本发明公开了一种股动脉分流灌注管，包括插管主体和扩张器，通过在插管主体上螺纹连接有内螺纹套，内螺纹套两侧壁固定安装有内螺纹柱，便于固定插管主体，使其不易脱出股动脉，在插管主体的右端螺纹连接有挡盘和外螺纹套，在外螺纹套上螺纹连接有密封圈，外螺纹套便于更好的与股动脉体循环主管路连接，密封圈起到更好的密封作用，防止泄露。本发明结构应用于体外循环手术和体外膜肺高级生命支持期间为股动脉远端无灌注缺血区提供血液分流灌注，避免缺血发生。  

The invention discloses a kind of femoral artery shunt infusion tube, including main body and expanders, intubation by threaded connection on the subject of intubation with internal thread, internal thread set of two side wall installation with internal thread column, facilitate fixed intubation subject, make its not easy emergence femoral artery, in the right end of the subject of intubation threaded connections have a baffle plate and the external thread, outer thread on a thread connection with sealing ring, The outer thread sleeve is convenient for better connection with the femoral artery systemic circulation main circuit, and the sealing ring plays a better sealing role to prevent leakage. The structure of the invention is applied to provide blood shunt perfusion to the distal non-perfusion ischemic area of the femoral artery during extracorporeal circulation surgery and ecmo advanced life support to avoid the occurrence of ischemia.
