Embodiment Construction

[0050] figure 1 A cross-section through a wound dressing 100 according to an embodiment of the invention is shown. figure 2 A plan view from above the wound dressing 100 is shown, the line A-A indicates figure 1 The location of the cross section shown. will understand, figure 1 A generalized schematic view of the appliance 100 is shown. It will be appreciated that embodiments of the present invention are generally applicable in partial negative pressure (TNP) systems. In short, negative pressure wound therapy aids the closure and healing of many forms of "hard-to-heal" wounds by reducing tissue edema, promoting blood flow and granulation tissue formation, removing excess exudate, and may reduce bacterial growth (and thereby reduce the risk of infection). In addition, the treatment leaves the wound less disturbed, resulting in more rapid healing. The TNP system can also aid in the healing of surgical closure wounds by removing fluid and by helping to stabilize tissue opp...

Abstract

The methods and devices disclosed herein are used to dress wounds. The wound dressing includes a transmission layer having a first surface and another surface, the other surface being spaced apart from the first surface by a relaxed distance in a relaxed mode of operation. A plurality of spacer elements extend between the first surface and the other surface, and in the stressed mode of operation, the plurality of spacer elements can be positioned such that the first surface and the other surface are separated by a compressed distance less than Slack distance.

Description

technical field [0001] The present invention relates to methods and devices for providing protection to wound sites. In particular, but not exclusively, the present invention relates to wound dressings usable during topical negative pressure (TNP) therapy, wherein the wound dressing acts as a cushion to help prevent compressive forces or Shearing forces injure the healing wound. Background technique [0002] There is already a lot of available prior art relating to the provision of devices and methods of their use for applying topical negative pressure (TNP) therapy to wounds and other therapeutic procedures intended to enhance the effect of TNP therapy. Examples of such prior art include those listed and briefly described below. [0003] TNP therapy aids in wound closure and healing by reducing tissue edema, promoting blood flow, stimulating granulation tissue formation, removing excess exudate, and may reduce bacterial growth and thus wound infection. In addition, TNP t...
