Description
図1に示すように、検査用血液容器1Aは、容器本体部2と、血液流入ポート5と、血液流出ポート6と、排気部7とを備える。
図3に示すように、検査用血液容器1Bは、前記構成のうち排気部7の管状通路11が、チューブ8で構成される細径の第1管状通路9と、この第1管状通路9に連通するように上方に突出した内部空間3の頂部の一部で構成された細径の第2管状通路10とからなる。第1管状通路9は、図1に示すようなチューブ8の一端8aが、内部空間3と連通するように融着または接着によって容器本体部2のシール部4に接合され、その他端8bが外部(大気中)に開口するチューブ8で構成された管状通路11と同様である。そして、親水性の菌不透過性フィルター12は、チューブ8の他端8bに配置される。
さらに、消泡フィルター15には、気泡が接触すると破泡するような機能を有する消泡剤が多孔質体等に担持されていることが好ましい。この消泡剤としては、シリコーン(シリカを配合したコンパウンド型、オイル型等)が好適である。なお、多孔質体等に消泡剤を担持する方法としては、消泡剤を含有する液中に多孔質体を含浸させる方法、消泡剤を含有する液を多孔質体等に塗布またはスプレーし、乾燥させる方法などが挙げられる。
図4に示すように、採血器具51(血液バッグシステム)は、採血針53と、採血針53を介して採取された血液を収納する採血バッグ52(貯留部、血液バッグ)と、採血針53と採血バッグ52とを連結する採血ラインと、採血ラインの途中から分岐する分岐ラインと、分岐ラインを介して、採血ラインと連通する初流血を採取(貯留)する検査用血液容器1Aとを備えている。以下、各構成について説明する。なお、検査用血液容器1Aについては前記のとおりであるので、説明を省略する。また、図示しないが、採血器具51は、検査用血液容器1Aの代わりに、検査用血液容器1Bを備えてもよい。
まず、図4に示すように、採血器具51では、クランプ61が開放状態となっているため、分岐チューブ60の採血流路は開放された状態となっている。そして、チューブ58の採血流路は、封止部材59により閉塞した状態となっている。また、検査用血液容器1Aをスタンド等に吊り下げて下垂状態とし、排気部7が上方に位置するようにする。なお、検査用血液容器1Bにおいても同様である。
この場合、封止部材59の中実先端部(図示せず)を破断することによって、封止部材59内の流路を開通させる。この操作により、チューブ58の採血流路が開通状態となり、チューブ57とチューブ58が連通する。これにより、採血された血液が、チューブ57、分岐コネクタ56、封止部材59およびチューブ58を介して、採血バッグ52内に流入する。
