A portable system for subatmospheric pressure therapy in connection with healing a surgical wound, includes a wound dressing dimensioned for positioning relative to a wound bed of a subject, a portable subatmospheric pressure mechanism dimensioned to be carried or worn by the subject and a container for collecting exudates from the wound bed removed under the subatmospheric pressure supplied by the subatmospheric pressure mechanism. The portable subatmospheric pressure mechanism includes a housing, a subatmospheric pressure source disposed within the housing and in fluid communication with the wound dressing to supply subatmospheric pressure to the wound dressing and a power source mounted to or within the housing for supplying power to actuate the subatmospheric pressure source.

Portable wound therapy system

An apparatus for promoting the healing of an exuding wound includes a cover layer for positioning over a wound to define a reservoir over the wound. An exudate conduit having a fibrous core includes a plurality of fibers communicates with the reservoir for wicking fluids away from the wound.

Apparatus for vacuum bridging and/or exudate collection

A wound dressing has a micro-architecture to produce appropriate strains in cells to promote the healing a wound. The apparatus includes a wound cover for defining a reservoir over a wound in which a negative pressure may be maintained by forming a substantially fluid-tight seal around the wound, a vacuum source in fluid communication with the reservoir and suitable for providing an appropriate negative pressure to the reservoir to stimulate healing of the wound, and a porous structure positioned in contact with the wound for delivering micro-mechanical forces to localized areas of the wound. The porous structure comprises a three-dimensional film material having directional apertures formed therein.

Three-dimensional porous film contact layer with improved wound healing

A method of bridging from a wound dressing to a wound port for negative pressure wound therapy includes positioning an elongate wick between a wound and a remote location with respect to the wound. The elongate wick includes a three-dimensional spacer fabric having an upper fabric layer spaced from a lower fabric layer by an intermediate layer of pile threads. The elongate wick is covered with a flexible wick cover such that an enclosure is formed around the elongate wick. A substantially fluid-tight seal is established between a first end of the elongate wick cover and the wound dressing such that a reservoir is defined over the wound in which a negative pressure may be maintained. A substantially fluid-tight seal is established between a second end of the elongate wick cover and a fluid port configured for connection to a source of negative pressure.

Method and apparatus for bridging from a dressing in negative pressure wound therapy

A method for treating a wound that includes incorporating a wound dressing comprising a plurality of fibers, each fiber having a length of at least two (2) inches, into a wound to cause the walls of the wound to remain apart and allow the wound to heal from the inside to the outside, and removing the wound exudate.

Wound dressing of continuous fibers

A system to promote the healing of an exuding wound includes a wound dressing, a subatmospheric pressure mechanism, and a collection canister. The wound dressing is dimensioned for positioning relative to a wound bed of a subject. The subatmospheric pressure mechanism includes a control unit disposed within a housing. The control unit includes a vacuum source associated with a vacuum port. The collection canister has an interior wall which defines an internal chamber. The internal chamber is in fluid communication with the vacuum source of the subatmospheric pressure mechanism through the vacuum port and with the wound dressing for collecting exudates removed for the wound bed under influence of the vacuum source. The canister including a baffle mechanism disposed within the internal chamber for dampening the movement of the collected exudates.
