The described invention is a negative pressure wound therapy device designed for easy application to small to large wounds. The negative pressure device piece applies a vacuum to a wound and absorbs excess exudate or moisture. The negative pressure device comprises a sensor, battery, and small PCBA to monitor the pressure in the dressing and to alert a user when the dressing needs to be changed.

A dressing or wound filler comprising a laminate structure of film materials. In one example embodiment, a dressing may include a first layer comprising a first film, a second layer adjacent to the first layer and comprising a second film, and a third layer comprising a material having closed cells. The first layer may further include a plurality of fluid restrictions. The second layer may include blisters and apertures to allow fluid transfer through the second film. The third layer may include closed cells and apertures between the closed cells to allow fluid transfer through the third layer. The dressing may further include a fourth layer adjacent to the third layer opposite the second layer, which may include a fourth film having blisters and apertures. The dressing may also include a fifth layer, which may be adjacent to the fourth layer opposite the third layer. The fifth layer may include a film and a second plurality of fluid restrictions.

Disclosed embodiments relate to apparatuses for wound treatment. In certain embodiments, a negative pressure wound therapy apparatus includes one or more electronic components configured to be incorporated into layers of the wound dressing or integrated on top of the wound dressing. In some embodiments, a negative pressure source is incorporated into the wound dressing. The negative pressure source can be sealed between two moisture vapor permeable cover layers or enclosed in a moisture vapor permeable pouch, and may be received in a recess of an absorbent layer or spacer layer of a wound dressing apparatus.

Wound therapy compression garments and layered dressing kits are described. In an aspect, a kit includes a compression garment and one or more fenestrated dressing layers. The compression garment includes a plurality of hydrophobic longitudinal wales arranged to form a fabric with a plurality of hydrophilic transverse elastomeric threads under variable tension connecting adjacent ones of the hydrophobic longitudinal wales in such way as to deliver elastic compression at a wound site. The hydrophobic longitudinal wales and the hydrophilic transverse elastomeric threads cooperate to generate hydrostatic pressure for transporting fluid away from the wound site. The fenestrated dressing layer(s) is configured to form a textured interface with the compression garment and increase movement of fluid away from the wound site.

A foam laminate dressing includes a first distinct hydrophobic reticulated foam layer and an underlying second distinct hydrophilic layer bonded to the first layer and of substantially same length and width as the first distinct hydrophobic reticulated foam layer.

Dressings for tissue treatment with negative pressure and methods of assembling the dressings for tissue treatment with negative pressure are disclosed. A method of assembling a dressing, which may comprise at least three layers assembled in a stacked relationship, may comprise providing an assembly station having at least one retaining pin, placing a first layer on the assembly station, placing a second layer on the assembly station, and bonding the second layer to the first layer. The first layer may comprise a plurality of apertures, at least some of which may be engaged by the retaining pins, and the second layer may comprise fluid restrictions and alignment areas for engaging with the retaining pins so that the fluid restrictions may be aligned with the apertures of the third layer.

Disclosed embodiments relate to apparatuses for wound treatment. In certain embodiments, a negative pressure wound therapy apparatus includes one or more electronic components configured to be incorporated into layers of the wound dressing or integrated on top of the wound dressing. In some embodiments, a negative pressure source is incorporated into the wound dressing. The negative pressure source can be sealed between two moisture vapor permeable cover layers or enclosed in a moisture vapor permeable pouch, and may be received in a recess of an absorbent layer or spacer layer of a wound dressing apparatus.

The invention herein relates to a wound dressing product, combining a hydrophobic fabric, which is to be placed towards the wound, and is capable of binding unwanted microorganisms, and a moisture carrying matrix such as a gel or a foam. The product of the invention is ideal for treatment of drier wounds. It protects the wound and reduces the number of pathogenic microorganisms, without using antimicrobial substances and at the same time adds or traps moisture to the wound both supporting the hydrophobic functioning of the pad and healing in general by keeping the wound moist.

A method for dressing a wound is provided including providing a wound dressing pad of hydrophobic fabric that is treated to bind microorganisms; placing the hydrophobic fabric so that it faces the wound; and applying negative pressure therapy to the wound dressing so that microorganisms in the wound surface adhere to the dressing through hydrophobic interaction. The negative pressure therapy may be alternated with hyperbaric oxygen treatments of the wound dressing.

A multi-layer wound dressing includes a base layer with a circumscribing web of material defining a central opening of sufficient size to expose a wound area. An intermediate layer is the bandage layer that is placed over the opening in the base layer. An outer cover layer located above and over the bandage layer makes a sealing connection with the base layer and totally covers the intermediate bandage layer, providing sealing for the wound area and easy and repeated replacement of the bandage layer.
