This disclosure relates to a wound care device which contains capillary force one-way pumps that are capable of transporting fluid, such as wound exudate, away from a wound site to the opposite side of the wound care device, which functions as a segregated fluid reservoir. This fluid transport mechanism generally aids in reducing wound maceration by removing excess wound fluid and the protease enzymes and infectious bacteria contained within the wound fluid. The wound care device performs this function, often times for multiple days, without the loss of the physical integrity of the wound care device. In addition to providing a uni-directional fluid transport mechanism, the wound care device contains a perforated adhesive layer.

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.

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.

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 medical device including a plasma-treated porous substrate that is functionalized to provide a hydrophilic surface, and a process for preparing such a medical device, are disclosed. The method includes plasma treating at least a portion of a surface of a porous substrate with a gas species selected from oxygen, nitrogen, argon, and combination thereof. The gas species is configured to functionalize the surface of the medical device and form a hydrophilic surface.
