PROBLEM TO BE SOLVED: To maintain the proper amount of an infusion under the application of a simple structure, and allow an easy fixing and detaching work by applying the constitution that the groove of a holding member is released for keeping a catheter in contact with the groove, the catheter is embraced by closing the groove, and a clamping member is formed so as to hold the cylindrical periphery of the holding member. SOLUTION: The holding member 3 of a fixing device is mounted on a catheter led out from the skin. In this case, the holding member 3 is reversed, and the wing pieces 33 thereof are kept up and the slit 32 of the holding member 3 is opened with the wing pieces 33 kept apart from each other. Then, the slit 32 is kept in contact with a catheter fixing position and the wing pieces 33 are released from separation to narrow the slit 32 and hold the catheter with a holding part 31. Released paper 35 is peeled from the reverse side 34 of both wing pieces 33, and the wing pieces 33 are attached to the skin for securing the holding part 31. Then, the knob 42 of a clamping member 4 is moved in the arrow direction, and the inlet of a spring 41 is expanded to a position W2 for fitting it on the holding part 31. Thereafter, the knob 42 is released from operation and the inlet size of the spring 41 is reset to W1, thereby clamping the holding part 31. |
