ABSTRACT:
In medical scenes requiring emergency, where plural medicines are to be injected simultaneously, or solution of solid medicine is to be injected, different kinds of injection agents, without being previously mixed, are accommodated in chambers formed separately in a cylinder. In using a syringe, both injection agents can be sequentially injected separately or mixedly by a simple operation.
