Claim 0:
1. A wound dressing for a plurality of wounds, comprising:
a chromic material responsive to at least one stimuli; and
an elongated member configured to insert the chromic material into the wound, the elongated member defining a plurality of individual liquid-expandable articles,
each of the liquid-expandable articles directly connected to each other at each of opposite ends, but separable from one another at their opposite ends, to define a length of the elongated member,
and the elongated member expandable along its entire circumference,
a distal end of the elongated member configured to be partially received within the wound still connected with a portion of the plurality of the individual liquid-expandable articles of the elongated member remaining outside the wound sized for a second wound and such that another portion of the plurality of the individual liquid-expandable articles connected end to end directly to one another with at least a portion of the chromic material directly thereon is received and retained inside and in direct contact with the wound and also, once inside the wound, releases stored mechanical energy at their ends such that liquid-expandable articles then separate from one another at their opposite ends upon contact with liquid inside the wound and mechanically expand into expanded articles,
wherein in response to the portion of chromic material receiving the at least one stimuli, the portion of chromic material on each of the liquid-expandable articles changes on each of the liquid-expandable articles inside the wound to provide within the wound a plurality of indicators inside the wound, each of the plurality of indicators in the wound indicating that the other portion of the plurality of the individual liquid-expandable articles received and retained inside the wound is in contact with liquid inside the wound.
