摘要:
The wound dressing described herein can be used as a contact layer dressing. The wound dressing can be positioned between a wound bed and a secondary dressing. The wound dressing can include a layered construction. Each of the layers can include a bioresorbable sponge enclosed within a collagen-based film. The wound dressing can include a plurality of fluid channels that enable fluid flow from the wound bed toward the environment-face side of the wound dressing.

Die Erfindung betrifft einen Kompressionsverband umfassend eine erste Polsterschicht (1) und eine zweite Stützschicht (2), wobei die beiden Schichten (1,2) im ungedehnten Zustand mittels Nähwirkverfahren über einen elastischen Nähfaden miteinander verbunden sind und die Stichläge 1,5 bis 3 mm/U beträgt bei einer Nähfadenspannung von höchstens 4 cN.
摘要:
Disclosed herein is a multilayered wound dressing comprising a first layer; the first layer including channels that facilitate neovascularization of a wound; and a second layer in contact with the first layer, the second layer having the same or different chemical composition as the first layer; where the second layer comprises at least one surface that has a texture and the direction of the texture is operative to facilitate cell orientation and growth. A method includes forming a first layer of a polymeric material; forming a second layer of the same polymeric material as the first layer on the first layer; and forming a textured surface of the second layer of the same polymeric material as the first layer, the textured surface being operative to facilitate directional cell growth when used in a wound dressing, where the first layer and the second layer are formed using an additive manufacturing process.

The present invention relates to a wound dressing composition for use as or in a wound dressing and to methods of making the wound dressing composition. The wound dressing composition comprises wicking material, and superabsorbent material that is punched into the wicking material. The action of punching the superabsorbent material into the wicking material acts to significantly increase the rate of absorption of the combination materials.

Illustrative embodiments of a dressing for treating a tissue site may include a fluid transport layer, an offloading layer, and a liquid deflector. The offloading layer may be in fluid communication with the fluid transport layer, and the offloading layer may include a force offloading region and a target region. The liquid deflector may be positioned between the fluid transport layer and the offloading layer. The liquid deflector may be configured to deflect a liquid from the tissue site into contact with the target region of the offloading layer. The target region may be configured to expand for offloading forces at the tissue site. Other dressings, systems, and methods are disclosed.

A wound dressing system that includes a conformal cover and an infusion pump is provided. The cover includes a fluid port and an oxygen catalyst. The infusion pump is configured to deliver a bioactive liquid to the cover via the fluid port. The liquid includes an oxygen precursor. Upon combination, the oxygen catalyst and precursor react to form oxygen. A method of applying a wound dressing system including a bioactive powder, a bioactive liquid, and a conformal cover to a wound site is also provided. The method includes applying the powder to the wound site; securing the cover around the wound site, where the cover includes an oxygen catalyst and a fluid port; and delivering the bioactive liquid to at least an inner layer of the cover via the fluid port, where the bioactive liquid includes an oxygen precursor.

La présente invention a pour objet un matériau composite de remplissage de plaie comprenant une enveloppe renfermant un matériau ou un ensemble de matériaux formant des canaux d'écoulement de fluide, ladite enveloppe étant constituée d'un matériau non tissé formé d'un mélange de fibres superabsorbantes bicomposant et de fibres non absorbantes thermoliantes, lesdites fibres superabsorbantes bicomposant étant de type cœur/écorce, ledit cœur étant en polyacrylonitrile et l'écorce étant en polyacrylate..
摘要:
A wound dressing including a hydrophilic layer and a hydrophobic layer is described. The hydrophilic layer absorbs exudate from a wound and the hydrophobic layer absorbs the exudate from the hydrophilic layer and traps the exudate. Because the hydrophilic layer is used adjacent to the wound, the exudate is readily absorbed thereby reducing the risk of maceration and infection of the wound tissue by the exudate. The hydrophobic layer receives the absorbed exudate from the hydrophilic layer and traps the exudate through an interaction that in turn prevents lateral diffusion of the exudate through the bandage to healthy portions of the skin. The hydrophilic and hydrophobic layers are fabricated from polymer fibers that can be spun to include components that facilitate wound healing, such as poly(hexamethylene biguanide) and/or hyaluronic acid.

摘要:
Some arrangements disclosed herein relate to devices and methods for treating a wound, comprising applying negative pressure to the wound through a cover applied over a wound, monitoring the internal pressure in the wound, and controlling the closure of the wound by controlling the amount that a wound packing material positioned under the cover collapses within the wound based on the monitored internal pressure. The wound packing material collapse can be controlled to ensure that the monitored internal pressure does not exceed a threshold value. Additionally, some embodiments or arrangements disclosed herein relate to a visualization element to visualize a location of a wound surface. The visualization element can comprise a radiopaque member that is configured to be positioned on or adjacent to a surface of an open wound.
