Abstract: The present invention relates to a bonded nonwoven fabric generally including absorbent staple fibres and having bonding stripes of relatively high fibre entanglement density extending along the fabric and into the fabric from at least one face thereof. A method of producing a bonded nonwoven fabric suitable for use as an absorbent layer in a wound dressing is also described.

Abstract: The present invention relates to wound dressings which are particularly useful (but not necessarily exclusively) on moderate to heavily exuding wounds comprising: an absorbent pad having a first major face comprised of absorbent material and configured for wound contact, and a second major face opposed to the first major face; and a backing layer bonded to the second major face of the pad; wherein the pad and the backing layer are sized such that the backing layer extends beyond the periphery of the pad, thereby defining a margin; wherein the margin of the backing layer is provided with a first adhesive for adhering the backing layer to skin; and wherein a layer of second, low trauma adhesive is provided on, and in direct contact with, the first major face of the pad for adhering the pad to a wound, said layer of second, low trauma adhesive being configured to allow passage of exudate from the wound to the absorbent pad.

Abstract: A computer-implemented method includes: obtaining input data comprising a plurality of data values, wherein each data value is associated with a time value; obtaining a plurality of threshold criteria; and (a) selecting, or generating, a dataset or a plurality of datasets that are different to one another from the input data, and determining whether each selected, or generated dataset meets a threshold criterion of the plurality of threshold criteria; and (b) causing each selected, or generated, dataset that meets the threshold criterion to be stored in memory in association with the threshold criterion, repeating (a) and (b) for each threshold criterion of the plurality of threshold criteria, thus causing a plurality of datasets to be stored in the memory, wherein each stored dataset meets a threshold criterion of the plurality of threshold criteria.

Abstract: An absorbent product intended particularly for use as a wound dressing comprises an admixture of carboxymethyl chitosan and chitosan wherein the chitosan incorporates at least one antimicrobial agent. Absorbency is provided by the carboxymethyl chitosan and antimicrobial properties by the antimicrobial agent incorporated in the chitosan.

Abstract: A wound dressing comprises: (i) a core of a non-woven layer comprising gelling fibres and having first and second major faces, (ii) a first layer of an absorbent foam positioned with one face adjacent to the first face of the non-woven layer, (iii) a second layer of an absorbent foam positioned with one face thereof adjacent to the second face of the non-woven layer, (iv) an open material positioned against that face of the first absorbent foam layer remote from the non-woven layer; and (v) an open material or a continuous semi-permeable film positioned against that face of the second absorbent layer remote from the non-woven layer. Layers (i)-(v) may be bonded together.

Abstract: A wound dressing comprises a wound contacting material incorporating a therapeutically effective amount of a particulate, water insoluble, inorganic silver salt containing at least 50% by weight (based on the weight of the salt) of silver for delivering silver to a wound. The preferred water-soluble, inorganic silver salt is sodium carbonate. The wound contacting material may comprise an alginate.
