DRESSING WITH FLUID ACQUISITION AND DISTRIBUTION CHARACTERISTICS
Systems, methods, and apparatuses for treating a tissue site are described. In some embodiments, the system may include a pouch having an upstream layer, a downstream layer, and an absorbent member enclosed between the upstream layer and the downstream layer. The upstream layer and the downstream layer may each include a hydrophobic side and a hydrophilic side. The hydrophilic side of both the upstream layer and the downstream layer may be positioned facing the absorbent member. The hydrophobic side of both the upstream layer and the downstream layer may form a portion of an exterior surface of the pouch such that fluid incident on the pouch is distributed laterally along the exterior surface of the pouch before being absorbed by the absorbent member.
Vacuum wound therapy wound dressing with variable performance zones
A dressing for an open wound includes a cover layer dimensioned for positioning relative to a wound bed. The cover layer permits an evacuation of the space around the wound bed such that a sub-atmospheric pressure may be established to stimulate healing and facilitate the removal of fluid from the wound. Multiple performance zones in the cover layer allow the wound dressing to remain in position through repeated cycles of evacuation without placing undue strain on the wound bed. An outer peripheral zone may include a high peel-strength adhesive while an intermediate zone may include a shear resistant adhesive. A central zone may be devoid of any coating to maximize moisture transmission through cover layer.
Cranial cap dressing
A cranial cap dressing for dressing a craniotomy wound comprising a breathable elastic outer layer sized to fit snuggly on a human head of a patient and an absorbent inner layer attached to the breathable elastic outer layer.
Liquid-permeable primary dressing with a silicone coating
The present invention relates to a fluid-permeable primary dressing in strip form, having pores, perforations or honeycomb lattices, which enable the passage of fluid, further having a coating of a material comprising silicone.
Apparatuses and methods for minimizing wound dehiscence, scar spread, and/or the like
Apparatuses for minimizing scar spread and reducing risk of wound dehiscence and related methods. Some of the apparatuses include a flexible first strip and a flexible second strip, the first and second strips configured to be coupled to a patient's back on opposing sides of a wound and a substantially inelastic and flexible layer of material configured to be directly coupled to the first and second strips with the layer in tension to resist separation of the first and second strips, where the layer is configured to be removably coupled to at least one of the first and second strips. In some of the apparatuses, the layer is configured to be removably coupled to each of the first and second strips. In some of the apparatuses, the layer is non-removably coupled to and/or is unitary with at least one of the first and second strips.

Wound Dressings Containing One or More Layers
Single layered nonwoven wound dressings containing (1) about 5% by weight to about 95% by weight (e.g., 5% to 95%) non-scoured, non-bleached greige cotton fibers, (2) about 5% by weight to about 95% by weight (e.g., 5% to 95%) bleached cotton fibers, and (3) about 5% by weight to about 60% by weight (e.g., 5% to 60%) hydrophobic fibers (e.g., polypropylene, nylon); all percentages adding up to 100 wt %. Also, multi-layered nonwoven wound dressings, containing (1) at least one inner layer containing (a) about 50% by weight to about 95% by weight (e.g., 50% to 95) non-scoured, non-bleached greige cotton fibers and (b) about 5% by weight to about 50% by weight (e.g., 5% to 50%) hydrophobic fibers, all percentages adding up to 100 wt %, and (2) at least one outer layer containing (a) about 5% by weight to about 95% by weight (e.g., 5% to 95%) non-scoured, non-bleached greige cotton fibers, (b) about 5% by weight to about 95% by weight (e.g., 5% to 95%) bleached cotton fibers, and (c) about 5% by weight to about 60% by weight (e.g., 5% to 60%) hydrophobic fibers (e.g., polypropylene, nylon); all percentages adding up to 100 wt %.
TUBULAR BANDAGE
Tubular bandage, in particular a finger or toe bandage which is formed as a tube comprising an outer layer which is connected to an inner layer, and wherein the outer layer has a diameter and an elasticity such that the bandage can be clamped adhesive-free around the body part to be treated, in the particular, said finger or said toe, and wherein the inner layer is made of an elastic wound-protective material, wherein said outer layer is made of an air-permeable and water-repellent material, and wherein, at the open endings, said outer layer extends in the longitudinal direction over the inner layer over a distance of more than 0.5 mm, such that the outer layer touches the body part to be treated, in particular a finger or toe, with its endings when applied.
WOUND CARE DEVICE HAVING FLUID TRANSFER AND ADHESIVE PROPERTIES
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.
Self-Fusing Low Density Silicone
An adhesive free self-fusing material being either of open or closed cell polymer (silicone) based material that can be used to create a permanent elastic band for compression and support dressings. The proprietary polymer material upon contact with itself, initiates a room temperature reaction of self-vulcanization with the contact surfaces of itself. This eliminates the need for any adhesives which some patients experience negative reactions. In an example embodiment, the material comprises Vinyl stopped polydimethyl siloxane, amorphous silica, and dimethylpolysiloxane.
