Abstract
A chemical solution injection system, wherein a RFID chip (230) is mounted on a chemical liquid syringe (200) in the state of being wrapped around the outer surface of the cylinder member (210) thereof. An amplification antenna (240) wrapped one turn around the outer surface of the cylinder member (210) is disposed at the front of the RFID chip (230) parallel with each other. Since the communication performance of the RFID chip is increased by the amplifying antenna, the RFID chip (230) of the chemical solution syringe (200) is allowed to satisfactorily communicate with the RFID reader (131) of injection head (110).
