Abstract
A wound dressing for a wound is disclosed. The wound dressing includes an absorbent pad. The wound dressing further includes a cover layer attached to the absorbent pad. The cover layer further includes at least a portion of a channel wall. The wound dressing further includes a channel defined by the channel wall. The channel surrounds the absorbent pad and is spaced apart from the absorbent pad. The channel is continuous and fluidly isolated from the absorbent pad. The channel is configured to receive a negative pressure. The wound dressing further includes a manifold member disposed within the channel. The manifold member at least partially engages the channel wall. The manifold member is collapsible in response to the negative pressure applied to the channel.
