Abstract
A wound dressing includes a hydrophilic foam layer, a drape layer, superabsorbent projections, and printed indicators. The hydrophilic foam layer is configured to engage a wound bed and has a first side and a second side, the second side configured to face the wound bed. The drape layer has a first side and a second side, the second side configured to face the first side of the hydrophilic foam layer. The plurality of non-contiguous superabsorbent projections are fixed to and extend from the first side of the hydrophilic foam layer towards the second side of the drape layer. The one or more non-contiguous printed indicators surround one or more of the plurality of superabsorbent projections.
Claims18
A method of making a wound dressing comprising:
- providing a hydrophilic foam layer configured to engage a wound bed, and having a first side and a second side, the second side configured to face the wound bed;
- preparing and applying a slurry comprising a superabsorbent material onto the first side of the hydrophilic foam layer in the form of a plurality of non-contiguous deposits;
- printing one or more non-contiguous indicators onto the first side of the hydrophilic foam layer, such that the indicators surround one or more of the plurality of deposits;
- and
- placing a drape layer, having a first side and a second side, atop the hydrophilic foam layer.
A method of treating a wound, comprising:
- providing a dressing configured to cover the wound, the dressing comprising a hydrophilic foam layer having a plurality of non-contiguous superabsorbent deposits and one or more non-contiguous printed indicators surrounding a corresponding one or more of the superabsorbent deposits;
- observing, on the dressing, an amount of swelling of the superabsorbent deposits in response to the absorption of exudate from the wound;
- and
- replacing the dressing when edges of the swollen superabsorbent deposits approach the printed indicators within a predetermined range.
