(1) 中空体で構成され、その中空部に連通し、血液が流入する血液流入口と、前記中空部に連通し、前記血液流入口から流入した血液が流出する血液流出口とを有するハウジングと、
前記中空部内に回転可能に収納され、その回転により血液に遠心力を付与する遠心力付与部材とを備える遠心ポンプを製造する製造方法であって、
前記ハウジングは、底部材と蓋部材とを組立てた組立状態で接合されてなるものであり、
前記組立状態とする組立工程と、
前記組立状態で、前記底部材と前記蓋部材との境界部付近にレーザ光を照射することにより、前記底部材と前記蓋部材との融着を行う融着工程とを有することを特徴とする遠心ポンプの製造方法。
前記蓋部材は、前記底部材に向って突出形成され、前記回転中心軸回りに延在する第2の壁部を有し、
前記融着工程では、前記第1の壁部および前記第2の壁部のうちの一方の壁部が他方の壁部の外側に位置した状態で、前記一方の壁部の内周面と前記他方の壁部の外周面とを融着する上記(1)ないし(3)のいずれかに記載の遠心ポンプの製造方法。
前記融着工程では、前記各薄肉部同士を融着する上記(4)に記載の遠心ポンプの製造方法。
前記組立工程に先立って、前記一方の壁部の内周面と前記他方の壁部の外周面とのうちの少なくとも一方の面に光吸収材を供給する光吸収材供給工程を有している上記(4)または(5)に記載の遠心ポンプの製造方法。
前記ハウジング内に回転可能に収納され、その回転により血液に遠心力を付与する遠心力付与部材とを備える遠心ポンプであって、
上記(1)ないし(7)のいずれかに記載の遠心ポンプの製造方法により製造されることを特徴とする遠心ポンプ。
図1は、本発明の遠心ポンプの実施形態を示す断面側面図である。図2は、本発明の遠心ポンプの実施形態を示す断面平面図である。図3は、本発明の遠心ポンプの製造方法を示す縦断面図であって、用意工程を示す図である。図4は、本発明の遠心ポンプの製造方法を示す縦断面図であって、接合工程を示す図である。図5は、本発明の遠心ポンプの製造方法を示す縦断面図であって、図3に示すハウジングの部分拡大図である。図6は、本発明の遠心ポンプの製造方法を示す縦断面図であって、図4に示すハウジングの部分拡大図である。
遠心ポンプ1の製造方法は、[1]用意工程と、[2]光吸収材供給工程と、[3]組立工程と、[4]接合工程とを備えている。
図3および図4に示すように、まず、底部材21、蓋部材22、回転体3、支持機構4および治具8を用意する。
次に、図5に示すように、レーザ光を吸収する光吸収材200を蓋部材22の薄肉部223の表面に塗布(供給)する。光吸収材200としては、例えば、カーボンブラック等の粉末、該粉末や後述する染料を含む液状(ペースト状)のもの、または該粉末や該染料を含むシート状(層状)のものが挙げられる。
図4に示すように、回転体3および支持機構4を内側に収納するように、底部材21および蓋部材22を組立てる。このとき、蓋部材22の外周面223aは、底部材21の内周面212aによって案内されるため、底部材21に対して容易に位置決めされる。これにより、容易に組立状態とすることができる。
次に、図6に示すように、レーザ光Lを光吸収材200に向って照射する。レーザ光Lは、底部材21の薄肉部212を透過して、光吸収材200に照射される。光吸収材200に照射されたレーザ光Lは、効率良く光吸収材200に吸収され、熱に変わるので、低出力で効率的に融着を行うことができる。
