<P>PROBLEM TO BE SOLVED: To provide an injection implement for medical use which is capable of preventing time and effort for calculation and calculation mistake from being generated when a necessary amount of dosage to a patient is measured from a pre-filled syringe, and a dosing system using this. <P>SOLUTION: A first syringe 2a is connected for example, with a second syringe 2b in which a chemical liquid L is stored in advance. The first syringe 2a includes: an outer cylinder 21 on which an opening part 211 is formed; and a connector 3 having a second port 6 connected with the second syringe 2b. The second port 6 includes: a needle tube 61; a covering member 62 formed of an elastic member covering the surrounding of the needle tube 61; and a protective member 63 forming a cylindrical shape and for covering the surrounding of the covering member 62. Under an initial condition where the second port 6 is not mounted on the second syringe 2b, the covering member 62 seals the needle tube 61, and under a mounting condition where the second port 6 is mounted on the second syringe 2b, the needle tube 61 penetrates through the covering member 62, and the second syringe 2b and the outer cylinder 21 are communicating with each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
