    • PROBLEM TO BE SOLVED: To provide a fistula catheter, where its body inside fixture parts are made up by inner balloon and outer balloon to make the inner balloon prevent the catheter from getting out of place from the fistula with even if the outer balloon is withered.SOLUTION: The fistula catheter A is composed of a body outside fixture part 10 installed on the abdominal wall surface 36 of a fistula 38, a supply tube 20 having main and supplementary holes 21 and 22, and an internal fixture part 30 swollen by distilled water sent from the supplementary hole 22 provided at the leading end around the supply tube 20. An internal fixture part 30 is composed of inner balloon and outer balloon 31 and 32 communicating with the supplementary hole 22 via an injection ports 22a, 22b provided at the circumferential surface of supply tube 20. Injection ports 22a, 22b are each provided at an unidirectional valves 23, 24 so that the inner balloon and outer balloon 31 and 32 can be charged with distilled water from the supplementary hole 22 via unidirectional valves 23, 24.
    • 要解决的问题:为了提供一种瘘导管,其内部固定部分的内部由内气囊和外气球构成,以使内气囊防止导管从瘘管脱离位置,即使外部 气球枯萎 解决方案:瘘导管A由安装在瘘管38的腹壁表面36上的身体外固定部分10,具有主和辅孔21和22的供应管20和内部固定部分30膨胀组成 通过设置在供给管20的前端的辅助孔22送出的蒸馏水。内部固定部30由内球囊和外球囊31,32构成,外球囊31,32经由喷射口22a,22b与补充孔22连通, 在供应管20的圆周表面上。注入口22a,22b分别设置在单向阀23,24处,使得内球囊和外球囊31和32可以通过单向阀23从补充孔22中充入蒸馏水 ,24.版权所有(C)2013,JPO&INPIT
