Abstract:
Disclosed are hybrid wound dressings that include at least one front layer of a hydrophilic absorbent material and at least one layer behind the front layer that is made of an open-celled polymeric foam made from high internal phase emulsions (HIPEs). The hydrophilic absorbent material may be a natural polymeric material; a synthetic, non-foam polymer; or a material like glass microfiber. Each layer has a rate of fluid absorption and a capillary suction pressure (CSP) for a working fluid like blood plasma. The CSP increases from the front layer toward the layers behind the front layer, such that fluid is drawn away from a wound.

Claim (Index 12):
A wound dressing, comprising:\n a cover mesh having a first rate of fluid absorption for a working fluid; and a first layer of an absorbent hydrophilic material having a second rate of fluid absorption for the working fluid and exerting a second capillary suction pressure (CSP) in absorbing the working fluid; one or more intermediate layers of open-celled synthetic polymer foam, a first of the one or more intermediate layers of foam being adjacent to and in fluid communication with the first layer and ones of the one or more intermediate layers of foam behind the first intermediate layer of foam being adjacent to and in fluid communication with each other, each of the one or more intermediate layers of synthetic polymer foam having an individual CSP, each of the individual CSPs being greater than the second CSP and greater than the individual CSP of a prior intermediate layer of foam; and a rear layer of open-celled foam produced by polymerizing a high internal phase emulsion (HIPE) adjacent to and in fluid communication with a rearmost of the one or more intermediate layers of foam, the rear layer of foam being generally homogeneous in internal structure, having a third rate of fluid absorption for the working fluid, and exerting a third CSP in absorbing the working fluid, the third CSP being greater than the individual CSP of the rearmost of the one or more intermediate layers of foam.
