Description
本実施形態に係る透析液取出装置は、血液浄化治療(血液透析治療)で使用される血液浄化装置に配設され、透析液を採取可能とされたものである。適用される血液浄化装置は、図1に示すように、ダイアライザ1(血液浄化器)に動脈側血液回路2及び静脈側血液回路3が接続された血液回路と、透析液導入ラインL1及び透析液排出ラインL2を有した透析装置本体Bとから主に構成されている。
まず、接続手段15の先端15cを外周壁部13の内部に挿入させる際、図6に示すように、当該接続手段15の採取口12に対する相対位置及び姿勢がずれている場合を想定する。この場合、接続手段15を図中左側に移動させると、図7に示すように、接続手段15の先端15cが採取口12の突端12aに達する前に、当該先端15cがテーパ部13dに当接することとなる。
本実施形態に係る透析液取出装置は、第1の実施形態と同様、図1で示す如き血液浄化装置の透析液導入ラインL1に接続されたもので、図11〜13に示すように、透析液導入ラインL1(液体の流路)に接続されて当該液体(透析液)を流通させ得る導入口9a及び導出口9bが形成されるとともに、その流通する液体を採取可能な採取口12が形成された透析液取出手段9と、該透析液取出手段9の採取口12に対して脱着可能とされ、当該採取口12を開閉し得る開閉手段としてのキャップ10と、透析液取出手段9に形成された円筒状の外周壁部13と、キャップ10を取り外した状態の採取口12と接続可能な接続手段15とを具備したものである。なお、第1の実施形態と同様の構成部品には、同一の符号を付し、それらの詳細な説明を省略する。
