Embodiment Construction

[0131] Referring first to Figure 1(a), there is shown a schematic diagram 1 of lapping of a pattern for a warp knitted fabric. Laying diagrams are formed by a grid of points. Each dot represents needle 2 and threads 3 and 4 represent the path of the thread in the woven fabric. Each horizontal row of needles represents a course, ie a single stitch formation process. Each vertical column of needles involves a separate thread 3 (warp thread) each of which runs vertically up the column to form a closed loop 5 around each needle 2 . The laying diagram also includes a single weft thread 4 that moves horizontally across each path to interlock with closed loops 5 of warp threads 3 to form the fabric structure. The resulting fabric has a crochet stitch pattern.

[0132] Figure 1(b) is a schematic diagram of laying yarns showing an alternative construction for a warp knitted fabric formed with two needle warp yarns in a closed tricot (warp twill) stitch pattern. Each vertical column...

Abstract

Wound dressings, methods for their production and components for use therein. A knitted structure comprising a blend of gelling fibres and non-gelling fibres wherein the yarn comprises at least 50% w / w gelling fibres, a three-dimensional textile material comprising gelling fibres, and a yarn comprising a blend of gelling and non-gelling fibres which may be used in their production, the knitted structure and three-dimensional textile material beings suitable for use as wound dressings or as components of composite wound dressings. The wound dressings may be adapted for use in negative pressure wound therapy (NPWT). It has been found that the incorporation of gel-forming fibres provides a material which has a high absorbency, enabling good transfer of exudates away from a wound, which retains structural integrity, and which is non-adherent and easily removed from the wound.

Description

technical field [0001] The present invention relates to wound dressings. More particularly, the invention relates to a wound dressing comprising a thread formed of gelling fibers, especially a mixture of gelling and non-gelling fibers, and to such a thread. Background technique [0002] In order to meet different clinical needs, different types of wound dressings are required. However, common requirements for wound dressings are that they absorb exudate from the wound and retain sufficient structure so that they can be easily removed from the wound after use without tearing or rupturing. If the wound dressing cannot be completely removed from the wound, the patient will suffer additional pain. Additionally, if a wound dressing splits or ruptures upon removal, pieces of the dressing can remain in the wound, inhibiting healing. Especially for some wounds, such as pit wounds, it is necessary to remove all material when changing the wound dressing, as cases of giant cell fore...
