主权项

1. A wound treatment apparatus for treatment of a wound site comprising:
a backing layer having an upper surface and a lower surface and defining a perimeter configured to be positioned over skin surrounding a wound site, wherein the backing layer is configured to maintain negative pressure over the wound site; a first portion underneath the backing layer having a first layer structure comprising at least one material layer configured to transmit negative pressure to the wound site; and a bridging portion underneath the backing layer having a second layer structure comprising at least one material layer configured to transmit negative pressure from the first portion through the bridging portion, wherein the second layer structure of the bridging portion is different than the first layer structure of the first portion.
