Abstract
(EN)
Disclosed embodiments relate to apparatuses and methods for wound treatment. In certain embodiments, a wound treatment apparatus can comprise a wound dressing configured to be positioned over a wound site. The wound dressing can comprise an absorbent layer for absorbing wound exudate. The absorbent layer can comprise a superabsorbent material, wherein the superabsorbent material is positioned at one or more target areas of the absorbent layer. A backing layer can be provided over the absorbent layer and comprising at least one orifice.
