Abstract
A selectively transparent wound therapy dressing, system, and method of use are provided. The dressing may include conformable foam and drape layers, wherein the drape layer has a refractive index substantially within a range of a disclosing liquid. When the disclosing liquid is applied to the drape layer, the drape layer may switch from opaque to transparent. Subsequent evaporation of the disclosing liquid may return the drape layer to an opaque state. Some embodiments provide for paired use with a negative pressure source input device. The method of use provides selective visibility of a treatment site, and reduces the amount of time in which a patient views an acute or traumatic wound or injury.
