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.
Claims16
A wound therapy dressing comprising:
- a foam layer, and
- a drape layer comprising a material having a refractive index substantially within a range of 1.3 to 1.55.
-43. (canceled)
A method for wound therapy comprising:
- (i) applying to a treatment site a wound therapy system comprising:
- a conformable, transparent foam dressing layer;
- and
- a conformable, selectively-transparent drape layer configured to extend over and adhere the transparent foam dressing layer to a treatment site;
- (ii) applying a disclosing liquid with a refractive index within a range of the refractive index of the drape layer to the drape layer, wherein the selectively-transparent drape layer changes from a first, opaque state to a second, transparent state;
- (iii) observing the treatment site while the drape layer remains in the transparent state;
- and
- (iv) allowing the disclosing liquid to evaporate, whereby the drape layer returns to an opaque state.
