PROBLEM TO BE SOLVED: To make piercing of a syringe needle, which has been done blindly, easier and surer by enlarging the diameter of the piercing part in a medicinal liquid injection port to be implanted under the skin without enlarging the diameter of the top of the port main body. SOLUTION: This medicinal liquid injection port 1 has an inner room 4 for saving a medicinal liquid. A medicinal liquid injecting orifice 2 with an elastic body 3 is formed above the inner room 4, and a medicine outflow pathway 5 is formed in one radius direction with a connector 6 at the top of the medicine outflow pathway 5 for connecting a catheter. The mounting part 8 of the elastic body 3 above, which forms the main body of the medicine liquid injection port 1, tapers downward at an angle from 15 to 75 degrees, and the elastic body 3 is kept compressed by the tapered form. |
