Abstract
An apparatus for treating a wound can include a wound dressing, a vacuum pump configured to apply negative pressure to the dressing, and a fluid offtake tube configured to provide fluid communication between the pump and the dressing. The dressing can include a backing layer, a boss mounted to the backing layer at an opening in the backing layer, a foam layer on a proximal side of the backing layer, an adhesive on a periphery of the backing layer, and a membrane layer having a plurality of apertures configured to contact the wound. The foam layer can be in direct contact with the membrane layer, and can be configured to be simultaneously applied over the wound together with the backing layer. The adhesive can be configured to attach the backing layer to skin around the wound. The periphery of the backing layer can extend beyond and surround the membrane layer.
