Abstract

Disclosed embodiments relate to wound therapy apparatuses and methods for use in negative pressure wound therapy (NPWT). Such wound therapy apparatuses and methods may reduce maceration during NPWT. The wound therapy apparatus may include a porous hydrophobic layer surrounded by a hydrophilic ring. The hydrophilic ring may serve to prevent passage of liquid while negative pressure is applied to the wound, but allow liquid passage to an absorbent ring when negative pressure is no longer applied. A transmission layer may also be included, underlying the absorbent layer.
