Abstract
Disclosed is a plunger rod for a syringe. The plunger rod is useful for sliding a piston within a syringe barrel. The plunger rod is characterized in that it is colored in part or in whole. The syringe is also disclosed. According to such plunger rods, even plural syringes of exactly the same external appearance and configuration can be applied with features that make it possible to readily and visually identify them by simply taking a glance at their appearances without needing a measure such as applying indication members such as labels on them. Further, the use of such plunger rods makes it possible to provide syringes of significantly enhanced visual identifiability without impairing high-level quality, functions, sanitariness and safety required for the syringes.
