Embodiment Construction

[0074] The invention will now be described in more detail with reference to the accompanying drawings showing preferred embodiments of the invention.

[0075] As shown with reference to Figures 1a and 1b, the device of the invention may be a wound dressing comprising an absorbent element (1) covered on the distal surface (with respect to the wound) with a top layer (2), for example Permeable membrane through which moisture vapor can permeate. In the central part of the wound-facing surface of the absorbent element, the active agent is applied in a suitably defined area (3). Preferably, the area of ​​said region is about the size of a wound. This region may comprise multiple layers (not shown), for example comprising a blend of activator and gel-forming polymer. The gel-forming polymer provides controlled / delayed / slow release of the active agent when the device is applied to the wound site. The amount and concentration of the gel-forming polymeric species is selected to prov...

Abstract

An absorbent wound care device comprising an absorbent element and an active agent, said absorbent element having a proximal and a distal surface, wherein the active agent is positioned on the proximal surface of the absorbent element and wherein the active agent is positioned in a zone having an exact defined area covering a central portion of the absorbent element, and wherein said area of the zone covers only a portion of the proximal surface of the absorbent layer, and a method of preparing such device.

Description

technical field [0001] The present invention relates to a method of producing a wound care device comprising an absorbent element and an activator, and to such an oral care device, which wound care device is particularly suitable for the treatment of chronic wounds and burns. Background technique [0002] Chronic wounds typically affect persons over the age of 65 due to the underlying clinical complications typically associated with chronic wounds, such as venous and arterial insufficiency, diabetes and trauma, and bed sores from bed rest. In addition to the economic aspects of chronic wound care, patients are severely suffering the combined effects of infection, pain, and poor quality of life combined with greatly increased risk of amputation and premature death. [0003] Current treatment of chronic wounds and burns varies across the world, advanced wound healing devices based on passive bandages that facilitate moist wound healing and secretion control are the current sta...
