Abstract:
1. A chemical liquid injection system including: a liquid syringe having a piston member being inserted slidably into a cylinder member filled with a contrast medium, and a chemical liquid injector having a liquid injection mechanism for relatively moving the cylinder member and the piston member of the liquid syringe exchangeably mounted on the chemical liquid injector to inject the liquid into a patient; wherein said liquid syringe further comprises an RFID (Radio Frequency Identification) chip having various types of data, including data on a resistance to pressure and data for checking conditions, recorded thereon, the RFID chip being mounted on said liquid syringe, and said chemical liquid injector further comprises: an RFID reader for obtaining the various types of data recorded on the RFID chip; an injection control unit having operation control means configured to perform a predetermined operation in accordance with at least some of the various types of obtained data and a first data display means configured to display various types of data; an injection head formed separately from the injection control unit, at least the liquid injection mechanism being mounted on the injection head; and a second data display means configured to display various types of data, wherein the second display means is disposed at a position away from the injection control unit, wherein the operation control means comprises a data holding means configured to hold the data including the data on the resistance to pressure from said RFID chip, an injection control means configure to control the operation of the liquid injection mechanism in accordance with the data on the resistance to pressure held in the data holding means, a data storing means configured to store predetermined check conditions as data and a data collating means configured to collate the stored check conditions with the data for checking conditions obtained from said RFID chip so that a check alarm can be output based on the collation result, the second data display means is a touch panel which also receives an entry operation, and the chemical liquid injection system is configured to display at least some of the various types of data obtained from said RFID chip at least on the second display means, and to allow an operator adjusting the operation based on the data obtained from the RFID chip by using the touch panel.
