Abstract
A non-adhesive absorbent wound dressing (10) is suitable for application about a jointed limb. The wound dressing (10) has a first portion (20) adapted to conform to and wrap around an upper part of the limb, a second portion (30) adapted to conform to and wrap around a lower part of the limb, and a hinge portion (40) between said first portion (20) and said second portion (30), said hinge portion (40) in use lying adjacent to the joint of the limb. The wound dressing (10) also comprises a porous wound contact sheet (80) and a substantially liquid-impermeable backing sheet (90), the wound contact sheet (80) and the backing sheet (90) being bonded (50) together at their periphery and along lines that define a plurality of pockets (60) in both the first portion (20) and the second portion (30), the pockets (60) containing absorbent material (70).
Core Innovation
The invention provides a non-adhesive absorbent wound dressing for application about an ankle joint, with a first portion adapted to conform to and wrap around a lower leg and a second portion adapted to conform to and wrap around a foot portion corresponding to the lower leg. A hinge portion lies between the first portion and the second portion, and in use is positioned adjacent to a heel corresponding to the foot so that the dressing is usable during joint flexion.
The dressing includes a porous wound contact sheet and an opposite substantially liquid-impermeable backing sheet. The porous wound contact sheet and the backing sheet are bonded together at their periphery and along lines that define a plurality of pockets in both the first portion and the second portion, with the pockets located across substantially the entire surface of the wound contact sheet.
The pockets contain a superabsorbent material to absorb and retain exudate, and the hinge portion between the first and second portions comprises a bonded area extending across the dressing, from one point on a perimeter of the dressing to another. In this configuration, the pocketed wound-contact structure is maintained across the dressing surface while the hinge portion supports flexing about the ankle.
Claims Coverage
The document contains one independent claim. Claim 1 is directed to a hinge-connected non-adhesive absorbent wound dressing for an ankle joint area with pocketed superabsorbent absorption across substantially the entire wound-contact surface.
Hinge-connected non-adhesive dressing for an ankle joint area
A non-adhesive absorbent wound dressing for application about an ankle joint having a first portion adapted to conform to and wrap around a lower leg and a second portion adapted to conform to and wrap around a foot portion, with a hinge portion between the first and second portions, the hinge portion in use lying adjacent to a heel corresponding to the foot.
Porous wound contact sheet bonded to a substantially liquid-impermeable backing sheet forming multiple pockets
The dressing comprises a porous wound contact sheet and a substantially liquid-impermeable backing sheet opposite of the wound contact sheet, the wound contact sheet and the backing sheet being bonded together at their periphery and along lines that define a plurality of pockets in both the first portion and the second portion, the pockets being located across substantially the entire surface of the wound contact sheet.
Superabsorbent material contained in pockets across substantially the entire surface
The pockets contain a superabsorbent material and are located across substantially the entire surface of the wound contact sheet.
Hinge portion includes a bonded area extending across the dressing from perimeter point to perimeter point
The hinge portion between the first and second portions comprises a bonded area which extends across the dressing, from one point on a perimeter of the dressing to another.
Overall, the independent claim coverage centers on a hinge-adjacent ankle/foot dressing architecture combining a porous wound contact sheet and a substantially liquid-impermeable backing sheet, bonded to define multiple pockets across substantially the entire wound-contact surface, with the pockets containing a superabsorbent material.
