Abstract
A wound dressing including a nonwoven absorbent layer including a layer of fabric comprising gel-forming fibers. The absorbent layer is gathered in a longitudinal direction by stitching through the layer of fabric using one or more resilient threads or yarns and an inelastic thread or yarn. The resilient and inelastic threads or yarns gather the layer of fabric so that the layer of fabric in use is configured to maintain close conformability with a wound during movement, and to elongate by 35% to 85% and then recover.
Claims19
A wound dressing comprising a nonwoven absorbent layer comprising a layer of fabric comprising gel-forming fibers, the absorbent layer being gathered in a longitudinal direction by stitching through the layer of fabric using one or more resilient threads or yarns and an inelastic thread or yarn, wherein the resilient and inelastic threads or yarns extend at least primarily in the longitudinal direction, and wherein the resilient and inelastic threads or yarns gather the layer of fabric so that the layer of fabric in use is configured to:
- (a) maintain close conformability with a wound during movement;
- and
- (b) elongate by 35% to 85% and then recover.
A wound dressing, comprising:
- a nonwoven absorbent layer comprising a layer of fabric comprising gel-forming fibers;
- and
- stitching that extends through the absorbent layer and that gathers the absorbent layer in a longitudinal direction, wherein the stitching comprises:
- a resilient thread or yarn extending at least primarily in the longitudinal direction;
- and
- an inelastic thread or yarn extending at least primarily in the longitudinal direction;
- wherein the stitching gathers the layer of fabric such that the layer of fabric is configured to:
- maintain close conformability with a wound during movement;
- and
- elongate from an initial length by 35% to 85% and to thereafter recover to the initial length.
