The invention relates to a wound bed access device for providing access to a wound bed from outside a closed wound. The wound bed access device includes a self- sealing valve connector defining a flow path which is ordinarily closed and is opened when a complementary opening connector is connected to the self-sealing valve connector. The wound bed access device also includes a wound dressing interface, shaped and dimensioned to be closed within a wound dressing covering a wound. The self-sealing valve connector is connected to the wound dressing interface, with the flow path passing from the self-sealing valve connector through the wound dressing interface. In use, the self-sealing valve connector is positioned outside the wound dressing thereby providing access to the wound bed from outside the closed wound.
