A kind of pipe fitting of artificial kidney,It includes: an artificial kidney and two pipe fittings,Wherein,On one artificial kidney,Lower end system is respectively equipped with blood inlet and outlet with axial,And what side is imported and exported equipped with two dialyzates,Two pipe fittings are a L-shape connector,Wherein one combination section of one end formation, which matches to be combined, sets what blood inlet and outlet,The other end then forms interconnecting piece offer blood tube group and sets connection,Thereby,Enabling artificial kidney can pass through L shape pipe fitting can be picked out by blood tube by blood inlet and outlet steering,It avoids the placement position of artificial kidney bad and blood tube is made because bending to there is the situation of obstruction or rupture to generate,In order to increase blood flow into,The smoothness of output,The effect of haemodialysis is substantially improved.一種人工腎臟之管接頭,其包含:一人工腎臟以及二管接頭,其中,一人工腎臟上、下端部係以軸向分別設有一血液進出口,並於側邊設有二透析液進出口,二管接頭均為一呈L狀之接頭,其中一端部形成一組合部配合組設於血液進出口,另一端部則形成一連接部提供血液管組設連結,藉此,令人工腎臟可透過L狀管接頭讓血液管可由血液進出口轉向接出,避免人工腎臟之擺放位置不佳而使血液管因彎折具有阻塞或是破裂之情況產生,俾以增添血液流入、輸出之順暢性,大幅提升血液透析之效果。
