Abstract
An apparatus for promoting the healing of an exuding wound includes a cover layer for positioning over a wound to define a reservoir over the wound. An exudate conduit having a fibrous core includes a plurality of fibers communicates with the reservoir for wicking fluids away from the wound.
Claims16
An apparatus to promote the healing of an exuding wound comprising:
- a cover layer for positioning over a wound to define a reservoir over the wound;
- and
- an exudate conduit including a fibrous core having a plurality of fibers communicating with the reservoir for wicking fluids away from the wound, wherein the fibrous core includes an inner bundle of fibers and an outer bundle of fibers, and
- wherein the inner bundle comprises hydrophobic fibers for discouraging fluid absorption and the outer bundle comprises hydrophilic fibers for promoting fluid absorption.

A method of bridging a wound comprising the steps of:
- applying a wound dressing over a wound;
- fluidly connecting an exudate conduit having a fibrous core to the wound dressing;
- extending the exudate conduit into a second reservoir that incorporates a vacuum port;
- and
- connecting the second reservoir to a vacuum source via the vacuum port thereby connecting the vacuum source with the first reservoir via the exudate conduit.
2 more elements
A composite wound dressing apparatus comprising:
- a cover layer for defining a reservoir over a wound in which a negative pressure may be maintained by forming a substantially fluid-tight seal around the wound, the cover layer including an aperture therein through which fluids may be extracted from the reservoir;
- an elongate wick having a first end and a second end, the first end in fluid communication with the reservoir through the aperture in the cover layer, the second end disposed remotely with respect to the aperture in the cover layer, the elongate wick adapted for longitudinal transport of fluids therethrough;
- a flexible wick cover extending over the elongate wick and having a first end and a second end, the first end configured for forming a substantially fluid tight seal over the aperture in the cover layer, the second end including an aperture therein through which fluids may be extracted from the elongate wick;
- and
- a fluid port coupled to the wick cover and in fluid communication with the second end of the elongate wick through the aperture in the wick cover, the fluid port configured to receive a fluid conduit.
2 more elements
A composite bridge dressing and delivery apparatus comprising:
- a wick cover having a lower surface and an upper surface, the lower surface at least partially coated with a pressure sensitive adhesive such that the wick cover may form a fluid tight seal with the skin of a patient;
- an elongate wick adhered to the lower surface of the wick cover, the elongate wick configured for longitudinal transport of fluids therethrough;
- and
- a backing layer adhered to the lower surface of the wick cover in a releasable manner such that the elongate wick is interposed between the wick cover and the backing layer.
