Chromism For Hemorrhage Control

机译:色度控制出血

摘要

A wound dressing having a chromic material responsive to at least one stimuli. In one or more embodiments, a plurality of individual liquid expandable articles introduce the chromatic material to the wound. The individual liquid-expandable articles release stored mechanical energy and mechanically expand into expanded articles upon contact with a liquid associated with the wound. In response to the chromic material receiving the at least one stimuli the chromic material provides a color change evidencing how long the expanded articles have been in contact with the wound and where the expanded articles are within the wound. In one or more embodiments, determinations may be made about removing the expanded articles from the wound based on the color of the chromic material.
