Abstract: A multi-layer dressing for treating tissue with negative pressure, instillation, or both. In some embodiments a first layer may be formed from reticulated foam having a series of holes. A second layer disposed adjacent to the first layer may be formed from a perforated polymer. The dressing may optionally include a third layer formed from a soft polymer, such as a silicone gel. The third layer may also have perforations or apertures. The third layer is generally oriented to face a tissue site, and may be disposed adjacent to the first layer so that the first layer is disposed between the third layer and the first layer. The perforations or apertures in the third layer may be registered with one or more perforations in the first layer.

Abstract: A dressing for treating a tissue site may include a base layer, a sealing member, a first and a second wicking layer, and an absorbent layer. The base layer may have a periphery surrounding a central portion and a plurality of apertures disposed through the periphery and the central portion. At least one of the apertures in the periphery may be positioned at an edge of the periphery, and may have an interior exposed at the edge. The sealing member and the base layer may define an enclosure. The first and the second wicking layer may each be disposed in the enclosure with the absorbent layer positioned between the first and the second wicking layer. Other dressings, systems, and methods are disclosed.

Abstract: A valve arrangement for administering an instillation and/or negative pressure therapy through at least a first wound dressing and a second wound dressing includes a valve arrangement including a first flow path, a first valve, a second flow path, and a second valve. The first flow path extends between a source port and a first wound dressing port structured for fluid communication with the first wound dressing. The first valve is positioned in the first flow path. The second flow path extends between the source port and a second wound dressing port structured for fluid communication with the second wound dressing. The second valve is positioned in the second flow path.

Abstract: A negative pressure wound therapy device includes a piezoelectric pump, a state detector configured to detect a state of the pump, and a control circuit configured to transmit a first control signal for a first period having a first RMS voltage greater than or equal to a threshold voltage at which driving the pump for a second period greater than the first period can cause the pump to emit sound at a magnitude greater than a sound threshold; receive a first indication of the state; determine if the pump is in a leak condition; transmit, responsive to the pump not being in the leak condition, a second control signal having a second RMS voltage less than the first RMS voltage; and transmit, responsive to the pump being in the leak condition, a third control signal having a third RMS voltage greater than the second RMS voltage.

Abstract: A transfer dressing that can secure and/or prevent undesired movement of epidermal skin grafts transfer substrates is described. The transfer dressing can include a transfer substrate and one or more adhesive appendages that are configured to secure the transfer substrate to a recipient site (e.g., periwound area) in order to hold the transfer substrate in place and/or facilitate handling of the transfer substrate. The transfer substrate can be comprised of a fenestrated surface configured to facilitate harvesting and transfer of epidermal skin grafts.

Abstract: Some illustrative embodiments of a dressing for treating a tissue site may include a fluid hub, a plurality of elongate fluid members, and a separable joint. The plurality of elongate fluid members may be positioned in fluid communication with the fluid hub. Each of the plurality of elongate fluid members may include a proximal end, a distal end, and an elongate side between the proximal end and the distal end. The elongate side of the elongate fluid members may extend longitudinally outward from the fluid hub. The separable joint may be coupled between the elongate side of one of the plurality of elongate fluid members and the elongate side of another of the plurality of elongate fluid members. Other dressings, systems, and methods are disclosed.
