    Abstract: A tubeset module includes one or more elements of a negative pressure wound therapy (“NPWT”) system, such as a valve, a calibrated leak, a pressure sensor, etc. The tubeset module may communicate with a controller of the NPWT system via a communications interface provided by the tubeset module. The communication between the tubeset module and the controller may be used to fully automate one or more processes involving the operation of the components of the NPWT system included in the tubeset module, allowing the NPWT system to, e.g. estimate a wound site volume, estimate a volume of fluid to be instilled, monitor wound healing progression, etc. without requiring any user interaction or involvement. The tubeset module may be defined by one or more housing elements. The tubeset module may be incorporated into any of the tubing, fluid canister, wound dressing and/or therapy device housing components of the NPWT system.

    Abstract: A wound therapy system includes a negative pressure circuit, a pump, a pressure sensor, and a controller. The negative pressure circuit applies negative pressure to a wound. The pump is fluidly coupled to the negative pressure circuit and produces a negative pressure at the wound or within the negative pressure circuit. The pressure sensor measures the negative pressure within the negative pressure circuit or the wound. The controller performs a testing procedure including a first drawdown period, a leak rate determination period, a vent period, and a second drawdown period. The controller is configured to receive one or more pressure measurements of the pressure sensor over the leak rate determination period to determine a leak rate parameter, monitor an amount of elapsed time over the second drawdown period to determine a drawdown parameter, and estimate a volume of the wound based on the leak rate parameter and the drawdown parameter.

    Abstract: A wound therapy system includes a dressing an instillation pump fluidly communicable with the dressing and configured to provide instillation fluid to the dressing, a negative pressure pump fluidly communicable with the dressing and configured to remove air from the dressing, and a control circuit communicably coupled to the instillation pump and the negative pressure pump. The control circuit is configured to control the instillation pump to provide an amount of the instillation fluid to the dressing, provide a soak period, and control the negative pressure pump to provide a cyclic variation of negative pressure at the dressing.

    Abstract: A volume of a wound is estimated using a dynamic pressure response measured during instillation of fluid to the wound using a negative pressure wound therapy system. A previously estimated wound volume may be used to detect and prevent overfill of fluid to the wound during future instillation events. For example, real-time pressure measurements may be compared to model data representative of expected pressure at a wound having a volume equal to the previously estimated wound volume, with instillation being stopped if the observed pressure varies from the expected pressure. A comparison of a total volume of fluid instilled to the wound may also be compared to the previously estimated wound volume to prevent overfill. The comparison of wound volume estimated based on an instillation event may also be compared to a wound volume estimated using other methods to provide a higher confidence wound volume estimate.

    Abstract: A wound therapy system includes a negative pressure circuit, a pump, a pressure sensor, and a controller. The negative pressure circuit applies negative pressure to a wound. The pump is fluidly coupled to the negative pressure circuit and produces a negative pressure at the wound or within the negative pressure circuit. The pressure sensor measures the negative pressure within the negative pressure circuit or the wound. The controller performs a testing procedure including a first drawdown period, a leak rate determination period, a vent period, and a second drawdown period. The controller is configured to receive one or more pressure measurements of the pressure sensor over the leak rate determination period to determine a leak rate parameter, monitor an amount of elapsed time over the second drawdown period to determine a drawdown parameter, and estimate a volume of the wound based on the leak rate parameter and the drawdown parameter.

    Abstract: A modular wound therapy training device, system, and method of use for the device are provided. The device may include a support tray, an elastic insert, a base within the elastic insert, a recess within the base, a conformable polymer, a dressing and a negative pressure source. The recess may be circumferentially smaller than the base and the conformable polymer may be sized to fit within the recess. The device is preferably sized and shaped to form a system when aligned and assembled with duplicates of the device. A method is provided to apply negative pressure and installation therapy when a negative pressure source is activated through a protective dressing.
