Draining wound dressing

摘要

A wound dressing is made of multiple layers and includes a collection chamber that is in fluid communication with a drainage channel. When applied over a wound, the wound dressing provides protection for the wound while allowing air and fluids to evacuate from the wound through the collection chamber and out through the drainage channel. The wound dressing can include a valve that restricts air and fluids from entering the wound, which is beneficial for treating pneumothorax.

1. A dressing for treating a wound, the dressing comprising:
a base layer comprising a first aperture extending through the base layer; a first adhesive layer coupled to a first side of the base layer and comprising a second aperture extending through the first adhesive layer; a second adhesive layer coupled to a second side of the base layer and comprising a third aperture extending through the second adhesive layer; a channel layer comprising at least one member coupled to portions of the second adhesive layer; and a top layer coupled to at least portions of the second adhesive layer and apposed to the channel layer, wherein a channel is formed between the channel layer and the top layer, the channel extending from the third aperture to an edge of the second adhesive layer; wherein the first aperture, second aperture, and third aperture are generally aligned to form a collection chamber that is in fluid communication with the channel; wherein the top layer is configured to have a closed position relative to the channel layer, wherein the top layer is configured to collapse against the channel layer to form a generally fluid tight arrangement between the top layer and the channel layer.
