Claims (4)
- 患者に混合薬液を注入する際に用いられるミキシングデバイスであって、前記混合薬液が流出する流出口と、前記流出口に向かって連続的に狭窄している空間を有する狭窄室と、旋回流生成室とを有するミキシングデバイスと、
重力方向において前記流出口が前記旋回流生成室より下方に位置し、且つ前記旋回流生成室及び前記狭窄室の中心軸線が前記重力方向に平行となるか又は前記重力方向に傾くように、前記ミキシングデバイスが固定される固定部材と、
前記中心軸線と平行な方向に延在し、前記患者に注入される造影剤を導入する第1薬液導入管路と、
前記旋回流生成室内において前記旋回流生成室の前記中心軸線を中心とする円周の接線方向に延在し、前記造影剤の比重より小さい比重を有し且つ前記患者に注入される生理食塩水を導入して、前記旋回流生成室内に前記中心軸線まわりの前記生理食塩水の旋回流を生成する第2薬液導入管路と、を備える薬液注入システムであって、
前記狭窄室は、前記空間内に前記造影剤と前記生理食塩水とが案内されることにより、前記生理食塩水の旋回流に前記造影剤が衝突し、前記造影剤と前記生理食塩水との前記混合薬液を前記流出口から流出する薬液注入システム。 - 前記造影剤が充填された第1シリンジ及び前記生理食塩水が充填された第2シリンジが装着されるヘッドと、前記ヘッドに接続されたコントローラーとを有する薬液注入装置をさらに備え、
前記固定部材は、前記薬液注入装置、又は前記患者と前記薬液注入装置との間に置かれる中継台である、請求項1に記載の薬液注入システム。 - 前記ミキシングデバイスは、前記造影剤を前記旋回流生成室に導入するための第1流入口と、前記生理食塩水を前記旋回流生成室に導入するための第2流入口とを備える、請求項1または2に記載の薬液注入システム。
- 前記第1薬液導入管路は、前記旋回流生成室の内径よりも細くかつ前記中心軸線と同軸の方向に延在し、前記旋回流生成室内で拡散するように前記造影剤を導入する、請求項1から3のいずれか1項に記載の薬液注入システム。
