Figure 18.1 is a picture of a triage tag.
So far, triage is operated manually using paper triage tags, tallies, and radiophones.
However, manually obtaining the information about the state and the scale of the casualty
incident to publish to the masses or to utilize for decision making such as medical resource
procurements leads to failure, inaccuracy, and delay in the information transmission while
emergency personnel have priority over treatments for injuries, and causes inef?¬?ciency in
classi?¬?cation and transport of the injured people effectively, which is the essential goal of
emergency medical services.
In this chapter, we propose a triage system in which RFID tags, which are silicon chips
with their IDs, radio frequency functions, and some additional logic and memory [1,2], are
attached to triage tags. Most of the RFID tags are passive, which means the power is
supplied through radio frequency communication from external readers. Employed RFID
tags in this work are passive and have 1 kb of rewritable memories. Figure 18.2 is a picture
of an RFID tag we employed.
Embedding an RFID tag to a triage tag has the following advantages:
1. Terminal that the emergency personnel use can identify the injured person by the
unique ID value in each RFID tag.
2. Rewritable RFID tags provide the storage for the information of the injured person,
and the emergency personnel can obtain the information when they are in a place
where wireless communication is out of service, such as deep in a mountain or in
the underground.
