    • PROBLEM TO BE SOLVED: To provide a novel syringe suitable especially for ophthalmic injections, keeping convenience in use while contents are well sealed.SOLUTION: A syringe 1 is suitable for use in ophthalmic injections. The syringe 1 includes a trunk 2, a stopper 10 and a plunger 4. The syringe 1 is extended along a first axis A. The trunk 2 has an outlet 12 at an outlet end part 14, and the stopper 10 is disposed in the trunk 2 so that a front 16 of the stopper 10 and the trunk 2 determine a boundary of a capacity variable inner chamber 18. The capacity variable inner chamber 18 contains an injection medicament 20 containing a solution for ophthalmology containing VEGF antagonist such as Ranibizumab. The injection liquid 20 can be discharged through the outlet 12 by the movement toward an outlet end part 14 of the stopper 10, so that the capacity of the capacity variable inner chamber 18 decreases. The plunger 4 includes a plunger contact surface 22 at a first end part 24 and a rod 26 extended between the plunger contact surface 22 and a rear part 25.
    • 要解决的问题:提供一种特别适用于眼科注射的新型注射器,保持使用方便,同时内容物密封良好。解决方案:注射器1适用于眼科注射。 注射器1包括躯干2,止动件10和柱塞4.注射器1沿着第一轴线A延伸。躯干2在出口端部14处具有出口12,止动件10设置在躯干 2,使得止动件10的前部16和躯干2确定容量可变内腔18的边界。容量可变内腔18包含含有含有VEGF拮抗剂如兰尼珠单抗的眼科溶液的注射药剂20。 注射液20可以通过朝向止动件10的出口端部14的移动而通过出口12排出,使得容量可变内腔18的容量减小。 柱塞4包括在第一端部24处的柱塞接触表面22和延伸在柱塞接触表面22和后部25之间的杆26。
