ABSTRACT:
The syringe for medicinal purposes features a syringe barrel (1), one end of which is formed as an adapter (2) for a cannula or a closure (3), e.g., in the form of a tip cap, and of a plunger (4), arranged within the syringe barrel (1), and movable by a piston rod (5). At the end of the syringe barrel (1) facing away from the adapter (2), a plunger brake (6) is arranged, which is formed by a rest piece surrounding the syringe barrel (1) and connected removably to it. The rest piece has a projection extending into the lumen of the syringe barrel (1), which forms a stop for the side of the plunger (4) away from the adapter (2).
