一种冠状静脉窦抽吸导管
摘要：
本发明提供了一种冠状静脉窦抽吸导管，包括导管头段和延伸管，所述导管头段和延伸管均为中空管状结构，所述导管头段具有近端和远端，所述延伸管与导管头段近端延续，所述导管头段和延伸管远段呈近似弧形结构，其中导管头段长约4-7cm，包括圆弧段和折弯段，其顶端小(3-6F)，往近端管径逐渐变粗(6F-9F)，且距顶端0.5-1.5cm处有一个15-45°小折弯，折弯至顶端为直行结构或稍有弧度。所述导管头段上设置有流通孔，包括顶端端孔和四周管壁若干侧孔。所述导管头段自远端至近端间隔等距离设置有不透X光标识点。进入导管头段内的血液借助体外负压装置，通过直径一致的延伸管将血液引流出来，体外开口处有接口，与其它器械相连。
摘要（英）：

The invention provides a coronary venous sinus suction catheter which comprises a catheter head section and an extension tube. Each of the catheter head section and the extension tube is of a hollow tubular structure, the catheter head section has a near end and a far end, the extension tube is connected with the near end of the catheter head section, the catheter head section and the far end of the extension tube are approximately of an arc-shaped structure, the catheter head section is about 4-7 cm in length and comprises a circular arc section and a bent section, the top end of the catheter head section is small (3-6F), tube diameter close to the near end gradually thickens (6-9F), a small bend of 15-45 degrees is formed at a position of 0.5-1.5 cm from the top end, a space from the bend to the top end is of a linear structure or has a slight radian. Circulation holes are formed in the catheter head section and include a top end hole and a plurality of side holes in the tube wall around, and X-ray-tight identity points are arranged from the far end to the near end of the catheter head section at equal intervals. Blood in the catheter head section is drained through the extension tube uniform in diameter with the help of an in-vitro negative pressure device, and a port is arranged at an in-vitro opening and connected with other instruments.
