Furthermore adjustment of timing of start of scan of the CT device and the like is unnecessary and does not require troublesome job for inspection the system which it is possible, to set fill condition simply, is offered. As for control means of this system, the syringe (200) the liquid medicine quantity which has gone inside (the remaining amount) processing and the display which are calculated (51), the processing which decides chemical grouting speed as chemical grouting time it decides one of the candidacy times which are selected the button for selection in order to select one from midst of candidacy of the plural chemical grouting times which beforehand are decided (71a) by pushing processing and the button for that selection which are made to indicate, on the basis of with the particular chemical grouting time which are processed and is decided and the schedule injection rate below the aforementioned liquid medicine quantity which was calculated, and,The aforementioned piston drive (13) controlling, the description above is decided the processing which is made to fill at the chemical grouting speed which and, it does the aforementioned schedule injection rate.注入条件を簡単に設定することができ、しかもCT装置等のスキャン開始のタイミングの調整が不要で検査に煩雑な作業を要さないシステムを提供する。このシステムの制御手段は、シリンジ(200)内に入っている薬液量(残量)を算出する処理と、ディスプレイ(51)に、予め決められた複数の薬液注入時間の候補の中から1つを選択するための選択用ボタン(71a)を表示させる処理と、その選択用ボタンを押すことによって選択された候補時間の1つを、薬液注入時間として決定する処理と、決定された当該薬液注入時間と、算出された前記薬液量以下の予定注入量とに基づいて、薬液注入速度を決定する処理と、前記ピストン駆動機構(13)を制御して、前記予定注入量を前記決定された薬液注入速度で注入させる処理と、を行う。
