A mechanical wound therapy (MWT) system includes a connection for a vacuum source, which is routed through an airtight covering to a porous material positioned over the wound. The porous material may be a tubing network interspaced by a netting material constructed of biologically inert or bioabsorbable material. Alternatively, the porous material may be a layered unified dressing in which layers of mesh, netting or thin perforated film are separated and fixedly attached to functional elements of the dressing (e.g., irrigation tubing) or spacers. The vacuum and irrigation systems may be completely separated. An airtight sealing layer or foldable adhesive sealing layer may seal the dressing and facilitate sealing the dressing to the wound margins. Additional modular devices such as a wound approximating system, positive pressure bladders and adjuvant therapy modules as well as enhanced monitoring technology can be added to synergistically increase the capabilities of each dressing.

A negative pressure wound therapy system is configured for treating multiple wounds on a patient's body. The system preferably includes a source of negative air pressure, an air source, a first fluid collection volume, and a second fluid collection volume. The source of negative air pressure is in fluid communication with the first fluid collection volume, the first collection volume is in fluid communication with the second fluid collection volume, and the second fluid collection volume is in fluid communication with the air source, so that the source of negative air pressure, the first fluid collection volume, the second fluid collection volume, and the air source are fluidly connected in series.

A dressing includes a drape sealable over a wound bed, a hydrophilic foam layer coupled to the drape, a plurality of superabsorbent dots positioned between the drape and the hydrophilic foam layer, a manifold layer positioned along the hydrophilic foam layer, and a plurality of superabsorbent dots positioned between the drape and the hydrophilic foam layer. The manifold layer is substantially pneumatically isolated from the superabsorbent dots by the hydrophilic foam layer. The dressing also includes one or more channels extending through the hydrophilic foam layer and a connection pad aligned with the one or more channels. The one or more channels provide pneumatic communication between the manifold layer and the connection pad. The connection pad is coupleable to a pump operable to create a negative pressure at the manifold layer.

The multi-port therapy unit includes a plurality of patient-side ports each fluidly coupled to a plurality of conduits and a fluid reservoir fluidly coupled to the plurality of ports. A plurality of pressure sensors are associated with the plurality of patient-side ports to determining a pressure associated with each conduit. A controller is operatively coupled to the plurality of pressure sensors to receive treatment pressure data, monitor pressure for each pressure sensor of the plurality of pressure sensors, and signal an alarm condition if the pressure is outside of a pre-selected range. The system includes a reduced-pressure source fluidly coupled to a dressing at each tissue site through the multi-port therapy unit.

Provided are drainage systems that may include a drainage manifold and may be suitable for draining fluid from a tissue site. The drainage manifold may include a plurality of elongate members having a moveable end that may be adapted to configure the drainage manifold to treat a uniquely shaped tissue site. The drainage manifold may be coupled to a drainage tube with a transitional connector to provide a drainage system capable of distributing reduced pressure to the tissue site to enhance the drainage of fluids.

Some embodiments of a multi-layered dressing system for sealed wound treatment include various components used for sealing, dressing, suctioning and irrigating that are coupled together as a single, composite unit.

Embodiments described herein relate to apparatuses, systems, and methods for the treatment of wounds, for example using multiple wound dressings in combination with negative pressure wound therapy. A negative pressure would therapy apparatus can include a negative pressure source and a controller. The negative pressure source can include inlets configured to couple via fluid flow paths to wound dressings.

The controller can be configured to operate the negative pressure source and provide, based on measured pressure, indication of at least one operating condition associated with at least one of the fluid flow paths.

The present disclosure relates to a connector device for a negative pressure wound therapy system having a connector housing, a fluid outlet connected to the connector housing, an air feeding port and an air filter and coupling means. The fluid outlet is adapted to be connected to a negative pressure source. The connector device is adapted to be engaged with a wound side connector of a wound side assembly by means of the coupling means. The wound side assembly includes a fluid removing conduit and an air supplying conduit, wherein a portion of each one of the fluid removing conduit and the air supplying conduit is connected to the wound side connector. The connector device when engaged with the wound side connector, the fluid removing conduit is fluidly connected to the fluid outlet and the air supplying conduit is fluidly connected to the air feeding port such that air ambient of the connector device can be fed to the air supplying conduit via the air feeding port and the air filter.

Systems, methods and devices are provided for use in a negative pressure wound therapy system for healing a wound in a patient. Various aspects may include an ester-based material adapted to be directly applied to the wound, such as a smooth muscle fistula, without substantially damaging tissue in the wound during dressing changes. The ester-based material may have an affinity for the wound bed surface and/or wound fluid. In addition, various aspects may include a device adapted to close the wound, such as a smooth muscle fistula.

A treatment system including a tension relief layer having a central elastic region coupled between a pair of opposing wings; a porous region within the central elastic region that allows for the passage of material from an incision or wound to an upper surface of the tension relief layer; and a conformable sealing layer configured to be applied over the tension relief layer and adhered forming a sealed space around at least a portion of the wound. At least a portion of each of the opposing wings have adhesive lower surfaces. The opposing wings are configured to be stretched away from one another towards a first tensile configuration and while held in the first tensile configuration adhered to skin on opposing sides of the incision or wound.
