A wound dressing comprising an absorbent layer, the absorbent layer being gathered in a longitudinal direction by one or more resilient yarns.
Claims8
A wound dressing comprising a nonwoven absorbent layer, the absorbent layer comprising two or more layers of fabric, wherein the two or more layers of fabric comprise gel-forming fibers, are layered together to substantially overlap and are gathered in a longitudinal direction by stitching through the two or more layers of fabric using one or more resilient threads or yarns and an inelastic thread or yarn, wherein the resilient and inelastic threads or yarns gather the two or more layers of fabric so that the two or more layers of fabric in use are configured to;
- (a) maintain close conformability with a wound during movement and
- (b) elongate by 35% to 85% and then recover.
A method of manufacturing a wound dressing for use on post-surgical wounds characterized in that the method comprises the steps of:
- (i) forming a nonwoven absorbent layer comprising two or more layers of fabric, wherein the two or more layers of fabric comprise gel forming fibers and are layered together to substantially overlap;
- (ii) gathering the two or more layers of fabric by stitching through the two or more layers of fabric with a resilient thread or yarn and an inelastic thread or yarn, wherein the resilient and inelastic threads or yarns gather the two or more layers of fabric so that the two or more layers of fabric in use are configured to:
- (a) maintain close conformability with a wound during movement, and
- (b) elongate by 35% to 85% and then recover;
- (iii) overlying the absorbent layer with an adhesive layer on a surface furthest from the wound in use and extending beyond the periphery of the absorbent layer so as to adhere the dressing to the skin.
