PROBLEM TO BE SOLVED: To facilitate the insertion of tubes for injection of various sizes and to make it possible to surely hold the tubes for injection of various sizes. SOLUTION: A nozzle 2 of a convergent circular truncated cone shape having a single tapered angle of 5 to 20 deg. is integrally formed at a cap body 3 having a threaded part 4 to be fitted onto the outer periphery of the mouth part of a pervascular nutrient vessel 3. As a result, even if the diameter of the tube 7 for injection varies with the kinds of transfusion sets, the insertion thereof is easy and the excellent tube holding power is obtainable. |
