Claims (5)
- 医療用透視撮像装置と共に使用され、撮像される被験者に薬液を注入する注入装置において、
前記注入装置は、シリンダとシリンジピストンを備えた複数のシリンジを保持して、それぞれ独立して、前記シリンダに対して前記シリンジピストンを相対移動させる複数のピストン駆動機構と、このピストン駆動機構を制御する制御機構と、トリガー信号を発生させるトリガースイッチとを備え、
前記制御機構は、薬液注入が複数の段階で行われるように設定が可能であり、設定された条件に従って進行中の注入段階が完了する前に、前記トリガー信号を検知したときに、進行中の段階を停止して、異なる段階に移行する制御を行うことを特徴とする注入装置。 - 前記制御機構は、注入が開始される前に、各注入段階の条件が設定される手段を有することを特徴とする請求項1記載の注入装置。
- 前記各注入段階の条件は、少なくとも、複数のピストン駆動機構のうちで駆動されるピストン駆動機構の特定と、注入の終点および注入期間内の注入速度のパターン情報を含むことを特徴とする請求項2記載の注入装置。
- 前記制御装置が、前記トリガー信号を検知したとき、予め設定された段階の順序に従い、進行中の注入段階から次の注入段階への切り替えを行うことを特徴とする請求項1〜3のいずれかに記載の注入装置。
- 前記注入装置は、造影剤を収容するシリンジと生理食塩水を収容するシリンジの2つを搭載可能であることを特徴とする請求項1〜4記載の注入装置。
