PURPOSE: To make it rapidly and easily produce even catheter bodies varying in front end shapes, etc., by fixing a front end cap which is opened with holes to allow the passage of a contrast medium, air and excrement pass and has roundness to the front end of a catheter body internally and separately provided with a contrast medium injecting path, air injecting path and excretion path. CONSTITUTION: The catheter body 2 which is formed to a slender cylindrical shape having elasticity and has a sectional shape continuous with a longitudinal direction is provided with the contrast medium injecting path 6, the air injecting path 7 and the excretion path 8. These paths are partitioned by films 9. The front end cap 3 which is soft and has roundness at the front end is fixed to the front end of the catheter body 2 and the front end cap 3 is provided with the holes 4. The contrast medium injecting tube 14 is freely attachably and detachably connected to the contrast medium injecting projection 24 of a tube connector 18 and the contrast medium is supplied. The air injecting tube 15 is freely attachably and detachably connected to the air injecting projection 25 and the air is fed into the catheter body 2. Further, the excretion tube 16 is connected to the excretion projection 26 to excrete the contrast medium injected into the intestines and the intestinal matter are excreted. |
