Embodiment 1

[0048] Example 1: The core layer is OASIS impregnated with thinwood derived honey

[0049] OASIS by Technical Absorbents as described in PCT / GB2009 / 001407 The manufacture of the polymer involves polymerization in water, followed by extrusion of the aqueous polymer solution in a stream of hot air to dry and solidify the polymer, thereby producing insoluble polymer fibers. An extremely high conversion of raw material to polymer is achieved. Moisture may be added to the fibers to aid in processing, and the fibers are precision cut into a series of fiber cut lengths. OASIS superabsorbent technology can also be used to produce filament yarns (OASIS-FIL) and polymer solutions (OASIS-PS), either of which can be used in the present invention. Typically, when in sheet form, the thickness of the SAF layer is 0.25mm-10mm; 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm or 10mm thick. Preferably, the sheet thickness is less than 5mm, 4mm or 3mm, more preferably less than...

example 2

[0056] Example 2: The core layer is impregnated with honey derived from Thinmus genus and has Silon TM Coated OASIS

[0057] A core layer of OASISSAF was prepared and impregnated with Thinia derived honey.

[0058] The membrane overlay was prepared by BioMedSciences, and then the Silon TM The layer is rolled onto at least one surface of the honey-impregnated OASIS SAF core layer described above and applied to make the wound dressing roll of the present invention. Silon TM is an example of a combination product that includes a blend of silicone and polytetrafluoroethylene (PTFE), also known as Teflon TM . The wound dressing is then fenestrated by feeding the dressing through a cutting tool, which cuts through the Silon TM layer and partially cut the core OASISSAF layer to come. It should be understood that other methods of perforating the film layer would also be possible, such as perforating the adventitia layer by passing the dressing through a needling method that pr...

Abstract

The present invention relates to an impregnated wound dressing having an outer membrane overlay layer and to a method of production thereof. In particular the dressing comprises a core layer that has been impregnated with a wound healing agent, such as honey, and an outer membrane overlay layer.

Description

field of invention [0001] The present invention relates to an impregnated wound dressing with an adventitial covering and a method for its production. In particular, the dressing comprises a core impregnated with a wound healing agent, such as honey, and an outer membrane covering. Background technique [0002] Wounds affect the lives of many people. Some people suffer from non-healing wounds such as ulcers, infected wounds, inflamed wounds, etc. Wound dressings are needed to prevent further infection of such wounds. For some wounds that drain (exude) moisture or fluid, the wound dressing needs to be absorbent to contain the exudate while the wound dressing is in place. [0003] Wound dressings are often impregnated or coated with agents that promote wound healing or reduce the chance of infection. Such agents include but are not limited to silver products, antibacterial products such as antibiotics or honey or honey extracts or anti-inflammatory drugs or products. [0...
