Medical protruded pads or dressings for wound care including use with orthopedic and prosthetic devices

摘要

Methods and devices for dressing a wound are disclosed. One such dressing includes a layer of spaced protrusions, each protrusion shaped to receive medication for treating a wound and a plurality of holes defined in the layer, the holes configured to allow evaporation of exudate from the wound. Another such dressing includes multiple layers, each layer sandwiched over the next and including spaced protrusions, with alternate layers comprising absorptive materials. The alternate layers of absorptive materials can communicate via holes in the non-absorptive layers to allow exudate to travel from between the absorptive layers and away from the wound.

主权项

1. A perforated wound dressing, comprising:
a first layer including a first set of spaced protrusions, each protrusion comprising an underside configured to face a wound and shaped to receive medication for treating the wound; a second layer overlying and directly adjacent to the first layer, including a second set of spaced protrusions, the second set of spaced protrusions being of similar shape to and aligned with the first set of spaced protrusions and wherein the second layer is harder than the first layer such that the second set of spaced protrusions better withstand compression; and a plurality of cylindrical holes defined through the first layer and the second layer, the holes configured to allow evaporation of exudate from the wound to pass through the perforated wound dressing in a direction substantially perpendicular to the wound's surface.
