    Abstract: A negative pressure wound therapy device, kit, and method are provided for improved treatment of wounds on complex three-dimensional anatomies. The device includes a conformable manifold made of a porous and permeable material with a pattern of cuts designed to transform the manifold from a relaxed, planar state to a pliable three-dimensional state when extended along the lateral axis. The kit further may include a wound interface layer, an adhesive, breathable drape, and a pneumatic connection to a negative pressure wound therapy device. Finally, a method for treating wounds using reduced pressure and the presently disclosed kit is provided.

    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 negative pressure wound therapy system includes at least one sensor coupled to a wound dressing for a wound of a patient, and a processing circuit. The at least one sensor is configured to output a measurement of the pressure in the wound dressing. The processing circuit is configured to open a sealable aperture, receive the pressure measurements in the wound dressing, calculate a rate of pressure decay, correlate the rate of pressure decay in the wound dressing to a wound dressing fluid absorbent capacity and other therapy parameters, and output the wound dressing fluid absorbent capacity and other therapy parameters to a remote electronic device.

    Abstract: A system, apparatus, and method for treating a tissue site with reduced pressure includes a connector having a connector body. The connector body includes a cavity and a cavity aperture. The connector also includes a conduit port fluidly coupling a conduit to the cavity. The connector further includes a base adjacent the cavity aperture that is configured to be positioned adjacent a drape. The cavity is configured to be fluidly coupled to a manifold through an aperture of the drape. The connector also includes a sensing probe having a proximal end configured to be fluidly coupled to the conduit and a distal end extending to the cavity aperture. The distal end is configured to be positioned adjacent to and in fluid communication with a manifold.

    Abstract: A reduced-pressure system for delivering reduced pressure for medical purposes to a desired site and to receive fluids in one instance includes a reservoir having an interior space operable to contain the fluids. A reduced-pressure delivery conduit is placed in fluid communication with the interior space for delivering the reduced pressure to the desired site. A source conduit and a pressure sensor conduit are placed in fluid communication with the interior space. A pressure sensor is placed in fluid communication with the pressure sensor conduit. A reduced-pressure source is placed in fluid communication with the source conduit. A reduced-pressure control unit is associated with the pressure sensor and the reduced-pressure source and is operable to receive pressure data from the pressure sensor and supply data from the reduced-pressure source and to determine when a reservoir-full/blockage condition exists. Other systems and methods are presented.

    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 negative pressure wound therapy (NPWT) device includes a canister, a pump, a filter, and a control unit. The canister is configured to collect wound exudate from a wound site. The pump is fluidly coupled to the canister and configured to draw a vacuum within the canister by pumping air out of the canister. The filter is positioned between the canister and the pump such that the air pumped out of the canister passes through the filter in a first direction. The control unit is configured to operate the pump and to purge the filter by causing airflow through the filter in a second direction, opposite the first direction.
