Abstract
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.
Claims20
A wound dressing, comprising:
- a chromic material responsive to at least one stimuli;
- and
- at least one article configured to introduce the chromatic material to the wound,
- wherein in response to the chromic material receiving the at least one stimuli the chromic material provides an indicator indicating the at least one article is at least partially in contact the wound.
A wound dressing, comprising:
- a chromic material responsive to at least one stimuli;
- and
- a plurality of individual liquid expandable articles for introducing the chromatic material to the wound,
- wherein the individual liquid-expandable articles release stored mechanical energy and mechanically expand into expanded articles upon contact with a liquid associated with the wound, and wherein 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.
A kit for dressing a wound, the kit comprising:
- a chromic material responsive to contact with the wound;
- at least one article configured to introduce the chromatic material to the wound;
- and
- information for measuring a color change of the chromic material as a result of the at least one article being in contact with the wound, wherein the information comprises at least one of the following:
- a plurality of colors corresponding to a plurality of time periods;
- and
- a plurality of colors corresponding to a plurality of temperatures,
- wherein, in response to measuring the color change with the information, a length of time may be determined as to how long the at least one article has been in contact with the wound.
