Problems solved by technology

[0007] Clearly, this degradation is undesirable for wound dressings, since the collapse of the gel results in less fluid being retained by the wound dressing, which could potentially lead to wound soaking as the patient's wound and skin are exposed to the effects of gel degradation. fluid that seeps from it and fluid that seeps from the body

[0070] method

[0071] The wound dressing composition according to the invention can be prepared according to the following steps:

[0072] 1. Carding chitosan fibers (which may or may not contain antimicrobial agents as required) into non-woven fabrics (50gsm~300gsm);

[0073] 2. Preparation of lactic acid, SDS, A solution of poloxamer and a solvent (eg isopropanol) (Solution SLP);

[0074] 3. Coating the solution SLP onto the chitosan non-woven fabric using a dipping bath, spray system, etc. and drying; and

[0075] 4. The non-woven fabric is then cut and packaged, and can be sterilized using gamma radiation or by treating the non-woven fabric with ethylene oxide, the latter being preferred.

Abstract

The present invention relates to a wound dressing composition that is capable of gelling upon contact with a fluid derived from a human or animal body, and which is able to maintain the integrity of the gel for a period of time that is longer than about 24 hours.

Description

technical field [0001] The present invention relates to a wound dressing composition capable of gelling upon contact with fluid from the human or animal body and capable of maintaining the integrity of the gel for a period of greater than about 24 hours. Background technique [0002] Wound dressing materials for the treatment of wounds or other openings in or on a human or animal body at a physiological target site exuding blood and / or other bodily fluids have been known for some time. These wound dressing materials function to absorb blood and / or other bodily fluids and also prevent their escape from the body. Wound dressing materials for the above uses are described eg in WO2010031995 by MedTrade Products Ltd and are commercially available. [0003] Exudate management is of course very important and critical during wound care and surgical procedures. The purpose of exudate control is essentially to provide a moist wound environment at the wound bed and minimize the risk ...
