base.

    Abstract: A system for providing instillation fluid to a deep abdominal wound includes an instillation module and a connection structure. The instillation module defines a first surface and a second, abdominal contents-facing surface. The instillation module includes a distribution hub configured to receive instillation fluid from an instillation fluid source. The connection structure includes a first surface, a second, abdominal contents-facing surface; and a flow path extending between the first surface and the second surface. The flow path includes an inlet configured to receive an instillation fluid conduit engaged with the instillation fluid source and an outlet in fluid communication with the instillation module. The flow path defines an axis extending between the inlet and the outlet. The flow path is configured to compress in a direction defined by the axis.

    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.
