前記ポンプは、前記輸液流路上に設けられた輸液ポンプであり、
前記制御部は、プライミング時に前記プライミングポンプを正転作動させる一方、前記検知器が気泡を検知した場合に、前記プライミングポンプを停止させて前記輸液ポンプを作動させることにより前記輸液貯留部から前記検知器を経由して前記洗浄液貯留部へと前記輸液を供給する、請求項1に記載の血液浄化装置。 - 前記洗浄流路は、患者脱血部と前記血液浄化器を接続する動脈ラインである、請求項8から13の何れか一項に記載の血液浄化装置。
- 前記洗浄流路は、患者脱血部と前記血液浄化器を接続する動脈ラインに配置されたプライミングラインを有する、請求項8から13の何れか一項に記載の血液浄化装置。
- 前記制御部は、前記検知器が気泡を検知した場合に、前記ポンプを所定量作動させた後に警報を発生させる、請求項1から15の何れか一項に記載の血液浄化装置。
- 前記制御部は、前記検知器が気泡を検知した場合に、警報を発生させるとともに前記ポンプを停止させ、警報解除後に前記ポンプを作動させる、請求項1から15の何れか一項に記載の血液浄化装置。
- 血液浄化器と、洗浄液が貯留された洗浄液貯留部と、前記血液浄化器と前記洗浄液貯留部とを接続する洗浄流路と、前記洗浄流路上に設けられ気泡を検知する検知器と、前記血液浄化器に連通し前記洗浄液を排出する排出流路と、輸液を貯留する輸液貯留部と、前記検知器と前記輸液貯留部との間の流路上に設けられたポンプと、を備える血液浄化装置のプライミング方法であって、
前記検知器がプライミング中に気泡を検知した場合に、前記輸液貯留部から前記検知器を経由して前記洗浄液貯留部へと前記輸液を供給するように前記ポンプを作動させる工程を含む、血液浄化装置のプライミング方法。
