PROBLEM TO BE SOLVED: To administer two kinds of medicines varying in drug action with one time of pricking to enhance the cost performance by press feeding the pressers corresponding to plural cylindrical bodies to allow the respective medicines to flow out through a hypodermic needle and forming these injection cylinders by one time of injection molding of synthetic resins. SOLUTION: The two flow passages at one front end 23 of the two injection cylinders 21, 22 of the syringe 20 molded by one time of injection molding of the synthetic resins as raw materials are hermetically sealed by a common cap 26. The open port of the other end is closed by pistons 28, 29 and rubber pugs 32, 33 are fitted behind the same. Further, the syringe is covered with a cap 34 from the outside of the cylinders 21, 22 and the rubber pugs 32, 33, by which the structure to withstand any environment change is obtd. At the time of using the medicinal liquids 24, 25 in the cylinders 21, 22, a connector 36 and the hypodermic needle 37 are mounted at the front end 23 and the front ends of the pressers 17 are engaged with the recessed of the pistons 28, 29 and are pushed into both cylinders, by which the medicinal liquids 24, 25 are allowed to flow through the hypodermic needle 37 and are administered to a patient. |
