    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 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.
