Abstract: In one example embodiment, an apparatus for treating a tissue site may include a contact layer formed from a compressible material. The contact layer may include a plurality of apertures extending at least partially through the contact layer. The contact layer may be configurable such that at least a portion of the apertures include a first plurality of orifices having a diameter in a first diameter range and such that at least a portion of the apertures include a second plurality of orifices having a diameter in a second diameter range. The first diameter range may be from about 2 mm to about 6 mm. The second diameter range may be from about 8 mm to about 15 mm. The apparatus may include a cover configured to form a sealed space including the contact layer and the tissue site.

Abstract: A pump generates a vacuum at a wound site via first tubing. A negative pressure circuit is defined by a canister, the first tubing and the wound site. A controller of a therapy device operates the pump to apply a first negative pressure to the entirety of the negative pressure circuit, following which ambient air is allowed to flow into the negative pressure circuit. The controller also operates the pump to apply a second negative pressure to a selected portion of the negative pressure circuit exclusive of the wound site, following which ambient air is allowed to flow into the selected portion. A quantity of fluid to be delivered to the wound site via a second tubing is determined by comparing measured parameters related to the flow of air into the negative pressure circuit to parameters measured with respect to the flow of air into the selected portion.

Abstract: A dressing includes a foam layer, a plurality of cores extending substantially through the foam layer, and a drape sealable over the foam layer and a wound bed. The drape is couplable to a pump operable to create a negative pressure in the substantially-airtight volume. Each core is substantially removable from the foam layer to reveal a channel through the foam layer. Each core is defined by perforations that facilitate separation of the core from the foam layer.

Abstract: A dressing interface for connecting a negative-pressure source to a dressing may have a coupling member comprising an aperture, a first adhesive region having a first region peel strength, and a second adhesive region having a second region peel strength less than the first region peel strength. The dressing interface may further have a flange coupled to the coupling member, and a conduit housing coupled to the flange and extending through the aperture in the contact layer.

Abstract: The present disclosure relates to a network system. The system is formed by at least two negative pressure wound therapy (NPWT) devices. The first NPWT device includes a wireless radio, user interface, controller, and processing circuit. The wireless radio wirelessly communicates with the second NPWT device. The user interface displays operational status of therapy operation, receives a command of operational change from a user, and displays wireless radio connection strength between the first NPWT device and the NPWT device. The controller controls therapy operation of the first NPWT device based on input from the user interface. The processing circuit causes the wireless radio to communicate with the second NPWT device, determines wireless radio connection strength between the first NPWT device and the second NPWT device based on communication between the first NPWT device and the second NPWT device, and causes the user interface to display determined wireless radio connection strength.

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 cutting template for use with a negative pressure wound therapy system includes a substantially rigid body. The body includes a top surface, a bottom surface, a height, and a recess. The top surface is configured to engage a drape layer. The bottom surface is configured to engage a dressing layer. The height is defined between the top surface and the bottom surface. The height is configured to create a gap between the drape layer and the dressing layer. The recess is disposed substantially about a perimeter of the body. The recess is configured to receive an edge of a cutting tool so that an opening is formed in the drape layer when the edge is traversed about the perimeter.
