Claim 17:
18. A wound dressing for a plurality of wounds, comprising:
a chromic material responsive to at least one stimuli; and
a plurality of individual liquid-expandable articles, each of the plurality of individual liquid-expandable articles directly connected to each other at each of opposite ends, but longitudinally separable from one another at their opposite ends, defining a continuous elongated member expandable along its entire circumference for inserting the chromic material into a first wound and a second wound,
wherein a portion of the individual liquid-expandable articles of the continuous elongated member with a portion of the chromic material directly thereon is configured to be received and retained inside and in direct contact with the first wound and another portion of the individual liquid-expandable articles of the continuous elongated member, still connected to the portion of the elongated member retained inside the first wound, with another portion of chromic material directly thereon, is sized upon separation from the portion of individual liquid-expandable articles retained inside the first wound to be received and retained inside and in direct contact with the second wound, wherein each of individual liquid-expandable articles retained inside the first and second wounds releases stored mechanical energy at their ends directly connected to one another such that the liquid-expandable articles then separate from one another at their ends and mechanically expand into expanded articles upon contact with liquid inside the first and second wounds,
and wherein in response to the chromic material receiving the at least one stimuli the chromic material provides a first color change on the expanded articles occurring inside the first wound and a second color change on the expanded articles occurring inside the second wound, wherein the first and second color changes are different evidencing how long the expanded articles have been within the first and second wounds, respectively.
