As for the operational verification device, the dummy itself component is kept same as the cylinder component in the chemicals feeder, the dummy slide component same as the piston component is slid is moved in the chemicals feeder. This way when the chemicals feeder which keeps the dummy itself component making slide making move the dummy slide component when the liquid medicine is filled with the liquid medicine syringe, dummy resistant mechanism generates the movement resistance which is equal. Because of this, it is possible to operate the chemicals feeder same as the case where really the liquid medicine is filled to the subject. Because of this, before really filling the liquid medicine to the subject, the operational verification device which can verify the operation of the chemicals feeder precisely is offered.動作確認装置は、ダミー本体部材がシリンダ部材と同様に薬液注入装置に保持され、ダミースライド部材がピストン部材と同様に薬液注入装置にスライド移動される。このようにダミー本体部材を保持した薬液注入装置がダミースライド部材をスライド移動させるときに薬液シリンジで薬液が注入されるときと同等な移動抵抗をダミー抵抗機構が発生させる。このため、実際に被験者に薬液を注入する場合と同様に薬液注入装置を動作させることができる。これにより、実際に被験者に薬液を注入する以前に、薬液注入装置の動作を的確に確認することができる動作確認装置を提供する。
